SUMMARY: We are adopting a new airworthiness directive (AD) for all The
Boeing Company Model 757 airplanes. This AD was prompted by reports of
fractured rudder pedal pushrod connecting bolts in a rudder pedal
assembly. This AD requires repetitive replacements of the rudder pedal
pushrod connecting bolts and repetitive inspections of the rudder pedal
assembly bolt holes in each of the captain and the first officer rudder
pedal assemblies, and if necessary, repair or replacement of worn
rudder pedal assemblies. We are issuing this AD to prevent fracture of
the rudder pedal pushrod connecting bolts during pedal use, which could
result in large involuntary inputs to the rudder and nose-wheel
steering and an asymmetric application of braking, if pedal brakes are
applied, leading to a runway excursion.
DATES: This AD is effective April 22, 2014.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to all The Boeing Company
Model 757 airplanes. The NPRM published in the Federal Register on May
10, 2013 (78 FR 27315). The NPRM was prompted by reports of fractured
rudder pedal pushrod connecting bolts in a rudder pedal assembly. The
NPRM proposed to require repetitive
[[Page 14988]]
replacements of the rudder pedal pushrod connecting bolts and
repetitive inspections of the rudder pedal assembly bolt holes in each
of the captain and the first officer rudder pedal assemblies, and if
necessary, repair or replacement of worn rudder pedal assemblies. We
are issuing this AD to prevent fracture of the rudder pedal pushrod
connecting bolts during pedal use, which could result in large
involuntary inputs to the rudder and nose-wheel steering and an
asymmetric application of braking, if pedal brakes are applied, leading
to a runway excursion.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the proposal
(78 FR 27315, May 10, 2013) and the FAA's response to each comment.
Request To Reduce the Compliance Time
Air Line Pilots Association International (the commenter) stated
that it agrees with the intent of the NPRM (78 FR 27315, May 10, 2013),
but requested that we reduce the compliance time from 60 months to 24
months. The commenter provided no justification for this request.
We disagree with the request to revise the compliance time in this
final rule. In developing the compliance time for this final rule, we
considered not only the safety implications of the identified unsafe
condition, but also the average utilization rate of the affected fleet,
the practical aspects of an orderly modification of the fleet, the
availability of required parts, and the time necessary for the
rulemaking process. We find that the compliance time, as proposed,
adequately represents an appropriate interval of time in which the
required actions can be performed in a timely manner within the
affected fleet, while still maintaining an adequate level of safety. We
have not changed this final rule in this regard.
Request To Clarify the Unsafe Condition
Boeing requested that we revise the unsafe condition in the NPRM
(78 FR 27315, May 10, 2013), and suggested language to clarify the
expectation of asymmetric braking, in the event of fracture of the
subject bolt. Boeing added that symmetric braking inputs prior to
fracture can become asymmetric following bolt fracture due to loss of
brake inputs on the affected side.
We agree with the request to revise the unsafe condition for the
reasons provided by Boeing. We have revised this final rule to reflect
the revised language.
Request To Use One Service Bulletin Revision
Aviation Technical Services, Inc. (the commenter) requested that we
revise the NPRM (78 FR 27315, May 10, 2013) to mandate only one version
of the service information. The commenter also requested that we
require that Boeing combine both versions of the service bulletin
specified in the NPRM, into one final revision. The commenter reasoned
that having two versions of the service bulletin will require operators
and maintenance providers to integrate the two service bulletins in
order to comply with the NPRM. The commenter expressed that this burden
should be on the original equipment manufacturer (OEM) and the FAA.
The commenter also requested that to further determine the adequacy
of Boeing Alert Service Bulletin 757-27A0153, dated May 9, 2012, as
revised by Boeing Alert Service Bulletin 757-27A0153, Revision 1, dated
October 29, 2012, the FAA should use its own guidance, as provided by
FAA Advisory Circular (AC) 20-176, dated December 19, 2011 (http://
rgl.avs.faa.gov/Regulatory--and--Guidance--Library/
rgAdvisoryCircular.nsf/0/a78cc91a47b192278625796b0075f419/$FILE/
AC%2020-176.pdf).
We disagree with the request to provide a single service bulletin
version for the required method of compliance. Boeing Alert Service
Bulletin 757-27A0153, Revision 1, dated October 29, 2012, includes only
minor corrections to washer part numbers in top kit 012N8932-21 and an
additional instruction for getting better access, if necessary, for the
detailed inspections required by this final rule. It is not necessary
that Boeing combine both revisions of the referenced service bulletin
into one final revision.
Also, the design approval holder (DAH) followed the guidance in FAA
AC 20-176, dated December 19, 2011 (http://rgl.avs.faa.gov/Regulatory--
and--Guidance--Library/rgAdvisoryCircular.nsf/0/
a78cc91a47b192278625796b0075f419/$FILE/AC%2020-176.pdf). We approved
Boeing Alert Service Bulletin 757-27A0153, dated May 9, 2012, as
revised by Boeing Alert Service Bulletin 757-27A0153, Revision 1, dated
October 29, 2012, using the guidance in FAA Order 8110.117, dated
September 12, 2012 (http://rgl.avs.faa.gov/Regulatory--and--Guidance--
Library/rgOrders.nsf/0/984bb9eb07cdd86986257a7f0070744c/$FILE/
Order%208110.117.pdf). (Refer to Section 2-11, ``Streamlining
Development and Revision of SBs,'' paragraph (c)(5), ``Partial Revision
Process--A process in which only changed information in a service
bulletin is sent to affected customers,'' of FAA AC 20-176, dated
December 19, 2011.) We have not changed this final rule in this regard.
Request for Additional Guidance
Aviation Technical Services, Inc. (the commenter) requested that we
revise the NPRM (78 FR 27315, May 10, 2013) to provide sufficient
instruction to determine the installation finish associated with the
replacement bushing for the rudder pedal pushrod. The commenter
reasoned that the instructions provided by Boeing Alert Service
Bulletin 757-27A0153, dated May 9, 2012, as revised by Boeing Alert
Service Bulletin 757-27A0153, Revision 1, dated October 29, 2012, refer
to Boeing Standard Overhaul Practices Manual (SOPM) 20-50-03 for the
shrink fit procedure to install repair bushings, and that the SOPM
procedure contain instructions such as: ``Apply the specified
installation finish. . . .'' and ``Refer to the overhaul instructions
for applicable operations. . . .'' The commenter asserted that neither
Boeing Alert Service Bulletin 757-27A0153, dated May 9, 2012, as
revised by Boeing Alert Service Bulletin 757-27A0153, Revision 1, dated
October 29, 2012, nor the SOPM provide sufficient instruction to
determine the installation finish associated with the replacement
bushing for the rudder pedal pushrod.
We disagree to revise this final rule. Step 4 of Figures 3 and 4 of
the Accomplishment Instructions of Boeing Alert Service Bulletin 757-
27A0153, dated May 9, 2012, as revised by Boeing Alert Service Bulletin
757-27A0153, Revision 1, dated October 29, 2012, already provides
procedures for installing bushing 001N0004-1 with BMS 5-95 sealant, as
specified in ``the shrink fit'' procedure referred to in Standard
Overhaul Practices Manual (SOPM) 20-50-03 (bushing 001N0004-1 is
already finished). SOPM 20-50-03 Bearing and Bushing Replacement,
Paragraph 7.B, ``Shrink Fit (Temperature Differential) Procedure,''
specifies, among other things, to apply the specified installation
finish ``as specified in Paragraph 6B,'' which, in turn, specifies
``Installation with sealant.'' The finish is, in this case, the sealant
that is used during the installation (BMS 5-95). Therefore, Boeing
Alert Service Bulletin 757-27A0153, dated May 9, 2012, as revised by
Boeing Alert Service Bulletin 757-27A0153, Revision 1, dated October
29,
[[Page 14989]]
2012, in combination with SOPM 20-50-03, provide sufficient
instructions to install the bushing. We have not changed the AD in this
regard.
Request To Match Terminology
American Airlines (AAL) requested that we revise the NPRM (78 FR
27315, May 10, 2013) to match certain wording in Boeing Alert Service
Bulletin 757-27A0153, dated May 9, 2012, as revised by Boeing Alert
Service Bulletin 757-27A0153, Revision 1, dated October 29, 2012. AAL
explained that Boeing Alert Service Bulletin 757-27A0153, dated May 9,
2012, as revised by Boeing Alert Service Bulletin 757-27A0153, Revision
1, dated October 29, 2012, refers to bolt part number (P/N)
BACB30NM5DK47 as changed to P/N BACB30UU5K48D as the rudder pedal
pushrod bolt, while the NPRM refers to this part number as the rudder
pedal pushrod connecting bolt. AAL expressed that matching the
terminology in Boeing Alert Service Bulletin 757-27A0153, dated May 9,
2012, as revised by Boeing Alert Service Bulletin 757-27A0153, Revision
1, dated October 29, 2012, would eliminate any possible confusion.
We disagree with the request to match the terminology in this final
rule with the terminology found in Boeing Alert Service Bulletin 757-
27A0153, dated May 9, 2012, as revised by Boeing Alert Service Bulletin
757-27A0153, Revision 1, dated October 29, 2012. The word
``connecting'' was added in the NPRM (78 FR 27315, May 10, 2013) to
further clarify that this bolt secures the rudder pedal arm to the
rudder pushrod. We have not changed this final rule in this regard.
Request To Use Specific Instructions
AAL requested that we revise the NPRM (78 FR 27315, May 10, 2013)
to require only those instructions that correct the unsafe condition.
AAL explained that paragraphs (g) and (h) of the NPRM are more
restrictive than necessary to ensure safety of flight, and that the
Accomplishment Instructions of Boeing Alert Service Bulletin 757-
27A0153, dated May 9, 2012, as revised by Boeing Alert Service Bulletin
757-27A0153, Revision 1, dated October 29, 2012, should not be mandated
in their entirety.
AAL requested the following revisions to certain paragraphs of the
NPRM (78 FR 27315, May 10, 2013):
<bullet> Since paragraph (g) of the NPRM (78 FR 27315, May 10,
2013) specified a detailed inspection of the rudder pedal assembly bolt
holes, the only procedure that should be mandated by this paragraph is
FIGURE 1 of the Accomplishment Instructions of Boeing Alert Service
Bulletin 757-27A0153, dated May 9, 2012, as revised by Boeing Alert
Service Bulletin 757-27A0153, Revision 1, dated October 29, 2012.
<bullet> Since paragraph (h)(1) of the NPRM (78 FR 27315, May 10,
2013) specified replacement of a new bolt, washer, nut, and cotter pin,
the only procedure that should be mandated by this paragraph is FIGURE
2 of the Accomplishment Instructions of Boeing Alert Service Bulletin
757-27A0153, dated May 9, 2012, as revised by Boeing Alert Service
Bulletin 757-27A0153, Revision 1, dated October 29, 2012.
<bullet> Paragraph (h)(2)(i) of the NPRM (78 FR 27315, May 10,
2013) should be revised as follows: ``Install a new rudder pedal
assembly in accordance with `Condition 2' of the Accomplishment
Instructions of Boeing Alert Service Bulletin 757-27A0153, dated May 9,
2012, as revised by Boeing Alert Service Bulletin 757-27A0153, Revision
1, dated October 29, 2012; or install a bushing in the worn hole in
accordance with FIGURE 3 of the Accomplishment Instructions of Boeing
Alert Service Bulletin 757-27A0153, dated May 9, 2012, as revised by
Boeing Alert Service Bulletin 757-27A0153, Revision 1, dated October
29, 2012.''
<bullet> Paragraph (h)(2)(ii) of the NPRM (78 FR 27315, May 10,
2013) specified installation of a new bolt, washer, nut, and cotter pin
in accordance with the Accomplishment Instructions of Boeing Alert
Service Bulletin 757-27A0153, dated May 9, 2012, as revised by Boeing
Alert Service Bulletin 757-27A0153, Revision 1, dated October 29, 2012.
However, Boeing Alert Service Bulletin 757-27A0153, dated May 9, 2012,
as revised by Boeing Alert Service Bulletin 757-27A0153, Revision 1,
dated October 29, 2012, does not provide explicit instructions to
replace the bolt, washer, nut, and cotter pin in the event that the
diameter of only one hole is greater than 0.3140 inch. There is only a
note in the procedure to make sure to discard the existing hardware,
and to install new hardware as provided in Boeing Kit 0l2N8932-21.
AAL has determined that the instructions provided in FIGURE 2 of
the Accomplishment Instructions of Boeing Alert Service Bulletin 757-
27A0153, dated May 9, 2012, as revised by Boeing Alert Service Bulletin
757-27A0153, Revision 1, dated October 29, 2012, contain the proper
instructions and part numbers to replace the bolt, washer, nut, and
cotter pin to correct the unsafe condition. Therefore, the only
procedure that should be mandated by this paragraph is FIGURE 2 of the
Accomplishment Instructions of Boeing Alert Service Bulletin 757-
27A0153, dated May 9, 2012, as revised by Boeing Alert Service Bulletin
757-27A0153, Revision 1, dated October 29, 2012.
<bullet> Paragraph (h)(3)(i) of the NPRM (78 FR 27315, May 10,
2013) should be revised as follows: ``Install a new rudder pedal
assembly in accordance with `Condition 2' of the Accomplishment
Instructions of Boeing Alert Service Bulletin 757-27A0153, dated May 9,
2012, as revised by Boeing Alert Service Bulletin 757-27A0153, Revision
1, dated October 29, 2012, or install two bushings in the two worn
holes in accordance with FIGURE 4 of the Accomplishment Instructions of
Boeing Alert Service Bulletin757-27A0153, dated May 9, 2012, as revised
by Boeing Alert Service Bulletin 757-27A0153, Revision 1, dated October
29, 2012.''
<bullet> Paragraph (h)(3)(ii) of the NPRM (78 FR 27315, May 10,
2013) requires installation of a new bolt, washer, nut, and cotter pin
in accordance with the Accomplishment Instructions of Boeing Alert
Service Bulletin 757-27A0153, dated May 9, 2012, as revised by Boeing
Alert Service Bulletin 757-27A0153, Revision 1, dated October 29, 2012.
However, Boeing Alert Service Bulletin 757-27A0153, dated May 9, 2012,
as revised by Boeing Alert Service Bulletin 757-27A0153, Revision 1,
dated October 29, 2012, does not provide explicit instructions to
replace the bolt, washer, nut, and cotter pin in the event that the
diameters of both holes are greater than 0.3140 inch. Again, there is
only a note in the procedure to make sure to discard the existing
hardware, and to install new hardware as provided in Boeing Kit
012N8932-21.
AAL has determined that the instructions provided in FIGURE 2 of
the Accomplishment Instructions of Boeing Alert Service Bulletin 757-
27A0153, dated May 9, 2012, as revised by Boeing Alert Service Bulletin
757-27A0153, Revision 1, dated October 29, 2012, contain the proper
instructions and part numbers to replace the bolt, washer, nut, and
cotter pin to correct the unsafe condition. Therefore, the only
procedure that should be mandated by this paragraph is FIGURE 2 of the
Accomplishment Instructions of Boeing Alert Service Bulletin 757-
27A0153, dated May 9, 2012, as revised by Boeing Alert Service Bulletin
757-27A0153, Revision 1, dated October 29, 2012.
We agree with the concept of minimizing AD requirements when
appropriate. However, we do not agree with AAL's request. The FAA
worked in conjunction with industry, under the Airworthiness Directives
Implementation Aviation Rulemaking Committee (ARC), to enhance the AD
system. One enhancement is a new
[[Page 14990]]
process for annotating which steps in the service information are
``required for compliance'' (RC) with an AD. Differentiating these
steps from other tasks in the service information is expected to
improve an owner's/operator's understanding of AD requirements and help
provide consistent judgment in AD compliance.
In response to the AD Implementation ARC, the FAA released AC 20-
176, dated December 19, 2011 (http://rgl.avs.faa.gov/Regulatory--and--
Guidance--Library/rgAdvisoryCircular.nsf/0/
a78cc91a47b192278625796b0075f419/$FILE/AC%2020-176.pdf); and Order
8110.117, dated September 12, 2012 (http://rgl.avs.faa.gov/Regulatory--
and--Guidance--Library/rgOrders.nsf/0/984bb9eb07cdd86986257a7f0070744c/
$FILE/Order%208110.117.pdf), which include the concept of RC. The FAA
has begun implementing this concept in ADs when we receive service
information containing RC steps. While some design approval holders
have implemented the RC concept, the implementation is voluntary. The
FAA does not intend to develop or revise AD requirements to incorporate
the RC concept if it is not included in the service information.
Contrary to AAL's statement that ADs should mandate only those
service bulletin provisions that are ``necessary to ensure safety of
flight,'' ADs generally contain requirements that are reasonably
related to addressing the unsafe condition, as determined by the FAA
and the design approval holder that developed the service bulletin.
Typically, operators' maintenance programs were not developed in
recognition of the unsafe condition that is being addressed by an AD.
Whenever we issue an AD, those programs had failed to prevent the
unsafe condition in the first place. Therefore, many provisions of ADs
address aspects of accomplishing the required maintenance that are
necessary to prevent operators from inadvertently aggravating the
unsafe condition or introducing new unsafe conditions.
For many years, the Air Transport Association (now Airlines for
America, A4A) has sponsored the ``Lead Airline'' program through which
individual airlines are provided an opportunity to prototype
manufacturers' draft service instructions before they are finalized.
One objective of this activity is to minimize the procedures included
in the instructions that are considered unnecessary. Therefore, when
the FAA receives a manufacturer's service bulletin, we recognize that
the procedures specified have been determined to be necessary by both
the manufacturer and affected operators. As in this case, the
instructions provided in service bulletins referenced in ADs are
reasonably related to addressing the unsafe condition.
As always, if AAL or any other operator prefers to address the
unsafe condition by means other than those specified in the referenced
service information, they may request approval for an alternative
method of compliance and, if approved, may use it instead of the
procedures specified in the service information.
Therefore, no changes have been made to this final rule in this
regard.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this AD with the changes described previously and minor editorial
changes. We have determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM (78 FR 27315, May 10, 2013) for correcting the unsafe condition;
and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (78 FR 27315, May 10, 2013).
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this AD.
Costs of Compliance
We estimate that this AD affects 685 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

The on-condition costs in the table above are per rudder pedal
assembly. Depending on the diameter of the holes found during the
inspection, it may be necessary to replace or repair the rudder pedal
assemblies. The parts cost to replace or repair the rudder pedal
assemblies are not included in the estimate; it is considered ``Parts &
Materials Supplied by the Operator,'' which is referenced in Boeing
Alert Service Bulletin 757-27A0153, dated May 9, 2012, as revised by
Boeing Alert Service Bulletin 757-27A0153, Revision 1, dated October
29, 2012.
According to the manufacturer, some of the costs of this AD may be
covered under warranty, thereby reducing the cost impact on affected
individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs,
describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
This AD will not have federalism implications under Executive Order
13132. This AD will not have a substantial direct effect on the States,
on the relationship between the national government and the States, or
on the distribution of power and responsibilities among the various
levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
2014-05-20 The Boeing Company: Amendment 39-17793; Docket No. FAA-
2013-0369; Directorate Identifier 2012-NM-128-AD.
(a) Effective Date
This AD is effective April 22, 2014.
(b) Affected ADs
Certain requirements of this AD terminate the requirements of AD
2001-22-13, Amendment 39-12492 (66 FR 55075, November 1, 2001), for
Model 757 airplanes.
(c) Applicability
This AD applies to all The Boeing Company Model 757-200, -200PF,
-200CB, and -300 series airplanes, certificated in any category.
(d) Subject
Air Transport Association (ATA) of America Code 27, Flight
Controls.
(e) Unsafe Condition
This AD was prompted by reports of fractured rudder pedal
pushrod connecting bolts in the rudder pedal assembly. We are
issuing this AD to prevent fracture of the rudder pedal pushrod
connecting bolts during pedal use, which could result in large
involuntary inputs to the rudder and nose-wheel steering and an
asymmetric application of braking, if pedal brakes are applied,
leading to a runway excursion.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Inspection
Within 60 months after the effective date of this AD, do a
detailed inspection of the rudder pedal assembly bolt holes to
determine the diameter in each of the captain and the first officer
rudder pedal assemblies, in accordance with the Accomplishment
Instructions of Boeing Alert Service Bulletin 757-27A0153, dated May
9, 2012, as revised by Boeing Alert Service Bulletin 757-27A0153,
Revision 1, dated October 29, 2012. Repeat this inspection
thereafter at intervals not to exceed 15,000 flight cycles.
(h) Installation
Do the applicable actions specified in paragraph (h)(1), (h)(2),
or (h)(3) of this AD for each of the captain and first officer
rudder pedal assemblies, based on the results of any inspection
required by paragraph (g) of this AD. Accomplishment of paragraph
(h)(1), (h)(2), or (h)(3) of this AD terminates the requirements of
AD 2001-22-13, Amendment 39-12492 (66 FR 55075, November 1, 2001),
for that Model 757 airplane only.
(1) If the diameters of both holes are within 0.3120 and 0.3140
inch on the assembly, before further flight, install a new rudder
pedal pushrod connecting bolt, washer, nut, and cotter pin, in
accordance with the Accomplishment Instructions of Boeing Alert
Service Bulletin 757-27A0153, dated May 9, 2012, as revised by
Boeing Alert Service Bulletin 757-27A0153, Revision 1, dated October
29, 2012.
(2) If the diameter of only one hole is greater than 0.3140 inch
on the assembly, before further flight, do the actions specified in
paragraphs (h)(2)(i) and (h)(2)(ii) of this AD.
(i) Install a new rudder pedal assembly, or install a bushing in
the worn hole, in accordance with the Accomplishment
