Federal Register Abstract
The FAA is adopting a new airworthiness directive (AD) for Model 757-200, -200PF, -200CB, and -300 series airplanes. This AD requires an inspection of the two spring arms in the spin brake assemblies in the nose wheel well to determine if the spring arms are made of aluminum or composite material, and repetitive related investigative/corrective actions if necessary. This AD also provides options for terminating the repetitive actions. This AD results from reports of cracked and broken aluminum springs. We are issuing this AD to detect and correct cracked or broken springs. A cracked or broken spring could separate from the airplane and result in potential hazard to persons or property on the ground, or ingestion into the engine with engine damage and potential shutdown, or damage to the airplane.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
Model 757-200, -200PF, -200CB, and -300 series airplanes. This AD
requires an inspection of the two spring arms in the spin brake
assemblies in the nose wheel well to determine if the spring arms are
made of aluminum or composite material, and repetitive related
investigative/corrective actions if necessary. This AD also provides
options for terminating the repetitive actions. This AD results from
reports of cracked and broken aluminum springs. We are issuing this AD
to detect and correct cracked or broken springs. A cracked or broken
spring could separate from the airplane and result in potential hazard
to persons or property on the ground, or ingestion into the engine with
engine damage and potential shutdown, or damage to the airplane.
DATES: This AD becomes effective February 16, 2011.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of February 16,
2011.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a supplemental notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an AD that would apply to all Model
757-200, -200PF, -200CB, and -300 series airplanes. That supplemental
NPRM was published in the Federal Register on October 19, 2009 (74 FR
53430). The original NPRM proposed to require an inspection of the two
spring arms in the spin brake assemblies in the nose wheel well to
determine if the spring arms are made of aluminum or composite
material, and repetitive related investigative/corrective actions if
necessary. The original NPRM also would have provided for optional
terminating actions for the repetitive inspections. The supplemental
NPRM proposed to require revising the original NPRM to include a parts
installation paragraph and to provide options for terminating the
repetitive actions.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received on the
supplemental NPRM. Continental Airlines had no additional comments
beyond what was previously submitted in the supplemental NPRM.
Request To Revise Delegation of Authority
Boeing requested that we revise the Delegation Option Authorization
(DOA) holder to Boeing Commercial Airplanes Organization Designation
Authorization (ODA) in paragraph (l)(3) of the supplemental NPRM.
We agree with Boeing's request to revise the delegation of
authority. Boeing Commercial Airplanes has received an ODA, which
replaces the previous designation as a DOA holder. We have revised
paragraph (m)(3) of this AD (paragraph (l)(3) of the supplemental NPRM)
to add delegation of authority to Boeing Commercial Airplanes ODA to
approve an alternative method of compliance (AMOC) for any repair
required by this AD.
Request To Revise the AD To Permit the Accomplishment of Paragraph (k)
of this AD in a Shop Environment
American Airlines (AAL) requested that the supplemental NPRM permit
the accomplishment of paragraph (j) of the supplemental NPRM, ``Parts
Installation,'' in a shop environment. AAL stated that paragraph (j) of
the supplemental NPRM (paragraph (k) of this AD) presents several
issues that need resolution. AAL stated that the Accomplishment
Instructions of Boeing Special Attention Service Bulletin 757-32-0176,
Revision 1, dated October 16, 2008, are applicable to an on-wing
inspection with no provisions for shop instructions.
AAL also stated that paragraph 3.B.5.a. of Boeing Special Attention
Service Bulletin 757-32-0176, Revision 1, dated October 16, 2008,
contains multiple areas of concern. AAL stated that the service
bulletin instructs operators to ``Replace the left or right (as
applicable) aluminum spring with a new aluminum spring in accordance
with FIGURE 4 * * *.'' However, AAL stated that this figure provides
instructions to replace the spring on-wing. AAL stated that it has
processes in place by which the spring assembly (141N0091-22) is
reworked (to include any necessary spring replacement) in accordance
with Boeing drawing data in a shop environment. AAL stated that the
supplemental NPRM contains no
[[Page 1980]]
provisions for accomplishing this spring replacement in a shop
environment. AAL requested that the final rule contain appropriate
language to allow operators to accomplish the intent of Figure 4 of the
service bulletin in a shop environment.
We disagree with AAL's request to include language specifying that
the accomplishment of paragraph (k) of this AD is permitted in a shop
environment. Although the final installation of the spin brakes is
required by this AD and installation may be accomplished in a shop
environment, AD compliance is established for airplanes and not parts.
AAL may perform shop maintenance provided that the AD is complied with
and the airplane meets the requirements of this AD.
In addition, the service bulletin does not provide for inspections
and replacement of parts in a shop environment where the installation
of the spin brake assemblies could be accomplished off the airplane.
The commenter does not provide sufficient suggestions to demonstrate
and ensure that the corrected assemblies could be installed such that
each affected airplane could demonstrate compliance. An operator may
request approval of an alternative method of compliance (AMOC) in
accordance with the provisions of paragraph (m) of this AD for brake
assemblies that were re-worked off the airplane. No changes to the AD
have been made in this regard.
Request To Allow Replacement of the Existing Spin Brake Assembly With a
Serviceable Spin Brake Assembly
AAL stated that there is an omission from paragraph 3.B.5.a. of
Boeing Special Attention Service Bulletin 757-32-0176, Revision 1,
dated October 16, 2008. AAL stated that the paragraph allows
replacement of the existing spin brake assembly with a new spin brake
assembly in accordance with the Boeing 757 Airplane Maintenance Manual,
but no provisions are made for installing a serviceable (used) spin
brake.
From these comments we infer that AAL is requesting that we revise
the final rule to also allow replacement of an existing spin brake
assembly with a serviceable assembly. We agree with AAL that a
serviceable spin brake assembly is acceptable for compliance. We have
added paragraph (j) of this AD to allow replacement with a serviceable
spin brake assembly if the assembly is inspected and all applicable
related investigative and corrective actions have been applied in
accordance with the requirements of paragraph (g) of this AD.
Request To Use Part Substitutions
AAL requested that we revise the supplemental NPRM to allow use of
approved part substitutions for accomplishing the proposed actions. AAL
stated that where common hardware such as washers, nuts, bolts, shims,
sealants, and adhesives are specified in Boeing Special Attention
Service Bulletin 757-32-0176, Revision 1, dated October 16, 2008,
operators with accepted processes may use approved substitutes
determined to be equivalent in accordance with the operator parts
management systems. AAL stated that this will eliminate a duplication
of effort for all parties, including the operators, Boeing, and the
engineering branch of the Seattle Aircraft Certification Office by
avoiding unnecessary requests for AMOCs to allow equivalent hardware.
AAL stated that many operators, including AAL, have an FAA-accepted
process by which they combine certain parts that have been determined
to be equivalent and are placed in inventory under a single company
part number. AAL stated that this process is longstanding and is done
to facilitate an efficient inventory system. AAL also stated that the
parts disposition authority (PDA) for American Airlines is contained in
the engineering procedures manual (EPM), which is incorporated into the
general manual (GM). AAL stated that the GM is required by the FAA-
approved operations specification. AAL stated that Section 15-20 of the
EPM defines the process by which part equivalency can be established.
The basis for equivalency is found in source documents provided by the
original equipment manufacturer (OEM), such as the Boeing Spec-2000,
Boeing Document D-590, Boeing qualified product list (QPL), the
applicable aircraft illustrated parts catalog (IPC), or industry
standard specifications such as military specification (MS), National
Aerospace Standards (NAS), Army Navy (AN), Society of Automotive
Engineers (SAE), etc., or other qualified data provided by the OEM. AAL
also stated that in any case where equivalency is clearly unambiguous,
AAL engineering will use these and other FAA-approved sources such as
OEM drawings, specifications, OEM correspondence, or parts manufacturer
approval (PMA) authorizations to determine the interchangeability of
parts. AAL stated that while some of the above documents have been
included as notes in applicable service bulletins in order to provide
equivalency, it has found a number of cases where, during
accomplishment of an AD, there was not sufficient information provided
to make that assessment.
We disagree with AAL's request to use part substitutions for
accomplishing the actions in this AD. The requested list of substitute
parts and materials is extensive and uncontrolled--and, in many cases,
not FAA approved. An operator may request approval of an AMOC in
accordance with the provisions of paragraph (m) of this AD. We have not
changed this AD regarding this issue.
Request To Revise the Phrase ``Investigative and Corrective Actions''
Northwest Airlines (NWA) requested that we revise the phrase
``investigative and corrective actions'' in the supplemental NPRM. NWA
stated that the use of the phrase ``investigative and corrective
actions'' in paragraphs (g) and (j) of the supplemental NPRM may lead
to confusion as to what action(s) in the service instructions are
required. NWA proposed that the phrase be changed to ``compliance
action'' in paragraph (g) of the supplemental NPRM, and that the phrase
should be removed from paragraph (j) of the supplemental NPRM. NWA
stated that the term ``investigative and corrective actions'' is not
used in the service instructions and is not defined in the supplemental
NPRM. NWA stated that in the process task flow of the service
instructions, the ``determination'' or ``investigation'' of spring
material type was identified earlier in paragraph (g) of the
supplemental NPRM, and the tasks that remain to be accomplished are
compliance actions (inspect or replace), and not investigative actions.
We disagree with NWA's request to revise the phrase ``investigative
and corrective actions.'' This terminology was defined in the Relevant
Service Information section of the original NPRM. The ``related
investigative and corrective actions'' include repetitive detailed and
high frequency eddy current inspections for cracking of the aluminum
spring arm, and the corrective action is replacing the spring arm with
a new spring arm made of either aluminum or composite material. We have
not changed this AD in this regard.
Request To Add a Note to the Supplemental NPRM
NWA also requested that a note be added to the supplemental NPRM
stating that Parts 1 and 6 of the Accomplishment Instructions of Boeing
Special Attention Service Bulletin 757-32-0176, Revision 1, dated
October 16, 2008, are for operator use and
[[Page 1981]]
compliance documentation is not required.
NWA stated that the FAA did not address its concern in a previous
comment on the original NPRM. NWA stated that the FAA was clear on how
operators perform access and restoration per the operators' normal
maintenance, but the FAA may have missed the point that operators also
have to retain technician sign-off of ADs as permanent records. NWA
stated that if operators access and restore the area via other ``normal
maintenance routine work cards,'' the operators do not desire to
maintain those other work cards just to comply with the retention of
records aspect of rulemaking policy. NWA stated that the access and
restoration are not part of the service instruction safety aspect that
the FAA is trying to mitigate with this rulemaking. NWA stated that by
placing a note in the AD that states that access/restoration is not
part of the safety aspect of the rulemaking and that retention of
records is not required for access/restoration, operators would be
permitted to not have separate access/restoration work cards.
We partially agree with the commenter's request to delete Parts 1
and 6 (access and close). As we clarified in the supplemental NPRM,
Note 8 under paragraph 3.A. of the Accomplishment Instructions of
Boeing Special Attention Service Bulletin 757-32-0176, Revision 1,
dated October 16, 2008, gives provisions for operators to use accepted
alternative procedures for actions specified in the Accomplishment
Instructions when the words ``refer to'' are used. Those words are used
in both Parts 1 and 6 of the Accomplishment Instructions of Boeing
Special Attention Service Bulletin 757-32-0176, Revision 1, dated
October 16, 2008. In addition, although these actions are necessary to
accomplish the inspections, Boeing Special Attention Service Bulletin
757-32-0176, Revision 1, dated October 16, 2008, provides alternative
methods for access and close-up, as defined in Notes 5 and 6 under
paragraph 3.A. of the Accomplishment Instructions of Boeing Special
Attention Service Bulletin 757-32-0176, Revision 1, dated October 16,
2008. Since the suggested note is already contained in the
Accomplishment Instructions of the service bulletin, no additional
notes are necessary in this AD.
We have changed paragraph (g) of this AD to limit the required
actions to those specified only in Parts 2 through 5 of Boeing Special
Attention Service Bulletin 757-32-0176, Revision 1, dated October 16,
2008.
Request To Revise the Initial Compliance Time
One commenter, Jennifer Owens, requested that we revise the initial
compliance time. The commenter stated that the issue of cracked and
broken aluminum springs has been known to the FAA since at least
September 2007 (when the original Boeing ``paperwork''--i.e., service
information--was released). The commenter stated that under the
original docket, published in March 2008, multiple parties requested
that the rule be amended to refer to a later revision of ``the Boeing
paperwork.'' The commenter stated that this later revision of the
``paperwork,'' according to the current proposed rule, was released on
October 16, 2008. The commenter also stated that the new proposed rule
was published on October 19, 2009, just over a year since Boeing
revised its ``paperwork.''
The commenter suggested that the annual utilization rate of about
1,050 flight cycles is representative of how many Model 757 airplanes
are used. The commenter stated that given this delay, and based on this
utilization, operators have had the opportunity to skip three or four
of the required 300-cycle inspections and are approaching the point
where they may skip the first of the 1,500-cycle inspections. The
commenter stated that because of this delay, and the fact that the FAA
chose instead to re-open the comment period, it further delayed the
release of the final rule by another 18 months. The commenter stated
that if a delay of approximately 3 years is acceptable, then the
inspection intervals of approximately 2-3 months and 18 months (based
on the utilization contained above) are unnecessarily short. The
commenter stated that if neither is true, then initial compliance times
should be shortened to account for the delay in releasing the final
rule.
We assume the commenter is referring to Boeing Special Attention
Service Bulletin, 757-32-0176, dated September 10, 2007, as ``the
original Boeing paperwork,'' and Boeing Special Attention Service
Bulletin 757-32-0176, Revision 1, dated October 16, 2008, as ``the
later revision of the Boeing paperwork.'' We disagree with the
commenter's request to revise the initial compliance time. We have
determined that having a terminating modification for the required
inspections provides a higher level of safety than the reliance on
continued re-inspection. Also, in developing an appropriate compliance
time for this action, we considered the safety implications, parts
availability, and normal maintenance schedules for the timely
accomplishment of the modification. We have determined that the
compliance time as proposed will ensure an acceptable level of safety
and allow the modifications to be done during scheduled maintenance
intervals for most affected operators. We have not changed this AD in
this regard.
Explanation of Change Made to This AD
We have revised this AD to identify the legal name of the
manufacturer as published in the most recent type certificate data
sheet for the affected airplane models.
Conclusion
We have carefully reviewed the available data, including the
comments received, and determined that air safety and the public
interest require adopting the AD with the changes described previously.
We have determined that these changes will neither increase the
economic burden on any operator nor increase the scope of the AD.
Explanation of Changes To Costs of Compliance
Since issuance of the NPRM, we have increased the labor rate used
in the Costs of Compliance from $80 per work-hour to $85 per work-hour.
The Costs of Compliance information, below, reflects this increase in
the specified hourly labor rate.
Costs of Compliance
We estimate that this AD would affect 668 airplanes of U.S.
registry. We also estimate that it would take about 1 work-hour per
product to comply with this AD. The average labor rate is $85 per work-
hour. Based on these figures, we estimate the cost of this proposed AD
for U.S. operators to be $56,780, or $85 per product.
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
[[Page 1982]]
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
We have determined that 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); and
(3) 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.
