Federal Register Abstract
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 767-200, -300, and -300F series airplanes. That AD currently requires repetitive inspections of the lubrication passage and link assembly joint in the inboard and outboard flaps of the trailing edge for discrepancies, and corrective action if necessary. This new AD requires new inspections for cracking or severe wear of the bearings of the link assembly, inspections of any link assembly not previously inspected for damage, and corrective actions if necessary. This AD also ends the existing repetitive inspections for certain airplanes, and extends the repetitive interval for the existing repetitive inspections and the compliance time for the corrective action on certain other airplanes. This AD also provides an optional terminating action. This AD results from additional reports indicating fractured bearings of the link assembly joint in the inboard and outboard flaps of the trailing edge. We are issuing this AD to prevent failure of the bearings in the link assembly joint, which could result in separation of the inboard or outboard flap and consequent loss of control of the airplane.

Airworthiness Directives; Boeing Model 767-200, -300, and -300F
Series Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD), which applies to certain Boeing Model 767-200, -300, and -300F
series airplanes. That AD currently requires repetitive inspections of
the lubrication passage and link assembly joint in the inboard and
outboard flaps of the trailing edge for discrepancies, and corrective
action if necessary. This new AD requires new inspections for cracking
or severe wear of the bearings of the link assembly, inspections of any
link assembly not previously inspected for damage, and corrective
actions if necessary. This AD also ends the existing repetitive
inspections for certain airplanes, and extends the repetitive interval
for the existing repetitive inspections and the compliance time for the
corrective action on certain other airplanes. This AD also provides an
optional terminating action. This AD results from additional reports
indicating fractured bearings of the link assembly joint in the inboard
and outboard flaps of the trailing edge. We are issuing this AD to
prevent failure of the bearings in the link assembly joint, which could
result in separation of the inboard or outboard flap and consequent
loss of control of the airplane.
DATES: This AD becomes effective June 19, 2006.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of June 19, 2006.
On February 14, 2002 (67 FR 4328, January 30, 2002), the Director
of the Federal Register approved the incorporation by reference of
Boeing Alert Service Bulletin 767-27A0167, dated December 7, 2000.

Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that supersedes AD 2002-01-15, amendment
39-12609 (67 FR 4328, January 30, 2002). The existing AD applies to
certain Boeing Model 767-200, -300, and -300F series airplanes. That
NPRM was published in the Federal Register on September 27, 2005 (70 FR
56383). That NPRM proposed to require the following actions:
<bullet> Repetitive inspections of the lubrication passage and link
assembly joint in the inboard and outboard flaps of the trailing edge
for discrepancies, and corrective action if necessary.
<bullet> New inspections for cracking or severe wear of the
bearings of the link assembly, and corrective actions if necessary.
<bullet> Inspections of any link assembly not previously inspected
for damage, and replacement with a new assembly if necessary.
That NPRM also proposed to end the existing repetitive inspections for
certain airplanes, and extend the repetitive interval for the existing
repetitive inspections and the compliance time for the corrective
action on certain other airplanes. That NPRM also provided an optional
terminating action that would end the repetitive inspections.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments that have been
received on the NPRM.
Support for the Proposed AD
One commenter, US Airways, supports the NPRM.
Request To Clarify Compliance Times
Boeing requests that we clarify a compliance time stated in
paragraph (g)(2) of the NPRM. For an airplane on which the lubrication
passage was blocked but no fractured bearing or loose or damaged joint
was found, paragraph (g)(2) of the NPRM would require doing the actions
in Part 2 of Boeing Alert Service Bulletin 767-27A0167 within 24 months
after doing the initial inspection in accordance with Part 1 of the
service bulletin. The commenter notes that the relevant point in time
is the most recent inspection in accordance with Part 1 of the service
bulletin, which is not necessarily the time of the initial inspection.
The commenter requests that we revise paragraph (g)(2) to require doing
the actions in Part 2 of the service bulletin within 24 months after
the most recent inspection in accordance with paragraph (a) of AD 2002-
01-15.
We agree with the request and have revised paragraph (g)(2) of this
AD for the reasons that Boeing states. For clarification, we have also
included references to repetitive inspections performed in accordance
with
[[Page 27950]]
paragraph (b)(1) of AD 2002-01-15 and inspections performed in
accordance with paragraph (f) of this AD.
Similarly, Boeing requests that we clarify the compliance time in
paragraph (h) of the NPRM. Paragraph (h) of the NPRM states a
compliance time of ``24 months after the most recent inspection in
accordance with paragraph (b)(1) of AD 2002-01-15.'' The commenter
notes that paragraph (b)(1) of AD 2002-01-15 states only the repetitive
inspection interval. It is possible that the most recent inspection may
have been the initial inspection in accordance with paragraph (a) of AD
2002-01-15.
We agree. We have revised paragraph (h) of this AD to state a
compliance time of ``24 months after the most recent inspection in
accordance with paragraph (a) or (b)(1) of AD 2002-01-15, or paragraph
(f) of this AD, as applicable.''
Request To Clarify Appropriate Source of Service Information
The Air Transport Association (ATA), on behalf of one of its
members, Delta Airlines (Delta), requests that we revise paragraphs (f)
and (g) of the NPRM, which restate paragraphs (a) and (b) of AD 2002-
01-15. The commenter would like us to remove references to Boeing Alert
Service Bulletin 767-27A0167, dated December 7, 2000, in those
paragraphs. Delta feels that the reference to the original issue of the
service bulletin is confusing and should be deleted from paragraphs (f)
and (g) of the NPRM, in light of the fact that these paragraphs state
``After the effective date of this AD, only Revision 2 of the service
bulletin may be used.''
We do not agree. We are restating the requirements of AD 2002-01-
15, including the references to the original issue of Boeing Alert
Service Bulletin 767-27A0167, to ensure that operators who have
previously done required actions in accordance with that service
bulletin are still in compliance with the AD. If we remove the
reference to the original issue of Boeing Alert Service Bulletin 767-
27A0167 and refer to only Revision 2 of that service bulletin, then
operators who previously did the required actions in accordance with
the original issue of the service bulletin would be out of compliance
as of the effective date of the new AD. We find that inspections that
have been done before the effective date of this AD in accordance with
the instructions in the original issue of the service bulletin will
provide an acceptable level of safety until the newly required actions
are done. We have not changed the AD in this regard.
Request To Revise Compliance Time for Restated Actions
Boeing requests that we revise the compliance time for the initial
inspection in paragraph (f) of the NPRM. Paragraph (f) of the NPRM
specifies compliance ``within 90 days after February 14, 2002 (the
effective date of AD 2002-01-15), or within 36 months after date of
manufacture of the airplane, whichever is later.'' The commenter
requests that we change this compliance time to ``within 90 days after
the effective date to this AD, or within 6 months after the most recent
inspection in accordance with paragraph (a) of AD 2002-01-15, whichever
is later.'' The commenter states that airplanes will be out of
compliance upon the effective date of the new AD, even if the
inspections in accordance with Part 1 of Boeing Alert Service Bulletin
767-27A0167 are currently being done.
We do not agree. As explained previously, paragraph (f) of this AD
restates the initial inspection requirements of paragraph (a) of AD
2002-01-15. Our research indicates that inspections in accordance with
paragraph (a) of that AD should have been accomplished on affected
airplanes no later than 2004, considering that the last affected
airplane was manufactured in 2000. We find that any affected airplane
currently on the U.S. Register is already required to be in compliance
with the requirements of paragraph (f) of this AD. Further, because the
compliance time for these requirements has passed, the inspections
required by paragraph (f) of this AD would have to be accomplished on
any airplane that is not currently on the U.S. Register before that
airplane could be added to the Register. We have not changed the AD in
this regard.
Request To Rearrange Paragraphs
ATA, on behalf of UPS, requests that paragraph (g) of the NPRM be
included under the heading ``NEW REQUIREMENTS OF THIS AD,'' and that
paragraph (h) of the NPRM be restated as paragraph (g)(1). UPS states
that the requirements of paragraph (g) do not reflect the requirements
of paragraph (b) of AD 2002-01-15.
We acknowledge that paragraph (g) of this AD is different than
paragraph (b) of AD 2002-01-15. Compliance times for certain actions
specified in paragraph (g) have been extended beyond the compliance
times that are currently required by paragraph (b) of AD 2002-01-15.
Also, the repetitive inspection requirement has been removed for
airplanes on which no discrepancy was found during the initial
inspection. However, we consider paragraph (g) of this AD to be a
restatement of the requirements of paragraph (b) of AD 2002-01-15
because the actions remaining in paragraph (g) are essentially the same
as those in paragraph (b), and the changes to the compliance times are
relieving, giving affected operators more time to comply with the
existing requirements or obviating the need to continue repetitive
inspections. We have revised the heading that precedes paragraph (g) of
this AD to acknowledge that we have changed the compliance times in
that paragraph from the times specified in AD 2002-01-15. We find that
no further change to the AD is necessary in this regard.
Request To Extend Compliance Times
ATA, on behalf of UPS, requests that we extend the compliance time
for doing Part 2 of the service bulletin from 24 months after the
initial or most recent inspection in accordance with AD 2002-01-15, as
applicable (as stated in paragraphs (g)(2) and (h) of the NPRM), to 24
months after the effective date of the new proposed AD. The commenter
states that this change would ensure an acceptable level of safety and
alleviate potential scheduling burdens. The commenter did not provide
data supporting its position.
We do not agree. The compliance time of 24 months since the most
recent inspection in accordance with AD 2002-01-15 is based on service
history of bearing failure, as well as recommendations by the
manufacturer based on extensive testing. We measure the compliance time
from the most recent inspection to preserve the existing inspections
and prevent a lapse in maintenance. This compliance time represents the
maximum compliance time allowable to adequately ensure safety. Revising
the compliance time to 24 months after the effective date of the AD may
inadvertently extend the compliance time by as long as 18 months. We
find that this would not adequately ensure safety. We have not changed
the AD in this regard.
Request To Allow Continued Repetitive Inspections Until Extended
Compliance Time
ATA, on behalf of UPS, requests that we allow repetitive
inspections in accordance with Part 1 of the service bulletin to
continue at the 6-month interval specified in paragraph (b) of AD 2002-
01-15, until Parts 2 and 3 of the service bulletin are done. (This
request is related to the same commenter's request, discussed
previously, to extend
[[Page 27951]]
the compliance time for Part 2 to 24 months after the effective date of
this AD.) The commenter states that allowing repetitive inspections to
continue would ensure an acceptable level of safety.
We do not agree. As we explained in the preamble of the NPRM, there
have been numerous additional findings of fractured bearings of the
link assembly joint since we issued AD 2002-01-15. These findings
occurred during accomplishment of Part 2 of the service bulletin,
providing evidence that the bearings of the link assembly joint may
fail even when they are properly lubricated, and the inspections in
Part 1 are not adequate to detect fractured bearings. We have not
changed the AD in this regard.
Request To Extend Grace Period for Part 3 of Service Bulletin
ATA, on behalf of UPS, requests that we extend the grace period for
doing Part 3 of the service bulletin from 18 months after the effective
date of the AD (as stated in paragraphs (i)(1) and (i)(2) of the NPRM)
to 24 months after the effective date of the AD. The commenter
indicates that these grace periods would alleviate scheduling burdens
associated with the 18-month compliance time. The commenter provides no
justification for its request.
We do not agree. Though the service bulletin does not provide a
grace period for doing the actions in Part 3 of the service bulletin,
we have included a grace period of 18 months. In establishing this
grace period, we considered the manufacturer's recommendation, typical
operators' maintenance schedules, and the degree of urgency associated
with the subject unsafe condition. We also considered the small number
of airplanes included in Group 2 in the service bulletin. Based on
these factors, we find that the 18-month grace period will not create
scheduling burdens because the actions in Part 3 of the service
bulletin are required at 72 months after accomplishing the Part 2
inspection (for Group 1 airplanes), or 72 months since the date of
issuance of the original standard airworthiness certificate or the date
of issuance of the original export certificate of airworthiness (for
Group 2 airplanes); or 18 months after the effective date of the AD. We
have not changed the AD in this regard.
Request To Clarify Meaning of ``Initial Inspection''
ATA, on behalf of UPS, requests that we revise paragraph (i)(2) of
the NPRM to more specifically define that the ``initial'' inspection
specified for Group 2 airplanes in that paragraph means the inspection
in accordance with Part 3 of Boeing Alert Service Bulletin 767-27A0167,
Revision 2, dated October 7, 2004. We infer that the commenter is
concerned about the potential for misunderstanding the difference
between the ``initial inspection'' specified in paragraph (f) of the
NPRM and the inspection in accordance with Part 3 of the service
bulletin that is specified in paragraph (i) of the NPRM.
We agree with the commenter's request. We have revised the wording
of paragraph (i)(2) to remove the words, ``Do the initial inspection.''
This change results in the wording of paragraph (i)(2) now paralleling
the wording of paragraph (i)(1).
Conclusion
We have carefully reviewed the available data, including the
comments that have been 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.
Costs of Compliance
There are about 855 airplanes of the affected design in the
worldwide fleet. The following table provides the estimated costs for
U.S. operators to comply with this AD, at an average labor rate of $65
per work hour.
Estimated Costs

to this action.
The optional terminating action provided in this AD, if
accomplished, would take about 23 work hours per airplane, at an
average labor rate of $65 per work hour. Required parts would cost
about $3,885 per airplane. Based on these figures, the estimated cost
of the optional terminating action specified in this AD is $5,380 per
airplane.
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
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,
[[Page 27952]]
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.
