SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM published in the Federal Register on October 26, 2011 (76 FR
66200). That NPRM proposed to require inspecting for discrepancies and
insufficient coverage of the secondary fuel barrier, determining the
thickness of the secondary fuel barrier, and corrective actions if
necessary.
Actions Since NPRM (76 FR 66200, October 26, 2011) Was Issued
The NPRM (76 FR 66200, October 26, 2011) referred to Boeing Service
Bulletin 757-57-0060, Revision 2, dated May 24, 2007; and Boeing
Service Bulletin 757-57-0061, Revision 1, dated May 24, 2007; as the
appropriate sources of service information for accomplishing the
proposed actions.
Since we issued the NPRM (76 FR 66200, October 26, 2011), we have
reviewed Boeing Service Bulletin 757-57-0060, Revision 4, dated
December 7, 2012; and Boeing Service Bulletin 757-57-0061, Revision 3,
dated December 7, 2012. We also reviewed Boeing Service Bulletin 757-
57-0060, Revision 3, dated May 9, 2012; and Boeing Service Bulletin
757-57-0061, Revision 2, dated May 4, 2012. Among other things, these
service bulletins eliminate a reference to the ``upper panel'' from
certain steps of the Accomplishment Instructions. Boeing Service
Bulletin 757-57-0061, Revision 2, dated May 4, 2012, also removed
references to Group 2 airplanes from certain parts of the
Accomplishment Instructions.
This final rule has been revised to reference the latest revisions
of this service information. In addition, the reference to ``upper
panel'' has been removed from paragraph (h) of this AD.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the proposal
(76 FR 66200, October 26, 2011) and the FAA's response to each comment.
Boeing supported the NPRM. FedEx had no technical objections to the
NPRM.
Request To Extend the Compliance Time
American Airlines (AA) requested that we revise the NPRM (76 FR
66200, October 26, 2011) to extend the compliance time specified in
paragraph (g) of the NPRM from 60 months to 72 months to align with the
regular heavy check interval for Model 757 airplanes. AA added that,
based on current findings and the design of the vapor barrier, safety
of flight is not affected by extending the compliance time.
We agree with extending the compliance time to 72 months. The
purpose of the secondary fuel barrier on Model 757 airplanes is to
contain leaks due to fastener failures, primary tank sealant failures,
and/or structural cracking of the center fuel tank. Model 757 airplanes
have not had a history of those failures, thus extending the compliance
time from 60 months to 72 months is acceptable for operators to
accomplish the inspections during a regularly scheduled heavy
maintenance check. We revised paragraphs (g), (h), (i), and (j) of this
AD accordingly.
Request To Provide Credit for Previous Actions
British Airways PLc requested that we revise the NPRM (76 FR 66200,
October 26, 2011) to provide credit for Groups 1, 2, and 3 airplanes
for accomplishing the actions specified in Boeing Service
[[Page 22173]]
Bulletin 757-57-0060, dated January 9, 2003; or Boeing Service Bulletin
757-57-0060, Revision 1, dated April 10, 2003. European Air Transport
Leipzig GmbH/DHL Air Ltd. also requested that the NPRM be amended to
provide credit for previous actions performed using Boeing Service
Bulletin 757-57-0060, Revision 1, dated April 10, 2003. British Airways
PLc indicated that not providing credit for previous actions would
represent an unnecessary cost to the aviation industry that would
provide no safety benefit. Both commenters stated that unless credit is
provided, operators that choose to accomplish the actions proactively
using those earlier revisions of this service bulletin would be
penalized.
We partially agree. We agree to provide credit for the actions for
Model 757-200 airplanes identified as Group 3 airplanes. We have added
paragraph (k)(1) of this AD to provide credit for Group 3 airplanes if
those actions were performed using Boeing Service Bulletin 757-57-0060,
Revision 1, dated April 10, 2003; or Boeing Service Bulletin 757-57-
0060, dated January 9, 2003.
However, we disagree to provide credit for any Model 757-200
airplane group other than Group 3. As discussed in the NPRM (76 FR
66200, October 26, 2011), Boeing Service Bulletin 757-57-0060, Revision
2, dated May 24, 2007, contains further detailed inspection
requirements for the secondary fuel barrier for Model 757-200 airplanes
identified as Group 1 and Group 4, Configuration 1; and for Model 757-
200CB and 757-200PF airplanes identified as Group 2. Boeing Service
Bulletin 757-57-0060, Revision 2, dated May 24, 2007, had additional
requirements that were not included in earlier revisions. These
additional requirements are inspection for air bubbles or blister-like
areas, solid metallic particles, and defective surfaces that are found
in the secondary fuel barrier, not just found between the secondary
fuel barrier and the structure. Also, Boeing Service Bulletin 757-57-
0060, Revision 2, dated May 24, 2007, provides procedures for thickness
measurements for Model 757-200 airplanes identified as Group 4,
Configuration 1; and Group 4, Configuration 2 airplanes.
In addition, we have determined that it is also appropriate to
provide credit for actions done for Model 757-300 airplanes identified
as Group 2 airplanes. We have added paragraph (k)(4) of this AD to
provide credit for Model 757-300 airplanes identified as Group 2
airplanes if those actions were performed using Boeing Service Bulletin
757-57-0061, dated February 6, 2003, before the effective date of this
AD.
Additional Changes Made to This AD
As previously explained, since the NPRM (76 FR 66200, October 26,
2011) was issued, Boeing released Boeing Service Bulletin 757-57-0060,
Revision 4, dated December 7, 2012; and Boeing Service Bulletin 757-57-
0061, Revision 3, dated December 7, 2012. Therefore, we find it
appropriate to provide credit in paragraph (k) of this final rule for
Boeing Service Bulletin 757-57-0060, Revision 3, dated May 9, 2012;
Boeing Service Bulletin 757-57-0060, Revision 2, dated May 24, 2007;
Boeing Service Bulletin 757-57-0061, Revision 2, dated May 4, 2012; and
Boeing Service Bulletin 757-57-0061, Revision 1, dated May 24, 2007.
Note 1 to paragraph (g) of the NPRM (76 FR 66200, October 26, 2011)
defined a detailed inspection. We have removed that note in this final
rule, since the appropriate service information contains the inspection
definition.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
the AD with the changes described previously--and minor editorial
changes. We have determined that these minor changes:
<bullet> [Agr]re consistent with the intent that was proposed in
the NPRM (76 FR 66200, October 26, 2011) for correcting the unsafe
condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (76 FR 66200, October 26, 2011).
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of the AD.
Costs of Compliance
We estimate that this AD affects 619 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor Cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Access and inspect secondary fuel 42 work-hours x $85 per $0 $3,570 $2,209,830
barrier. hour = $3,570 per
inspection.
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary repairs that
would be required based on the results of the inspection. We have no
way of determining the number of aircraft that might need these
repairs:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
-------------------------------------------------------------------------------------------------
Apply secondary fuel barrier......... 7 work-hours x $85 per $0 $595
hour = $595 per
secondary fuel barrier
application.
----------------------------------------------------------------------------------------------------------------
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.
[[Page 22174]]
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.
