ACTION: Final rule. AGENCY: We are superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires an inspection to determine if a certain fuel pump housing electrical connector is installed. The existing AD also requires a revision to the FAA-approved airplane flight manual (AFM) to advise the flightcrew of the appropriate procedures for disabling certain fuel pump electrical circuits following failure of a fuel pump housing electrical connector if applicable. The existing AD also requires the deactivation of certain fuel tanks or fuel pumps and the installation of placards if applicable.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede airworthiness directive (AD) 2007–15–05, amendment 39–15134 (72 FR 40216, July 24, 2007). That AD applies to the specified products. The NPRM published in the Federal Register on November 5, 2010 (75 FR 68246). That NPRM proposed to require replacing the fuel pump housing electrical assembly with a new part and doing repetitive inspections for continuity, resistance, and insulation resistance, and doing corrective actions, if necessary. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal and the FAA’s response to each comment. Request for Addition of Part Number FedEx requested that we add, in the header above the Summary and paragraphs (c), (e), and (f) of the proposed AD, the part number of the fuel pump housing electrical connector assembly requiring replacement. FedEx stated that the change will clarify the AD and avoid unnecessary work and cost to the operators. We partially agree with the commenter. We disagree with adding the part number of the fuel pump housing electrical connector assembly requiring replacement to the header information, paragraph (c), and paragraph (f) of this AD because the affected part could be rotated onto any of the airplanes listed in the applicability. However, we agree that clarification of paragraph (h) of this AD (referred to as paragraph (g) in the NPRM) is needed. In order to comply with this AD, for all airplanes in the applicability it must be determined if the fuel pump housing electrical connector assembly having part number (P/N) 60–84355–1 is installed. We have added paragraph (g) to specify the inspection to determine the part number. We have also added a reference of P/N 60–84355–1 to paragraph (h) of this AD for clarification. In addition, we have added a reference of P/N 60– 84355–1 to paragraph (e) of this AD for clarification. E:\FR\FM\01JNR1.SGM 01JNR1 Federal Register / Vol. 76, No. 105 / Wednesday, June 1, 2011 / Rules and Regulations Clarification of Paragraph (i) of This AD clarify that P/N 60–84351 must be repetitively inspected after installation. We have revised paragraph (i) of this AD by replacing the phrase, ‘‘replacing the fuel pump electrical connector assembly as required by paragraph (g) of this AD’’ with the phrase, ‘‘installing the fuel pump housing electrical connector assembly having P/N 60–84351, in accordance with Boeing Alert Service Bulletin DC10–28A261 or Boeing Alert Service Bulletin MD11–28A143,’’ to Conclusion We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting the AD with the change described previously— and minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and 31463 • Do not add any additional burden upon the public than was already proposed in the NPRM. 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 281 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Work hours Inspection ............... Average labor rate per hour Between 20 and 36 per inspection cycle. Up to 44 ................. Replacement .......... Up to $4,478 .......... Between $1,700 and $3,060 per inspection cycle. Up to $8,218 ..........

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding an existing airworthiness directive (AD)
for the products listed above. That AD currently requires an inspection
to determine if a certain fuel pump housing electrical connector is
installed. The existing AD also requires a revision to the FAA-approved
airplane flight manual (AFM) to advise the flightcrew of the
appropriate procedures for disabling certain fuel pump electrical
circuits following failure of a fuel pump housing electrical connector
if applicable. The existing AD also requires the deactivation of
certain fuel tanks or fuel pumps and the installation of placards if
applicable. The existing AD allows the optional replacement of the fuel
pump housing electrical connectors with new, improved parts, which
would terminate the AFM revisions, deactivation of certain fuel tanks
and fuel pumps, and placard installation. This new AD instead requires
replacing the fuel pump housing electrical connector assembly with a
new part and doing repetitive inspections for continuity, resistance,
and insulation resistance, and doing corrective actions if necessary.
This AD was prompted by reports of failures of a certain fuel pump
housing electrical connector. We are issuing this AD to detect and
correct insulation resistance degradation and arcing in the potted
backside of the electrical connector assembly of the fuel boost/
transfer pump housing, which could compromise its performance and cause
an ignition source in the fuel tank, resulting in a fuel tank explosion
and consequent loss of the airplane.

DATES: This AD is effective July 6, 2011.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of July 6, 2011.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede airworthiness directive (AD) 2007-15-05, amendment
39-15134 (72 FR 40216, July 24, 2007). That AD applies to the specified
products. The NPRM published in the Federal Register on November 5,
2010 (75 FR 68246). That NPRM proposed to require replacing the fuel
pump housing electrical assembly with a new part and doing repetitive
inspections for continuity, resistance, and insulation resistance, and
doing corrective actions, if necessary.

Comments

We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the proposal
and the FAA's response to each comment.

Request for Addition of Part Number

FedEx requested that we add, in the header above the Summary and
paragraphs (c), (e), and (f) of the proposed AD, the part number of the
fuel pump housing electrical connector assembly requiring replacement.
FedEx stated that the change will clarify the AD and avoid unnecessary
work and cost to the operators.
We partially agree with the commenter. We disagree with adding the
part number of the fuel pump housing electrical connector assembly
requiring replacement to the header information, paragraph (c), and
paragraph (f) of this AD because the affected part could be rotated
onto any of the airplanes listed in the applicability. However, we
agree that clarification of paragraph (h) of this AD (referred to as
paragraph (g) in the NPRM) is needed. In order to comply with this AD,
for all airplanes in the applicability it must be determined if the
fuel pump housing electrical connector assembly having part number (P/
N) 60-84355-1 is installed. We have added paragraph (g) to specify the
inspection to determine the part number. We have also added a reference
of P/N 60-84355-1 to paragraph (h) of this AD for clarification. In
addition, we have added a reference of P/N 60-84355-1 to paragraph (e)
of this AD for clarification.

[[Page 31463]]

Clarification of Paragraph (i) of This AD

We have revised paragraph (i) of this AD by replacing the phrase,
``replacing the fuel pump electrical connector assembly as required by
paragraph (g) of this AD'' with the phrase, ``installing the fuel pump
housing electrical connector assembly having P/N 60-84351, in
accordance with Boeing Alert Service Bulletin DC10-28A261 or Boeing
Alert Service Bulletin MD11-28A143,'' to clarify that P/N 60-84351 must
be repetitively inspected after installation.

Conclusion

We reviewed the relevant data, considered the comment received, and
determined that air safety and the public interest require adopting the
AD with the change described previously--and minor editorial changes.
We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
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 281 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

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, or on the distribution of power
and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:

AD performed within the compliance times specified, unless the
actions have already been done.

Inspection and Change

(g) For all airplanes: Within 10 months after the effective date
of this AD, do an inspection of the fuel pump housing electrical
connector to determine if part number (P/N) 60-84355-1 is installed.
A review of airplane maintenance records is acceptable in lieu of
this inspection if the part number of the fuel pump housing
electrical connector can be conclusively determined from that
review.
