14 CFR Part 39
[Docket No. FAA-2011-0725; Directorate Identifier 2011-NM-065-AD;
Amendment 39-16943; AD 2012-03-02]
RIN 2120-AA64
Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
The Boeing Company Model 767-200, -300, and -300F series airplanes.
This AD was prompted by reports of loss of avionics cooling due to an
unserviceable relay installed on a panel as part of the cabin air
conditioning and temperature control system (CACTCS). This AD requires
doing certain wiring changes, installing a new relay and necessary
wiring in the CACTCS, and performing an operational test of the cooling
pack system. We are issuing this AD to prevent loss of electrical
equipment bay cooling and the overheating of flight deck instruments,
which would result in the eventual loss of primary flight displays, an
unusually high pilot workload, and depressurization of the cabin.
DATES: This AD is effective March 23, 2012.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of March 23,
2012.

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 August 24, 2011 (76 FR
52899). That NPRM proposed to require doing certain wiring changes,
installing a new relay and necessary wiring in the CACTCS, and
performing an operational test of the cooling pack system.
Comments
We gave the public the opportunity to participate in developing
this AD. We have considered the comments received. Boeing supports the
NPRM (76 FR 52899, August 24, 2011). American Airlines stated that it
is not affected by the NPRM.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
the AD as proposed except for minor editorial changes. We have
determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (76 FR 52899, August 24, 2011) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (76 FR 52899, August 24, 2011).
Costs of Compliance
We estimate that this AD affects 35 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
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 the 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.
