14 CFR Part 39
[Docket No. FAA-2010-1043; Directorate Identifier 2010-NM-200-AD;
Amendment 39-16593; AD 2011-03-09]
RIN 2120-AA64
Airworthiness Directives; The Boeing Company Model MD-90-30
Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD requires installing new fire handle
shutoff system wiring. This AD was prompted by a possible latent
failure in the fire handle shutoff relay circuit due to a lack of
separation between engine wires. We are issuing this AD to minimize the
possibility of a multiple engine shutdown due to single fire handle
activation.
DATES: This AD is effective March 14, 2011.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of March 14,
2011.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an airworthiness directive (AD) that would apply to
the specified products. That NPRM published in the Federal Register on
November 5, 2010 (75 FR 68245). That NPRM proposed to require
installing new fire handle shutoff system wiring.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Explanation of Change Made to the 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 reviewed the relevant data and determined that air safety and
the public interest require adopting the AD with the change described
previously. We also determined that this change will not increase the
economic burden on any operator or increase the scope of the AD.
Costs of Compliance
We estimate that this AD will affect 25 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Wiring change.................... 8 work-hours x $85 $489 $1,169 $29,225
per hour = $680.
----------------------------------------------------------------------------------------------------------------
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
[[Page 6536]]
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.
