14 CFR Part 39

[Docket No. FAA-2005-22103; Directorate Identifier 2005-CE-42-AD;
Amendment 39-14766; AD 2006-19-09]
RIN 2120-AA64

Airworthiness Directives; Raytheon Aircraft Company Model B300
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Raytheon Aircraft Company (RAC) Model B300 airplanes. This AD requires
you to modify the cabin passenger seats by installing a modification
kit on each passenger seat, removing the existing technical standard
order (TSO) label, and re-identifying each modified passenger seat
assembly with a new part number. This AD results from the seats not
meeting the ultimate load requirements of 14 CFR part 23 during
structural testing of the seat with design changes. We are issuing this
AD to prevent the passenger seats from failing during emergency landing
conditions when high inertial loadings occur. Passenger seat failure
may result in occupant injury.

DATES: This AD becomes effective on October 24, 2006.
As of October 24, 2006, the Director of the Federal Register
approved the incorporation by reference of certain publications listed
in the regulation.

SUPPLEMENTARY INFORMATION:

Discussion

On May 15, 2006, we issued a proposal to amend part 39 of the
Federal Aviation Regulations (14 CFR part 39) to include an AD that
would apply to certain RAC Model B300 airplanes. This proposal was
published in the Federal Register as a notice of proposed rulemaking
(NPRM) on May 19, 2006 (71 FR 29090). The NPRM proposed to require you
to modify the cabin passenger seats by installing a modification kit on
each passenger seat, removing the existing TSO label, and re-
identifying each modified passenger seat assembly with a new part
number.

Comments

We provided the public the opportunity to participate in developing
this AD. We received no comments on the proposal or on the
determination of the cost to the public.

Conclusion

We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed
except for minor editorial corrections. We have determined that these
minor corrections:
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.

Costs of Compliance

We estimate that this AD affects 292 airplanes in the U.S.
registry.
We estimate the following costs to do the modification:

----------------------------------------------------------------------------------------------------------------
Total cost
Parts cost per
Labor cost (per seat) airplane Total cost on U.S. operators
(per seat)
----------------------------------------------------------------------------------------------------------------
3 work-hours (per seat) x $80 per hour = $240. $1,500 $1,740 $2,387,280. The number of passenger
seats per airplane may vary. We
estimate a total of 1,372 seats in
the entire fleet.
----------------------------------------------------------------------------------------------------------------

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 AD.

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:
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); 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 summary of the costs to comply with this AD (and
other information as included in the Regulatory Evaluation) and placed
it in the AD Docket. You may get a copy of this summary by sending a
request to us at the address listed under ADDRESSES. Include ``Docket
No. FAA-2005-22103; Directorate Identifier 2005-CE-42-AD'' in your
request.
