14 CFR Part 39

[Docket No. FAA-2008-1214; Directorate Identifier 2007-NM-259-AD;

Airworthiness Directives; BAE Systems (Operations) Limited 
(Jetstream) Model 4101 Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD), which applies to all BAE Systems (Operations) Limited (Jetstream) 
Model 4101 airplanes. That AD currently requires operators to determine 
the number of flight cycles accumulated on each component of the main 
landing gear (MLG) and the nose landing gear (NLG), and to replace each 
component that reaches its life limit with a serviceable component. The 
existing AD also requires operators to revise the Airworthiness 
Limitations (AWL) section of the Instructions for Continued 
Airworthiness (ICA) in the aircraft maintenance manual to reflect the 
new life limits for structurally significant items. This new AD 
requires a new revision of the AWL section of the ICA to incorporate 
revised life limits for structurally significant items,

[[Page 21247]]

operational and functional tests of certain systems, and instructions 
to retain critical ignition source prevention features during 
configuration changes. This AD results from mandatory continuing 
airworthiness information (MCAI) originated by an aviation authority of 
another country. We are issuing this AD to prevent failure of certain 
structurally significant items, including the MLG and the NLG, which 
could result in reduced structural integrity of the airplane; and to 
prevent fuel vapor ignition sources, which could result in fuel tank 
explosion and consequent loss of the airplane.

DATES: This AD becomes effective June 11, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of June 11, 
2009.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications as of October 26, 2005 (70 FR 
55230, September 21, 2005).

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that supersedes AD 2005-19-15, amendment 
39-14280 (70 FR 55230, September 21, 2005). The existing AD applies to 
all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. 
That NPRM was published in the Federal Register on November 17, 2008 
(73 FR 67817). That NPRM proposed to continue to require operators to 
determine the number of flight cycles accumulated on each component of 
the main landing gear and the nose landing gear, and to replace each 
component that reaches its life limit with a serviceable component. 
That NPRM also proposed to continue to require operators to revise the 
Airworthiness Limitations (AWL) section of the Instructions for 
Continued Airworthiness (ICA) in the aircraft maintenance manual to 
reflect the new life limits for structurally significant items. That 
NPRM also proposed to require a new revision of the AWL section of the 
ICA to incorporate revised life limits for structurally significant 
items, operational and functional tests of certain systems, and 
instructions to retain critical ignition source prevention features 
during configuration changes.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been received on the NPRM 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.

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
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:
    (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); 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 regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
