14 CFR Part 39

[Docket No. FAA-2009-0133; Directorate Identifier 2008-NM-107-AD; 
Amendment 39-15933; AD 2009-12-10]

Airworthiness Directives; BAE Systems (Operations) Limited Model 
BAe 146 and Avro 146-RJ 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 Model BAe 
146 and Avro 146-RJ airplanes. That AD currently requires repetitive 
inspections for corrosion of frames 15, 18, 41, and 43 and applicable 
related investigative and corrective actions. The existing AD also 
provides an optional action that would extend the repetitive inspection 
interval. This new AD also requires a high frequency eddy current 
inspection for corrosion of the outer frame flanges and door hinge 
bosses of frames 15, 18, 41, and 43. This AD results from a report 
indicating that corrosion has been detected in the outer frame flanges 
and door hinge bosses during scheduled maintenance. We are issuing this 
AD to prevent reduced structural integrity of the airplane.

DATES: This AD becomes effective July 24, 2009.
    The Director of the Federal Register approved the incorporation by 
reference

of a certain publication listed in the AD as of July 24, 2009.

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 2006-12-09, amendment 
39-14634 (71 FR 33602, June 12, 2006). The existing AD applies to all 
BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ 
airplanes. That NPRM was published in the Federal Register on February 
18, 2009 (74 FR 7565). That NPRM proposed to continue to require 
repetitive inspections for corrosion of frames 15, 18, 41, and 43 and 
applicable related investigative and corrective actions. The NPRM also 
proposed to continue to provide an optional action that would extend 
the repetitive inspection interval. In addition, the NPRM proposed to 
require a high frequency eddy current (HFEC) inspection for corrosion 
of the outer frame flanges and door hinge bosses of frames 15, 18, 41, 
and 43.

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.
