Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule.

SUMMARY:

We are adopting a new airworthiness directive (AD) for Maryland Air Industries, Inc., Model Fairchild F-27 and FH-227 Series Airplanes. This AD requires operators to modify their airplanes and revise their inspection or maintenance programs to incorporate instructions for maintenance and inspection of the fuel tank systems, as appropriate, by December 16, 2008, using information developed in accordance with Special Federal Aviation Regulation 88 (SFAR 88). This AD results from fuel system safety reviews done on similar airplane models in accordance with SFAR 88. These safety reviews identified potential unsafe conditions on Model Fairchild F-27 and FH-227 series airplanes for which the type certificate holder, Maryland Air Industries, Inc., has not conducted SFAR 88 safety reviews, has not provided corrective actions, and does not plan to do so. We are issuing this AD to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

DATES:

This AD is effective November 28, 2008.

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 all Maryland Air Industries, Inc., Model Fairchild F-27 and FH-227 series airplanes. That NPRM was published in Start Printed Page 63353the Federal Register on July 21, 2008 (73 FR 42282). That NPRM proposed to require operators to modify their airplanes and revise their inspection or maintenance programs to incorporate instructions for maintenance and inspection of the fuel tank systems, as appropriate, by December 16, 2008, using information developed in accordance with Special Federal Aviation Regulation 88.

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.

Conclusion

We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed.

Costs of Compliance

We estimate that this AD affects 29 airplanes of U.S. registry. We recognize that this AD might impose certain costs. However, we cannot calculate those costs because we cannot anticipate the complexity or content of the plans that operators will submit to the FAA. However, continued operational safety necessitates the imposition of these costs because of the severity of the unsafe condition.

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 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.

You can find our regulatory evaluation and the estimated costs of compliance in the AD Docket.
