ACTION:

Final rule.

SUMMARY:

We are adopting a new airworthiness directive (AD) for all 328 Support Services GmbH (Type Certificate previously held by AvCraft Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) Model 328-100 and 328-300 airplanes. This AD was prompted by a manufacturer safety analyses review on flight control which resulted in recommendations for reduced repetitive inspection intervals for the flight controls certification maintenance requirements (CMR) of the tab-to-actuator linkage. This AD requires revising the airplane maintenance program by incorporating certain CMR tasks. We are issuing this AD to prevent failure of these components or their constituent parts which could lead to reduced control of the airplane.

DATES:

This AD becomes effective February 29, 2012.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of February 29, 2012.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on October 5, 2011 (76 FR 61638). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

Based on in-service experience, the System Safety Analyses for the Flight Controls have been reviewed and their conclusions have been accepted during the latest Candidate Maintenance Coordination Committee meeting.

This review resulted in reduced inspection intervals, specifically for the flight controls tab-to-actuator linkage CMR repetitive inspections, which have been identified as mandatory actions for continued airworthiness.

Failure of these components or their constituent parts could lead to reduced control of the aeroplane.

Consistent with the [European Aviation Safety Agency] EASA policy to require compliance with any new and reduced airworthiness limitations by taking AD action and for the reasons described above, this EASA AD requires the accomplishment of the reduced-interval repetitive inspections and, depending on findings, related corrective action(s). In addition, this [EASA] AD requires the implementation of the affected reduced inspection intervals and associated corrective actions into the operator's approved maintenance programme.

You may obtain further information by examining the MCAI in the AD docket.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (76 FR 61638, October 5, 2011) or on the determination of the cost to the public.

Conclusion

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

  • Are consistent with the intent that was proposed in the NPRM (76 FR 61638, October 5, 2011) for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM (76 FR 61638, October 5, 2011).

Costs of Compliance

We estimate that this AD will affect 63 products of U.S. registry. We also estimate that it will take about 1 work-hour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $5,355, or $85 per product.

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 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 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 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. We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

Examining the AD Docket

You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM (76 FR 61638, October 5, 2011), the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647-5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.
