Start Preamble

AGENCY:

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

ACTION:

Final rule.

SUMMARY:

We are adopting a new airworthiness directive (AD) to supersede AD 85-08-04, which applies to certain Vulcanair S.p.A. Models P 68, P 68B, P 68C, P 68C-TC, and P 68 “OBSERVER” airplanes. AD 85-08-04 currently requires you to repetitively visually inspect the front and rear wing spars for cracks. If cracks are found, AD 85-08-04 requires you to modify the wing spars. The wing spar modification terminates the repetitive inspection AD action and may be installed before cracks develop. Since we issued AD 85-08-04, the manufacturer revised the modification kit and identified additional airplane serial numbers that require the inspection and/or modification. Consequently, this AD would retain the actions of AD 85-08-04, allow you to install the revised modification kit, and add additional serial numbers to the Applicability section. We are issuing this AD to detect and correct cracks in the front and rear wing spar, which could result in the wing separating from the airplane. This failure could lead to loss of control.

DATES:

This AD becomes effective on January 4, 2010.

On January 4, 2010, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD.

Discussion

On September 15, 2009, 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 Vulcanair S.p.A. Models P 68, P 68B, P 68C, P 68C-TC, and P 68 “OBSERVER” airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on September 21, 2009 (74 FR 48016). The NPRM proposed to supersede AD 85-08-04 (50 FR 14370, April 12, 1985) with a new AD that would retain the actions of AD 85-08-04, allow you to install the revised modification kit, and add additional serial numbers to the Applicability section.

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 81 airplanes in the U.S. registry.

We estimate the following costs to do the inspection:Start Printed Page 62212

Labor costParts costTotal cost per airplaneTotal cost on U.S. operators
24 work-hours × $80 per hour = $1,920Not applicable$1,920$155,520

We estimate the following costs to do any necessary repair and modification that would be required based on the results of the proposed inspection. We have no way of determining the number of airplanes that may need this repair/replacement:

Labor costParts costTotal cost per airplane
100 work-hours × $80 per hour = $8,000$700$8,700

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-2009-0869; Directorate Identifier 2009-CE-043-AD” in your request.
