E9-22640. Airworthiness Directives; Vulcanair S.p.A. Models P 68, P 68B, P 68C, P 68C-TC, and P 68 “OBSERVER” Airplanes
-
Start Preamble
AGENCY:
Federal Aviation Administration (FAA), Department of Transportation (DOT).
ACTION:
Notice of proposed rulemaking (NPRM).
SUMMARY:
We propose to supersede Airworthiness Directive (AD) 85-08-04, which applies to certain Vulcanair S.p.A. (Vulcanair) 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 proposed 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 proposing 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:
We must receive comments on this proposed AD by November 5, 2009.

Discussion
Reports of cracks in the front and rear wing spar on Vulcanair P 68 series airplanes caused us to issue AD 85-08-04, Amendment 39-5037 (50 FR 14370, April 12, 1985). AD 85-08-04 currently requires the following on certain Vulcanair Models P 68, P 68B, P 68C, P 68C-TC, and P 68 “OBSERVER” airplanes:
- Repetitively visually inspecting the front and rear wing spars;
- Repairing the front and rear wing spars if cracks are found; andStart Printed Page 48017
- Modifying the front and rear spar if cracks are found or as a terminating action to the repetitive inspections.
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.
This condition, if not corrected, could result in the wing separating from the airplane. This failure could lead to loss of control.
Relevant Service Information
We have reviewed Partenavia Costruzioni Aeronautiche S.p.A. Service Bulletin No. 65 Rev. 3, dated September 30, 1985.
The service information describes procedures for:
- Inspecting the front and rear wing spars for cracks;
- Repairing the front and rear spars if cracks are found; and
- Installing a front and rear spar modification kit.
FAA's Determination and Requirements of the Proposed AD
We are proposing this AD because we evaluated all information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. This proposed AD would supersede AD 85-08-04 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. This proposed AD would require you to use the service information described previously to perform these actions.
Costs of Compliance
We estimate that this proposed AD would affect 81 airplanes in the U.S. registry.
We estimate the following costs to do the proposed inspection:
Labor cost Parts cost Total cost per airplane Total cost on U.S. operators 24 work-hours × $80 per hour = $1,920 Not 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 cost Parts cost Total 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 rulemaking action.
Regulatory Findings
We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 the proposed regulation:
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 regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket that contains the proposed AD, the regulatory evaluation, any comments received, and other information on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Office (telephone (800) 647-5527) is located at the street address stated in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.
