02-24179. Airworthiness Directives; Vulcanair S.p.A. P 68 Series Airplanes

AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Final rule.

SUMMARY:

This amendment adopts a new airworthiness directive (AD) that applies to certain Vulcanair S.p.A. (Vulcanair) P 68 series airplanes. This AD requires you to inspect the flight and engine control systems to ensure that there is correct connecting bolt and linkage installation, no interference, and correct installation of certain components. This AD also requires you to make any necessary adjustments and modify and install the split link and full travel limit assembly. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Italy. The actions specified by this AD are intended to prevent failure of the primary flight control system caused by certain configurations. Such failure could lead to loss of airplane flight control.

DATES:

This AD becomes effective on November 8, 2002.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of November 8, 2002.

ADDRESSES:

SUPPLEMENTARY INFORMATION:

Discussion

What Events Have Caused This AD?

The Ente Nazionale per l'Aviazione Civile (ENAC), which is the airworthiness authority for Italy, recently notified FAA that an unsafe condition may exist on certain Vulcanair Models P 68, P 68B, P 68C, P 68C-TC, P 68 “OBSERVER”, AP68TP300 “SPARTACUS”, P68TC “OBSERVER”, AP68TP 600 “VIATOR”, and P68 “OBSERVER 2” airplanes. The ENAC reports several instances of incorrectly installed bolts, missing nuts, and the presence of interference between the forward control lever assembly and the airframe.

What Is the Potential Impact if FAA Took No Action?

If not detected and corrected, these conditions could result in failure of the primary flight controls. Such failure could lead to loss of airplane flight control.

Has FAA Taken Any Action to This Point?

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 P 68 series airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on July 15, 2002 (67 FR 46427). The NPRM proposed to require you to:

—Inspect for interference between the control column interconnection chain and the engine control pedestal assembly when the flight controls are in the maximum nose-down position;

—Inspect to ensure that the split link is correctly installed in the chain and that the lock-wire is present and undamaged;

—Make any necessary adjustments;

—Modify and install the split link and full travel limit assembly;

—Inspect all control cable and control rod connecting bolts and linkages for proper installation;

—Inspect for interference between the flight control components and the airframe installations;

—Make any necessary adjustments; and

—Inspect for the correct installation of the part number AN24-18A bolt that connects the forward control cable rod to the control column and reinstalling if necessary.

Was the Public Invited To Comment?

The FAA encouraged interested persons to participate in the making of this amendment. We did not receive any comments on the proposed rule or on our determination of the cost to the public.

FAA's Determination

What Is FAA's Final Determination on This Issue?

After careful review of all available information related to the subject presented above, we have determined that air safety and the public interest require the adoption of the rule as proposed except for minor editorial corrections. We have determined that these minor corrections:

—Provide 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.

Cost Impact

How Many Airplanes Does This AD Impact?

We estimate that this AD affects 58 airplanes in the U.S. registry. The actions specified in Vulcanair P68 Series Service Bulletin No. 110 affect 15 U.S.-registered airplanes. The actions specified in Vulcanair P68 Series Service Bulletin No. 111, Rev. 1, affect 58 U.S.-registered airplanes.

What Is the Cost Impact of This AD on Owners/Operators of the Affected Airplanes?

We estimate the following costs to accomplish the inspections and modifications of Vulcanair P68 Series Service Bulletin No. 110:

Labor cost	Parts cost	Total cost per airplane	Total cost on U.S. operators
7 workhours × $60 per hour = $420	$150	$570	$8,550

We estimate the following costs to accomplish the inspections of Vulcanair P68 Series Service Bulletin No. 111, Rev. 1:

Labor cost	Parts cost	Total cost per airplane	Total cost on U.S. operators
4 workhours × $60 per hour = $240	None	$240	$13,920

The FAA has no method of determining the number of necessary adjustments each owner/operator will incur if connecting bolts, linkage, etc. were found incorrectly installed. We estimate the cost to be minor.

Compliance Time of This AD

What Will Be the Compliance Time of This AD?

The compliance time of this AD is “within the next 30 days after the effective date of the AD.”

Why Is the Compliance Time Presented in Calendar Time Instead of Hours Time-in-Service (TIS)?

The compliance of this AD is presented in calendar time instead of hours TIS because these missing or incorrectly installed parts is due to a lack of quality control at the factory. The problem has the same chance of existing on an airplane with 50 hours TIS as it would for an airplane with 1,000 hours TIS. Therefore, we believe that 30 days will:

—Ensure that the unsafe condition does not go undetected for a long period of time on the affected airplanes; and

—Not inadvertently ground any of the affected airplanes.

Regulatory Impact

Does This AD Impact Various Entities?

The regulations adopted herein 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. Therefore, it is determined that this final rule does not have federalism implications under Executive Order 13132.

Does This AD Involve a Significant Rule or Regulatory Action?

For the reasons discussed above, I certify that this action (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. A copy of the final evaluation prepared for this action is contained in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.
