SUPPLEMENTARY INFORMATION:

Discussion

On August 10, 2010, a Piper PA32R-301 airplane crashed after reporting a loss of engine power. The subsequent investigation by the

National Transportation Safety Board suspects a faulty fuel servo,

Bendix model RSA-10ED1. AVStar Fuel Systems (AFS) had overhauled the fuel servo using a new AFS diaphragm, part number (P/N) AV2541803. The diaphragm failed after 19 flight hours (FH) since new due to suspected manufacturing defects. AVStar Fuel Systems produces diaphragms, P/Ns

AV2541801 and AV2541803 under a parts manufacturing authorization

(PMA). Diaphragms produced from specific lot numbers could have stud threads that don't meet design, incomplete braze between the stud and hub, and studs made from lower temper material. Diaphragms from these lots could fail in fatigue prematurely. About 261 diaphragms, P/Ns

AV2541801 and AV2541803, might still be service inside either AFS new or overhauled servos of any manufacturer (Bendix or Precision). Other overhaul facilities may also have purchased AFS diaphragms between the dates of May 21, 2010, and October 19, 2010, and used these diaphragms in their overhauls. This condition, if not corrected, could result in an in-flight engine shutdown due to a failed fuel servo diaphragm and damage to the airplane.

Relevant Service Information

We reviewed AFS Mandatory Service Bulletin (MSB) AFS-SB6, Revision 2, dated April 6, 2011. The MSB provides P/Ns and serial numbers (S/Ns) of affected servos.

FAA's Determination

We are issuing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.

AD Requirements

This AD requires, within 5 FH after the effective date of this AD, removing your fuel servo if AFS Diaphragm P/N AV2541801 or AV2541803 was installed at any time after May 20, 2010, as specified in AFS MSB

AFS-SB6, Revision 2, dated April 6, 2011.

Differences Between the AD and the Service Information

AVStar Fuel Systems MSB AFS-SB6, Revision 2, dated April 6, 2011, doesn't specify a compliance time and recommends limiting special flight permits to delivery to a service location. This AD requires performing the required actions within 5 FH and prohibits special flight permits.

FAA's Justification and Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because of the compliance requirement of 5 FH. Therefore, we find that notice and opportunity for prior

Page 45656

public comment are impracticable and that good cause exists for making this amendment effective in less than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number FAA-2011-0547 and

Directorate Identifier 2011-NE-13-AD at the beginning of your comments.

We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments.

We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.

Costs of Compliance

We estimate that this AD affects 60,000 engines installed on aircraft of U.S. registry. We also estimate that it will take about 0.5 work-hour per engine to perform the inspection, 2.0 work-hours per engine to remove the servo from 261 engines with discrepant AFS

Diaphragm P/N AV2541801 or AV2541803 installed and that the average labor rate is $85 per work-hour. We estimate the parts cost to be $565 per servo. Based on these figures, we estimate the total cost of the AD to U.S. operators to be $2,736,735.

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),

(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.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
