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.
