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 


emcdonald on DSK2BSOYB1PROD with RULES
45656 Federal Register / Vol. 76, No. 147 / Monday, August 1, 2011 / Rules and Regulations 

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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD requires 

inspecting the wings for internal and 

external damage, repairing any damage, 

reinforcing the wings, installing 

operational limitation placards in the 

cockpit, and adding limitations to the 

airplane flight manual supplement. This 

AD was prompted by a review of 

installed Flint Aero, Inc. wing tip 

auxiliary fuel tanks, Supplemental Type 

Certificate (STC) SA5090NM. We are 

issuing this AD to detect and correct 

damage in the wings and to prevent 

overload failure of the wing due to the 

installation of the STC. Damage in the 

wing or overload failure of the wing 

could result in structural failure of the 

wing, which could result in loss of 

control. 

DATES: This AD is effective September 6, 

2011.
