SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Piper Aircraft, Inc. Models PA–46–310P, 

PA–46–350P, PA–46R–350T, and PA– 

46–500TP airplanes. This AD requires 

inspecting the fuel vent valves to 

identify if the nitrile parts are installed 

and modifying and eventually replacing 

the fuel vent valves if the nitrile parts 

are installed. This AD was prompted by 

nitrile fuel vent valves not providing the 

correct ventilation. If not corrected, this 

unsafe condition may lead to structural 

damage of the wings, which could result 

in loss of control. We are issuing this 

AD to correct the unsafe condition on 

these products.

SUPPLEMENTARY INFORMATION: 

Discussion 

We were notified by Piper Aircraft, 

Inc. that during a demonstration 

emergency descent from 27,000 feet to 

14,000 feet there was an incident on a 

Model PA–46 airplane. The fuel vent 

valve of the main fuel tank assembly did 

not provide proper ventilation, which 

resulted in structural damage to the 

wing. 

The material used to manufacture the 

fuel vent valve was changed from 

fluorosilicone to nitrile, which affected 

the fuel vent valve’s ability to vent 

atmospheric pressure to the main wing 

fuel tank during the rapid descent. The 

nitrile-made part did not allow enough 

air to flow through it because the stiffer 

nitrile-made part did not expand and 

open as large as the fluorosilicone-made 

part under the same pressure and 

temperature conditions. 

Also, in combination with the 

temperature and pressure changes, the 

airplane had a low fuel condition, 

which increased the loading upon the 

main wing that caused the wing skin 

and underlying wing structure to 

buckle. 

This condition, if not corrected, may 

lead to structural damage of the wings, 

which could result in loss of control. 

Relevant Service Information 

We reviewed Piper Aircraft, Inc. 

Mandatory Service Bulletin No. 1258, 

dated June 5, 2013. The service bulletin 

describes procedures for inspecting the 

fuel vent valves to identify if the nitrile 

parts are installed and modifying and 

eventually replacing the fuel vent valves 

if the nitrile parts are installed. 

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 accomplishing the 

actions specified in the service 

information described previously. 

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 nitrile fuel vent valves do 

not provide correct ventilation and may 

lead to structural damage of the wings, 

which could result in loss of control. 

Therefore, we find that notice and 

opportunity for prior 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–2013–0535 and Directorate 

Identifier 2013–CE–018–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 1,379 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspection to identify installation of nitrile 

fuel vent valves.

.5 work-hour × $85 per hour = $42.50 ..... Not applicable ........... $42.50 $58,607.50 

We estimate the following costs to do 

any necessary modifications and 

replacements that would be required 

based on the results of the inspection. 

We have no way of determining the 

number of aircraft that might need these 

modifications and replacements:

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.

DEPARTMENT OF TRANSPORTATION 

Federal Aviation Administration 

14 CFR Part 39 

[Docket No. FAA–2012–1039; Directorate 

Identifier 2011–NM–275–AD; Amendment 

39–17491; AD 2013–13–03] 

RIN 2120–AA64 

Airworthiness Directives; Airbus 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Airbus Model A319–112, –113, and 

–132 airplanes; Model A320–211, –212, 

–214, –231, and –232 airplanes; and 

Model A321–111 and –131 airplanes. 

This AD was prompted by a report of 

two fatigue cracks on the left-hand and 

right-hand sides of the continuity 

fittings at the front windshield lower 

framing on a Model A319 series 

airplane. This AD requires a high 

frequency eddy current (HFEC) 

inspection for any cracking on the lefthand and right-hand sides of the 

windshield central lower node 

continuity fittings, and repair if 

necessary. We are issuing this AD to 

detect and correct cracking of the 

windshield central lower node 

continuity fittings, which could reduce 

the structural integrity of the airplane. 

DATES: This AD becomes effective 

August 14, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of August 14, 2013. 

ADDRESSES: You may examine the AD 

docket on the Internet at http://
