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:

### 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
