Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to supersede airworthiness directive (AD) 2013-14-08 that applies to all Austro Engine GmbH model E4 engines. AD 2013-14-08 requires removing from service certain part number (P/N) waste gate controllers. Since we issued AD 2013-14-08 we received several reports of power loss events due to fracture of the waste gate controller lever. This proposed AD would require removing certain P/N waste gate controllers from service. We are proposing this AD to prevent failure of the waste gate controller lever, which could lead to damage to one or more engines, loss of thrust control, and damage to the airplane.

DATES:

We must receive comments on this proposed AD by March 11, 2014.

ADDRESSES:

You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:

Discussion

On July 10, 2013, we issued AD 2013-14-08, Amendment 39-17513 (78 FR 42677, July 17, 2013), (“AD 2013-14-08”), for all Austro Engine GmbH model E4 engines. AD 2013-14-08 requires removing from service certain P/N waste gate controllers. AD 2013-14-08 resulted from several reports of power loss events due to fracture of the waste gate controller lever. We issued AD 2013-14-08 to prevent failure of the waste gate controller lever, which could lead to damage to one or more engines, loss of thrust control, and damage to the airplane.

Actions Since AD 2013-14-08 Was Issued

Since we issued AD 2013-14-08, we received notification of additional waste gate controller P/Ns that require removal from service. Also since we issued AD 2013-14-08, the European Aviation Safety Agency (EASA) has issued AD 2013-0213, dated September 13, 2013, which requires removal and replacement of affected waste gate controllers. We also changed the unsafe condition statement in AD 2013-14-08 to clarify the relationship between the unsafe condition and the engine.

Relevant Service Information

We reviewed Austro Engine Mandatory Service Bulletin (MSB) No. MSB-E4-007/6, Revision 6, dated September 18, 2013. The service information describes procedures for removal and installation of the waste gate controllers.

FAA's Determination

We are proposing 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.

Proposed AD Requirements

This proposed AD would retain all of the requirements of AD 2013-14-08. This proposed AD would expand the applicability by adding additional P/Ns of affected waste gate controllers.

Costs of Compliance

We estimate that this proposed AD would affect 128 engines installed on airplanes of U.S. registry. We also estimate that it would take about 0.5 hours per engine to comply with this proposed AD. The average labor rate is $85 per hour. Required parts cost about $231 per engine. Based on these figures, we estimate the total cost of this proposed AD to U.S. operators to be $35,008.

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

We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 the proposed regulation:

(1) Is not a “significant regulatory action” under Executive Order 12866,

(2) Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979),

(3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction, 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.
