**Airworthiness Directives; Austro Engine GmbH Engines** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for all Austro Engine GmbH model E4 engines. This proposed AD was prompted by reports of several power loss events due to fracture of the waste gate controller lever. This proposed AD would require removing from service certain part number (P/N) waste gate controllers. We are proposing this AD to prevent engine power loss or in-flight shutdown, which could result in loss of control and damage to the airplane.

**DATES :**  We must receive comments on this proposed AD by May 28, 2013.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2013–0025, dated February 6, 2013 (referred to herein after as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states:

Several power loss events have been reported on Austro E4 engines, due to fracture of the waste gate controller lever. This condition, if not corrected, could lead to further cases of power loss events, possibly


### 18921 Federal Register / Vol. 78, No. 60 / Thursday, March 28, 2013 / Proposed Rules

resulting in forced landing, damage to the aeroplane and injury to occupants. We are proposing this AD to prevent engine power loss or in-flight shutdown, which could result in loss of control and damage to the airplane. You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

Austro Engine GmbH has issued Mandatory Service Bulletin No. MSB– E4–007/3, Revision 3, dated November 28, 2012. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This Proposed AD

This product has been approved by the aviation authority of Austria, and is approved for operation in the United States. Pursuant to our bilateral agreement with Austria, EASA has notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. This proposed AD would require removing from service waste gate controllers, P/N E4A–41–120–000 Rev. 050 or lower, and waste gate controllers, P/N E4B–41– 120–000 Rev. 000 during the next engine maintenance, or within 110 flight hours or three months after the effective date of the AD, whichever occurs first. Costs of Compliance

We estimate that this proposed AD affects 72 engines installed on airplanes of U.S. registry. We also estimate that it would take about one hour per engine to comply with this proposed AD. The average labor rate is $85 per hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $6,120. Our cost estimate is exclusive of possible warranty coverage. 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 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 this 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); and

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.

We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

(e) Actions and Compliance

Unless already done, do the following during the next engine maintenance, or within 110 flight hours or within three months after the effective date of this AD, whichever occurs first.

(f) Remove from service waste gate controllers, P/N E4A–41–120–000 Rev. 050 or lower revision, and waste gate controllers, P/N E4B–41–120–000 Rev. 000.
(g) Installation Prohibition

**Airworthiness Directives; The Boeing Company Airplanes** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 707–300, 707–300B, and 707–300C series airplanes; and certain Model 727C, 727– 100C, and 727–200F series airplanes. This proposed AD was prompted by a report that a cam latch on the main cargo door (MCD) broke during flight. This proposed AD would require performing repetitive inspections of the MCD cam latches; replacing cam latches, certain bolts, and door hinge fittings; performing related investigative and corrective actions, if necessary; and MCD rigging. We are proposing this AD to detect and correct cracked or damaged cam latches, latch pins, and latch pin cross bolts, which could reduce the structural integrity of the MCD, and result in rapid decompression of the airplane and potential loss of the MCD during flight.

**DATES :**  We must receive comments on this proposed AD by May 13, 2013.

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

Discussion

We received a report that the forwardmost cam latch on the forward center cam latch pair (cam latch number 3) on the MCD broke during flight on a Model 757 airplane. That airplane had accumulated 20,000 total flight hours and 9,500 total flight cycles when the cam latch broke.

Certain Model 707–300, 707–300B, and 707–300C series airplanes; and certain Model 727C, 727–100C, and 727–200F series airplanes; have an MCD with a similar design to the MCD on the Model 757 airplane. Therefore, those Model 707–300, 707–300B, and 707– 300C series airplanes; and Model 727C, 727–100C, and 727–200F series airplanes; might be subject to the unsafe condition revealed on Model 757 airplanes.

The MCD is an outward-hinging door that requires a locking mechanism to keep the door closed. The latch pins in the lower sill of the MCD interlock with the cam latches installed in the bottom of the MCD. When a latch pin interlocks with a cam latch, the cam latch rotates into the closed position and holds the door closed. We are proposing this AD to detect and correct cracked or damaged cam latches, latch pins, and latch pin cross bolts, which could reduce the structural integrity of the MCD, and result in rapid decompression of the airplane and potential loss of the MCD during flight.

Relevant Service Information

We reviewed Boeing 707 Alert Service Bulletin A3536, dated February 6, 2012 (for Model 707–300, 707–300B, and 707–300C series airplanes); and Boeing Alert Service Bulletin 727–52A0150, dated January 30, 2012 (for Model 727C, 727–100C, and 727–200F series airplanes).
