### 64003 Federal Register / Vol. 76, No. 200 / Monday, October 17, 2011 / Rules and Regulations

Adoption of the Amendment

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

**PART 39—AIRWORTHINESS DIRECTIVES** 

■ 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.
**§ 39.13 [Amended]**

■ 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): 2011–20–51 Pratt & Whitney Canada: Amendment 39–16843; Docket No. FAA–2011–1038; Directorate Identifier 2011–NE–31–AD. (a) Effective Date

This AD is effective November 1, 2011 to all persons except those persons to whom it was made immediately effective by Emergency AD 2011–20–51, issued on September 15, 2011, which contained the requirements of this amendment. (b) Affected ADs

None. (c) Applicability

This AD applies to Pratt & Whitney Canada PT6A–15AG, –27, –28, –34, –34AG, –34B, and –36 series turboprop engines that have had maintenance done to the power section module involving first stage reduction sun gear replacement since February 3, 2010, and having a Timken Alcor Aerospace Technologies, Inc. (TAATI) part manufacturer approval (PMA) replacement first stage reduction sun gear, part number (P/N) E3024765, serial numbers (S/Ns) PC5– 091 through PC5–176, installed. (d) Unsafe Condition

This AD was prompted by failures of certain first stage reduction sun gears, manufactured by TAATI. We are issuing this AD to prevent failure of the shaft portion of the sun gear, which will result in an engine in-flight shut down, possible uncontained engine failure, aircraft damage, and serious injuries. (e) Compliance

Comply with this AD within the compliance times specified, unless already done.

(f) For affected engines, remove the PMA replacement TAATI first stage reduction sun gear and the interacting planet gears from the propeller reduction gearbox assembly within 15 operating hours or 15 days after the effective date of this AD, whichever occurs first. (g) Installation Prohibition

After the effective date of this AD, do not install on any airplane, any engine or power section module with a TAATI PMA replacement first stage reduction sun gear, P/ N E3024765, S/Ns PC5–091 through PC5– 176. (h) Alternative Methods of Compliance (AMOCs)

The Manager, Los Angeles Aircraft Certification Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. (i) Related Information

**SUPPLEMENTARY INFORMATION :**  Airworthiness Directive 2011–18–07, Amendment 39–16789 (76 FR 57900, September 19, 2011), currently requires a one time inspection of spline teeth on the fuel metering pump shaft for excessive wear, for WSK PZL–10W series turboshaft engines.

As published, paragraph (a) of the Amended section is incorrect.

No other part of the preamble or regulatory information has been changed; therefore, only the changed portion of the final rule is being published in the Federal Register.
