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

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.
