14 CFR Part 39 

[Docket No. FAA–2012–0546; Directorate 

Identifier 2012–NE–15–AD; Amendment 39– 

17253; AD 2012–22–16]

Airworthiness Directives; Pratt & 

Whitney Division Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all Pratt 

& Whitney Division PW4050, PW4052, 

PW4056, PW4060, PW4060A, 

PW4060C, PW4062, PW4062A, 

PW4152, PW4156, PW4156A, PW4158, 

PW4160, PW4460, PW4462, and 

PW4650 turbofan engines, including 

models with any dash number suffix. 

This AD was prompted by 16 reports of 

damaged or failed 3rd stage lowpressure turbine (LPT) duct segments. 

This AD requires removing from service 

certain part numbers (P/Ns) of 3rd stage 

LPT duct segments. We are issuing this 

AD to prevent failure of the 3rd stage 

LPT duct segments, which could lead to 

LPT rotor damage, uncontained engine 

failure, and damage to the airplane. 

DATES: This AD is effective December 

19, 2012. 

ADDRESSES: For service information 

identified in this AD, contact Pratt & 

Whitney, 400 Main St., East Hartford, 

CT 06108; phone: 860–565–8770; fax: 

860–565–4503. You may review copies 

of the referenced service information at 

the FAA, Engine & Propeller Directorate,

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM published in the Federal 

Register on July 11, 2012 (77 FR 40822). 

That NPRM proposed to require removal 

from service of 3rd stage LPT duct 

segments P/Ns 50N095; 50N095–001; 

50N235; 50N235–001; 50N494–01; 

50N494–001; 50N495–01; and 50N495– 

001, at the next piece-part exposure 

after the effective date of the proposed 

AD. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal and the FAA’s 

response to each comment. 

Agreement With the Proposed AD 

One commenter, Boeing, agreed with 

the intent of the proposed AD. 

Request To Reference Pratt & Whitney 

Service Bulletin PW4ENG 72–488 

One commenter, FedEx Express, 

requested that we add a reference to 

Pratt & Whitney Service Bulletin 

PW4ENG 72–488 for a list of the engine 

serial numbers affected. We assume this 

request was made to add clarity. 

We do not agree. The AD applicability 

is for PW4000 engines with certain P/N 

3rd stage LPT duct segments installed. 

Although the Pratt & Whitney Service 

Bulletin does list engine serial numbers, 

it is not necessary to include this 

information in the AD. We did not 

change the AD. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

as proposed.

Costs of Compliance 

We estimate that this AD will affect 

151 engines installed on airplanes of 

U.S. registry. We estimate that no 

additional labor costs will be incurred 

to perform the required work as the 

work is done when the 3rd stage LPT 

duct segments are at piece-part 

exposure. The average labor rate is $85 

per work-hour. Required parts will cost 

about $44,441 per engine. Based on 

these figures, we estimate the total cost 

of the AD to U.S. operators will be 

$6,710,591. 

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.

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as

(d) Unsafe Condition 

This AD was prompted by 16 reports of 

damaged or failed 3rd stage LPT duct

failure of the 3rd stage LPT duct segments, 

which could lead to LPT rotor damage, 

uncontained engine failure, and damage to 

the airplane.

Comply with this AD within the 

compliance times specified, unless already 

done. 

(f) 3rd Stage LPT Duct Segments Removal

3rd stage LPT duct segments, P/Ns 50N095; 

50N095–001; 50N235; 50N235–001; 50N494–

install into any engine any 3rd stage LPT 

duct segment, P/N 50N095; 50N095–001; 

50N235; 50N235–001; 50N494–01; 50N494– 

001; 50N495–01; or 50N495–001, that is at 

piece-part exposure. 

(h) Definition 

For the purpose of this AD, piece-part 

exposure is when the 3rd stage LPT duct 

segment is removed from the engine and 

completely disassembled. 

(i) Alternative Methods of Compliance 

(AMOCs) 

The Manager, Engine Certification Office, 

may approve AMOCs for this AD. Use the 

procedures found in 14 CFR 39.19 to make 

your request.
