AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Pilatus Aircraft Ltd. Models PC–6, PC– 

6–H1, PC–6–H2, PC–6/350, PC–6/350– 

H1, PC–6/350–H2, PC–6/A, PC–6/A–H1, 

PC–6/A–H2, PC–6/B–H2, PC–6/B1–H2, 

PC–6/B2–H2, PC–6/B2–H4, PC–6/C–H2, 

and PC–6/C1–H2 airplanes that would 

supersede AD 2013–11–08. This 

proposed AD results from mandatory 

continuing airworthiness information 

(MCAI) originated by an aviation 

authority of another country to identify 

and correct an unsafe condition on an 

aviation product. The MCAI describes 

the unsafe condition as a need to 

incorporate new revisions into the 

aircraft maintenance manual or in the 

limitations document of the FAAapproved maintenance program. We are 

issuing this proposed AD to require 

actions to address the unsafe condition 

on these products. 

DATES: We must receive comments on 

this proposed AD by November 3, 2014.

Discussion 

On May 22, 2013, we issued AD 

2013–11–08, Amendment 39–17468 (78 

FR 37701; June 24, 2013). That AD 

required actions intended to address an 

unsafe condition on Pilatus Aircraft Ltd. 

Models PC–6, PC–6–H1, PC–6–H2, PC– 

6/350, PC–6/350–H1, PC–6/350–H2, 

PC–6/A, PC–6/A–H1, PC–6/A–H2, PC– 

6/B–H2, PC–6/B1–H2, PC–6/B2–H2, 

PC–6/B2–H4, PC–6/C–H2, and PC–6/

C1–H2 airplanes and was based on 

mandatory continuing airworthiness 

information (MCAI) originated by an 

aviation authority of another country. 

Since we issued AD 2013–11–08, 

Amendment 39–17468 (78 FR 37701; 

June 24, 2013), Pilatus Aircraft Ltd. has 

issued revisions to the Limitations 

section of the airplane maintenance 

manual (AFM) to incorporate new life 

limits for the fire extinguisher. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No. 2014– 

0181, dated July 31, 2014 (referred to 

after this as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

The maintenance instructions and 

airworthiness limitations applicable to the 

Structure and Components of PC–6 

aeroplanes are specified in the Aircraft 

Maintenance Manual (AMM) under Chapter 

4 or in the Airworthiness Limitations 

Document (ALS), depending on aeroplane 

model. 

The instructions contained in the ALS 

document have been identified as mandatory 

actions for continued airworthiness and 

failure to comply with these instructions and 

limitations could potentially lead to an 

unsafe condition. 

Pilatus Aircraft Ltd. (Pilatus) recently 

issued PC–6 AMM, Chapter 04–00–00, 

Document Number 01975 issue 19 for PC–6 

B2–H2 and PC–6 B2–H4 aeroplanes and PC– 

6 ALS, Document Number 02334 issue 4 for 

all other PC–6 aeroplane models to 

incorporate new life limits for the Fire 

Extinguisher. 

For the reason described above, this AD 

retains the requirements of EASA AD 2012– 

0268, which is superseded, and requires 

implementation of the new maintenance 

requirements and/or airworthiness 

limitations. 

You may examine the MCAI on the 

Internet at http://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2014–0717.

56024 Federal Register / Vol. 79, No. 181 / Thursday, September 18, 2014 / Proposed Rules 

Relevant Service Information 

Pilatus Aircraft Ltd. has issued 

Airworthiness Limitations, document 

No. 02334, dated May 31, 2014; and 

Airworthiness Limitations, document 

04–00–00, dated May 31, 2014. The 

actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. 

FAA’s Determination and Requirements 

of the Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with this State of 

Design Authority, they have 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 and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 50 products of U.S. registry. 

We also estimate that it would take 

about 8 work-hours per product to 

comply with the basic requirements of 

this proposed AD. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $34,000, or $680 per 

product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 1 work-hour and require parts 

costing $1,000, for a cost of $1,085 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

The only costs that would be imposed 

by this proposed AD over that already 

required by AD 2013–11–08 is 1 workhour to incorporate the new 

airworthiness limitations section 

sections into the maintenance program, 

$1,085 for replacement of the fire 

extinguisher if needed, and the addition 

of 35 airplanes from 15 airplanes to 50 

airplanes. 

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), 

(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.

condition on an aviation product. The MCAI 

describes the unsafe condition as a need to 

incorporate new revisions into the aircraft 

maintenance manual (AMM) or in the 

Limitations document of the FAA-approved 

maintenance program. The limitations were 

revised to incorporate new life limits for the 

fire extinguisher. These actions are required 

to ensure the continued operational safety of 

the affected airplanes. 

(f) Actions and Compliance 

(1) Actions retained from AD 2013–11–08,

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Rolls-Royce plc (RR) RB211 Trent 768– 

60, 772–60, and 772B–60 turbofan 

engines. This proposed AD was 

prompted by fractures of the highpressure/intermediate-pressure (HP/IP) 

turbine support internal oil feed tube. 

This proposed AD would require 

inspection of the oil feed tube sealing 

sleeve and removal of those oil feed 

tube sealing sleeves that fail inspection. 

We are proposing this AD to prevent 

failure of the HP/IP turbine support 

internal oil feed tube, which could 

result in uncontained engine failure and 

damage to the airplane.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD 2014– 

0168, dated July 16, 2014 (referred to 

hereinafter as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

There have been nine occurrences of high oil 

consumption, caused by fracture of the High/ 

Intermediate Pressure (HP/IP) turbine 

support internal oil feed tube Part Number 

(P/N) FW45909. 

The oil feed tube threaded end adaptor and 

sealing sleeve P/N FW15003 are designed to 

form a sliding joint which, if restrained, can 

compress the oil feed tube during thermal 

contraction of the turbine casing at the end
