Airworthiness Directives; Turbomeca 

S.A. Turboshaft 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 

Turbomeca S.A. Arriel 1A1, 1A2, 1B, 

1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, 

1S1, 2B, 2B1, 2C, 2C1, 2C2, 2S1, and 

2S2 turboshaft engines. This proposed 

AD was prompted by reports of 

uncommanded in-flight shutdowns on 

Turbomeca S.A. Arriel 1 and Arriel 2 

engines following rupture of the 41- 

tooth gear forming part of the 41/23- 

tooth bevel gear located in the engine 

accessory gearbox (AGB). This proposed 

AD would require an initial one-time 

vibration check of the engine AGB on 

certain higher risk Arriel 1 and Arriel 2 

model engines. This proposed AD 

would also require repetitive vibration 

checks of the engine AGB for all Arriel 

1 and Arriel 2 engines at every engine 

shop visit. We are proposing this AD to 

prevent failure of the engine AGB, 

which could lead to in-flight shutdown 

and damage to the engine, which may 

result in damage to the aircraft. 

DATES: We must receive comments on 

this proposed AD by August 4, 2014.

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– 

0036, dated February 11, 2014 (referred 


ehiers on DSK2VPTVN1PROD with PROPOSALS
32196 Federal Register / Vol. 79, No. 107 / Wednesday, June 4, 2014 / Proposed Rules 

to herein after as ‘‘MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

Several cases of uncommanded in-flight 

shut-down (IFSD) have been reported on 

ARRIEL 1 or ARRIEL 2 engines following 

rupture of the 41-tooth gear forming part of 

the 41/23 tooth bevel gear located in the 

accessory gearbox (AGB) within engine 

module M01. 

Results of subsequent investigations 

showed that the meshing quality of the bevel 

gear may have contributed to tooth rupture. 

The rupture of the AGB 41-tooth gear may 

lead to loss of driving of equipment essential 

to engine operation. 

This condition if not detected and 

corrected, could lead to an uncommanded 

engine in-flight shut-down and may 

ultimately lead to an emergency landing. 

We are proposing an initial one-time 

vibration check of the engine AGB on 

certain higher risk Arriel 1 and Arriel 2 

model engines. We are also proposing 

repetitive vibration checks of the engine 

AGB for all Arriel 1 and Arriel 2 engines 

at every engine shop visit. You may 

examine the MCAI in the AD docket on 

the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2014– 

0164. 

Relevant Service Information 

Turbomeca S.A. has issued 

Mandatory Service Bulletin (MSB) No. 

292 72 0839, Version B, dated 

November 25, 2013, and MSB No. 292 

72 2849, Version B, dated November 25, 

2013. The service information describes 

procedures for correcting the unsafe 

condition described in the MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of France and is 

approved for operation in the United 

States. Pursuant to our bilateral 

agreement with the European 

Community, 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 vibration 

checks of the 41/23-tooth bevel gear 

assembly of the AGB on certain 

Turbomeca S.A. Arriel 1 and Arriel 2 

model turboshaft engines and, if a 

discrepancy is found, replacement of 

the AGB with a part eligible for 

installation. 

Costs of Compliance 

We estimate that this proposed AD 

affects 1,268 engines installed on 

aircraft of U.S. registry. We also estimate 

that it would take about 4 hours per 

engine to comply with the inspection 

requirement in this proposed AD. The 

average labor rate is $85 per hour. Based 

on these figures, we estimate the cost of 

this proposed AD on U.S. operators to 

be $431,120. 

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 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.

Airworthiness Directives; Pratt & 

Whitney Division Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

airworthiness directive (AD) 2013–15– 

09, which applies to all Pratt & Whitney 

Division (PW) PW4074, PW4074D, 

PW4077, PW4077D, PW4084D, 

PW4090, and PW4090–3 turbofan 

engine models with certain second-stage 

high-pressure turbine (HPT) air seals, 

installed. AD 2013–15–09 currently 

requires initial and repetitive 

inspections for cracks in second-stage 

HPT air seals. Since we issued AD 

2013–15–09, we received reports of 

cracking in the original location on two 

additional part numbers (P/Ns) as well 

as reports of through-cracks in a new 

location in the second-stage HPT air 

seal. PW has developed a redesigned 

second-stage HPT air seal that addresses 

the cracking condition in both locations. 

This proposed AD would expand the 

applicability of AD 2013–15–09 to 

include additional P/Ns, require 

replacement of the mating hardware if 

the second-stage HPT air seal is found 

with a through-crack, and add 

mandatory terminating action to the 

repetitive inspections. We are proposing 

this AD to prevent failure of the secondstage HPT air seal, which could lead to 

uncontained engine failure and damage 

to the airplane. 

DATES: We must receive comments on 

this proposed AD by August 4, 2014. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following
