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 certain 

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

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

and 1S1 turboshaft engines. This 

proposed AD was prompted by a finding 

that the engine’s tachometer unit cycle 

counting feature is unreliable. This 

proposed AD would require daily postflight checks of the engine tachometer’s 

unit cycle counting feature. This 

proposed AD would also require 

ground-run functional checks within 

every 1,000 operating hours. This 

proposed AD was prompted by detailed 

analysis and review of the accuracy of 

the engine’s tachometer cycle counting 

feature. We are proposing this AD to 

prevent uncontained engine failure and 

damage to the helicopter. 

DATES: We must receive comments on 

this proposed AD by February 11, 2013. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD 2012– 

0187, dated September 18, 2012 

(referred to hereinafter as ‘‘the MCAI’’), 

to correct an unsafe condition for the 

specified products. The MCAI states: 

Following detailed analysis and review of 

in-service feedback performed by Turbomeca 

on the Arriel 1 engines, the chapter 05–10 

Airworthiness Limitation Section (ALS) of 

Arriel 1 Maintenance Manuals has been 

updated in order to clarify the definition and 

update the requirements relative to the cycle 

counting aid system (modification 

introduced in production by Turbomeca 

modification TU207 or TU243 and in-service, 

respectively, by Turbomeca Service Bulletin 

(SB) 292 80 0190 or SB 292 80 0168), add 

associated maintenance tasks, and modify the 

Power Turbine (PT) partial cycle counting 

method. 

The SBs referenced above introduced 

the tachometer. The tachometer’s cycle 

counting feature, in some instances, 

produced results inconsistent with 

ground run checks. The inaccurate cycle 

counting results of the tachometer can 

lead to exceeding life limits on critical 

rotating parts, which can cause 

uncontained engine failure. Further 

information may be obtained by 

examining the MCAI in the AD docket. 

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 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 daily postflight checks of the engine tachometer’s 

unit cycle counting feature. This 

mstockstill on DSK4VPTVN1PROD with 

73558 Federal Register / Vol. 77, No. 238 / Tuesday, December 11, 2012 / Proposed Rules 

proposed AD would also require 

ground-run functional checks within 

every 1,000 operating hours. 

Costs of Compliance 

We estimate that this proposed AD 

would affect about 1,420 engines 

installed in helicopters of U.S. registry. 

We also estimate that it would take 

about 30 minutes per engine to perform 

a check of the engine’s tachometer unit 

cycle counting feature and that an 

average of 320 checks would be required 

per year. Based on the average annual 

operating hours for an engine, a 1,000 

operating hour functional check would 

not be required for at least one year. The 

average labor rate is $85 per hour. No 

parts would be required. Based on these 

figures, we estimate the average total 

cost of the proposed AD on U.S. 

operators to perform checks of the 

tachometer cycle counting unit for a 

year, is $19,312,000. 

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); and 

3. 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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 AD: 

Turbomeca S.A.: Docket No. FAA–2012– 

1131; Directorate Identifier 2012–NE– 

34–AD. 

(a) Comments Due Date 

We must receive comments by February 

11, 2013. 

(b) Affected Airworthiness Directives (ADs) 

None. 

(c) Applicability 

This AD applies to Turbomeca S.A. Arriel 

1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 

1K1, 1S, and 1S1 turboshaft engines that 

have incorporated Modification TU 207 or 

TU 243, or have incorporated Turbomeca 

Service Bulletin (SB) No. 292 80 0168 or SB 

No. 292 80 0190. 

(d) Reason 

This AD was prompted by detailed 

analysis and review of the accuracy of the 

engine’s tachometer cycle counting feature. 

We are issuing this AD to prevent 

uncontained engine failure and damage to 

the helicopter. 

(e) Actions and Compliance 

(1) During the post flight maintenance 

inspection after the last flight of each day, 

compare the cycles counted by the engine’s 

tachometer unit with the cycles counted by 

the primary counting method. 

(2) If the numbers are different, use the 

primary counting method thereafter to 

determine all cycle counts. Do not use the 

values from the tachometer unit cycle 

counting feature. 

(3) If the engine tachometer cycle counting 

feature remains accurate, then every 1,000 

operating hours, perform a ground-run 

functional check of the tachometer unit cycle 

counting feature. If the counting feature fails 

the check, thereafter use only the primary 

cycle counting method to count cycles. 

(4) If the tachometer is replaced, follow 

instructions in paragraphs (e)(1), (e)(2), and 

(e)(3) of this AD. 

(f) 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.
