Airworthiness Directives; Turbomeca 

S.A. Turboshaft Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding 

airworthiness directive (AD) 2007–10– 

07 for all Turbomeca S.A. Arriel 2B, 

2B1, and 2B1A turboshaft engines. AD 

2007–10–07 required an inspection of 

the splines of the coupling assembly 

and the hydro-mechanical metering unit 

(HMU) drive gear shaft for wear. This 

AD requires the same inspection and 

expands the affected population. This 

AD also removes Arriel 2B1A engines 

from the applicability. We are issuing 

this AD to prevent failure of the HMU 

drive gear shaft, which could lead to 

damage to the engine and damage to the 

airplane. 

DATES: This AD is effective August 4, 

2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of August 4, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2007–10–07, 

Amendment 39–15048 (72 FR 26711, 

May 11, 2007), (‘‘AD 2007–10–07’’). AD 

2007–10–07 applied to the specified 

products. The NPRM published in the 

Federal Register on February 21, 2014 

(79 FR 9868). The NPRM proposed to 

require the same inspection as AD 

2007–10–07 and expand the affected 

population. The NPRM also proposed to 

remove Arriel 2B1A engines from the 

applicability. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (79 

FR 9868, February 21, 2014). 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting this AD 

as proposed. 

Costs of Compliance 

We estimate that this AD affects 470 

engines installed on aircraft of U.S. 

registry. We also estimate that it will 

take about 2 hours per engine to comply 

with this AD. The average labor rate is 

$85 per hour. Based on these figures, we 

estimate the cost of this AD on U.S. 

operators to be $79,900. 

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 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.

safety, Incorporation by reference, 

Safety. 

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends part 39 of the Federal 

Aviation Regulations (14 CFR part 39) as

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by 

removing airworthiness directive (AD) 

2007–10–07, Amendment 39–15048 (72 

FR 26711, May 11, 2007), and adding 

the following new AD: 

2014–12–05 Turbomeca S.A: Amendment 

39–17866; Docket No. FAA–2006–23809; 

Directorate Identifier 2005–NE–52–AD. 

(a) Effective Date 

This AD is effective August 4, 2014. 

(b) Affected ADs 

This AD supersedes AD 2007–10–07,

This AD applies to all Turbomeca S.A. 

Arriel 2B, 2B1, 2C, 2C1, 2C2, 2S1, and 2S2 

turboshaft engines. 

(d) Unsafe Condition 

This AD was prompted by a report of an 

additional case of wear of the hydromechanical metering unit (HMU) drive gear 

shaft splines on both Turbomeca S.A. Arriel 

2 engines on a twin-engine helicopter. We are 

issuing this AD to prevent failure of the HMU 

drive gear shaft, which could lead to damage 

to the engine and damage to the aircraft. 

(e) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(1) Arriel 2B and 2B1 Engines 

(i) If on the effective date of this AD the 

HMU has 500 or more operating hours since 

new or since last overhaul, then within 25 

HMU operating hours from the effective date 

of this AD, inspect the high-pressure (HP) 

pump drive gear shaft splines and coupling 

shaft assembly splines. Use paragraph 

2.B.(1)(b) of Turbomeca S.A. Mandatory 

Service Bulletin (MSB) No. 292 73 2812, 

Version G, dated June 24, 2013, to do your 

inspection. 

(ii) If on the effective date of this AD the 

HMU has less than 500 operating hours since 

new or since last overhaul, then inspect the 

HP pump drive gear shaft splines and 

coupling shaft assembly splines between 500 

and 525 operating hours since new or since 

last overhaul. Use paragraph 2.B.(1)(b) of 

Turbomeca S.A. MSB No. 292 73 2812,

new, since last overhaul, or if HMU operating 

hours are unknown, then within 200 HMU 

operating hours from the effective date of this 

AD, inspect the HP pump drive gear shaft 

splines and coupling shaft assembly splines. 

Use paragraph 2.B.(1)(b) of Turbomeca S.A. 

MSB No. 292 73 2822, Version F, dated June 

21, 2013, to do your inspection. 

(ii) If on the effective date of this AD the

operating hours since new or since last 

overhaul, then within 225 HMU operating 

hours, but no earlier than 500 or later than 

700 HMU operating hours from the effective 

date of this AD, inspect the HP pump drive 

gear shaft splines and coupling shaft 

assembly splines. Use paragraph 2.B.(1)(b) of 

Turbomeca S.A. MSB No. 292 73 2822 

Version F, dated June 21, 2013, to do your 

inspection.

of Turbomeca S.A. MSB No. 292 73 2822, 

Version F, dated June 21, 2013, to do your 

inspection. 

(f) Credit for Previous Actions 

If, before the effective date of this AD, you 

inspected your HMU after 500 HMU

overhaul using an earlier version of 

Turbomeca S.A. MSB No. 292 73 2822, 

Version F, dated June 21, 2013, for 2C, 2C1, 

2C2, 2S1 and 2S2 engines, or MSB No. 292 

73 2812, Version G, dated June 24, 2013, for 

2B or 2B1 engines, you have met the 

requirements of this AD. 

(g) Installation Prohibition 

After the effective date of this AD, do not 

install any HMU onto any engine, nor install 

any engine onto any helicopter with an HMU 

affected by this AD, unless the HMU passed 

the inspection required by paragraph (e)(1) of
