Airworthiness Directives; SchemppHirth Flugzeugbau GmbH Gliders 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for 

Schempp-Hirth Flugzeugbau GmbH 

Model Duo Discus T gliders. This AD 

results from mandatory continuing 

airworthiness information (MCAI) 

issued 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 the instructions provided 

to inspect the propeller hub and blades 

are insufficient for detecting cracks and/ 

or other damage, and other operating 

instructions provided by the flight and 

maintenance manual are incorrect and 

insufficient. We are issuing this AD to 

require actions to address the unsafe 

condition on these products. 

DATES: This AD is effective January 28, 

2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of January 28, 2014.

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 was published in the Federal 

Register on July 29, 2013 (78 FR 45471). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

It was found that the accomplishment 

instructions provided to check the powered 

sailplane’s propeller hub and blades were not 

sufficient to detect cracks and/or other 

damage. The results of a subsequent manual 

review revealed that some other operating 

instructions provided by the sailplane flight 

and maintenance manual were neither 

correct nor sufficient. 

This condition, if not corrected, could lead 

to operation of the powered sailplane outside 

its certified limits. 

To address this unsafe condition, EASA 

issued AD 2013–0012 to require amendment 

of sailplane flight- and maintenance manuals 

to correct the operating instruction 

deficiencies and inaccuracies and, for Arcus 

T sailplanes that had been repaired before the 

applicable maintenance manual update, an 

elevator or wing flap hinge moment weight 

check, as applicable. 

Since that AD was published, SchemppHirth Flugzeugbau GmbH determined that 

Action 3 of the accomplishment instructions 

of Technical Note (Technische Mitteilung) 

(TN) 890–13, referenced for Duo Discus T 

sailplanes, was incorrect for S/N 1 through 

174. To correct this erroneous maintenance 

instruction, Schempp-Hirth Flugzeugbau 

GmbH issued TN 890–13 issue 2. 

For the reasons described above, this AD 

retains the requirements of EASA AD 2013– 

0012, which is superseded, and requires, for 

certain Duo Discus T powered sailplanes, the 

use of instructions as provided in TN 890– 

13 issue 2. 

The MCAI requires exchange of flight 

manual pages (which introduces a 

repetitive inspection of the power 

plant), exchange of maintenance manual 

pages, exchange of cockpit placards, and 

transfer of weight and balance data. 

EASA AD No.: 2013–0054, dated March 

5, 2013, supersedes EASA AD No. 

2013–0012, dated January 15, 2013. No

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (78 

FR 45471, July 29, 2013) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (78 FR 

45471, July 29, 2013) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 45471, 

July 29, 2013). 

Costs of Compliance 

We estimate that this AD will affect 5 

products of U.S. registry. We also 

estimate that it will take about 2.5 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $50 per 

product. 

Based on these figures, we estimate 

the cost of this AD on U.S. operators to 

be $1,312.50, or $262.50 per product. 

In addition, we estimate that any 

necessary follow-on actions will take 

about 5 work-hours and require parts 

costing $3,840, for a cost of $4,265 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

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 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 this AD: 

(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.

Airworthiness Directives; Turbomeca 

S.A. Turboshaft Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting 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 AD 

requires a one-time inspection of the 

free turbine (FT) module (M04) for the 

affected Turbomeca S.A. Arriel 1 

engines and, if a discrepancy is found, 

repair of the affected module. This AD 

was prompted by a ‘‘chip illumination 

event’’ in flight on a Turbomeca S.A. 

Arriel 1 engine. We are issuing this AD 

to prevent a loss of FT bearing 

lubrication, resulting in FT module 

failure, damage to the engine, and 

damage to the aircraft. 

DATES: This AD becomes effective 

January 28, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of January 28, 2014.
