SUPPLEMENTARY INFORMATION: 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No.: 2013– 

0217–E, dated September 16, 2013 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the 

specified products. The MCAI states: 

An occurrence of Solo 2350 C engine shaft 

failure and consequent propeller detachment 

was reported. The preliminary investigation 

revealed that the failed shaft was earlier 

modified in accordance with an approved 

method. 

This condition, if not corrected, could lead 

to additional cases of release of the propeller 

from the engine, possibly resulting in damage 

to the sailplane, or injury to persons on the 

ground. 

For the reasons described above, this AD 

prohibits operation of the engine. 

This AD is considered to be a temporary 

measure and further AD action will follow. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating it in Docket No. FAA– 

2013–0929. 

FAA’s Determination and Requirements 

of the 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 issuing this 

AD because we evaluated all 

information provided by the State of 

Design Authority and determined the 

unsafe condition exists and is likely to 

exist or develop on other products of the 

same type design. 

We will work with the type certificate 

holder and EASA to evaluate 

information and to develop an engine 

modification. Based on this, we may 

initiate further rulemaking action to 

address the unsafe condition identified 

in this AD. 

FAA’s Determination of the Effective 

Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD. The FAA has found that the risk to 

the flying public justifies waiving notice 

and comment prior to adoption of this 

rule because engine shaft failure and 

consequent propeller detachment could 

cause damage to the glider and could 

cause injury to persons on the ground. 

Therefore, we determined that notice 

and opportunity for public comment 

before issuing this AD are impracticable 

and that good cause exists for making 

this amendment effective in fewer than 

30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not precede it by notice and 

opportunity for public comment. We 

invite you to send any written relevant 

data, views, or arguments about this AD. 

Send your comments to an address 

listed under the ADDRESSES section. 

Include ‘‘Docket No. FAA–2013–0929; 

Directorate Identifier 2013–CE–031– 

AD’’ at the beginning of your comments. 

We specifically invite comments on the 

overall regulatory, economic,

65870 Federal Register / Vol. 78, No. 213 / Monday, November 4, 2013 / Rules and Regulations 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this AD because of those 

comments. 

We will post all comments we 

receive, without change, to http://

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this AD. 

Costs of Compliance 

We estimate that this AD will affect 2 

products of U.S. registry. We also 

estimate that it will take about .5 workhour per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate 

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

be $85, or $42.50 per product. 

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 that 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.

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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: 

2013–22–14 DG Flugzeugbau GmbH: 

Amendment 39–17646; Docket No. 

FAA–2013–0929; Directorate Identifier 

2013–CE–031–AD. 

(a) Effective Date 

This AD is effective November 25, 2013. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to DG Flugzeugbau GmbH 

Model DG–1000T gliders, all serial numbers, 

that are: 

(1) equipped with a Solo Kleinmotoren 

Model 2350 C engine; and 

(2) certificated in any category. 

(d) Subject 

Air Transport Association of America 

(ATA) Code 72: Engine. 

(e) Reason 

This AD was prompted by 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 engine 

shaft failure and consequent propeller 

detachment. We are issuing this AD to 

prevent engine shaft failure and propeller 

detachment, which could result in damage to 

the glider and injury to persons on the 

ground. 

(f) Actions and Compliance 

Unless already done, do the following 

actions in paragraphs (f)(1) through (f)(3) of 

this AD. 

(1) As of November 25, 2013 (the effective 

date of this AD), do not operate the engine 

unless the engine is modified following 

instructions that are approved by the FAA 

specifically for this AD. Contact the FAA 

office identified in paragraph (g)(1) of this 

AD to get more information about obtaining 

such instructions. 

(2) As of November 25, 2013 (the effective 

date of this AD), place a copy of this AD into 

the limitations section of the aircraft flight 

manual (AFM). 

(3) Modifying the engine following 

instructions approved by the FAA 

specifically for this AD removes the 

prohibited engine operation required in 

paragraph (f)(1) of this AD and removes the 

requirement to incorporate this AD into the 

limitations section of the AFM. 

(g) Other FAA AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, Standards Office, 

FAA, has the authority to approve AMOCs 

for this AD, if requested using the procedures 

found in 14 CFR 39.19. Send information to 

ATTN: Jim Rutherford, Aerospace Engineer, 

FAA, Small Airplane Directorate, 901 Locust, 

Room 301, Kansas City, Missouri 64106; 

telephone: (816) 329–4165; fax: (816) 329– 

4090; email: jim.rutherford@faa.gov. Before 

using any approved AMOC on any glider to 

which the AMOC applies, notify your 

appropriate principal inspector (PI) in the 

FAA Flight Standards District Office (FSDO), 

or lacking a PI, your local FSDO. 

(2) Airworthy Product: For any requirement 

in this AD to obtain corrective actions from 

a manufacturer or other source, use these 

actions if they are FAA-approved. Corrective 

actions are considered FAA-approved if they 

are approved by the State of Design Authority 

(or their delegated agent). You are required 

to assure the product is airworthy before it 

is returned to service.
