Airworthiness Directives; DG 

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 DG 

Flugzeugbau GmbH Model DG–1000T 

gliders equipped with Solo 

Kleinmotoren Model 2350 C engines. 

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 a material defect 

of the propeller shaft, most likely 

caused by a manufacturing error. We are 

issuing this AD to require actions to 

address the unsafe condition on these 

products. 

DATES: This AD is effective March 19, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of March 19, 2013.

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 November 30, 2012 (77 FR 

71359). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Two reports have been received of a broken 

P/N 20 31 211 propeller shaft on a Solo 2350 

C engine. The results of the investigation 

showed that the failures were due to a 

material defect, most likely caused by a 

manufacturing error. 

This condition, if not detected and 

corrected, could lead to failure of the shaft 

and detachment of the propeller from the 

aeroplane, which, depending on the flight 

conditions, could result in reduced control of 

the aeroplane, or injury to persons on the 

ground. 

For the reasons described above, this AD 

requires a one-time inspection (magnetic 

particle or dye penetrant) of the affected 

propeller shafts to detect cracks and, 

depending on findings, replacement of the 

propeller pulley assembly (module) with a 

serviceable module. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM 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 (77 FR 

71359, November 30, 2012) for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 71359, 

November 30, 2012). 

Costs of Compliance 

We estimate that this AD will affect 2 

products of U.S. registry. We also 

estimate that it would take about 1 

work-hour per product to comply with 

the basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts would cost about $0 per 

product. 

Based on these figures, we estimate 

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

be $170, or $85 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 1 work-hour and require parts 

costing $197, for a cost of $282 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.

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: 

2013–03–09 DG Flugzeugbau GmbH: 

Amendment 39–17344; Docket No. 

FAA–2012–1250; Directorate Identifier 

2012–CE–043–AD. 

(a) Effective Date 

This airworthiness directive (AD) becomes 

effective March 19, 2013. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to DG Flugzeugbau GmbH 

Model DG–1000T gliders equipped with Solo 

Kleinmotoren Model 2350 C engines, all

(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 a material 

defect within the propeller shaft, most likely 

caused by a manufacturing error. We are 

issuing this AD to prevent failure of the 

propeller shaft and detachment of the 

propeller, which could result in reduced 

control of the aircraft or injury to persons on 

the ground. 

(f) Actions and Compliance 

Unless already done, do the following 

actions: 

(1) Within 25 hours time-in-service (TIS) 

after March 19, 2013 (the effective date of 

this AD) or 6 months after March 19, 2013 

(the effective date of this AD), whichever 

occurs first, remove the propeller pulley 

assembly (module) from the engine and 

inspect the transition region of the part 

number (P/N) 20 31 211 shaft following the 

Actions section of Solo Kleinmotoren GmbH 

Service Bulletin Nr. 4603–13, Issue 1, dated 

September 24, 2012. 

(2) If, during the inspection required by 

paragraph (f)(1) of this AD, cracks are 

detected in the P/N 20 31 211 shaft, before 

further flight, do the following: 

(i) Replace the P/N 20 31 211 shaft with 

an airworthy P/N 20 31 211 shaft; or 

(ii) Replace the propeller pulley assembly 

(module) with an airworthy propeller pulley 

assembly (module). 

(g) Other FAA AD Provisions 

The following provisions also apply to this 

AD:
