Airworthiness Directives; DG 

Flugzeugbau GmbH Models DG–800B 

and DG–500MB Sailplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain DG Flugzeugbau GmbH Models 

DG–800B and DG–500MB sailplanes. 

This proposed AD would require you to 

modify the connection of the starter ring 

gear to the lower drive belt pulley 

adapter. This proposed AD results from 

mandatory continuing airworthiness 

information (MCAI) issued by the 

airworthiness authority for Germany. 

We are issuing this proposed AD to 

prevent the bolts currently used to 

connect the starter ring gear to the drive 

belt pulley adapter from shearing off 

and the bolt heads falling into the 

engine compartment. Failure of this 

connection could render the engine 

inoperative. Consequently, this failure 

could lead to loss of control of the 

sailplane. 

DATES: We must receive any comments 

on this proposed AD by November 9, 

2005.

Discussion 

What events have caused this 

proposed AD? The Luftfahrt-Bundesamt 

(LBA), which is the airworthiness 

authority for Germany, recently notified 

FAA that an unsafe condition may exist 

on certain DG Flugzeugbau GmbH 

58108 Federal Register / Vol. 70, No. 192 / Wednesday, October 5, 2005 / Proposed Rules 

Models DG–800B and DG–500MB 

sailplanes. The LBA reports that sheared 

off bolt heads have been found in the 

engine compartment of approximately 

20 of the specified sailplanes. These 

bolts connect the starter ring gear to the 

lower drive belt pulley adapter. Failure 

of this connection could render the 

engine inoperative. 

What is the potential impact if FAA 

took no action? The bolts currently used 

to connect the starter ring gear to the 

drive belt pulley adapter may shear off 

and the bolt heads could fall into the 

engine compartment. Failure of this 

connection could render the engine 

inoperative. Consequently, this failure 

could lead to loss of control of the 

sailplane. 

Is there service information that 

applies to this subject? DG-Flugzeugbau 

GmbH has issued Working Instruction 

No. 1 for TN 873/30, dated June 9, 2004; 

and Technical Note No. 873/30 and No. 

843/22, approved by LBA on June 29, 

2004, and approved by the European 

Aviation Safety Agency on July 9, 2004. 

What are the provisions of this service 

information? The service information 

includes procedures for: 

—Removing the starter ring gear 

assembly with adapter and lower 

pulley; 

—Modifying the connection area where 

the bolts connect the starter ring gear 

to the lower drive belt pulley adapter; 

and 

—Reinstalling the starter ring gear 

assembly with the adapter and lower 

pulley. 

What action did the LBA take? The 

LBA classified this service information 

as mandatory and issued German AD 

Number D–2004–347, dated July 2, 

2004, to ensure the continued 

airworthiness of these sailplanes in 

Germany. 

Did the LBA inform the United States 

under the bilateral airworthiness 

agreement? These DG Flugzeugbau 

GmbH Models DG–800B and DG–

500MB sailplanes are manufactured in 

Germany and are type-certificated for 

operation in the United States under the 

provisions of section 21.29 of the 

Federal Aviation Regulations (14 CFR 

21.29) and the applicable bilateral 

airworthiness agreement. 

Under this bilateral airworthiness 

agreement, the LBA has kept us 

informed of the situation described 

above. 

FAA’s Determination and Requirements 

of This Proposed AD 

What has FAA decided? We have 

examined the LBA’s findings, reviewed 

all available information, and 

determined that AD action is necessary 

for products of this type design that are 

certificated for operation in the United 

States. 

Since the unsafe condition described 

previously is likely to exist or develop 

on other DG Flugzeugbau GmbH Models 

DG–800B and DG–500MB sailplanes of 

the same type design that are registered 

in the United States, we are proposing 

AD action to prevent the bolts currently 

used to connect the starter ring gear to 

the drive belt pulley adapter from 

shearing off and the bolt heads falling 

into the engine compartment. Failure of 

this connection could render the engine 

inoperative. Consequently, this failure 

could lead to loss of control of the 

sailplane. 

What would this proposed AD 

require? This proposed AD would 

require you to incorporate the actions in 

the previously-referenced service 

information. 

How does the revision to 14 CFR part 

39 affect this proposed AD? On July 10, 

2002, we published a new version of 14 

CFR part 39 (67 FR 47997, July 22, 

2002), which governs FAA’s AD system. 

This regulation now includes material 

that relates to altered products, special 

flight permits, and alternative methods 

of compliance. This material previously 

was included in each individual AD. 

Since this material is included in 14 

CFR part 39, we will not include it in 

future AD actions. 

Costs of Compliance 

How many sailplanes would this 

proposed AD impact? We estimate that 

this proposed AD affects 7 sailplanes in 

the U.S. registry. 

What would be the cost impact of this 

proposed AD on owners/operators of the 

affected sailplanes? We estimate the 

following costs to do this proposed 

modification: 

Labor cost Parts 

cost 

Total cost per 

sailplane 

Total cost on 

U.S. operators 

3 workhours × $65 = $195 ...................................................................................................................... $21 $216 $1,512 

Authority for This Rulemaking 

What authority does FAA have for 

issuing this rulemaking action? 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 AD. 

Regulatory Findings 

Would this proposed AD impact 

various entities? We have 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. 

Would this proposed AD involve a 

significant rule or regulatory action? For 

the reasons discussed above, I certify 

that this proposed 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); 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 summary of the costs 

to comply with this proposed AD (and 

other information as included in the 

Regulatory Evaluation) and placed it in 

the AD Docket. You may get a copy of 

this summary by sending a request to us 

at the address listed under ADDRESSES. 

Include ‘‘AD Docket FAA–2005–22206; 

Directorate Identifier 2005–CE–45–AD’’

in your request.
