SUPPLEMENTARY INFORMATION:

Discussion

What events have caused this

proposed AD? The Luftfahrt-Bundesamt

(LBA), which is the airworthiness

authority for the Federal Republic of

Germany, recently notified the FAA that

an unsafe condition may exist on all DG

Flugzeugbau GmbH Model DG–800B

sailplanes equipped with a SOLO

engine. The LBA reports that 5

sailplanes had a broken crankshaft or

connecting rod bearing failures.

Improper drive belt tension caused the

damage and failures.

What happens if you do not correct

the condition? This condition, if not

corrected, could result in loss of

propulsion during critical phases of

flight.

Has FAA taken any action to this

point? We issued a proposal to amend

part 39 of the Federal Aviation

Regulations (14 CFR part 39) to include

an AD that would apply to certain DG

Flugzeugbau Model DG 800B sailplanes.

This proposal was published in the

Federal Register as a notice of proposed

rulemaking (NPRM) on August 10, 2000

(65 FR 48931). The NPRM proposed to

measure and correct improper propeller

drive belt tension.

Was the public invited to comment?

Interested persons were afforded an

opportunity to participate in the making

of this amendment. No comments were

received on the proposed rule or the

FAA’s determination of the cost to the

public.

The FAA’s Determination

What is FAA’s Final Determination on

this Issue? After careful review of all

available information related to the

subject presented above, we have

determined that air safety and the

public interest require the adoption of

the rule as proposed except for minor

editorial corrections. We determined

that these minor corrections:

• Will not change the meaning of the

AD; and

• Will not add any additional burden

upon the public than was already

proposed.

What are the differences between the

LBA AD and this AD? The German AD

requires measuring the drive belt

tension within the next 25 hours timein-service but no later than December

31, 1999, on the affected sailplanes

registered in Germany. We require

measuring the drive belt tension within

the next 25 hours time-in-service or 90

days after the effective date of this AD,

whichever occurs first.

Why is the compliance time in both

hours time-in-service and calendar

time? The unsafe condition described in

this AD does not originate as a result of

sailplane operation. Applying improper

tension to the propeller belt drive can

occur at any time. The condition

worsens with sailplane operation, but

could already exist now. The

compliance times afford the following:

• The 25 hours TIS provides that the

high-usage sailplanes are inspected for

improper tension in a reasonable time

period; and

• The 90 day compliance time

provides that improper tension does not

go undetected for a long period of time

on low-usage sailplanes.

Cost Impact

How many sailplanes does this AD

impact? We estimate that this AD affects

6 sailplanes in the U.S. registry.

What is the cost impact of this AD on

owners/operators of the affected

sailplanes? We estimate the following

costs to accomplish the measurement:

Labor cost Parts cost Total cost per sailplane Total cost on U.S. sailplane operators

3 workhours × $60 per hour =

$180..

Not applicable ............................... $180 per sailplane ........................ $180 × 6 = $1,080.

Regulatory Impact

Does this AD impact various entities?

The regulations adopted herein 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. Therefore, it is

determined that this final rule does not

have federalism implications under

Executive Order 13132.

Does this AD involve a significant rule

or regulatory action? For the reasons

discussed above, I certify that this

action (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); 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.

A copy of the final evaluation

prepared for this action is contained in

the Rules Docket. A copy of it may be

obtained by contacting the Rules Docket

2000–20–10 DG Flugzeugbau GMBH:

Amendment 39–11921; Docket No. 99–

CE–90–AD.

(a) What sailplanes are affected by this

AD? Model DG–800B sailplanes, all serial

numbers, that are:

(1) certificated in any category; and

(2) equipped with SOLO engines.

(b) Who must comply with this AD?

Anyone who wishes to operate any of the

above sailplanes on the U.S. Register must

comply with this AD.

60850 Federal Register / Vol. 65, No. 199 / Friday, October 13, 2000 / Rules and Regulations

(c) What problem does this AD address?

The actions specified by this AD are intended

to correct improper drive belt tension and

consequent engine crankshaft or connecting

rod bearing damage. Such damage could

result in loss of propulsion during critical

phases of flight.

(d) What actions must I accomplish to

address this problem? To address this

problem, you must accomplish the following:

Actions Compliance times Procedures

(1) Measure the drive belt tension. The difference should be a minimum of 6 millimeters

(mm) (0.236 inches (in)) and should not exceed 11 mm (0.433 in).

Within the next 25 hours time-in-service (TIS)

or 90 days after November 27, 2000, (the

effective date of this AD),whichever comes

first.

Follow the procedures in DG Flugzeugbau

Technical Note (TN) 873/16, dated October

25, 1999, and the Maintenance Manual for

DG–800B.

(2) If you find improper tension as specified in

this AD, accomplish the following:.

Before operating the sailplane.

(i) Lower the tension if it is too high. Check the

position of the propeller in relation to the engine compression point to assure it is within

limits, and adjust if necessary.

(ii) If you have to reduce the drive belt tension,

execute a ground test run. Check to assure

that the position of the propeller in relation to

the engine compression point has not

changed, and adjust as necessary. If this has

happened, the drive belt has slipped due to

too low tension.

(iii) Notify DG Flugzeugbau if tension problems

are still not resolved.

(e) Can I comply with this AD in any other

way? You may use an alternative method of

compliance or adjust the compliance time if:

(1) Your alternative method of compliance

provides an equivalent level of safety; and
