Airworthiness Directives; Stemme

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD) that

applies to certain Stemme GmbH & Co.

KG (Stemme) Models S10 and S10–V

sailplanes. This AD requires replacing

the fuel filter if it is contaminated,

inserting a revision to the Limitations

Section of the flight manual, and

inspecting the engine valve shafts for

brownish-black sticky residue. If a

residue is found on the valve shafts, this

action will require cleaning the engine.

This AD is the result of mandatory

continuing airworthiness information

(MCAI) issued by the airworthiness

authority for Germany. The actions

specified by this AD are intended to

prevent engine valve malfunction,

which could cause engine failure during

flight and loss of control of the

sailplane.

DATES: Effective July 17, 1998.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of July 17,

1998.

ADDRESSES: Service information that

applies to this AD may be obtained from

Stemme GmbH & Co. KG, Gustav-MeyerAllee 25, D–13355 Berlin, Federal

Republic of Germany. This information

may also be examined at the Federal

Aviation Administration (FAA), Central

SUPPLEMENTARY INFORMATION:

Events Leading to the Issuance of This

AD

A proposal to amend part 39 of the

Federal Aviation Regulations (14 CFR

part 39) to include an AD that would

apply to certain Stemme Models S10

and S10–V sailplanes was published in

the Federal Register as a notice of

proposed rulemaking (NPRM) on March

16, 1998 (63 FR 12706). The NPRM

proposed to require replacing the fuel

filter if contaminated, inserting a

revision to the Limitations Section of

the flight manual (FM), and inspecting

the engine valve shafts for brownishblack sticky residue. If a residue is

found on the valve shafts, the proposed

action would require cleaning the

engine. Accomplishment of the

proposed insertion, inspection, and

cleaning as specified in the NPRM

would be in accordance with Stemme

Service Bulletin No. A31–10–021, dated

June 28, 1995, and Limbach

Flugmotoren Technical Bulletin No. 47,

dated June 28, 1995.

The NPRM was the result of

mandatory continuing airworthiness

information (MCAI) issued by the

airworthiness authority for Germany.

Interested persons have been 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

After careful review of all available

information related to the subject

presented above, the FAA has

determined that air safety and the

public interest require the adoption of

the rule as proposed except for minor

editorial corrections. The FAA has

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.

Cost Impact

The FAA estimates that 9 sailplanes

in the U.S. registry will be affected by

this AD, that it will take approximately

5 workhours per sailplane to

accomplish this action, and that the

average labor rate is approximately $60

an hour. Parts cost approximately $30

per sailplane. Based on these figures,

the total cost impact of this AD on U.S.

operators is estimated to be $2,970, or

$330 per sailplane.

Compliance Time of This AD

The compliance time of this AD is

presented in calendar compliance time

instead of hours time-in-service (TIS)

because the average monthly usage of

the affected sailplanes varies throughout

the fleet. For example, one owner may

operate the sailplane 25 hours TIS in

one week, while another operator may

operate the sailplane 25 hours TIS in

one year. In order to assure that all of

the affected sailplanes are in

compliance within a reasonable amount

of time, the FAA has determined a

compliance time of 30 days after the

effective date of this AD to insert the FM

Limitations Section revision, and 60

days after the effective date of this AD

to replace the fuel filter and inspect the

engine is appropriate.

Regulatory Impact

The regulations adopted herein will

not have substantial direct effects 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, in

accordance with Executive Order 12612,

it is determined that this final rule does
30378 Federal Register / Vol. 63, No. 107 /Thursday, June 4, 1998 /Rules and Regulations

not have sufficient federalism

implications to warrant the preparation

of a Federalism Assessment.

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 at the location provided

under the caption ADDRESSES.

applicable to Eurocopter France

(Formerly Aerospatiale, Society

any cracked transmission deck; and

replacement of the transmission deck

redesigned support beams. This

amendment is prompted by several

reports of cracks in the transmission

deck and support beams. The actions

specified by this AD are intended to

detect cracks that reduce the strength of
