Airworthiness Directives; Alexander Schleicher GmbH & Co. 
Segelflugzeugbau Model ASH 25M Sailplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA adopts a new airworthiness directive (AD) for all 
Alexander Schleicher GmbH & Co. Segelflugzeugbau (Alexander Schleicher) 
Model ASH 25M sailplanes equipped with fuel injected engine IAE50R-AA. 
This AD requires you to inspect the fuel line for correct fittings, 
and, if any incorrect fitting is found, replace the fuel line. This AD 
is the result of mandatory continuing airworthiness information (MCAI) 
issued by the airworthiness authority for Germany. We are issuing this 
AD to

[[Page 29219]]

detect and correct any fuel lines with improper fittings, which could 
result in fuel leakage and a possible fire hazard.

DATES: This AD becomes effective on July 6, 2004.
    As of July 6, 2004, the Director of the Federal Register approved 
the incorporation by reference of certain publications listed in the 
regulation.

ADDRESSES: You may get the service information identified in this AD 
from Alexander Schleicher GmbH & Co. Segelflugzeugbau, D-36163

SUPPLEMENTARY INFORMATION:

Discussion

    What events have caused this AD? The Luftfahrt-Bundesamt (LBA), 
which is the airworthiness authority for Germany, recently notified FAA 
that an unsafe condition may exist on Alexander Schleicher sailplanes. 
The LBA reports that an incorrect fitting at one end of a fuel line was 
installed during production of the Model ASH 25M sailplane equipped 
with fuel injected engine IAE50R-AA. The incorrect fitting includes a 
combination of sealing cones. After maintenance, the incorrect 
combination of sealing cones inside the fittings might cause a fuel 
leak.
    What is the potential impact if FAA took no action? Any fuel line 
with improper fittings could result in fuel leakage and a possible fire 
hazard.
    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 all Alexander Schleicher Model ASH 
25M sailplanes equipped with fuel injected engine IAE50R-AA. This 
proposal was published in the Federal Register as a notice of proposed 
rulemaking (NPRM) on February 11, 2004 (69 FR 6585). The NPRM proposed 
to require you to inspect the fuel line for correct fittings, and, if 
any incorrect fitting is found, replace the fuel line.

Comments

    Was the public invited to comment? We provided the public the 
opportunity to participate in developing this AD. We received no 
comments on the proposal or on the determination of the cost to the 
public.

Conclusion

    What is FAA's final determination on this issue? We have carefully 
reviewed the available data and determined that air safety and the 
public interest require adopting the AD as proposed except for minor 
editorial corrections. We have determined that these minor corrections:

--Are consistent with the intent that was proposed in the NPRM for 
correcting the unsafe condition; and
--Do not add any additional burden upon the public than was already 
proposed in the NPRM.

Changes to 14 CFR Part 39--Effect on the AD

    How does the revision to 14 CFR part 39 affect this AD? On July 10, 
2002, the FAA published a new version of 14 CFR part 39 (67 FR 47997, 
July 22, 2002), which governs the 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 airplanes does this AD impact? We estimate that this AD 
affects 2 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 
inspection:

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

1 workhour at $65 per hour = $65...........  Not Applicable.........................          $65          $130
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to accomplish any necessary 
replacement that will be required based on the results of this 
inspection. We have no way of determining the number of sailplanes that 
may need this replacement:

----------------------------------------------------------------------------------------------------------------
                         Labor cost                                 Parts cost          Total cost per sailplane
----------------------------------------------------------------------------------------------------------------
1 workhour x $65 per hour = $65............................                     $160          $65 + $160 = $225
----------------------------------------------------------------------------------------------------------------

Regulatory Findings

    Will this AD impact various entities? We have 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.
    Will this AD involve a significant rule or regulatory action? 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); 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 AD 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 No. 2003-CE-64-AD'' in your request.
