[Docket No. 98-NM-40-AD; Amendment 39-10534; AD 98-11-07]

Airworthiness Directives; Dornier Model 328-100 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to certain Dornier Model 328-100 series airplanes, that 
requires a one-time inspection of the double shuttle valve in the upper 
fuselage fairing for incorrectly labeled part numbers, and corrective 
actions, if necessary. This amendment is prompted by issuance of 
mandatory continuing airworthiness information by a foreign civil 
airworthiness authority. The actions specified by this AD are intended 
to ensure replacement of the double shuttle valves when they have 
reached their maximum life limit; incorrectly labeled part numbers of 
the double shuttle valves that are not replaced could result in the 
failure of the roll control spoilers, and, consequently, lead to 
reduced controllability of the airplane.

DATES: Effective June 25, 1998.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of June 25, 1998.

ADDRESSES: The service information referenced in this AD may be 
obtained from FAIRCHILD DORNIER, DORNIER Luftfahrt GmbH, P.O. Box 1103, 
D-82230 Wessling, Germany. This information may be examined at the 
Federal Aviation Administration (FAA), Transport Airplane Directorate, 
Rules Docket, 1601 Lind Avenue, SW., Renton, Washington; or at the 
Office of the Federal Register, 800 North Capitol Street, NW., suite 
700, Washington, DC.

FOR FURTHER INFORMATION CONTACT: Norman B. Martenson, Manager, 
International Branch, ANM-116, FAA, Transport Airplane Directorate,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to include an airworthiness 
directive (AD) that is applicable to certain Dornier Model 328-100 
series airplanes was published in the Federal Register on March 20, 
1998 (63 FR 13577). That action proposed to require a one-time 
inspection of the double shuttle valve in the upper fuselage fairing 
for incorrectly labeled part numbers, and corrective actions, if 
necessary.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were submitted in response 
to the proposal or the FAA's determination of the cost to the public.

Conclusion

    The FAA has determined that air safety and the public interest 
require the adoption of the rule as proposed.

Cost Impact

    The FAA estimates that 50 airplanes of U.S. registry will be 
affected by this AD. It will take approximately 1 work hour per 
airplane to accomplish the required inspection at an average labor rate 
of $60 per work hour. Based on this figure, the cost impact of the 
inspection required by this AD on U.S. operators is estimated to be 
$3,000, or $60 per airplane.
    The cost impact figure discussed above is based on assumptions that 
no operator has yet accomplished any of the requirements of this AD 
action, and that no operator would accomplish those actions in the 
future if this AD were not adopted.

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

[[Page 27835]]

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 final evaluation has been prepared for this action 
and it is contained in the Rules Docket. A copy of it may be obtained 
from the Rules Docket at the location provided under the caption

Adoption of the Amendment

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration amends part 39 of 
the Federal Aviation Regulations (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.


Sec. 39.13  [Amended]

    2. Section 39.13 is amended by adding the following new 
airworthiness directive:

98-11-07  Dornier Luftfahrt GmbH: Amendment 39-10534. Docket 98-NM-
40-AD.

    Applicability: Model 328-100 series airplanes, serial numbers 
3005 through 3086 inclusive; certificated in any category.

    Note 1: This AD applies to each airplane identified in the 
preceding applicability provision, regardless of whether it has been 
modified, altered, or repaired in the area subject to the 
requirements of this AD. For airplanes that have been modified, 
altered, or repaired so that the performance of the requirements of 
this AD is affected, the owner/operator must request approval for an 
alternative method of compliance in accordance with paragraph (c) of 
this AD. The request should include an assessment of the effect of 
the modification, alteration, or repair on the unsafe condition 
addressed by this AD; and, if the unsafe condition has not been 
eliminated, the request should include specific proposed actions to 
address it.

    Compliance: Required as indicated, unless accomplished 
previously.
    To ensure replacement of the double shuttle valves when they 
have reached their maximum life limit, accomplish the following:
    (a) Within 30 days after the effective date of this AD, perform 
a one-time visual inspection of the double shuttle valve in the 
upper fuselage fairing to determine if the part number of the valve 
is labeled correctly, in accordance with Dornier Service Bulletin 
SB-328-27-236, Revision 1, dated November 5, 1997.
    (b) If the inspection required by paragraph (a) of this AD 
reveals that the installed double shuttle valve is labeled 
incorrectly, prior to further flight, accomplish paragraphs (b)(1) 
and (b)(2) of this AD, in accordance with Dornier Service Bulletin 
SB-328-27-236, Revision 1, dated November 5, 1997.
    (1) Revise the valve identification label to correctly identify 
the part number of the double shuttle valve, and delete any 
reference to operating pressure (i.e., BAR 205).
    (2) Verify that the installed valve is within the limits 
specified for that particular part number in accordance with the 
service bulletin. If the installed double shuttle valve is outside 
the limits, prior to further flight, replace the double shuttle 
valve with a new part.
    (c) An alternative method of compliance or adjustment of the 
compliance time that provides an acceptable level of safety may be 
used if approved by the Manager, International Branch, ANM-116, FAA, 
Transport Airplane Directorate. Operators shall submit their 
requests through an appropriate FAA Principal Maintenance Inspector, 
who may add comments and then send it to the Manager, International 
Branch, ANM-116.

    Note 2: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the International Branch, ANM-116.

    (d) Special flight permits may be issued in accordance with 
sections 21.197 and 21.199 of the Federal Aviation Regulations (14 
CFR 21.197 and 21.199) to operate the airplane to a location where 
the requirements of this AD can be accomplished.
    (e) The actions shall be done in accordance with Dornier Service 
Bulletin SB-328-27-236, Revision 1, dated November 5, 1997. This 
incorporation by reference was approved by the Director of the 
Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 
51. Copies may be obtained from FAIRCHILD DORNIER, DORNIER Luftfahrt 
GmbH, P.O. Box 1103, D-82230 Wessling, Germany. Copies may be 
inspected at the FAA, Transport Airplane Directorate, 1601 Lind 
Avenue, SW., Renton, Washington; or at the Office of the Federal 
Register, 800 North Capitol Street, NW., suite 700, Washington, DC.

    Note 3: The subject of this AD is addressed in German 
airworthiness directive 1997-321/2, dated January 15, 1998.

    (f) This amendment becomes effective on June 25, 1998.

    Issued in Renton, Washington, on May 13, 1998.
