Federal Aviation Administration

14 CFR Part 39

[Docket No. 99-NM-219-AD; Amendment 39-11527; AD 2000-02-08]
RIN 2120-AA64


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, equipped 
with ground spoiler actuators having part number 1059A0000-02, that 
requires removal of the gland attachment bolts of the ground spoiler 
actuator and replacement with new bolts installed with higher torque. 
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 prevent hydraulic 
fluid leakage due to loose or broken gland attachment bolts, and 
consequent loss of the main hydraulic system.

DATES:  Effective March 2, 2000.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of March 2, 2000.

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, 
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425) 
227-2110; fax (425) 227-1149.

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 Dornier Model 328-100 series 
airplanes, equipped with ground spoiler actuators having part number 
1059A0000-02, was published in the Federal Register on November 26, 
1999 (64 FR 66422). That action proposed to require removal of the 
gland attachment bolts of the ground spoiler actuator and replacement 
with new bolts installed with higher torque.

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 12 airplanes of U.S. registry will be 
affected by this AD, that it will take approximately 2 work hours per 
airplane to accomplish the required replacement, and that the average 
labor rate is $60 per work hour. Required parts will be provided at no 
cost to the operator. Based on these figures, the cost impact of the AD 
on U.S. operators is estimated to be $1,440, or $120 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 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.
    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 
ADDRESSES.

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:

2000-02-08  DORNIER LUFTFAHRT GMBH: Amendment 39-11527. Docket 99-
NM-219-AD.

    Applicability: Model 328-100 series airplanes, equipped with 
ground spoiler actuators having part number 1059A0000-02, 
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 prevent hydraulic fluid leakage due to loose or broken gland 
attachment bolts, and consequent loss of the main hydraulic system, 
accomplish the following:

Replacement

    (a) Prior to the accumulation of 3,300 total flight hours, or 
within 330 flight hours after the effective date of this AD, 
whichever occurs later, remove the four gland attachment bolts of 
the ground spoiler actuator and replace with new bolts installed at 
a higher torque, in accordance with Dornier Service Bulletin SB-328-
27-289, dated March 3, 1999.

    Note 2:  Dornier Service Bulletin SB-328-27-289, dated March 3, 
1999, refers to Liebherr Service Bulletin 1059A-27-01, dated March 
5, 1999, as an additional source of service information for 
accomplishment of the replacement.

Spares

    (b) As of the effective date of this AD, no person shall 
install, on any airplane, a ground spoiler actuator having part 
number 1059A0000-02, unless it has been modified in accordance with 
Dornier Service Bulletin SB-328-27-289, dated March 3, 1999.

Alternative Methods of Compliance

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

Special Flight Permits

    (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.

Incorporation by Reference

    (e) The replacement shall be done in accordance with Dornier 
Service Bulletin SB-328-27-289, dated March 3, 1999. This
