DEPARTMENT OF TRANSPORTATION
14 CFR Part 39

[Docket No. 95-NM-248-AD; Amendment 39-9838; AD 96-24-14]
RIN 2120-AA64


Airworthiness Directives; Lockheed Model 382 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to all Lockheed Model 382 series airplanes, that requires 
that all landing gear brakes be inspected for wear and replaced if the 
wear limits prescribed in this AD are not met, and that the new landing 
gear brake wear limits be incorporated into the FAA-approved 
maintenance inspection program. This amendment is prompted by an 
accident in which a transport category airplane executed a rejected 
takeoff (RTO) and was unable to stop on the runway due to worn brakes; 
and the subsequent review of allowable brake wear limits for all 
transport category airplanes. The actions specified by this AD are 
intended to prevent loss of brake effectiveness during a high energy 
RTO.

DATES: Effective January 27, 1997. The incorporation by reference of 
certain publications listed in the regulations is approved by the 
Director of the Federal Register as of January 27, 1997.

ADDRESSES: The service information referenced in this AD may be 
obtained from Lockheed Aeronautical Systems Support Company (LASSC), 
Field Support Department, Dept. 693, Zone 0755, 2251 Lake Park Drive, 
Smyrna, Georgia 30080. 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 FAA, Small 
Airplane Directorate, Atlanta Aircraft Certification Office, Campus 
Building, 1701 Columbia Avenue, Suite 2-160, College Park, Georgia 
30337-2748; or at the Office of the Federal Register, 800 North Capitol 
Street, NW., suite 700, Washington, DC.

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 all Lockheed Model 382 series 
airplanes was published in the Federal Register on August 6, 1996 (61 
FR 40762). That action proposed to require (1) inspection of the main 
landing gear brakes, having part number 9560685, for wear, and 
replacement if the new wear limits are not met; and (2) incorporation 
of specified maximum wear limits into the FAA-approved maintenance 
inspection program.
    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. Due consideration has been given to 
the single comment received.
    The commenter supports the proposed rule.

Conclusion

    After careful review of the available data, including the comment 
noted above, the FAA has determined that air safety and the public 
interest require the adoption of the rule as proposed.

Cost Impact

    There are approximately 112 Lockheed Model 382 series airplanes of 
the affected design in the worldwide fleet. The FAA estimates that 18 
airplanes of U.S. registry will be affected by this AD, that it will 
take approximately 1 work hour per airplane to accomplish the required 
actions, and that the average labor rate is $60 per work hour. The cost 
of parts to accomplish the change (cost resulting from the requirement 
to change the brakes before they are worn to their previously approved 
limits for a one-time change) is estimated to be $4,800 per airplane. 
Based on these figures, the cost impact of the AD on U.S. operators is 
estimated to be $87,480, or $4,860 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 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 
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.

[[Page 66890]]

Sec. 39.13  [Amended]

    2. Section 39.13 is amended by adding the following new 
airworthiness directive:
96-24-14 LOCKHEED: Amendment 39-9838. Docket 95-NM-248-AD.
    Applicability: All Model 382 series airplanes, 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 (b) 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 loss of brake effectiveness during a high energy 
rejected takeoff (RTO), accomplish the following:
    (a) Within 180 days after the effective date of this AD, 
accomplish the requirements of paragraphs (a)(1) and (a)(2) of this 
AD.
    (1) Inspect the main landing gear brakes having the brake part 
number listed below for wear, in accordance with Hercules Alert 
Service Bulletin A382-32-47, dated March 1, 1995. Any brake worn 
more than the maximum wear limit specified below must be replaced, 
prior to further flight, with a brake within that limit, in 
accordance with the alert service bulletin.

    (2) Incorporate into the FAA-approved maintenance inspection 
program the maximum brake wear limits specified in paragraph (a)(1) 
of this AD.
    (b) 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, Atlanta Aircraft Certification 
Office (ACO), FAA, Small 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, Atlanta ACO.

    Note 2: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the Atlanta ACO.
    (c) 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.
    (d) The inspection shall be done in accordance with Hercules 
Alert Service Bulletin A382-32-47, dated March 1, 1995. 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 Lockheed Aeronautical Systems 
Support Company (LASSC), Field Support Department, Dept. 693, Zone 
0755, 2251 Lake Park Drive, Smyrna, Georgia 30080. Copies may be
