Airworthiness Directives; Lockheed Model 382 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment supersedes an existing airworthiness directive 
(AD), applicable to certain Lockheed Model 382 series airplanes, that 
currently requires a revision to the Airplane Flight Manual to require 
takeoff operation in accordance with revised performance data. That AD 
also requires installation of certain valve housings for the propeller 
governor on the outboard engines. This amendment revises the 
applicability of the existing AD to remove certain airplanes. This 
amendment also revises references to a certain replacement part number 
of a valve housing. The actions specified by this AD are intended to 
ensure that the airplane maintains adequate thrust decay 
characteristics in the event of critical engine failure during takeoff.

DATES: Effective April 4, 1997.
    The incorporation by reference of Lockheed Airplane Flight Manual 
Supplement 382-16, dated August 11, 1993, as listed in the regulations, 
was approved previously by the Director of the Federal Register as of 
August 10, 1994 (59 FR 35236, July 11, 1994).

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

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) by superseding AD 95-12-05, 
amendment 39-9255 (60 FR 28715, June 2, 1995), which is applicable to 
certain Lockheed Model 382 series airplanes, was published in the 
Federal Register on February 21, 1996 (61 FR 6579). The action proposed 
to supersede AD 95-12-05 to continue to require the previous revision 
to the Airplane Flight Manual to require takeoff operation in 
accordance with revised performance data. The action also proposed to 
continue to require the installation of certain valve housings for the 
propeller governor on the outboard engines. The action also proposed to 
revise the applicability of the existing AD to remove certain 
airplanes, and to revise references to a certain replacement part 
number of a valve housing.
    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.

Support for the Proposal

    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 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 proposed AD.
    The actions that are currently required by AD 95-12-05 take 
approximately 8 work hours per airplane to accomplish, at an average 
labor rate of $60 per work hour. Required parts cost approximately 
$90,000 per airplane. Based on these figures, the cost impact on U.S. 
operators of the actions currently required is estimated to be 
$1,628,640, or $90,480 per airplane.
    Since this new AD only revises certain information and part 
numbers, it will impose no new costs to the affected operators.
    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 will accomplish those actions in the 
future if this AD were not adopted. However, the FAA has been advised 
that the only U.S. operator of the affected Lockheed Model 382 series 
airplanes has already equipped half of its fleet (9 airplanes) with the 
valve housing assembly that is required by this AD. Therefore, the 
future economic cost of this AD on U.S. operators is now only $814,320.

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)

[[Page 9076]]

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 removing amendment 39-9255 (60 FR 
28715, June 2, 1995), and by adding a new airworthiness directive (AD), 
amendment 39-9951, to read as follows:

97-05-07  Lockheed: Amendment 39-9951. Docket 96-NM-35-AD. 
Supersedes AD 95-12-05, Amendment 39-9255.

    Applicability: Model 382, 382E, and 382G series airplanes; 
equipped with a servo-type valve housing assembly having part number 
714325-3 or -7 installed on any outboard engine; certificated in any 
category.

    Note 1: This AD applies to each airplane identified in the 
preceding applicability provision, regardless of whether it has been 
otherwise 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 that the airplane maintains adequate thrust decay 
characteristics in the event of critical engine failure during 
takeoff, accomplish the following:
    (a) Within 60 days after August 10, 1994 (the effective date of 
AD 94-14-09, amendment 39-8961), revise the Limitations and 
Performance Data Sections of the FAA-approved Airplane Flight Manual 
(AFM) to include information specified in Lockheed Airplane Flight 
Manual Supplement 382-16, dated August 11, 1993, and operate the 
airplane accordingly thereafter. The requirements of this paragraph 
may be accomplished by inserting AFM Supplement 382-16 into the AFM.
    (b) Within 12 months after the effective date of this AD, 
replace the servo-type valve housing assemblies having part number 
714325-3 or -7 with a governor assembly control number 577888 on the 
propeller governors installed on the outboard engines, in accordance 
with Lockheed Document SMP-515C, Card No. CO-135. Replacement of 
these assemblies with governor assembly control numbers 577888, 
constitutes terminating action for the requirements of paragraph (a) 
of this AD; once the replacement is accomplished, the AFM revision 
may be removed.

    Note 2: Propeller governors with servo-type valve housing 
assemblies having part number 714325-3 or -7 may be retained or 
replaced with a governor assembly control number 577888 for use on 
the inboard engine positions.

    (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, 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 3: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the Atlanta ACO.

    (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 AFM revision shall be done in accordance with Lockheed 
Airplane Flight Manual Supplement 382-16, dated August 11, 1993. 
This incorporation by reference was approved previously by the 
Director of the Federal Register in accordance with 5 U.S.C. 552(a) 
and 1 CFR part 51 as of August 10, 1994 (59 FR 35236, July 11, 
1994). 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 
inspected at the FAA, Transport Airplane Directorate, 1601 Lind 
Avenue, SW., Renton, Washington; or at the FAA, Atlanta Aircraft 
Certification Office, Small Airplane Directorate, Campus Building, 
1701 Columbia Avenue, Suite 2-160, College Park, Georgia; or at the 
Office of the Federal Register, 800 North Capitol Street, NW., suite 
700, Washington, DC.
    (f) This amendment becomes effective on April 4, 1997.

    Issued in Renton, Washington, on February 21, 1997.
