RIN 2120-AA64
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

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
