DEPARTMENT OF TRANSPORTATION
14 CFR Part 39
[Docket No. 93-NM-220-AD; Amendment 39-8961; AD 94-14-09]
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 certain Lockheed Model 382 series airplanes, that
requires a revision to the Airplane Flight Manual to require takeoff
operation in accordance with revised performance data. This amendment
is prompted by a report of a change that had been incorporated into the
propeller governor of these airplanes during production, which altered
the thrust decay characteristic of the propeller when operating in an
engine failure scenario. The actions specified by this AD are intended
to ensure that the airplane is operated at sufficient speeds to
mitigate the problems associated with a faster thrust decay and to
prevent the airplane from departing the side of the runway.
DATES: Effective August 10, 1994.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of August 10, 1994.
ADDRESSES: The service information referenced in this AD may be
obtained from Lockheed Western Export Company, 2251 Lake Park Drive,
Smyrna, Georgia 30080. This information may be examined at the Federal
Aviation Administration (FAA), Transport Airplane Directorate, 1601
Lind Avenue SW., Renton, Washington; or at the FAA, Small Airplane
Directorate, Atlanta Aircraft Certification Office, 1669 Phoenix
Parkway, Suite 210C, Atlanta, Georgia; or at the Office of the Federal
Register, 800 North Capitol Street NW., suite 700, Washington, DC.
FOR FURTHER INFORMATION CONTACT: Thomas Peters, Aerospace Engineer,
Flight Test Branch, ACE-160A, FAA, Atlanta Aircraft Certification
Office, 1669 Phoenix Parkway, Suite 210C, Atlanta, Georgia 30349;
telephone (404) 991-3915; fax (404) 991-3606.
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 Lockheed Model 382 series
airplanes was published in the Federal Register on March 25, 1994 (59
FR 14124). That action proposed to require a revision to the FAA-
approved AFM to require takeoff operation of the airplane in accordance
with the revised performance data.
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.
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.
There are approximately 112 Model 382, 382E, and 382G 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 AFM change, and that the average labor rate is $55 per
work hour. Based on these figures, the total cost impact of the AD on
U.S. operators is estimated to be $990, or $55 per airplane.
The total 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.
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

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. App. 1354(a), 1421 and 1423; 49 U.S.C.
106(g); and 14 CFR 11.89.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding the following new
airworthiness directive:
94-14-09 Lockheed: Amendment 39-8961. Docket 93-NM-220-AD.
Applicability: Model 382, 382E, and 382G series airplanes;
equipped with a servo-type valve housing assembly, having part
number 714325-2, -3, -5, -6, or -7, installed on any outboard
engine; certificated in any category.
Compliance: Required as indicated, unless accomplished
previously.
To ensure that the airplane is operated at sufficient speeds to
mitigate the problems associated with a faster thrust decay and to
prevent the airplane from departing the side of the runway,
accomplish the following:
(a) Within 60 days after the effective date of this AD, revise
the Limitations and Performance Data Sections of the FAA-approved
Airplane Flight Manual (AFM) to include the 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) 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: 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
Secs. 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 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 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 Western Export Company,
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, 1669 Phoenix Parkway, Suite 210C, Atlanta, Georgia; or at
the Office of the Federal Register, 800 North Capitol Street NW.,
suite 700, Washington, DC.
(e) This amendment becomes effective on August 10, 1994.
Issued in Renton, Washington, on June 23, 1994.

Acting Manager, Transport Airplane Directorate, Aircraft Certification
Service.
