14 CFR Part 39

[Docket No. 94-NM-240-AD; Amendment 39-9255; AD 95-12-05]


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. This 
amendment requires installation of certain valve housings for the 
propeller governor on the outboard engines. 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 maintains adequate thrust decay 
characteristics in the event of critical engine failure during takeoff.

DATES: Effective July 3, 1995.
    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 
Docket, 1601 Lind Avenue SW., Renton, Washington; or at the FAA,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) by superseding AD 94-14-09, 
amendment 39-8961 (59 FR 35236, July 11, 1994), which is applicable to 
certain Lockheed Model 382 series airplanes, was published in the 
Federal Register on February 8, 1995 (60 FR 7480). The action proposed 
to require removal of any servo-type valve housing assembly, having 
part number 714325-2, -3, -5, -6, or -7, installed on any outboard 
engine, and replacement of those assemblies with part number 714325-1.
    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 8 work hours per airplane to 
accomplish the required actions, and that the average labor rate is $60 
per work hour. Required parts will cost approximately $90,000 per 
airplane. Based on these figures, the total cost impact of the AD on 
U.S. operators is estimated to be $1,628,640, or $90,480 per airplane.
    The FAA has been advised that the only U.S. operator of Lockheed 
Model 382 series airplanes has already equipped half of its fleet (9 
airplanes) with the valve housing assembly that will be required by 
this rule. Therefore, the future economic cost of this rule on U.S. 
operators is now only $814,320.
    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. 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 removing amendment 39-8961 (59 FR 
35236, July 11, 1994), and by adding a new airworthiness directive 
(AD), amendment 39-9255, to read as follows:

95-12-05  Lockheed: Amendment 39-9255. Docket 94-NM-240-AD. 
Supersedes AD 94-14-09, Amendment 39-8961.

    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.

    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 use the authority 
provided in paragraph (c) to request approval from the FAA. This 
approval may address either no action, if the current configuration 
eliminates the unsafe condition; or different actions necessary to 
address the unsafe [[Page 28716]] condition described in this AD. 
Such a request should include an assessment of the effect of the 
changed configuration on the unsafe condition addressed by this AD. 
In no case does the presence of any modification, alteration, or 
repair remove any airplane from the applicability of this AD.

    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 24 months after the effective date of this AD, 
replace the servo-type valve housing assemblies having part number 
714325-2, -3, -5, -6, or -7, with part number 714325-1, 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 part number 714325-1, 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 714325-2, -3, -5, -6, or -7, may be 
retained or replaced with part number 714325-1 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. The 
incorporation by reference of this document 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 July 3, 1995.

    Issued in Renton, Washington, on May 26, 1995.
