REGULATORY TEXT:  
90-04-02 LOCKHEED AERONAUTICAL SYSTEMS COMPANY-GEORGIA: Amendment 39-6479, Docket No. 89-NM-281-AD.
Applicability: Model 382G series airplanes, Serial Numbers 5022, 5025, 5027, and 5029, certificated in any category.

Compliance: Required within the next 25 hours time-in-service after the effective date of this AD, unless previously accomplished.

To prevent the loss of the ability to extinguish a fire, accomplish the following:

A. Inspect all six wrenching surfaces (flats) on the hexagonal shaped part of the engine fire extinguisher system squibs to determine the part number and manufacturing date that is stamped on the wrenching surface, in accordance with Lockheed Alert Service Bulletin A382-26-7, dated November 4, 1989. Prior to further flight, remove all Whittaker Ordnance fire extinguisher squibs Part Number 4199-1 (Lockheed Part Number 695679-15) with manufacturing date 7/87, and install Whittaker Ordnance fire extinguisher squibs that do not have 7/87 stamped on the wrenching surfaces or other approved squibs.

WARNING: Observe all applicable safety precautions during the inspection. The fire extinguisher squibs are similar to a pistol cartridge. The squibs contain an explosive charge which could cause injury or death if accidentally fired. Do not expose squibs to heat, or an electric current, or strike or drop squibs.

B. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Atlanta Aircraft Certification Office, FAA, Small Airplane Directorate, Atlanta, Georgia.

NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector (PMI), who will either concur or comment, and then send it to the Manager, Atlanta Aircraft Certification Office.

C. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD.

All persons affected by this directive who have not already received the appropriate service information from the manufacturer may obtain copies upon request to Lockheed Aeronautical Systems Company, Field Service Office, 86 South Cobb Drive, Marietta, Georgia 30063. This information may be examined at the FAA, Northwest Mountain Region, Transport Airplane Directorate, 17900 Pacific Highway South, Seattle, Washington, or at the FAA, Small Airplane Directorate, Atlanta Aircraft Certification Office, 1669 Phoenix Parkway, Suite 210C, Atlanta, Georgia.

This amendment (39-6479, AD 90-04-02) becomes effective on February 26, 1990.
