89-23-04 AIRBUS INDUSTRIE: Amendment 39-6371. Docket No. 89-NM-92-AD.

Applicability: Models A300, A310, and A300-600 series airplanes, certificated in any category.

Compliance: Required within 30 days after the effective date of this AD, unless previously accomplished.

To prevent pitch trim runaway, accomplish the following:

A. Perform an inspection to determine if SAMM trim switches, Part Number BP 20- 455, Serial Numbers 110 to 923, inclusive, are fitted on the normal pitch trim electrical circuit, in accordance with All Operators Telex (AOT) 22/88/01, dated November 23, 1988. If any trim switch is determined to have any of these serial numbers, prior to further flight, replace the switch with a serviceable trim switch having a serial number 924 or higher, in accordance with Airplane Maintenance Manual (AMM) 22-27-12 (for Model A310 and A300-600 series airplanes) or AMM 27-11-11 (for Model A300 series airplanes), as appropriate.

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, Standardization Branch, ANM-113, FAA, Northwest Mountain Region.

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, Standardization Branch, ANM-113.

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 documents from the manufacturer may obtain copies upon request to Airbus Industrie, Airbus Support Division, Avenue Didier Daurat, 31700 Blagnac, France. These documents may be examined at the FAA, Northwest Mountain Region, Transport Airplane Directorate, 17900 Pacific Highway South, Seattle, Washington, or the Standardization Branch, 9010 East Marginal Way South, Seattle, Washington.

This amendment (39-6371, AD 89-23-04) becomes effective on December 1, 1989.
