REGULATORY TEXT:  
90-02-15 AIRBUS INDUSTRIE: Amendment 39-6477.

Applicability: Model A320 series airplanes, Serial Numbers 005 through 039, and 042 through 049, certificated in any category.

Compliance: Required within 60 days after the effective date of this AD, unless previously accomplished.

To prevent possible false electronic centralized aircraft monitor (ECAM) messages on Auxiliary Power Unit (APU) shutdown, accomplish the following:

A. Replace the standby transformer/rectifier (TR) with one identical to the main TR, and relocate it to a position with improved ventilation, in accordance with Airbus Industrie Service Bulletin No. A320-24-1028, dated July 7, 1989.

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 (39-6477, AD 90-02-15) becomes effective on February 20, 1990.
