REGULATORY TEXT:  
90-12-10 AIRBUS INDUSTRIE: Amendment 39-6624. Docket No. 90-NM-100-AD.

Applicability: Model A320 series airplanes, as listed in Airbus Industrie Service Bulletin A320-28-1024, Revision 1, dated February 20, 1990, certificated in any category.

Compliance: Required within 100 landings after the effective date of this AD, unless previously accomplished.

To ensure proper operation of the fuel quantity indicating system and to prevent the possibility of a spark in the fuel system in the event of a lightning strike, accomplish the following:

A. Verify the clearance between fuel probes 23QT1, 23QT2, and 28QT1, and the adjacent structures; install an insulating sleeve on the vent pipe bonding lead; and adjust fuel probe clearance, in accordance with Airbus Industrie Service Bulletin A320-28-1024, Revision 1, dated February 20, 1990, or All Operators' Telex (AOT) 28/89/03, dated November 20, 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 information from the manufacturer may obtain copies upon request to Airbus Industrie, Airbus Support Division, Avenue Didier Daurat, 31700 Blagnac, France. This information 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 (39-6624, AD 90-12-10) becomes effective on June 20, 1990.
