REGULATORY TEXT:  
88-07-52 AEROSPATIALE: Amendment 39-5925. Applies to Model ATR-42-200 and -300 series airplanes, certificated in any category. Compliance required as indicated, unless previously accomplished.

To prevent erroneous fuel quantity readings in the fuel indication system, accomplish the following:

A. Within 7 days after the effective date of this AD, modify the cable in the fuel indicator panel, as follows:

1. Remove fuel quantity indicator 3 quart on the 4 VU panel (Ref: Airplane Maintenance Manual (AMM) 28-42-81-RAI 10000).

2. Disconnect cable 2842-0007 from plug 3 Qta pin R.

3. Insulate the cable from circuitry by means of heat shrinkable sleeve.

4. Attach cable to harness by suitable tie wrap.

5. Reinstall 3 Qta plug and 3 quart indicator (Ref: AMM 28-42-81-RAI 10000).

6. Perform a test of the fuel quantity indicator by pushing the test switch. Ensure that all digits indicate "eight," and that the "low level" lights illuminate.

B. Accomplishment of the modification of the cable in the fuel indicator panel and functional test in accordance with Aerospatiale Service Bulletin ATR42-28-0011, dated April 6, 1988, is considered an acceptable means of compliance with this AD.

C. 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 may add any comments and then send it to the Manager, Standardization Branch, ANM-113, FAA, Northwest Mountain Region.

D. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of the modifications required by this AD.

All persons affected by this directive who have not already received the appropriate service document from the manufacturer may obtain copies upon request to Aerospatiale, 316 Route de Bayonne, 31060 Toulouse, Cedex 03, France. This document may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or the Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington.
