Airworthiness Directive · Amendment 39-8990 · Airbus Airplanes
Airbus Airplanes
This AD applies to Airbus A340-211, A340-311.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Industrie Model A340-211 and -311 series airplanes. This action requires modifying the bonding leads on the fuel quantity indicating (FQI) probes or the temperature sensor, on the fuel low pressure inlet pipe next to the compensator, and on the jet pump. This amendment is prompted by results of a quality survey, which revealed that there may be insufficient clearance between several bonding leads and certain FQI system probes or the temperature sensor, and between the bonding leads and the FQI probes and the compensator. The actions specified in this AD are intended to eliminate such insufficient clearance, which could lead to electrical arcing and a resultant fire in the event of a lightning strike.
