Airbus Airplanes
This AD applies to Airbus A300 B4-601, A300 B4-603, A300 B4-605R, A300 B4-620, A300 B4-622R, A300 F4-605R, A300 F4-622R, A310-203, A310-221, A310-222, A310-304, A310-322, A310-324, A310-325.
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 Airbus Model A300-600 and Model A310 series airplanes, that requires testing to verify if the smoke detection system can detect smoke within 60 seconds; and cleaning the installation and duct, if necessary. It also requires operators to submit a report of the test findings to the manufacturer. This amendment is prompted by a report that, during testing of the smoke detection system on in-service airplanes, the system failed to detect smoke within 60 seconds due to dust accumulation in the extraction ducts. The actions specified by this AD are intended to ensure that dust accumulation does not reduce the effectiveness of the smoke detection system and, consequently, lead to undetected smoke or fire in the lavatory of the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
