Airworthiness Directive · Amendment 39-17854 · Electrical power
Airbus Airplanes
This AD applies to Airbus Model A330-201, -202, -203, -223, -223F, -243, -243F, -301, -302, -303, -321, -322, -323, -341, -342, -343 airplanes; and A340-211, -212, -213, -311, -312, -313, -541, and -642 airplanes; certificated in any category; manufacturer serial numbers (MSNs) 1 through 1391 inclusive, except MSNs 0925 and 1382.
We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200, A330-200 Freighter, and A330-300 series airplanes; and Model A340-200, A340-300, A340-500, and A340-600 series airplanes. This AD was prompted by a non-connection of the constant speed motor/generator (CSM/G) during a final assembly operational test. This AD requires a detailed inspection of the connector wires for connector 1XE-A of the generator control unit (GCU)-CSM/ G for discrepancies (evidence of arcing or overheating damage), and related investigative and corrective actions if necessary. We are issuing this AD to detect and correct incorrect locking of contacts into connector 1XE-A of the GCU-CSM/G, which could result in a loss of contact continuity and lead to the CSM/G not operating, which, in conjunction with an emergency electrical configuration loss of the main electrical system or total engine flameout, could adversely affect the airplane's safe flight.
Within 1,000 flight hours after the effective date of this AD: Do a detailed inspection for discrepancies (proper engagement and evidence of arcing or overheating) of the affected connector wires of connector 1XE-A of the GCU-CSM/G, in accordance with Airbus Alert Operators Transmission A24L001-13, Revision 01, dated March 6, 2014. If any discrepancy is detected during the inspection, before further flight, do all applicable related investigative and corrective actions, in accordance with Airbus Alert Operators Transmission A24L001-13, Revision 01, dated March 6, 2014.
