## Summary

We propose to adopt 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 proposed AD was prompted by the failure of the generator control unit-constant speed motor/generator (GCU-CSM/G) during a final assembly operational test. This proposed AD would require a detailed inspection of the connector wires for GCU-CSM/G connector 1XE-A for discrepancies (evidence of arcing or overheating damage), and related investigative and corrective actions if necessary. We are proposing 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 flame out, could adversely affect the airplane's safe flight.
