Plain English Summary

3/10 complexity

This mandatory airworthiness directive requires operators of certain Airbus A319/A320/A321 aircraft with IAE V2500 engines to update their Aircraft Flight Manual with a new emergency checklist. It addresses dangerous arcing at an Integrated Drive Generator connector that can cause cockpit display flicker, warnings, and risk of fire or power loss.

If display flicker occurs together with warnings affecting flight-data or autopilot systems, pilots must immediately switch off Generator 1 (GEN1).
