## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A300 B2 and B4 series airplanes. This proposed AD would require modifying the wiring of the autopilot pitch torque limiter switch. This proposed AD is prompted by several reports of pitch trim disconnect caused by insufficient length in the wiring to the pitch torque limiter lever. We are proposing this AD to prevent possible trim loss when the flightcrew tries to override the autopilot pitch control, which could result in uncontrolled flight of the airplane.
