## Summary

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Airbus Model A300 B2 and B4 series airplanes. The existing AD currently requires modifying the wiring of the autopilot pitch torque limiter switch. This proposed AD would add repetitive operational tests of the autopilot disconnection upon pitch override, and related investigative/corrective actions if necessary. This proposed AD results from the determination that such operational tests are necessary following the modification. 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.
