Unsafe condition

This AD was prompted by reports of unexpected pitch upset upon autopilot disconnect. The FAA is issuing this AD to address an unexpected pitch upset occurrence when the autopilot is engaged while the airplane is in an out-of-trim condition and later disengaged. The unsafe condition, if not addressed, could result in high control column forces and difficulties in controlling the airplane.

Affected ADs

None.
