Background:

Several cases have been reported where a passenger door actuator detached from the passenger door, which allowed the door to drop in an uncontrolled manner.  This condition, if not corrected, could result in injury to personnel on the ground and damage to the aircraft.  Improvements are introduced to the passenger door actuator attachment to the aircraft and to the passenger door.
