The actions specified by this Directive are intended to prevent unintentional opening of the cabin side door and the utility door from the interior of the aircraft.

It requires them to check that the interior door handles on the cabin and utility doors are working correctly. Specifically, the door handles should **not** open the door when turned clockwise unless someone is also pressing the lock release button. If the door opens without pressing that button, the handle must be removed and reinstalled correctly following the manufacturer's instructions. This check must be done within 50 flight hours after 6 November 1997 (or when the handle is next removed, whichever comes first), and again whenever a door handle is removed in the future. The rule exists because the US aviation safety authority received reports of doors opening accidentally from inside the plane, which could distract the pilot and cause loss of control."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-50-33-interior-door-handles","history":"/api/acts/ad-beech-50-33-interior-door-handles/history","analysis":"/api/acts/ad-beech-50-33-interior-door-handles/analysis","conflicts":"/api/acts/ad-beech-50-33-interior-door-handles/conflicts","importantCases":"/api/acts/ad-beech-50-33-interior-door-handles/important-cases","documents":"/api/acts/ad-beech-50-33-interior-door-handles/documents"}}
