Airworthiness Directive · Amendment 39-11109 · Bombardier Model DHC-8-100, -200, and - 300 Series Airplanes
Bombardier Model DHC-8-100, -200, and - 300 Series Airplanes
Superseded. A later AD replaced this one: AD 2007-01-11. Comply with the one in force.
Model DHC-8-100, -200, and -300 series airplanes having serial numbers 3 and subsequent; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model DHC-8-100, -200, and -300 series airplanes, that requires modification of the flight compartment door; repetitive inspections for wear of the flight compartment door hinges following modification; and repair or replacement of the hinges with new hinges, if necessary. This amendment is prompted by a report that the door lock mechanism of the flight compartment door jammed and could not be opened using the alternate release mechanism. The actions specified by this AD are intended to prevent failure of the alternate release mechanism of the flight compartment door, which could delay or impede the evacuation of the flightcrew during an emergency. Such failure also could result in the flightcrew not being able to assist passengers in the event of an emergency.
