Airworthiness Directive · Amendment 39-12589 · Bombardier Model DHC-8-100, -200, and -300 Series Airplanes
Bombardier Model DHC-8-100, -200, and -300 Series Airplanes
Model DHC-8-102, -103, -106, -201, -202, -301, - 311, and -315 airplanes; certificated in any category; serial numbers 408, 413, 434 through 507 inclusive; excluding serial numbers 452, 464, 490, and 506.
This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model DHC-8-100, -200, and -300 series airplanes, that requires replacement of the observer's seat latch assembly with a new, improved seat latch assembly. This action is necessary to prevent the observer's seat from separating from its attachment points in the event of an accident or emergency landing, due to an understrength seat latch assembly. This action is intended to address the identified unsafe condition.
