Airworthiness Directive · Amendment 39-12620 · Bombardier Model DHC-8-100, -200, and -300 Series Airplanes
Bombardier Model DHC-8-100, -200, and -300 Series Airplanes
Model DHC-8-100, -200, and -300 series airplanes, serial numbers 003 to 563 inclusive, 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 repetitive inspections of the rudder pedal adjustment fittings for cracks and replacement of cracked fittings with new fittings. This amendment also provides an optional terminating action. This action is necessary to detect and correct cracking of the rudder pedal adjustment fittings, which could lead to deformation of the fittings, resulting in jammed rudder pedals and loss of rudder control, with consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
