Airworthiness Directives; Bombardier, Inc., Airplanes

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model DHC-8-401 and DHC-8-402 airplanes. This proposed AD was prompted by a report that a pilot was unable to move the rudder pedal due to an obstruction. This proposed AD would require an inspection to determine if wiring shrouds are present, and modifying the wiring shrouds if necessary. We are proposing this AD to address the unsafe condition on these products.
