NTSB Safety Rec’s Canadair CL-600-2B19
The National Transportation Safety Board recommends that the Federal Aviation Administration:
Require Bombardier to revise the maintenance procedures for the Canadair CL-600-2B19 so that the aileron freeplay check is accomplished at an appropriate interval that is less than 2,973 flight hours to prevent flight with aileron freeplay greater than the maximum limit. (A-05-21)
Require operators of the Canadair CL-600-2B19 to record and retain aileron freeplay check measurements and report the results to the manufacturer. (A-05-22)
Require Bombardier to develop and provide guidance to Canadair CL-600-2B19 operators that instructs flight crews in the proper recognition of and response to the effects of out-of-tolerance aileron power control unit output linkages. (A-05-23)
