S-76 Probe Points to Control Failure
S-76 operators inspected their aircraft after preliminary findings pointed toward a flight control failure in the Aug. 12 crash of a Bristow Group S-76+ that killed six people near Lagos, Nigeria. A Sept. 14 FAA emergency airworthiness directive ordered inspections with 5 hr time in service of main-rotor and tail-rotor servo input control pushrod assemblies on all S-76 models. The crash probe said the S-76 pitched up suddenly and rolled left “with varying attitude of yaw, roll and pitch for 12 seconds” before crashing.
