Plain English Summary

1/10 complexity

Mandatory inspection for Beagle B121 (Pup) aeroplanes fitted with the factory BE 10 dual-throttle modification: every 100 flight hours inspect the cable assembly linking left and right throttle levers for kinks, bends, or distortion/damage to the forward sliding end fitting. If any defect is found, the cable assembly must be replaced before further flight. This prevents throttle jamming or failure and loss of engine power control.
