McCauley hubs must be retired if any of the blades within the assembly are bent beyond repair limits inboard of the 85 percent blade radius. This condition, if not corrected, could result in crankshaft connecting rod journal fracture, which could result in total engine power loss, in-flight engine failure and possible forced landing. Aircraft was involved in a prop strike. How much more time before overhaul is remaining on the engine? Prior to any ground operation of the engine assure that the propeller flange and the crankshaft flange area are free of any crack indications in addition to the engine component inspection. documents in the last year, 41 from 54 agencies. continental prop strike ad continental prop strike ad.
