Hi All,



Not quite ready to go over all the details yet, but my plane had a prop

strike on a taxiway light last week. One blade of the GSC wood prop lost the

inlaid plastic leading edge and had some slight damage (it will need to be

replaced). The engine (80 hp, 912UL) kept running and was shut down

immediately afterward.



Besides replacing the prop, what is the best course of action?



- Full tear down of engine?

- Tear down of gearbox only?

- No tear down necessary (wood prop, light damage)?

Hi Tim,



I'd recommend you contact one of the Rotax distributors for information regarding your prop strike. I've found Lockwood Aviation to be very helpful. 1-800-LA-ROTAX (1-800-527-6829) 



Regards,



Roy

Hello Tim



Read the service manual. I have manual for 914 and section 12.4.1 Check

after propellor ground contact or accidental propellor damage.



If you have a slipper clutch, and contact happened at low power setting,

if it were me, would probably just check crank and prop shaft for true,

and visual inspect gearbox and associated, put on new prop and go fly.



If no slipper clutch, follow manual, remove gearbox and send it out, check

crank for run out and inspect all.

That prop strike was a non-event.  It obviously is not the type of traditional prop strike that causes damage and that they talk about in the manuals.



You are much more likely to cause yourself problems by tearing down your engine needlessly.  The chances of damage being done to the engine by that strike are about zero, the chances of someone screwing up while tearing down and reassembling your engine are significant.    



In other words, leave it alone.  Being paranoid will just cause you more problems than it will ever solve.
