Folks:

  

 I've read the posts on this subject and have to chime in.  I, like Doug, recently had an engine failure in flight.  Mine was in a Cessna 182.  Doug and I are part of the aviation community that realize that you are one or two aeronautical decisions away from being here to talk about an engine failure and being a statistic. 

  

 When it comes to aviation decision making, we make decisions on the ground when we maintain our aircraft and preflight them.  The decisions made on the ground impact those that you may have to make in the air.  However, once you are in the air, the outcome of those decisions is magnified significantly because you are now in a higher risk situation. 

  

 I can't see making the decision to put myself, as a father and husband, in an airplane that has had a known prop strike and go fly it.  Would you open the front case and bash the planetary gears with a hammer and then close it up and go fly?  Also, when looking at the Housai manual regarding prop strikes, remember the person who wrote it isn't the one sitting in the plane and flying it when the prop stops.  We can't take all of the risk out of what we do.  However, we can minimize risk by making approprate decisions. 

  

 We all have a budget for aviation.  Some are larger than others.  However, when it comes to safety of flight, I think we have to check our wallets at the door.  For me, I wouldn't want my wife or child finding out after an incident that I put money ahead of them possibly having a spouse or a dad.

 Here is my .02 cents worth.

  

 Doug, Craig, and others have perfectly good arguments and reasoning in  their views of prop strikes.  To be cautious is with out a doubt, is the  safest way.  However, the aviation community and companies over the years  have looked at prop strikes from a more what can only be called a more  "practical" view.  Yes "practical" is not always the safest. 

  

 The weight of one side against the other, usually comes to the bottom line.  $$$$$

  

 Considering just the dollar amount saved, is not conducive to safety, BUT  there should be a lot of engines sitting around with the mark of Cain on them,  that are still safe to fly, if that was the total answer.  While you might  not think much of Chinese engineering easement of prop strikes in their manual,  I submit you have nothing other, to prove your point.  Only what is the  safe thing to do.

  

 I can point to the engine I have on my airplane.  I bought it brand  new from AeroStar.  At 250 hours (more or less), I pulled the gear from  under my CJ.  (Doug Sapp was standing there so he'll remember my  "9-11")   The engine was stopping as she went on her belly  and broke off one blade.  Anyway we're in the middle of "no here".  A  old time local IA, checked the engine.  Did a run out check, and said she  was good to go.  I went, watching the chip detector with one eye and likely  landing spots with the other, all the way to AZ.  Nothing happened.   200 hours later, the chip detector came on.  It was nothing to do with  the prop strike, but the factory had put a scraper ring where an oil ring should  have gone!

  

 That same engine sits, on my airplane to this day.  I now have over  1,350 hours on it.  She still runs fine, but she is starting to show her  age.  

  

 Lucky? I guess so.  Smart?  I didn't really have a choice money  wise at that point.  Practical?  Yes, but I had lots of advice in  making that decision. 

  

 Then, as now, we do not have M-14p nor HS6a overhaul shops to pick from  here in the US.  It's either its a new engine (no such thing in  HS6a).  It maybe an overhaul one from China, but everyone is dubious of  them.  The guy who dings a prop, is still stuck with that same  decision.

  

 Yes it is safe to say, get a new engine, and smart.  But wouldn't it  nice if someone out there could take a nose section off a "dinger", inspect it,  and give some guy a better way of making a decision?
