Capen" Subject: RV-List: Prop strike - by a hangar door Here's my scenario: We had a tornado at my local airport - looks like the sliding hangar door was pushed in to the prop (MT 3 blade Hydraulic CS) of my plane. It was in the hangar at the time - not running - just sitting there innocently in its chocks. The first look -see didn't reveal any obvious damage - closer inspection made a difference. I can see damage to the spinner and the lower two blades wobble not so nicely as compared to the rock solid top one. At a minimum, I'm thinking the prop gets rebuilt. I'm concerned about impact damage to the front of the engine. What could have been damaged? Would it be worth my while to have someone put a dial indicator to the prop flange? What would be your suggestion to determine if it needs to be torn apart and measured? I haven't tried rotating it through yet - in case I could make things worse. Full inspection tomorrow - this was just what came from the first look through. Your thoughts please, Ralph Capen 410-430-1344 ________________________________ Message 2 _____________________________________ Time: 03:27:10 PM PST US From: "n801bh@netzero.com" Subject: Re: RV-List: Prop strike - by a hangar door Pull the prop...

Your insurance should have no problem paying for the teardown and reassembly. There also is an AD requiring replacement of the crankshaft gear bolt on the back of the engine. These ADs exist because of engine failures after prop strikes. The old dial the crank flange and put a fresh prop on has proven to be NOT SAFE. Yes, you can ignore them with an "experimental" engine, but do you want to include a crank failure in your experiments?
