N601RX Posted October 31, 2011 Report Posted October 31, 2011 A teardown inspection runs around $7000 plus the prop assuming nothing else is wrong. Since the engine is only 50 SMOH most of the parts are going to be reused except the mandatory replacement items If you do it now the insurance company picks up the tab. If you fly it for a couple of years and something happens its on your checkbook. Remember the Lancair that lost the prop in flight around Hilton Head SC about a year ago and killed the jogger on the beach. The NTSB determined that the engine had been involved in a prop strike several years earlier and was returned to service without any log entry or teardown inspection. The prop strike started the crack and it spead around the crank until the end of the crank seperated at a later time.
jetdriven Posted October 31, 2011 Report Posted October 31, 2011 It could go either way. The engine is likely in pretty good shape from a "just overhauled" standpoint. Tearing it down and putting it back together may end up with who knows what. Ask them the main bearing or tappet clearances after they give it back to you. I bet they dont measure that. 1200 hours later, the engine is bad.

TonyPynes Posted November 1, 2011 Author Report Posted November 1, 2011 Any suggestions on who to send the engine out to for teardown and inspection?

N601RX Posted November 1, 2011 Report Posted November 1, 2011 These are 4 of the better ones on the east coast. There are no doubt others. In no particular order. A teardown inspection by any of these will look good in the logs and go a long way toward removing any percieved stigma associated with a prop strike. It will also minimumize the chance of having any of the previous problems you have had with your newly overhauled engine. www.Lycoming.com http://www.pennyanaero.com/ http://www.zephyrengines.com/homepage.html http://www.mattituck.com/
Piloto Posted November 1, 2011 Report Posted November 1, 2011 If you are trying to make the FBO responsible make sure you can prove that there was an actual prop strike at the location in question. In general taxiway maintenance is a responsibility of the city or county. FBOs are only responsible for their ramp space. The prop picture you posted does not show enough damage for a prop strike on concete or even on gravel surface. They may question your claim for an engine teardown when the prop does not show enough damage. José

Shadrach Posted November 1, 2011 Report Posted November 1, 2011 Tony, I think you've gotten ahead of yourself here. Your plane should have at least 8" of clearence. I did not see any mention of a ground scar. Pull the plane back to the hole and put the front tire in the hole and check for clearance. I find it hard to beleive that the tie-down holes are more than a few inches deep. So... 1) Either the hole is way deeper than it looks. 2) Your nose gear shock discs are shot and or the engine is drooping signicantly. 3) You did not really strike the ground, but rather picked up a stone at that or some other time during the operation. It is concievable that when you droped into the hole the reduced clearance caused you to pick up some FOD which blemished the prop. Verify that you had a strike before letting a shop tear into what might be a perfectly good engine and needlessly submitting the aviation economy to more liability related "make work"...
M016576 Posted November 1, 2011 Report Posted November 1, 2011 Quote: AustinPynes This past week I was taxiing from my hangar across the ramp area to the runup area. I felt my front end collapse and quickly shut down the plane and climbed out to see what happened. The good news is my nose gear didnt collapse but the bad news was the nose was sitting in a hole in the tarmac. I went and grabbed a lineman who helped me remove the nose from the hole. Truss looked fine. but the tips of the prop were scraped. I am thinking less than an 1/8 inch, maybe less than a 1/16th from my estimate on one corner of the prop tip. Lineman says the FBO dug holes and had tie downs embedded below the surface so snow scrapers didnt take them off. I saw two of them and was avoiding them and other taxiing planes but did not see the third tie down hole. While I dont remember an RPM dip or anything who knows. Two different mechanics are calling for teardown and inspection. So looks like I am in for a Teardown and Inspection of the engine, governor and prop overhaul possibly. All this on a 50 hour SMOH on engine and prop. Deep breath. Who would have thought holes in the ramp area. Be careful out there.
