Frequently Asked Questions

What Other Are Saying

We had an oil leak that was causing excessive oil loss.  After looking for it ourselves we decided to take it to a shop but they where unable to find the leak as well. 

They recommended we bring it to Mukenschnabl for them to take another look. Their knowledgeable staff was able to find the leak and fix our problem. 

We brought in the airplane to have it looked after.  They determined that the engine was tearing itself apart.  The mechanics took the engine out of the airplane and sent it to an engine overhaul shop.  After the engine was repaired they put it back in and reinstalled everything. 

They had no problem showing me the cause of the problem and letting me determine the course of action.  That really give me confidence in their work.   They suggested where to take the engine and handled the whole operation professionally. 

We had an accident and they had no problem coming out to help dissemble the plane so that we could ship it back home.  

We didn't hire them to fix the plane we only hired them to ship the plane home.  

In hindsight we where so impressed that we should have just hired them to fix the plane to begin with.
