Annual Inspectionas

I've been looking at some information regarding the cost to maintain a 337. If you are an A&P mechanic and a 337 owner, how much are you saving by doing your own inspection and having an IA check your work?

A lot, probably at least 50% for me the last 20 years. Know your plane too

If I wasn't an A&P, I.A., I, personally, would not own any airplanes. Labor is the majority of the cost in airplane ownership. It took me 2 and a half years to get my P337H airworthy after sitting an extended period of time. $90,000.00 equivalent labor rate. For me, it was a retirement project after retiring from professional flying.

I recently met a fellow owner and he just paid $20k for an annual.
