If you can, get it!

I use it every day. Either working on an airplane, providing consultations to people (pre-buys, research, mechanical opinions), fixing the airplane that I am flying at that moment, working on the airplanes at the flight school I teach for when my flying is slow that day...

If you ever own an airplane, it's the best way to make it affordable. Sure, part 43 allows for some maintenance but the A&P can do almost anything. Except annuals and 337's (Yeah, yeah we know that's why we have IA's).

Here's the warning/ disclaimer: It's the hardest certificate I have earned yet. Take months/ years to be eligible. Not as easy as attending ATP for three weeks and taking a written, oral and then practical. Three writtens then I had a two day oral and practical.
