My plane is down for annual, and I was supposed to be picking it up tomorrow... I get a call from my mechanic saying that they are having trouble getting the plane started. I immediately think this is weird, because my plane has ALWAYS been a super reliable starter - always firing up in 1-2 blades. He informs me that they are going to keep troubleshooting to figure out what the problem is. They eventually get it started, and I guess when when they test the left mag, it shudders/dies.
My mags are new with the engine, and only have ~200hrs on them. They have ALWAYS checked out perfectly for me, and I've never seen any sort sketchiness on either one... not to mention both were running perfectly when I dropped the plane off.
Is it possible that my mechanic messed up the left mag? He said that they had previously removed the battery box and left mag to adjust the timing... so my question is, would it be easy for him to bugger up the mag in the process of adjusting the timing?
At any rate, it is being sent out next week and checked out. Will the mag shop be able to determine why exactly it failed? If it's my mechanics fault, he'd be more than happy to cover the cost of this... but will they really be able to figure out WHY it has failed, and if it was his fault?
I knew this annual was going too smoothly...
