Check at annual

[FRED-E]

I was doing an annual on N12M (TSIO 360 C) today, removed the induction air filter to the turbo, Looking down into the box I saw something that didn,t look right, at the bottom of the box lay the alternate air door, it had detached from it's 2 attaching revits and was trying to go through the turbo. I have no idea how long it has been loose in there but not to long by the look of the scratches on the door where it hit the turbo inlet blades. Attached are a couple of pictures I took, hope this helps. I don't need to tell you what would have happened if that door had gone through the turbo.
Be sure to check yours at your next annual !!!!!!!!!!
