Any idea what I might do if a mechanic has done STC work on my plane and passes away before the sign off? Can another mechanic sign it off?
Thx

Of course, any AP can verify the work was done as per the STC and sign it off and any IA can approve it. Ideally, you would want an AP/IA.

Thx. Just wanted to make sure.

You're welcome. I've done and seen a lot of "installed by an unknown agency" log entries and 337s over the years.

Oh dear
