And from the shop owner's perspective:
1. Insurance that runs approximately 10-15% of the shop gross, and will fight tooth and nail against paying any claim (in sharp contrast to flight school insurance, who wallpaper anyone who can spell "claim" correctly in cash and prizes)
2. A talent pool that is more akin to a crapped-in puddle, where a "green" A&P will actually remove value from the shop for their first 2-3 years of employ. Then once they get skills and are sufficiently non-lethal without constant supervision, they can bail to anywhere else for more $
3. The constant kvetching of aircraft owners who want all service on their handmade antique aircraft to be as simple, predictable and "rack rated" as their Honda Civic, which is itself nearing antique status
4. Shoddy parts vendors who barely honor their tiny warranty, leaving guess who to eat the labor for R&R/troubleshooting of the "new" or "overhauled" item that turned out to be trash.
5. FAA critters who obstruct every damned thing from their comfy chair, but still find time to sneak out of said chair and poke head into the hangar and threaten/complain/cheshire-cat-grin about some just-overdue calibration sticker or other minor paperwork shuffle like we were a baby-killing factory.
Add the aforementioned constant threat to livelihood and savings accounts should an incident occur, and, well... I wonder why more folks aren't diving into this pool
Both sides of this coin have long and valid complaints about one another. It's pretty intractable and I don't know the easy fix.
