If a mechanic warranties his work, and he has to go back into the tank because it still leaks, and he works on a different area of the tank, is that new work or warrantied work?
By your logic, my MX expects me to believe five FIVE leaks all began at the same time.
He said "It is fixed. Here is your invoice. The work is under warranty for a year."
When I asked him after the last time in the shop about the warranty, he himmed and hawd and said "We hadn't finished the repair but put it back in your hangar because you wanted to fly the plane.
Which 1. never happened and 2. if it wasn't completed why the invoice?
The guy thinks his **** doesn't stink. On day one I said "Is this something I need to take to the specialty folks in Austin?"
His response was "I have worked on every wet wing from a Mooney to a 737. Plus I own a Tiger. this is simple stuff."
After the 3rd time I said, Can I please give you the maintenance manuals that walk you through the repair and tank pressurization?
He said "Nah, Ive got this no need. Plus I have all the manuals downloaded as PDF if I need them."
After the 4th time I said are you pressurizing the tank?" "he said "I am not able to do that we will just fill it and watch it for leaks."
He is an over confident, shade tree mechanic that doesn't know when he is over his head. Probably a great engine guy.
In no other line of business does it work this way. If I had known this was costing me 1 dollar more than the original invoice, I would have flown it to Austin where they know how to do this.
He should have let me know that I was incurring costs.
He would say things like "One of your sumps was on the verge of having issues so I went ahead and popped in another one for you". It was cheap but it showed up on the bill.
Don't casually throw out "I went a head and did x for ya" Say "This looks bad, do you want me to order one and by the way the cost is X"
Bottom line is he thought he fixed it the first time. He didn't fix it and he talked his way into trying again and again until he got it and probably wishes he never said "warranty"
