Steve, Advanced Aircraft Service performed all of the annual inspections on the airplane from the time I purchased the airplane in 2017. If you were surprised that "one of the shops during the past annual inspections hadn't dealt with the corrected elevator and trim tab", then that is a failure of Advanced Aircraft Service.
I had no objection to compliance with that service bulletin as part of the 2020 annual, and approved an estimate of 9 hours for that work. I NEVER received any telephone calls from Dave Eddo about any cost overruns. If you provide me with an email address, I will send you a copy of the emails that he and I exchanged, most of which concerned the extraordinary delay in the completion of the work. None of them address any cost overruns because of corrosion that was discovered after work was begun.
The only email that I ever received from Dave Eddo concerning the installation of the windows was on September 28, 2020, in which he said "We are in the process of installing windows, waiting on exhaust system to be returned and waiting on some elevator skins and trim tab from Cessna."
I was NEVER informed that the labor estimate on the replacement of the side and rear windows would be exceeded by over 400%, to 37 hours.
Your statement, that Advanced Aircraft Service "had no choice but to address the problems", is very disappointing. Any repair facility always has the choice to identify problems, estimate the cost of correcting the problems, and then obtain the airplane owner's authorization to proceed with the work. The choice of whether to proceed with the work at that repair facility, based upon the estimate provided by that repair facility, always rests with the airplane owner.
I was "looking for" a reputable shop, with ethical business practices, that would prepare an accurate estimate of the cost of repairing the deficiencies it noted during the "inspection" portion of an annual inspection, and would obtain the airplane owner's authorization for the work to be performed. That was not my experience with Advanced Aircraft Service.
I would think that you, as a person in the airplane repair business, would be appalled by the conduct of Advanced Aircraft Service in this situation because of the damage is does to the airplane repair business and aviation in general.
My comment stands. Watch out for Advanced Aircraft Services. It feels no obligation to prepare accurate estimates upon which airplane owners can rely, it feels no obligation to inform airplane owners of any unforeseen work, and no obligation to obtain the airplane owner's authorization before proceeding with any extra work.
then proceed with the work after obtaining the airplane owner's authorization to proceed with the repairs
, 2018,
unfortunately, the statements made to you by Dave Eddo are false.
