In this scenario of liability, I really consider that the A&P Mechanic and the Shop Foreman are the two potentially legally liable for the aircraft damages, as well as the serious injuries that the pilot suffered in the accident.
According to the FAR 14 CFR §43.13(a), every person performing maintenance on an aircraft must be responsible to use the appropriate methods, techniques and practices, as well as the adequate tools and equipment in order to ensure that required work has followed the official instructions and has been completed satisfactorily (Hamilton, 2015, p. 111).
Furthermore, on one hand, the A&P certified Mechanic, did not follow the maintenance manual, and as a result, he replaced the engine cowling
