Under what circumstances would you elect to use in-house maintenance personnel for scheduled and unscheduled aircraft inspections and contract with an FAA-approved overhaul and repair station for engine and airframe overhauls?

2. If a decision has been made to perform all aircraft maintenance (including engine and airframe overhauls) in-house, would you purchase or lease the special equipment needed to perform the required maintenance and overhauls? Explain your answer.
4. With regard to engine overhauls, would it be practical to enter an agreement with the engine manufacturer for a Power-By-The-Hour Program, or decide on a direct exchange for the engine or engine components when TBOs are reached?
