DFW Aero Mechanix Policies:
The prepurchase inspection is often misunderstood. It is not a way to ensure that there is nothing about to break on the airplane, and it carries no warranty with it. We sit down with you and agree in advance a scope of work. There is no single blanked document that constitutes an acceptable prepurchase scope of work. Depending on the buyer, the aircraft, and the deal terms, the extent of a prepurchase inspection may vary widely. Normally a scope of work will address the following items:
- Logbooks, documentation, and maintenance records
- A.D. and service bulletin compliance review
- Engine visual inspection and compression check (piston)
- Engine borescope, cams, cylinders, valves
- Turbochargers, fuel systems, engine accessories
- Induction and exhaust systems
- Airframe visual inspection for corrosion, skin condition
- Inspect windshields and cabin glass for seals, crazing, scratches
- Fuel tanks, nacelle tanks, boost pumps
- Functional checks of major systems--pressurization, HVAC, electrical, hydraulic, landing gear, de-ice systems, etc.
- Other items as identified in the scope provided by the Buyer
It is customary for the purchaser to pay for the inspection. In any event, because airplane deals have been known to fall apart over details discovered during the prepurchase inspection, we require a clear understanding of who is liable for payment before we proceed.
For all aircraft to remain airworthy, the FAA requires they be inspected periodically. Most operators choose to comply with the inspections set forth by the manufacturer, but operators may choose to prepare and submit for FAA approval an alternate method of compliance.
Whatever the inspection, in most cases we can study the requirements and provide a flat-rate quote. However, that does not include fixing anything! Throughouot the inspection we itemize discrepancies--items found that have broken are no longer serviceable under the original specification. We bill on a time and materials basis for corrective actions to repair defects or replace unserviceable components.
In most cases we can provide estimates for a repair, but because the problem may lie deep inside a component, we cannot guaranty the final price. For example, you may have an air conditioning compressor that we think just needs freon. But once it's recharged, we may discover leaky lines or ducts, compressor problems, worn components, etc. Obviously, repairs for such problems are at extra cost.
Aircraft are complex and expensive. While we try our best to perfom required maintenance to the highest standards as quickly and efficiently as possible, be prepared for surprises!
If you are dissatisfied at any time with our work or you think our bill is unfair, please tell us and let us address your concerns!
