Short answer: A pre-purchase inspection (pre-buy) for a large-cabin jet should combine a records audit, a manufacturer-recommended inspection package appropriate to the aircraft's age, engine borescopes and program reconciliation, a test flight, and a check of damage history against the physical aircraft. Scope it in writing before the aircraft is inducted, choose an independent facility the seller does not control, and agree in the LOI who pays for each class of discrepancy.
Scoping the inspection
- Base package: the manufacturer's recommended pre-purchase or equivalent calendar inspection for the model.
- Engines and APU: borescope inspections, trend data review and program statement reconciliation.
- Structure: corrosion inspection in known areas for the type and age.
- Systems: functional checks of avionics, pressurisation, landing gear and cabin systems.
- Test flight: with the buyer's representative on board.
- Paint and interior: a condition report even if not part of airworthiness.
Logbook and records audit checklist
- Continuous airframe, engine and APU logbooks since new
- Maintenance tracking report (for example CAMP) reconciled with the logbooks
- Airworthiness directives and service bulletin compliance
- Engine and APU program statements and transferability
- Damage history file with repair approvals
- Major modification approvals (STCs) and weight-and-balance records
- Export/import documentation if the aircraft has changed registry
