Pre Purchase Inspection

A pre-purchase inspection (PPI) for an aircraft is a comprehensive evaluation conducted before finalizing a sale to assess its condition, identify potential issues, and ensure it meets the buyer's expectations. The workscope of a PPI typically includes a thorough review of aircraft records, a physical inspection of the airframe, engines, and systems, and potentially a test flight. It also involves evaluating the aircraft's maintenance history, identifying any damage or wear, and assessing its overall airworthiness and value.

Here's a more detailed breakdown of the workscope:

1. Records and Documentation Review:

  • Logbooks: Reviewing maintenance logs, inspection records, and modification paperwork to verify compliance with regulations, ensure accurate maintenance history, and identify any discrepancies or missing records. 

  • Airworthiness Directives (ADs) and Service Bulletins (SBs): Verifying that all applicable ADs and SBs have been complied with. 

  • Modifications and STCs: Assessing any modifications or Supplemental Type Certificates (STCs) to ensure they are properly documented and approved. 

2. Physical Inspection

  • Airframe: Examining the structure for damage, corrosion, and previous repairs.

  • Engines: Assessing engine condition through compression checks, oil analysis, and potentially borescope inspections.

  • Avionics and Electrical Systems: Testing flight instruments, radios, navigation systems, and other onboard electronics.

  • Landing Gear: Checking for wear on tires, brakes, and hydraulic systems.

  • Fuel System: Inspecting for leaks and contamination.

  • Cabin and Interior: Evaluating the condition of seats, seatbelts, oxygen systems, and other safety features.

  • Control Surfaces: Inspecting wings, rudders, and elevators for damage and proper operation.

  • Exterior: Checking for damage, deformations, and other visible issues.
