Aircraft Pre-Purchase Inspection (PPI): The Essential Guide for Buyers

A pre-purchase inspection (PPI) is one of the most critical steps in aircraft acquisition. Whether you’re a first-time buyer or an experienced aviation professional, understanding the PPI process can save you significant time, money, and potential headaches down the road. This comprehensive guide breaks down everything you need to know about aircraft pre-purchase inspections.

What is a Pre-Purchase Inspection?

A pre-purchase inspection is a detailed evaluation of an aircraft’s condition before purchase. Think of it as a thorough medical checkup for the aircraft — examining everything from its mechanical systems to documentation history. Unlike annual inspections, PPIs are specifically designed to protect buyers by identifying current issues and potential future concerns.

• Provides leverage for price negotiations

Cost Protection

• Helps forecast future maintenance costs
• Protects your investment long-term
