The Complete Guide to Pre-Buy Aircraft Inspections
A thorough pre-buy inspection is one of the most critical steps in any aircraft acquisition. Learn what to expect, what to look for, and how to protect your investment before signing.
Why Pre-Buy Inspections Matter
Purchasing a business aircraft is one of the most significant capital decisions a corporation or high-net-worth individual can make. Unlike buying a car, aircraft transactions involve complex maintenance histories, airworthiness directives, and regulatory compliance requirements that can dramatically affect value and safety.
A comprehensive pre-buy inspection, conducted by an independent MRO (Maintenance, Repair & Overhaul) facility, is your single most important due-diligence tool.
What a Pre-Buy Inspection Covers
Airframe and Structural Integrity
Inspectors examine the fuselage, wings, and control surfaces for corrosion, fatigue cracks, and previous damage repairs. Any undisclosed structural repairs can signal hidden history and significantly impact resale value.
Powerplant and APU Review
Engine borescope inspections, trend data analysis, and hot section assessments provide insight into remaining engine life. Surprise engine overhauls can cost $500,000 to $2M+ per engine on large-cabin jets.
Avionics and Systems
A complete functional check of all avionics, autopilot, pressurization, and cabin systems is essential. Verify ADS-B Out compliance, CPDLC capability for transatlantic operations, and software currency.
Records Review
Logbooks, 8130 tags, major repair and alteration forms (FAA Form 337), and maintenance tracking software data must be scrutinized. Gaps in records are a red flag.
Choosing Your Inspection Facility
Select an independent MRO with no relationship to the seller or their maintenance provider. Type-specific experience matters — a shop that regularly works on Gulfstream G650s will catch issues that generalists might miss.
Budgeting for Inspection Costs
Pre-buy inspections typically cost $15,000–$75,000 depending on aircraft type, scope, and location. This is money well spent: a single undiscovered discrepancy can cost multiples of the inspection fee to remediate.
