Pre-buy Helicopter and Engine Inspections

Making a bad acquisition can be costly. That’s why ETI offers Pre-Buy Inspection services to help you make the best decision and protect your investment.

When we perform a Pre-Buy Inspection, we visit the source, validate its condition, and evaluate its appraised value. We perform a thorough inspection which can include the disassembly and/or removal of parts blocking access to the completion of a detailed inspection.

When purchasing a Time-Continued serviceable engine, we highly recommend that you make the offer to purchase subject to an MRO Service Provider’s review. We can save you thousands of dollars in parts and rework replacements.


  • Pre-buy inspections available for a single module, engine, or a complete helicopter
  • Assessment for serviceability, current mod status and Commercial Engine Bulletins (CEBs)
  • Detailed report with clear findings
  • Possibility of referrals to companies with other capabilities, such as airframe
