Buying a Used Unknown 140

When buying a Unknown 140, the biggest value drivers are engine time since overhaul, maintenance-record completeness, damage history and avionics.

What to check before buying

  • Engine time to overhaul — hours and years remaining drive price more than total airframe time.
  • Logbook completeness — continuous, gap-free maintenance records protect value.
  • Damage history — any prior accident or incident; cross-check the registration against accident databases.
  • Avionics — a modern glass panel vs legacy steam gauges materially changes price.
  • Pre-buy inspection — always commission an independent inspection by a type-experienced mechanic before money changes hands.
