Aircraft Financing Considerations

What Lenders Look For

  • Diesel variant (Jet-A) has limited service network in US—verify support
  • Multi-engine rating required
  • Composite pre-buy critical
  • Insurance moderate for modern twin

A thorough pre-buy inspection is essential before purchasing any aircraft. For the Diamond DA42 Twin Star, pay special attention to:

  • Diesel engine service (if AE300)
  • Composite skin condition
  • Both engine times and condition
  • Gear actuators
  • G1000 currency
