Used Bonanza Buyer's Guide: Essential Inspection Checklist
Purchasing a used Bonanza is a significant investment requiring careful evaluation. From airframe condition to avionics systems to engine status, multiple factors affect aircraft value and safety. This comprehensive guide provides inspection procedures, red flags to avoid, and negotiation strategies for making informed purchasing decisions.
Model Selection & Year Considerations
Different Bonanza generations offer distinct advantages and considerations.
Bonanza Model Considerations
- Straight-tail (35/A36): More support options; excellent resale
- V-tail (33): Distinctive; fewer support options; check insurance availability
- Older models (pre-1980): Lower cost; potential avionics upgrade needs
- Modern models (2000+): Better systems; higher purchase cost; excellent support
- Best value range: 1990-2005 models balance cost with modern systems
Aircraft Value Assessment
Understanding fair market value prevents overpayment.
Value Resources
- Aircraft Bluebook Value: Professional valuation reference
- Recent sales: Compare similar recent transactions
- Total time: Major value determinant
- Engine time: Remaining hours before overhaul critical
- Avionics: Glass cockpit significant value add
Pre-Purchase Inspection Essentials
Professional inspection identifies potential problems before purchase.
Inspection Checklist
- Airframe inspection: Look for corrosion, cracks, damage history
- Engine borescope: Inspect internal cylinder condition
- Systems test: Verify all aircraft systems proper operation
- Avionics verification: Test glass cockpit systems and upgrades
- Records review: Comprehensive logbook and maintenance documentation
Red Flags & Issues to Avoid
Certain conditions should cause serious concern or walkaway decisions.
Critical Red Flags
- Accident history: Even repaired, accident aircraft carry risk
- Engine low on time to overhaul: Major future expense
- Corrosion evidence: Advanced corrosion requires expensive repairs
- Missing documentation: Incomplete records increase risk
- Avionics problems: Glass cockpit repairs expensive
Negotiation Strategy
Armed with inspection information, smart negotiation achieves best price.
Negotiation Tactics
- Use inspection results: Deferred maintenance justifies price reduction
- Comparable market data: Reference similar aircraft sales
- Walk-away price: Establish maximum and stick to it
- Contingencies: Make offer contingent on satisfactory inspection
- Closing timeline: Allow adequate time for due diligence
