Tips for Aircraft Owners in Illinois

✓Compare hangar rates across airports. Prices can vary 2-3x between airports in the same state. Smaller fields often have lower rates and shorter waitlists.
✓Check state sales/use tax on aircraft purchases. Some states exempt aircraft from sales tax or offer fly-away exemptions. Consult a local aviation attorney.
✓Consider a partnership. Splitting costs with 1-2 partners can cut your annual ownership cost by 50-65% while maintaining reasonable availability.
✓Budget for unscheduled maintenance. Plan for 15-25% above your expected annual maintenance costs. Older aircraft and complex airframes tend toward the higher end.
✓Get multiple insurance quotes. Premiums vary significantly between underwriters. Brokers like AOPA Insurance and Avemco can provide competitive options.
