How this stacks up

• Listed 1 month ago

  On the market for a month or more — worth asking about negotiating room

• No damage reported

  The listing reports no prior damage — the seller's description, not the logbooks, so confirm it at a pre-buy

• 3/5 key specs

  Most key specs are provided; verify any missing details with the seller

This summary draws on signals shown in detail below — price comps, listing age, maintenance and engine status, and key specs. Read each section for full context. Not an appraisal.

Airframe time

Average over the aircraft's life — 6,474 hrs total time across ~53 years. A rule of thumb, not a guarantee.

High utilization

This airframe has averaged about 122 hrs/year over ~53 years — more than most personal aircraft. Regular flying keeps engines and systems healthy, but it also adds cumulative wear, so review the maintenance history, component overhauls, and how the total time compares with the type's typical service life.

Damage history

Reported in the listing — confirm against the airframe and engine logbooks.

This listing reports no prior damage. That is a positive sign, but the flag reflects the seller’s description, not the logbooks — confirm it during a pre-buy. Undocumented or unrepaired damage is a classic red flag, so have an independent inspector review the airframe and engine records before you commit.

Cost to own

Rule-of-thumb estimates — insurance ≈ 1% of price, hangar $7,500/yr, annual inspection $2,500/yr, fuel + oil at your selected hrs/yr. Your actual costs will vary.

At 100 hrs/yr, renting at $150/hr would be $7,790 cheaper annually — fly more to see ownership savings.

Buy-in is the asking price split evenly across partners — what you'd each pay to acquire the aircraft (the real figure is negotiated). Fixed costs (insurance, hangar, inspection) split equally by number of partners; fuel/oil is per-pilot since each partner flies their own hours.
