Several years ago I decided it would be a good idea to send out postcards to all the 150-152 owners asking them to fill out a brief survey of their airplane purchase.
I haven't done this yet because of the logistics involved, but still plan too.
For starters, I intend to keep the survey annoymous, otherwise some folks are unlikely to be state the true purchase price because they used a lower figure for tax purposes.
Second, I'll need to figure out a fair way to evaluate the differences in condition, I'll probably use the standard 1-10 scale for exterior and interior condition, and then have a multiple choice format for avionics, grouped into high, medium, and low values. Then there's the issue of total time and SMOH, again, I'll probably set a series of ranges, its easy enough for the computer to calculate a dollar per hour average for each.
Lastly, I'll need to know the year and season the airplane was purchased.
If I can manage this survey, I'd plan to repeat it once a year. Then we would have a fairly accurate "Blue Book" of true C150-152 values.
I see this kind of data as very useful for club members selling their airplanes, and of course for buyers trying to determine if the asking price is fair.
It's a fairly large logistical challenge, I'd likely restrict the mailing to airplanes that have sold in the last 3-5 years, but that's still 8,000+ airplanes. At best I'd hope to get a 10% response.
Finally,
