Pre-takeoff checklist
First, I'm new here...nice to meet all of you!
My flying career has been about begging, borrowing and renting aircraft for the last 25 years, but now I'm finally taking the plunge and shopping for my own. At my age (mid-50's), I want to buy my "forever airplane", get as proficient as I can in it, and live with it till I get too old to fly safely anymore.
Anyway, where I'm mostly stuck is budgeting for maintenance...totally clear on all the other costs of ownership, but the MX crapshoot scares me. A Cirrus owner friend has had the bad luck to have two $25K annuals in the last five years - he went into ownership thinking to spend $8-10K/year, so this hurts. I've researched, spoke to owners, mechanics, etc till my head hurts and I have to admit that it's probably not possible to predict MX cost on a particular used airplane with confidence.
Best idea I have so far relies on the Conklin & de Decker variable cost numbers so that I can say "type A is likely to be X% more/less than type B". I divide the hourly MX cost by the cruise speed of the airplane to get MX cost per NM so I can compare airplanes having different performance...here's what I get when I do this math for the aircraft I'm considering:
Of course, these are probably long-term average numbers that vary quite a bit year to year. My friend has his SR22 five years now, and his cost has been $25K, $8K, $4K, $25K, $8K - an average of $14K/year. This sequence has a standard deviation of about 9, suggesting that cost from $5K to $23K might be expected.
I'm sure if we looked at a handful of similar SR22's, the 5-year averages would be different - and this is my second question. If we were to take a group of similar aircraft (same make, model, equipment, age, condition, etc) under similar usage patterns (hours flown, pilot technique, maintenance philosophy, etc) and track MX cost over the long term, what do you think the variance would be...are they all roughly similar over a long interval, or would some just be inherently much more expensive than others - and if so, why?
Thanks in advance for any opinions!
