Default Average lifespan of a business jet?

I have recently flown a 737 with over 74000 cycles.



Is taking off, flying up to altitude, then landing, one cycle?


10 Cycles Per Day (x) ...

10 years (3,650 days) = 36,500 cycles

20 years (x) ..10 c.p.d. = 73,000 cycles
25 years (x) ...8 c.p.d. = 73,000 cycles
40 years (x) ...5 c.p.d. = 73,000 cycles


How many cycles did the Aloha convertible have? IIRC it was something like
90,000 but a 737 might be designed to different life expectations
