Highest time aircraft ever...

[CrimsonEclipse]

High time Corporate aircraft are usually 12-20k (I rarely see above 12k)
They are designed with a 15-25k airframe life

Airline aircraft are usually designed with at LEAST 100k in mind.
the L1011 had a 250k design life.

The highest time beech 99 is N34AK at Ameriflight with 50700 and shes still going. I just flew her last week.

It would seem to me that some of the B-52's probably have quite a few hours on them. But who knows how you'd find out how many...it's probably classified.

I've heard that the B-52's and KC-135's are actually pretty low-hours aircraft, despite their age, and that re-engining proposals are usually stifled due to comparisons of cost vs. life remaining on the engines installed. The govt. can buy a lot of tax-free JP8 for the difference.

I used to fly N17334 (AA DC-3 Flagship Detroit) and remember it having ~48600hours in 1996, and Be-18T's with between 25000 & 30000 hrs.(a lot for GA aircraft).

That's right! I completely forgot about the unpressurized aircraft.
I remember a DC3 with over 90k....now I gotta look it up.

I believe one of PBA's former DC-3's had 82k when it was retired. One of the 3's I flew out of south Florida in the late 80's was around 78k when it was sold.

We have an F27 at Mountain Air with over 45000.

Correct, most of those B-52Hs spent their life sitting on alert.
There are probably still depots full of TF-33 engines already long paid for.
