The latest issue of Airways magazine has an article on the beloved Beech 99. It has a pic of Ameriflights' N34AK, noting that it's the highest time BE-99 in the world, just under 50,000 hrs total.
I recently looked at the log for SkyWests' original EMB120, 186SW...it has in excess of 36,000 hours on it, still running strong. And back in the early 90s, I flew a BE-58 for USCheck that had 12,000+ hours on it. If any AirNet guys reading this get a chance to fly 1653W, I'd be curious to know how many hours it has on it now. It's gotta be well over 20K.
On the opposite end of the spectrum, on 3/31 I flew a bird that was delivered from Montreal on 3/27...it had 31 hrs total, 19 cycles on it. New car smell, and no filth/dustbunnies in the cockpit yet. That was pretty sweet, a rare treat for me.
