There was a similar topic 4 years ago about worst planes to fuel.. I've got kind of an open ended question like that - what's your favorite and least favorite planes that come on your ramp and why? To start, visually my favorite is a Falcon 50, can't beat that tri-engine look with the sleek, skinny fuselage. But I despise servicing them My favorite to work with is the Challenger 300.. Hands down very simple to service from the fuel, lav, and to tow. Tied with the Excel, those are just too easy to service, even the oil haha Least favorite goes to Challenger 600s and Lears..
