Flew the 32,33f,34,51 and 80.
Wonderful aircraft.there was a problem occasionally with clear ice on the top surface of the wing...generally after a long cruise with lots of fuel and a short turn around in humid conditions when clear ice would form on the top of the tanks.
Very difficult to see and our company painted black lines to aid mark one eyeball detection.
We had a fire in the overhead panel on a 51..emergency battery switch...but some very good work got it out and on the ground within 15 mins.
Pilots aircraft and great fun to fly.
Fokker 100 was a heap IMHO...never had problems with ice to my knowledge...but unsuited to European major airline and backward avionics as well as poor hold volume and low cruise speed due to thick wing. Then cockpit very noisy due to air con packs which also iced up and in or out airbrakes.
Very easy to fly
