TwoDeadDogs,
>> Legend has it that after an F50 suffered a gear collapse,a Fokker training guy pushed up on said beam whilst demonstrating to new trainees <<
You are wrong in this point. It was an engineer who pushed up, saying "I don't believe the required forces should be so light".
NOW he believes, but has no chance to ever push the beam up again. The required forces are said to be just a few (around 5 ) kilopond.
By the way, also the first collapse has been due to improper handling of (another)engineer.
Two damaged F 50 within a few days, two fired engineers, has been a sad statistics for the maintenance at Vienna.
