I worked on the civil version at the Best Ever Airline 100 & 200 series.
One of the overriding memory was it was the only aircraft that I have worked on where you had to lie on the floor, to release them hydrualic accumulator pressures, the put a 9 foot pair of steps in the left main gear bay climb up, & in my case stand on the handrails so I could open the panel & check the fluid level in the hydrualic tank!!
