Since the engine mount bolts for a DC-10, there's a very interesting documentary DVD from A&E channel online which is about the crash of flight 191 (AA DC-10) which was by the engine mounts damage due to the use of forklifts and shift change (workers went onto lunch with only the front bolt installed, the forklift hyd leaked slowly and let the rear mount push up on the structure damaging it, workers didn't know that and put the rear mounting bolt in)

If I remember right there is 6 bolts that mount the engine to the pylon. Two on the forward mount and 4 on the rear mount. It has been along time since I worked on a flyable DC-10. We sent ours out to the boneyards 3 years ago. And the last time I worked on a DC-10 it was being cut up for beer cans.

The CF6-6 (DC10-10) used 6, the early CF6-50 (DC10-30) used 6, later -50's used 8. The extra bolts were due to a "5 piece" FWD engine mount; the earlier versions were a "single piece" mount. AFIK the change was to seperate the jobs for the mounts: Thrust=FWD, Torque=AFT. I assume that the previous design shared the loads.
