Whats really nice about this whole thing is that the lower cowling has to be lower which requires 2 AMT's to lower then one goes to the headset, and the other crawls into the lower cowling trying not to slip right out because of all the oil,that sit's in the lower cowl,and with this nifty wrench,rotates the valve shaft and right next to his face the starter engages and spins up to God knows what speed.Lord help the AMT if and when a starter blows up right next to his face.Every time I do this procedured I make sure somebody witness's this MPM procedure.For if it happens, I what a witness to the event.There is also very little room for the wrench to reach back between the engine casing and the valve's shaft.One tech crewchief and myself wonder why they don't they enlarge the door or redesign the wrench so that there is protection between you and the starter. I pray this will never happen to any line/overhaul AMT for I am sure a serious lawsuit will happen.767,777,737,757 do not use this procedure the cowling is always closed,with a large access panel/hole to activate the starter.
