2. Flight 191 engine seperation was traced back to AA engine removal and re-install procedures, AA did not follow Douglass' recommended procedure (NTSB probable cause "improper maintenance"), hhmmm, seems like "one thing leads to another" thingy... and the deadliest US air crash
Yep that was the OFFICIAL RECORD of one incident. Now what never came to light was that the DC-10 had one main hydraulic tank. All backup systems used that hydraulic fluid. Back-up pumps were HYDRAULIC POWERED, not electric or engine driven. Once a major hydraulic line was servered, all fluid escaped and complete loss of flight control resulted.
After the ORD crash most pilots had that figured out, but the companies squashed all the info. they could.
It would not take a rocket scientist studying the crash to wonder why the airplane lost the left engine and the plane rolled into the lost engine.
That is normal if the engine is hanging on, but the weight loss would help a lot to stop such roll, and if normal aileron and rudder control was available, then such an accident would be an eye-opener but not result in a crash, providing competent pilots were at active controls.
(NOTE) Many RCers lose multi-engine models because they are not sitting in the cockpit when the yaw happens, thus they use aileron which is detrimental to the situation which requires rudder application.

Had the NTSB/FAA required that the DC-10 be retrofitted with both one-way check valves along double Hyd. lines and at least one additional Electric heavy duty hyd. pump and at least one aux. hyd.-fluid tank, then the Sioux City accident would have never happened. When #2 blew up it servered the hyd. line close to the engine and ALL hyd. fluid escaped. HYD. PUMPS WITHOUT HYD. FLUID JUST DON'T GOT NUSSIN' TO DOES!!!! [sm=angry.gif]
Even you people that believe government "Official Reports" should be able to figure that out. [sm=greedy.gif]
