January 1989 British Midland Airways 737, shut down wrong engine.

I'll take an engine failure in a twin jet over anything that has propellers, for the reason stated above; just fly it on speed.

How the heck did this become a Crash Talk thread?

Because most "Pressurized Twins" crash more easily than jets.

Because safety is a major consideration in the decision of which aircraft to buy if it carries 8 key employees of a company.

So when choosing between a King Air and Citation, the safety factor is relevant.

Good find.

I remember reading about this accident and had forgotten it involved a mistaken engine shutdown. What made the situation tricky was that they throttled back the wrong engine at the very same time the broken engine ceased making vibrations, so a false connection was made.

Once they shutdown the engine in the 737, can't they restart it if they so choose? Why is shutdown irrevocable?

The crew did attempt a restart of the engine they shutdown, so they must have thought it was possible.

The crew followed the procedures perfectly and ended up crashing. It is the reason why most operators now recommend V2 +10 or just keep what you have airspeed wise in the event of a failure at TO.

In the AA 191 event the engine departed the airframe because of a faulty MX procedure. The slat on that side retracted due to a loss of hyd pressure.

The crew being well trained and professional followed the procedure which called for a pitched up to and maintain V2. That wing with the retracted flap stalled and caused the crash.

Had the crew just held the AS they had they would have had a chance to fly it around and land.

After that the procedures were changed. Every event has the chance to helps improve safety. It is why things are always changing.

There are two ways to shut down the jet engines, pull the fire handle, which shuts off fuel, ignition , pneumatics ,hydraulics, and arms the fire bottles; and the second way is to place the start levers to the cut off position which shuts off fuel and ignition. Can't speak to the feasibility of restoring the fire handle on the 737.

In the Citations you have a fire button. Press it and it closes valves to shutoff fuel, hydraulics, etc. Press it again and the valves open and an engine restart can be attempted.

Because safety is a major consideration in the decision of which aircraft to buy if it carries 8 key employees of a company.

Engine restart is always an option in all of the jets I'm familiar with unless you have one of the following three Fs:
Fire
FOD
Frozen fan

That's because they are judged relative to their peers, King Airs against turboprops, Citations against jets.

Head to head, there is no contest, the Citation is much safer historically than a King Air.

Clint, like Paul said in some airplanes it’s a one time deal when you pull the fire handle. Same with disconnecting a generator you can only reset on the ground.

It’s is a nice feature on your plane that a restart is always an option.[/quote]

We had a new captain that got a tail pipe fire on an attempted engine start. He panicked and pulled the fire handle. The problem with that is the procedure for tail pipe fire is to bring the start lever to cut off, cutting off the fuel, and motor the engine with the start switch to blow out the fire, but pulling the fire handle cut off the air to the starter, so he had to call for the fire trucks. Oh, he also had to call the chief pilot.
