Tri Jet Production

Tue May 15, 2018 10:20 am

Would anyone have a link to a video of the production of a tri jet? I'm very interested in the installation of the middle engine utilizing the S-duct?

This is a sped up video of one on the 727. There are attach points on the tail for hoisting the engine, pretty cool seeing it done in person. https://youtu.be/jbVX45lEK2Y?t=8m11s

Well, at least they didn't do it like American did with a fork lift.

We used a forklift on B727 engines all the time. Not an issue.

Sorry I was referring to the AA, DC10 accident at ORD where they used an unauthorized procedure to hang the engine with a fork lift.

I know what you were referring to, but that’s apples to broccoli. The AA (and Continental) procedures removed the engine and pylon as an assembly.

At PanAm we used a forklift to pull B727 & B747 engines.

Center engine changes were pretty simple on the B727. Access to the firewall connections were ridiculously easy as compared to the side engines.

Never changed a #2 on an L-1011, so I can’t really comment on it.

Here is a time-lapse video of the removal of the #2 (center) engine from a DC10 in what appears to be an airplane graveyard.
The plane is missing the #1 and #3 engines, and I assume has no ballast fuel in the tanks, so what is keeping the nose wheel on the ground?

Is just me, or is flying not as much fun anymore?

They probably have the nosewheel attached with a steel cable to a large concrete block or a ring embedded in the ground



I’ve seen FED EX do this while loading / unloading rather than use a tail stand

The Tristar Nbr 2 was similar to the DC10.
You needed a couple of technicians to do the clever parts, and about ten labourers to do all the heavy lifting.!!
I worked in BAH with Gulf Air and we changed Nbr 2 engines outdoors using the bootstrap chains. The hangar was not tall enough for a Tristar tail.
The engine stand was hoisted up to the engine on four chainhoists, then the engine was released from the airframe and the stand plus engine was lowered. The hoists were all manually operated, and the engine weighs 7 tonnes, and to keep it moving we had three men on each chain, taking turns to pull. After that you didn't need to visit the gym for a while!
The whole operation was pretty simple, just lots of heavy lifting. With a team that knew what to do, a remove/install took about 12 hours.

Number 2 on a DC-10/MD-11 must have been a real treat. That thing is up there!
