A bit about me,

I work at a repair station (aircraft maintenance hangar). The company maintains aircraft leased by a customer - three Boeing 737-700.

I am not involved with the maintenance side, as I work for the ground services division. Cleaning, bag service and aircraft pushback are a few of the things I do.

Last night, our final flight of the night came in. As I directed the aircraft toward the end of the J line, I brought it to a slow halt. At this point, the pilot will typically cut power to engines and my teammates will then approach the landing gear and chock the wheels.

Twenty seconds after having set the parking brake, engines 1 and 2 are still running. I approach the pilot window and flash a thumbs-up, to which he replied by forming a "T", as in "time out", with his hands. This signified a need for ground power meaning that the APU -Auxiliary Power Unit, a smaller turbine engine on the rear of the aircraft- had failed.

I step underneath the jet bridge and prepare the cables for connection, keeping the running engine in mind. I turn on the power unit. I turn a 180 and start walking and stop dead in my tracks because I realise I am three feet away from the ingestion zone. Now, this puts me approximately 23 feet from the engine, but even at idle speed it is capable of sucking you in from 20 feet away. I actually managed to forget the engine was running! This happened because the sound of the engines had become background noise.

Finally, engines were both cut for a bit while an air start unit got the plane going again. After unloading the plane, we managed to push the plane out (with engine 1 running). Out of habit, I clear the flight deck to start engine 2, to which the pilot replies, "you don't want me to do that - I'll push you right through the terminal". A slight error on my part!

Anyway, I didn't die. So that was nice. If you ever find yourself near a running aircraft engine, stay as far away as you can. Stay safe!
 
Actually, from one who is around aircraft a lot, running propellers can be even be more dangerous. When in motion, they are hard to see and there are many instances where people have walked right into them.
A few years ago, there was a mother with two small boys on the tarmac while I was warming up the plane. The kids were pinwheeling and running around checking out the different planes. One of the boys was running over to my plane and I immediately shut down with less than 20 feet between us. Boy, did I give that mother a piece of my mind. It literally scared the hell out of me as a nightmare almost came true. Be safe.

Absolutely, they're hard to see. I took a ground safety course while I was in A/P school and learned how dangerous recip/turboprop engines can be.
 
Here is a short video where a navy ground crew guy is sucked into a jet engine and lived. Incredible.


That's a video I saw during training. I also got to see pictures of those who didn't make it...
US Air. We worked at a small airfield dealing with DeHavilland Dash 8s and those were some BIG props!
Dash 8s are neat! Ever fly on one?

Well yes, that is nice. I am glad to hear it. We would have had to wonder what became of you, and I for one wouldn't have wondered that because it is worse than icky.

twinjet noodle casserole does not sound good at all.

I'm wondering: since you almost died / could have died, do you have to fill out Stupidity Paperwork, or do you just give yourself the serious talking-to and not have to worry about someone else feeling obligated to do it?

Well, nothing happened. Coworkers just laughed at my dumbness.

Cut my teeth working Dash 8's and Shorts 330's in Salisbury Maryland in the late 80's! Yeah....ingestion would not be a good way to go. All it takes is a moment's forgetfulness. If I remember correctly, a contract mechanic working on a Continental aircraft was lost that way a few years back. His hat blew off of his head and he took a step to retrieve it, and was gone. Yech.

Several times! I always found them to be more fun to fly on than jets. The only downside was getting seated next to the prop because being a high-winged beast, it spoiled the view! :unsure:

Yeah, I've seen that video - among others - as well. I was born on an Air force base, and spent the first 42 years of my life on them. I've seen more than one person eaten by propellers and jet engines - and helicopter tail rotors. Also watched many hats get sucked off people's heads, as well as a heavy tool box get hoovered up by an F-16. That was a real eye opener....:jawdrop::wideyed:
 
I have only flown on Dash 8 once. I was sitting perfectly visually aligned with the propeller so I could watch the prop pitch change. It was cool when they completely reversed the pitch to create reverse thrust when on landing roll.
For those who do not know what a Dash 8 here is photo. It is the largest prop jet in commercial passenger service as far as I know. Maybe the Russians have something larger. One thing that amazed me about the Dash 8 design is how little lifting wing surface it has compared to the size of the fuselage. Aviation Buff and pilot here so sorry if it is TMI.
