Can a human get sucked into the jet engine of a normal modern airliner? if so has it ever happened and what is the minimum or maximum weight that these engines can suck? As a safety measure, wouldn't light weight but high strength retracting safety covers that cover engines when the aircraft is parked protect both humans, equipment and engines? Of-course it would have to take into account the need to minimize weight. Also it could have the option to be controlled by the ground team supervisor remotely as an extra safety measure.

    $\begingroup$ It's actually more than just weight. Surface area and density would also play a part. A 100kg lead brick might be safe at a given distance (from pull) whereas a 100kg human might not. A 100kg human might be safe at a given distance that a 100kg hang glider would not. $\endgroup$ Commented Dec 15, 2016 at 20:06

Yes. Human beings can get sucked into jet engines if they are close enough- this has happened multiple times in a number of aircraft ranging from A319 to A6E intruder.

However, it happens only in rare cases- usually in case of miscommunication or a mistake, when safety procedures are not followed. The following image shows the safety hazard area for aircraft engines.

In addition, the engines also have hazard-area warning decals on the nacelles to warn the ground personnel of the dangers.

As for the maximum weight that can be ingested, it will vary with the engines, though they have been known to ingest items from safety pylons to baggage containers, and of course people.

    $\begingroup$ True story: Boeing actually used a guy on a tether to collect the data to determine the radius of that safety arc, at least for the 737s. My father was the man on the tether. We used to have a video of it. $\endgroup$ Commented Dec 14, 2016 at 19:56

what is the minimum or maximum weight that these engines can suck?

Quite a lot, considering they can ingest ramp equipment...

    $\begingroup$ @DavidGrinberg considering some of the engine sizes on more modern jets, if this were to happen with a 777, 787, A380, or A350 then you would be looking at a shredded container and engine, not just a stuck container :) $\endgroup$

It's happened before, both with civilian and military aircraft.

This video was shot in 1991. Crews ready an A-6E attack aircraft for launch aboard Theodore Roosevelt (CVN-71) for a night sortie over Iraq during Operation Desert Storm when a fatigued green shirt walks in front of the port jet intake at full power. He is one of the few people who had this happen to them and live to tell the tale.

    $\begingroup$ The story was that his float coat, the life vest uniform that all flight deck hands wear, got snagged on an air date probe at the front of the intake duct, which prevented his body from being ingested into the compressor. Other parts of his kit came loose and were ingested into the engine as FOD, destroying it. He was very lucky, but got pretty badly banged up in the ordeal. $\endgroup$ Commented Dec 13, 2016 at 19:59

Yes. Here's an incident that happened at Mumbai (India) Airport in December 2015. A technician was sucked into the engine and killed.

A news report of the incident and AvHeald report for completeness


A Vacuum Cleaner for an Intake

The A7-E was notorious for swallowing people on the carrier deck. In the picture below the Yellow Shirt standing in front demonstrates how low and large the intake to the turbofan engine is. There was a lot of activity on the deck especially during launches and recovery, and it was easy to step in the wrong place. We were always cautioned, over and over again, be aware of the intake.

Luckily most of the time I was around the A7-E it was not turning. I would do my preflight at the start of the flight. At the end of the flight, with the engine shut down, I would come down off the ladder and do the post-flight. I turned and headed around the nose, and worked my way back and around the air frame.

A7-E on the Carrier Deck

Danger Areas for Suction, Exhaust, and Radiation

The danger areas are shown in the diagram below, where:

  1. Yellow is idle power
  2. Red is military power
  3. The pink is the radiation (radar operating) danger area

Notice that the suction danger area at idle power extends out to 15 feet.

Danger Areas: Suction, Exhaust, and Radiation

Hot Seat and a Close Call

As deployment neared the operations at the field shifted over to carrier qualifications. When arriving aboard the ship a pilot would have to qualify by performing a number of day and night landings. Each pass we made at the ship was graded. We started practicing at the field, and the schedule might use a procedure known as hot seating to maximize the number of pilots trained.

A pilot would start the aircraft and head for carrier landing practice. The aircraft had been previously fueled to keep us somewhere below our maximum landing weight. This was around 5,000 pounds. The pilot would finish the required number of approaches and on the way back to the squadron's apron hot fuel at the airfield fueling area. The term "hot fuel" was used to describe that the aircraft was turning while getting fuel. Once back at the squadron the crew would chock and tie down the aircraft. The pilot remained strapped in with the aircraft turning at idle.

The next pilot to fly would meet the aircraft as it came in, and do his preflight inspection, being careful to stay away from the danger areas. We would duck under the tail, and not cross close in front of the aircraft. When the next pilot was ready they came up beside the cockpit ladder and exchanged hand signs with the seated pilot. The pilots would exchange places.

The pilot finishing would then do their walk-around for the post-flight check. One night, after getting down off the ladder I did what I routinely do, which is head around the nose of the aircraft. It was dark on the tarmac, and I hadn't finished one step before I felt a hand grab me by the survival vest and pull me back hard, almost off my feet. I owe my life to that Maintenance Officer.

    $\begingroup$ Not exactly sure, but I would guess because the area shown is the max area subject to the catastrophic failure, and at idle the area will be smaller. Again, not sure why. $\endgroup$

Yes, humans can get sucked in. Yes, they have been sucked in. What can get sucked in is a factor of its size, surface area, and weight, (just like an airplane) but it really depends on the situation as to how an object comes to be ingested into such an engine. :-)


I remember somebody being sucked into an engine in 1989 with the accident involving United Airlines flight 811. The forward cargo door blew out, causing the cabin floor to cave in.https://en.wikipedia.org/wiki/United_Airlines_Flight_811 At least they found body parts in one of the engine - 9 people died in that incident. I remember it because it was en route from Hawaii to Auckland New Zealand (where I live) and a journey we had made several times.

Great answers already here, I'll just address the "minimum weight" part of the question.

There is no minimum weight. Foreign object damage is a very serious safety concern in aviation, because an engine can suck up pretty much any random object.

I've seen the crowd addressed en masse in air shows to please mind their garbage for the safety of the performers.
