Props to the passenger on a Regional

Looks like maybe a landing gear failure - leadsing to a prop strike ??

Lucky gal!

If that happened to me, I don't think I would experience the proces of soiling my britches.... I think it would just materialize outside of my body- instantly. ... like "Scotty" beaming my poo somewhere, only quicker.

They should reinforce that portion of the plane in line with the props.
Maybe no windows there too.

What makes you think they don't?

Windows require reinforcement, props or not. A cylinder with a hole in it is A LOT weaker than a cylinder without one.

Put in enough reinforcement, and the useful load goes to zero.

It's possible to make a crash proof airplane. Just not one that can also fly.

If you want some real fun with props (or more accurately, fan and compressor/turbine blades, which serve the same purpose), look at the LAFD pictures of a 767 accident, and trace the trajectories of some of the engine pieces.

[For the record, there were no casualties in that accident, except for the airplane. It could have been a whole hell of a lot worse.]

The fact that she had the experience she did should illustrate how reinforced that area is! That's a lot of force in that propeller...
 
That reinforcement on the side of the fuselage is not for stopping a blade from coming through. It's a Kevlar reinforcement so the fuselage doesn't get beat to death while the props are shedding ice. Without that, the fuselage skin would take all the punishment.
We had the same kind of panels on our Aztecs and 401 and it would always startle the pax when some ice would hit the side of the fuselage and it sounded like someone was throwing rocks at us.

That Kevlar reinforcement also provides considerable stopping force to that blade even if that is not the design intent. It is pretty tough stuff, they even make high pressure, light weight, gas cylinders out of it.

An ungodly amount of force.. I am amazed it didn't go through and out the other side of the fuselage......

Lucky lady.... She needs to buy a few lottery tickets this week..

Exactly. It isn't designed to stop the prop, but it sure helps.
 
I still remember this accident in Minnesota.

Status: Final Date: Sunday 9 January 1983 Time: 19:41 Type: Convair CV-580-11-A Operator: Republic Airlines Registration: N8444H C/n / msn: 327A First flight: 1956 Total airframe hrs: 39511 Cycles: 64033 Crew: Fatalities: 0 / Occupants: 3 Passengers: Fatalities: 1 / Occupants: 30 Total: Fatalities: 1 / Occupants: 33 Airplane damage: Substantial Airplane fate: Repaired Location: Brainerd-Crow Wing County Airport, MN (BRD) (

United States of America) Phase: Landing (LDG) Nature: Domestic Scheduled Passenger Departure airport: Minneapolis-St. Paul International Airport, MN (MSP/KMSP), United States of America Destination airport: Brainerd-Crow Wing County Airport, MN (BRD/KBRD), United States of America Flightnumber: 927Narrative:
Republic Airlines Flight 927,carried out a nonprecision instrument approach to runway 23 at Brainerd-Crow Wing County Airport. The airplane touched down about 1,725 feet beyond the threshold of the 6,500-foot runway. The touchdown was made with the right wing down and with the right main gear about 37 feet from the right edge of the 150-foot-wide runway. The airplane continued to the right and the right propeller struck a 2- to 3-foot high snowbank which was located between the right edge of the runway and the runway edge lights. The No. 1 blade of the propeller separated and entered the cabin. One passenger was injured fatally and 1 passenger was injured seriously by the propeller blade. The weather was indefinite ceiling, 300 feet, sky obscured, 1 mile visibility,
with light snow showers and fog. The temperature was 32°F, and the winds were calm. The surface of the runway was ice and compacted snow. Just before the airplane landed, it was reported that there was 1 inch of snow and slush on the runway and that the runway braking taken from a ground vehicle was poor.

PROBABLE CAUSE: "The failure of the captain to properly align the airplane with the runway in sufficient time to allow a touchdown with no drift and the position of a snowbank on the edge of the runway the height of which exceeded that specified by regulation. Contributing to the accident were the intensity changes of the runway lights and the snow-covered terrain, both of which affected the captain's visual landing perception. The absence of a NOTAM on the control of the airport lighting system and failures of the airport management and the company station manager to report the location of the snowbanks to the flightcrew also contributed to the accident. "
 
In the military there are moor lines painted on the outside in inside of birds with props. On the inside there is a red line on the fuselage. At no time are you supposed to stand in the area while blades are turning.
 
"I went on a flight and all I got was this stupid propeller souvenir."

I would have taken it with me. :)
 
I know a person who was on the Scandinavian air crash that also had prop penetration. He was a little shaken up.

After this latest issue I don't think I will be climbing into one of these things.

I can see it now....


All airlines sell favorite seating with "upgrade pricing" attached... ie: window seats, emergency seats, first class seats...

Next we will see bargain prices for " Moor" seats...;)......:D....

Composite props on the Q400, I think. Not much inertia there compared to aluminum blades. And aluminum might just have bent and twisted rather than shatter.

Why? They are very safe aircraft, far safer than anything we fly. MD80s have had fan disks burst and penetrate the cowling, then go through the fuselage and kill the passengers. This has even happened on wing-mounted turbofans, although it's certainly more rare.
