I'm too lazy to translate it myself, so here is the Google version  - There is a so-called inspection door that sits outside of the fuselage behind the left wing, said Lars Christoffersen, accident inspector from AIB to Nordvestnyt.dk

...

The door provides access to the aircraft's hydraulic system C, and the loss of the result, according to Lars Christoffersen, no danger to passengers.

- The door has a total of eight locks, so we have no idea how it could break loose, "says Lars Christoffersen Ritzau.

He describes the door weight as "not exceeding 20 kg." It was located behind the left wing, where - until it was turned into a free floating air missile - protected aircraft's hydraulic system for wind and weather.

Probably should clarify in thread title what type of door. I assumed a pax boarding door flew off in flight!
This would more appropriately be labeled an external access panel.

N722TW lost a hydraulic access door that roughly measures 4'x3'. That door weighs about 50 lbs. Wonder where they lost it?

Falling 4'000 meters? That's a speed of 900km/h when it reaches the ground! He's minimizing it a little... Better be somehwere safe!

It weighs more like 10 - if that - it is composite - not heavy - one person can install it.

It won't be falling that fast. It'll hit terminal velocity well before it reaches 900 km/h. I think it's somewhere around ~18 m/s using the 10 lb door. Even 20 kg it's only ~38 m/s, or 85 mph.

That being said I wouldn't want it to fall on my house, car or me!

If my complex calculations are correct if the door was doing "only" 85mph instead of 900km/hr when it hit me on the ground the result is likely to be the same......death. One death would simply be a fraction of a second slower than the other.

Don't forget ... this is a door .... a large squarish flat (or slightly curved) object.

It won't fall like a brick, more like a leaf.

Still wouldn't want to be under it, but I doubt it's going to plow into the ground like a meteorite ...

My first post in this forum.

The incident happened on 20 November this year where N722TW was flying DL118 (JFK to CPH). At the time of the incident the plane was descending towards CPH flying around 10000 feet. The plane landed safely in CPH and it was here the missing piece was discovered. The plane was flown back to JFK 2 days later as DL9934.

The Danish newspapers have written it happened on Friday, 3 December, which is incorrect.

Did the plane turn around or did it continue to NYC

Well, until it turns sideways. Then it'll drop like a rock.

It was JFK-CPH...

The pilot probably never even knew he lost it until after landing and ground staff asks what heppened.

It would be cool if it landed in your yard, although I suppose you'd have to give it back.

Nope. I am very familiar with the door in question, and it's curved to the shape of the fuselage. It'll tumble, but it won't stay sideways.

More like 5-10.

The first time it's strange, then you get accustomed to it.

What, we weren't talking about skydiving ? 

I was wondering how such a door could be that heavy, it doesn't hold pressure and as all things in a plane it has to be designed as light as possible.

Thats awfully heavy for an access door. They are usually composite these days and are very light (especially if 8 hartwell latches secure it)...an alloy over wing emergency exit is far more substantial and barely makes 50 lbs. It really is nothing more than a streamlining fairing. It would just flutter down to earth like a giant leaf.

Since they found the missing part, it's fairly easy to estimate the altitude from the location of the village in which the door landed. When passing X, the plane should be at Y feet.



Public service announcement: "It's" = "it is". To indicate posession, write "its." Looks wrong, but it's correct grammar

There are some reports saying the loss of the door resulted in a hydraulic problem which was shown to the pilots in the cockpit.
