Consider it a lesson in why you should always, always read the manual: A Boeing 747 freighter aircraft got tail-happy in an unexpected way at Qatar's Doha International Airport, when a weight imbalance reportedly brought about by improper unloading procedures caused it to tip backwards onto its tail and thrust the nose of the jumbo jet into the air.

Yah there's also why weren't they unlocking and moving freight forward to adjust. Could of been snagged pallet and front kept offloading the front leaving the guys towards the rear in a predicament. Or some heavier machinery was loaded in the rear that loading they made sure a few pallets to offset loading the rear wouldn't tilt the plane. Should of been a warning from origin in that case. Looks like the tail stand might be standard for awhile :) Normally you get a good indication the plane is shifting exterior and interior. Evidently the guys inside were deaf and dumb because both wheeled loader operators should of been screaming.
You experts here have it all wrong. This is the new, “Top Secret “ 747 in Dump configuration mode. It’s used for passengers who need to rapidly de-plane to catch a connection. For cargo, you dump it right into waiting trucks.
well, yes, there is that small issue... (these are right up there with the MX reports. "humming from behind center pedestal" reply "people behind pedestal told to learn actual lyrics")
Well, it's not like the Iranians are going to get any parts to fix the thing from Boeing. Lucky for them it happened in Qatar. Qatar has a quality airport and they're equipped to handle this sort of stuff.
They don't like that , almost as stupid as the dreaded 737-900 ... that needs a fuel burn to reach a preferred altitude and a tail stick to unload PX ... " Oh wait we can't divert there, they don't have a tail stick" the 37.10 will be a nightmare as well
Indeed, this remind me an accident that happen some years ago, to an Emirates A330 (or may be A340) departing from LFPG. Same problem, incorrect loading that cause a premature rotation at take-off (and this was a flight with passengers). There is a very instructive report from BEA (Bureau Enquete Accident) about it.
To summarize: the origin of this incident was an incorrect value entered in the load calculation software, at the very first stage of flight preparation. This was because of a $10 keyboard has a defective "5" key… and no control of a valid value by the software.
If you wonder how a such error is possible, the report is still available here: https://www.bea.aero/fileadmin/documents/docspa/1997/a6-o970730a/pdf/a6-o970730a.pdf
Million dollar aircraft and still using membrane keyboards? I had to use a $9 (MSRP) keyboard at work (the Gray Lady of Silicon Valley) and came home to a electro-mechanical keyboard at home. My keyboard is still working. Wonder what happened to the Gray Lady!
Back in the late '80s my alarm company used to install an inexpensive alarm system who used membrane keypads. We replaced at least 1 keypad/control for a coustomer who used a pencil's eraser. He was unable to use his fingers like most people do.As of now I belive that alarm system is now 100% unreacheable.It was an ACE security control panel from Adcor Electronics. I still have the installers programmming manual. I think we added a hard buttoned keypad to do normal daily on/off security functions.
Didn't they have a tail steady [ tail jack ] ? Ar Auckland [ AKL ] when doing a turn around of a B747 Freighter the a/c handling crew always installed a tail steady. Signature required on our paperwork as well!
I was a 'loadmaster' for UPS Airlines for 8 years. I was expected to load/unload the 747 fast but always by the book. At airports where UPS had ground service vendors, if I witnessed something that could get me fired, I had to stop the vendor. Between a language barrier and being female, I did not always get cooperation, but I kept my job. Write-ups were time consuming but I was flying on that plane, so I was protecting my own a@@, as well. Loved our charters, got to see the world, loved the 747, DC-10, not so much. We rarely used the nose, mostly the side door.
I don't remember having loadmasters at UPS. I remember load supervisors but not "loadmasters". Of course that was 13 years ago.LOL I don't remember DC-10's either. Did you mean MD11?
Sorry, I did mean MD-11. But yes, I did not work for the package side of the business, I worked for the Airline. We were part of the charters for the military for the Civil Reserve Air Fleet (CRAF).
Do the load plan in the office,then you know what will & what will not be correct. CAL lost a 747 due to improper repair of a tail strike. weakened the pressure bulkhead. broke in flight & lost all
Don't want to sound like a conspiracy theorist here, but how often does that kind of incident occur? This is the only one they have, and getting replacement parts can be dicey with the sanctions. Was it accidental incompetence or deliberate?
I don't think this was a conspiracy issue here, and I very seriously doubt that it was anything else other than someone screwed up in the work force... (IE Tail Stand)... But I would rather see one laid pm it's tail due to bad loading vs one where it's load shifted in flight.... For those who do not remember the "Crash of Boeing 747 in Afghanistan caused by shifting cargo" where "The National Transportation Safety Board said an improperly secured vehicle in cargo rendered the huge aircraft uncontrollable in 2013 crash" - At least here no one got injured (Severely anyway) - I imagine the guy moving the load inside the plane got a bruise or 2.... A little bit of sheet metal work and this one is back working again... (God Bless Sheet Metal Mechanics)!
