Concorde - Scrapped Due to Mech. Error?

Fri Mar 10, 2006 1:30 am

Hello to all. This is my first posting to this Forum. I have a friend who worked for R-R/British Aerospace during the development of Concorde and was aboard the test flights to monitor various electrical systems. He and I have been told that one of the Concorde aircraft was allegedly scrapped because maintenence personel introduced the 'wrong' (?) hydraulic fluid into the aircrafts hydraulic system.

I simply do not believe this claim to be true and have searched the Internet to no avail in my futile attempt to locate any report of such a bizarre and unrealistic event having ever occurred.

Has anyone heard this story which I suspect is little more than just that.

Thanks in advance, and my apologies for asking such a question, however I need some input from Aviation enthusiasts/observers to dismiss what appears to be a hoax designed to denigrate my freinds previous involvement with that extraordinary aircraft and/or the aircraft itself.

As far as I know, not one of the fleet was withdrawn for that reason.

An Air France aircraft was retired in 1982 after AF closed down a route and had surplus aircraft, with the airframe being scrapped in 1996. Other than the AF aircraft that crashed, every other airframe is accounted for.

Concorde - Scrapped Due to Mech. Error?

Fri Mar 10, 2006 1:47 am

In the British Airways fleet, a Concorde's hydraulic system was topped up with hydraulic oil from a 50 gal drum. The drum was kept under cover but otherwise in the open and rain water had pooled on the top of the drum and had contaminated the oil. This contaminated oil when put into the aircraft caused corrosion in some of the hydraulic system [especially if I remember correctly the engine intake system ] and this caused malfunctions to occur
The aircraft was withdrawn from service for I think a year and although it was almost brand new some consideration was given to scrapping it, however before that could happen the Concorde operation was changed and there was a need for the aircraft so it was repaired and returned to service until Concorde's retirement.
As you can imagine there were some major changes in the way hydraulic fluid was stored and away from base the Hyd system was normally topped up using quart cans so as to prevent any storing of unused oil which might have allowed water to be absorbed
By the way welcome to a. net

The incident happened. But the aircraft was not scrapped for that.

Air France Concorde F-BVFD was retired from service on May 27 1982. It was stored at CDG, used for spares and finally scrapped in November 1994.

The aircraft concerned was G-BOAG and if you go to this site you will get the details

You just beat me to it!!

I was about to say that OAG was for a while taken out of service before being returned to service with BA, being the first to be painted in the Landor livery. I was going to speculate that the reason stated above would be why she was temporarily withdrawn.

I've not read anything as to why OAG was taken out before now, so I thought it'd be best to do some research before posting, so I've been hunting through www.concordesst.com while VC10 was posting!!

EDIT: Just recovered.....

"Concorde 214 had a less than glamorous start to its life as G-BFKW. After manufacture and with no buyer, it was loaned via a sale or return agreement to British Airways, to cover for a 6 month period, while G-BOAC was being repaired at Filton.

After an aborted flight to New York on 26th April 1980 the aircraft was grounded with a water contaminated hydraulic system. the contamination had induced an intake ramp failure at Mach 2, which in turn lead to engine surges. The aircraft did not fly again for more than a year, but at a cost of one million pounds was re-entered into service, this time as G-BOAG, in Feb 1981.

With a lack of parts for it's Concorde fleet BA grounded and used "Alpha Golf" as it main spares source for a period of time up until 1984 when with parts availabe from the newly acquired G-BBDG. "G-BOAG" was returned to service and was the first to fly the the BA "Landor" livery in prepartation for the eventual floatation of British Airways on the London Stock Exchange."

The scrapped, or just withdrawn as it was then, AF A/C 211 provided many parts for OAG's return to service.

After OAG was back in the pack, with a now much more profitable, fully BA supported and expanding operation, the need for long term spares to support this tiny fleet, was helped by the purchase of A/C 202, G-BBDG, a BAe machine last flown 24 Dec 1981.
BA would go and have a hangar built at FZO to house 202.

I seem to recall that the scrapped AF Concorde was damaged following a tyre blow out, and that was the initial reason for it being grounded.

Nope, hard landing at DKR that damaged the tail and the repairs made the airframe heavier than the other a/c in the AF fleet.

We all thought that about 211.
But it seems not, a heavy landing in 1977 at Dakar, which was repaired, was 5 years before it was withdrawn.

In fact 211 went as in 1982, as AF terminated all scheduled services save the single daily JFK.

211 was due a big check, to save effort and money it was withdrawn, stories about it burning more fuel and handling becoming not so good, was nothing to do with the 5 year old repair work, simply that the aircraft needed the planned big input, which included a flight control re-rigging, which would improve handling and fuel burn.

BA's G-BOAD was the same in mid/late 2003, as an 'Inter Check' was nearly due, at least in regards to a higher fuel burn.
I don't think it had many cycles left before this, when it made it's last flight to JFK.

Wrong.
F-BTSC, c/n 203, was the one heavier than all the others, just like F-BTSD, (c/n 213) was lighter than all the others ( in AF's fleet).
That's why SD was always the one used for breaking speed records during world tours etc ....

Quoting GDB (Reply 10):

The incident occured in November 1977.
Operating AF085 CDG-DKR-GIG, F-BVFD was involved in this heavy landing at DKR with 14 feet per seconds at touch down (10 fps was considered as the standard limit).
The a/c was ferried back to CDG. Minor repairs were required and FD went back to service until 1982.

Another reason for F-BVFD retirement was that AF needed an aircraft for spares, as unlike BA, AF was not authorized (by the law) to use spares from one of the retired prototype or pre-serie aircraft.

You can now see G-BOAG at the Museum of Flight in Seattle.

Eight years ago I was working at CDG. For most of the day a BA Concorde was parked on stand. It turns out it was in town for a special charter. What started out as a little peak, turned into an hour long tour with many stories with a BA Engineer. One such story was AF had an a/c in the hangar on check. It had been jacked up and hydraulics were pressurized from a mule for some function, gear maybe. In a case of the l/h not knowing....... an avionic function required autopilot to be engaged. On engaging the a/p, it tried to steer in the direction that was commanded, not the same heading that it was facing in the hangar. It apparently jumped off the jacks and sustained enough 'retirement' damage to never fly again. Yes, seems a little far fetched and I have no proof to offer other than it came from an individual that had first hand access to all things Concorde.
