Report: El-Al Flight Dived Over London (1/10/06)

Thu Sep 28, 2006 5:24 am

An El Al flight carrying 450 passengers briefly went into a dive over London earlier this year, falling 2,800 feet (400 meters) after a glitch in its electronic landing system, authorities said Wednesday.

The airline's Boeing 747 was 10 miles (15 kilometers) east of London's Heathrow airport on Jan. 10 and flying on autopilot towards the airport when the aircraft began to descend from 4,000 feet (1,200 meters), according to a British aviation authority report.

An onboard system ordered the aircraft to continue descending and the plane fell on autopilot to a height of 1,200 feet (365 meters), the report said.

"The computer system recovered," a spokesman for the Department of Transport said while speaking on condition of anonymity in line with departmental policy.

Crew members noted the incident in a log but did not submit an incident report after arriving at Heathrow. Investigators did not find out until weeks later and posted their report on the Internet earlier this month.

Investigators concluded that the incident was caused by a failure of the plane's glidescope, part of a system which tracks flight path and angle of descent during landing, the spokesman said.

Authorities declined to specify the city from which the plane originated. El Al was not immediately available for comment.

Umm...just a guess...but probably Tel Aviv?  stirthepot 

Much like the BA 747 incident out of LAX, it sounds like the crew felt they had the situation under control and didn't want to make it a full blown "incident".

In this incident, the risk was minimal because visibility
below the 1,500 ft cloud base would have permitted the
flight crew to gain visual contact with terrain in good
time to avoid any Controlled Flight Into Terrain (CFIT)
hazard. Had the cloud base been lower, the aircraft’s
GPWS should also have provided a timely warning of
proximity to the ground.

El Al has a very small fleet (about 35 planes), but there are too often reports of serious incidents.

A 737 also "dived" just after it took off from Moscow a few months ago because of a malfunction in the auto pilot. The incident was described as very serious.
More recently, another 737 lost part of a wing while flying over Italy (it was an 80cm wide part according to the media reports).
And there were more reports of incidents over the last few years and months. There is obviously something going wrong.

Not necessarily, if it was one of their cargo craft...it could be making rounds around the EU picking up and dropping off...you're almost certainly right, but it's not 100%.  Smile

A cargo plane with 450 pax...?


But anyway, this incident seems to have been somehing really serious and thus frightening. I hope we'll know what happened, but that's far from certain.

A glitch like that is quite serious.

However, I have problems with the use of the word 'dove'....was it really a dive? Autopilots usually make the aircraftd descend, not dive. And airliners definitely don't 'fall' on autopilot as the article suggests.

yeah something is incorrect here, if the a/c started diving, waiting 2800 feet is a LONG time for the crew to respond, also, for a 2800 dive to stop and come out, there would be a lot of vertical space required, i really dont think this story is accurate at all....

I saw this last night on the London local news, the local MP for Barnes in west London was "very concerned" over this incident. The news report ended by saying El Al "refused to comment".

Here is a link to the official report by the AIAB (Air Accidents Investigation Branch). If you follow the link down to the bottom of the page you will see a full copy of the report in pdf. format.

http://www.aaib.dft.gov.uk/publicati...er_2006/boeing_747_412__4x_els.cfm

Sorry to duplicate the link, I somehow missed it above in 777236ER's post.
p.s. The date of the incident was 10/01/06.

That puzzles me a bit but what do I know?

Aircraft have glideslopes now? (Sorry, JFK69, I know you're just the messenger).

From the AAIB report linked above:

"Investigations revealed no fault, either on the aircraft or in the ground equipment, to explain the incident."

In British English it was 10/1/06 but in American English it was 1/10/06. So even if you are 'flying' a British/English/Scottish/Welsh or American flag it would hely everyone if dates were put in a 1 Jan 06 format to eliminate any confusion. Thanks.

Why doesn't everyone follow Date/Month/Year like normal people??

Sounds kind of like the AF343 at YYZ but in reverse. (too low instead of too high)

Interesting story. It gives you an idea of how delicate our world has become. If an Isreali 747 had been perceived to have been brought down by terrorists over central London the consequences would have been tremendous.

Don't get me started on the media hyping things like this up. An aircraft descends, so it becomes a 'dive'. That emergency landing at BHX a while back by a TNT 737 became a 'crash' and a 'crash landing', both of which imply a much more serious incident than the one that actually happened.

El Al spokesperson said none of the pax even noticed.... So I think the comment.... "it was a descent not a dive applies" here. It went from 4000 feet to 1200 feet while it was on approach.

Don't aircraft normally descend on approach to land at an airport?? I am so confused. AP says the aircraft lost contact with the airport ILS glideslope.

How is the media so out of touch with reality? If the pax really felt a 2800 foot dive over downtown London. Doesnt anyone think that one or two of the 450 might have mentioned it back in January???

El Al's current active fleet is 30 aircraft. They do heavy checks/maintenance for Air Canada, Continental and BA not to mention the other airlines in Israel. They must be really bad at it, if all those folks continue to use them.

What ever happened to clicking a malfunctioning autopilot off and flying by hand?
To let a 2800 foot altitude deviation intentionally go unchecked is kind of a big deal. If the crew wants to troubleshoot a malfunctioning system, a landing approach close to the ground with revenue pax in the back is a pretty poor place to do it.
Airplanes are cool. Aviation sucks.

You need to tell El Al that.

I've personally seen non-El Al aircraft in the hanger at Ben Gurion.
