GF A320 Crash At Bahrain On 23th Aug 2000!

Tue Sep 17, 2002 5:00 pm

I know the text on airdisaster.com
But I still have no idea why this Aircraft crashed. I know why they made a go around but why crashed they with about 280kts in the Gulf.
It would be very nice if somebody could give me some detailes informations about what happened in that night.
thanks in advance

regards bjoern

Crew bodged the initial approach to Bahrain and asked to perform an orbit to stabilise the aircraft. The orbit itself was a mess and failed to achieve the desired stabilisation, so the A320 then opted to go-around.

During the go-around the aircraft headed out towards the sea. It is presumed that the combination of full-power acceleration and the lack of visual cues from outside the aircraft caused a degree of spatial disorientation (the 'somatogravic' illusion whereby the brain mistakenly interprets acceleration as increasing pitch-up because of the similar effects which both motions have on the ear canals).

This false 'pitch-up' sensation probably prompted the captain to push the nose of the aircraft downwards, leading him to send the aircraft unintentionally into a dive at full power. The final error was the crew's failure to respond adequately and quickly to the GPWS warning as the jet headed for the sea.

Failure to follow standard operating procedures, basically. And pretty poor airmanship all round.

Is there any CVR script, where we can read the last conversations between F/O and Cpt.
I wonder if both made the fatal mistake in desregarding their instruments.
Anyway thank you Bacfire!

Sorry, can't say anything about the reason but I remember that I was in BKK at the airport and saw this on CNN...

Bahrain's investigation team has the CVR transcript for GF072 available here:

I read the CVR transcript, Why does ATC ask for the number of "souls" aboard? is this standard procedure?

Didn't these guys nearly stall the airplane before they dove it into the ocean? I thought I read that somewhere. It seems like that it would be really difficult to do that considering the A320/330/340 have safeguards to prevent stalls, excessive banks, and other features. They must have put the aircraft into "direct law" (?) for it to push it that far.

This is standard procedure. ATC wants to know this information in order to scramble the requsite amount of firefighting equipment.

The aircraft did not stall. In fact it reached a speed in excess of 185kts while climbing during the go-around and an alarm prompted the first officer to issue an overspeed warning.

I read the same explanation in Aviation Week's review of the final crash report Backfire. Although, the report did state that there were a number of contributing factors (in addition to the above).
I dumped at the gybe mark in strong winds when I looked up at a Porter Q400 on finals. Can't stop spotting.

There were not two go-arounds. The pilot carried out a 360-degree orbit during initial approach in an attempt to stabilise the flight path. But the aircraft was, by then, too close to the runway to make a safe approach and the pilot took the decision to go-around and try again.

It was during this first go-around that the accident occurred.
