Air safety officials deny
claim that BA jet was close to catastrophe
UK authorities
deny US investigators' claim that one engine shut down and one was on fire
before Heathrow emergency landing
Workers examine the British Airways plane
after the emergency landing at Heathrow.
The UK air accident
investigation board (AAIB) has denied reports from US safety authorities that
the British Airways jet which made an emergency landing last week at Heathrow
did so with one engine shut down and the other on fire.
The AAIB, which
is expected to publish an interim report on Friday, took the rare step of
denying reports from the website of the US national transportation safety board
(NTSB), which is assisting the AAIB, on the incident.
British
investigators did not, however, contradict a US claim that heavy protective
coverings, or cowls, on both engines were torn from the plane on or after
takeoff.
The information from the US government, if correct, suggests the
plane came closer to potential catastrophe - making the incident much more
serious than so far revealed, safety experts say.
The London-Oslo flight
BA762 returned to land at Heathrow soon after takeoff on the morning of Friday
24 May. Passengers on board and witnesses below saw smoke billowing from the
plane, which landed safely, with the 75 passengers and crew evacuated via
emergency slides.
The NTSB is assisting the investigation because the
engines were manufactured for Airbus in the US. On its website, it noted that
the BA plane saw "the engine cowls from both International Aero Engines V2500
engines separate and fall on to the runway. The pilots reported that they shut
down one engine, there was a fuel leak, and that they were
returning."
The NTSB continued: "The pilots subsequently reported that
one engine was shut down and the other engine was on fire." The AAIB later
asserted that this information was incorrect.
It has emerged that Airbus
has noted 32 similar incidents on its A320 family of planes, including the A319,
in which the engine cowls - roughly equivalent to the bonnet of a car - have
flown open or detached in flight, causing potentially serious damage to the
plane. The manufacturer issued a safety briefing last year, urging crews to be
aware of the risk of cowls not being properly closed.
The AAIB's full
conclusion is likely to be months away, but it will issue a special bulletin on
Friday. BA said it would not comment on the incident but was conducting an
investigation, co-operating fully with the AAIB and awaiting its full
report.
David Learmount, operations and safety editor of Flight Global,
said: "This was more serious than we realised at the time - this was a serious
incident. If you have fires in the engine, and cowls falling from both engines,
that is very dangerous." He added that the crew did well to avert loss of life
on board and under the flight path.
Passenger Jean Ralphs, who was
sitting in seat 3F, says she saw an engine cowl detach. "I saw vapour streaming
off the right-hand engine and a colourless liquid streaming from the exposed
pipes. It was obvious that it was only a matter of time before the engine caught
fire.
