Despite the original reports that it was a bird strike on both engines, looks like this one falls into the human error category.Heathrow emergency landing: Engine doors 'left unlatched'
The doors on both engines of the flight that made an emergency landing at Heathrow last week had been left unlatched, investigators have found.
Air accident experts said the coverings - the fan cowl doors - broke off and punctured the right engine's fuel pipe, damaging the aircraft's systems.
A fire then broke out in the right engine of the Airbus A319 British Airways flight to Oslo.
The jet landed safely and its 75 passengers and crew were evacuated.
The aeroplane returned to Heathrow soon after taking off last Friday when black smoke was seen coming from an engine.
The findings were made in an interim report by the Air Accidents Investigation Branch (AAIB), which is examining the cause of the emergency.
'Appropriate initial action'
The fire in the right engine broke out as the flight prepared to land, but the left engine was unaffected, the AAIB report said.
"Subsequent investigation revealed that the fan cowl doors on both engines were left unlatched during maintenance and this was not identified prior to aircraft departure," the report added.http://www.bbc.co.uk/news/uk-england-london-22732582
