The aircraft at the centre of the emergency landing at Heathrow last week landed after pilots shut down one engine as the other became engulfed in flames.
The US National Transport Safety Board (NTSB) said that during its departure from Heathrow, the two engine coverings on the British Airways Airbus 319 came off and fell on the runway.
The incident happened as the plane took off for Oslo last Friday, May 24.
The pilots reported that they shut down one engine and there was a fuel leak which meant they had to return. Subsequently the pilots reported that one of the engines was on fire, the NTSB said on its website.
On landing, the plane was shut down and passengers left the plane using the emergency slides.
NTSB said the Air Accidents Investigation Branch was investigating the incident.
