Preliminary information on an Iberia Airbus A350-900 diversion to Boston shows the crew received a warning that exhaust gas temperature on the left-hand engine was over limit.
The aircraft (EC-MYX), powered by Rolls-Royce Trent XWB-84 engines, had been cruising at 41,000ft en route from Madrid to New York JFK on 11 September.
It had been around 70nm south-east of Halifax when the crew received the ‘EGT over limit’ caution, says the Transportation Safety Board of Canada.
This subsequently escalated to an ‘engine fail’ message.
“The engine was secured and the flightcrew declared a ‘Mayday’,” says the board.
Flight IB6252 diverted to Boston where it landed uneventfully, with no injuries among the 265 passengers and 11 crew members.
“The operator’s maintenance [personnel] replaced the engine, and the aircraft was returned to service,” adds the board.
Circumstances of the warning and subsequent failure have yet to be determined.
Flight Fleets Analyzer lists the A350-900 as having been delivered to Iberia less than seven weeks before the incident.
