Today the Bureau of Enquiry and Analysis for Civil Aviation Safety (BEA) has issued a call for witnesses regarding a serious incident relating to a Swiss A220.
On 25th July 2019, a Swiss Airbus A220-300, with registration HB-JCM and performing flight LX-348 from Geneva (Switzerland) to London Heathrow (UK), suffered an engine shut down mid flight.
During the cruising phase over East of France the left engine, a Pratt & Whitney PW1524, emitted a bang and produced streaks of flames. Immediately after, the crew shut down the engine and diverted the flight to Paris – Charles de Gaulle airport.
The aircraft landed safely 30 minutes after the incident, with no injuries reported. A post flight examination revealed that the low-pressure compressor rotor stage 1 was missing from the engine.
The BEA issued a call for witnesses regarding engine parts that may have fallen in an unoccupied wooded area near the towns of Perrigny-sur-Armancon and Cry. The four points of the search zones are shown in the next map:
The missing parts are from the low-pressure compressor and are made of titanium; each part should not exceed a length of 30cm.
In accordance with international rules, the BEA has delegated this investigation to its US counterpart, the NTSB, as representative of the engine state of design.
