Engine fumes

Here’s the text to the listening from yesterday.

Enjoy!!

An Airbus A340, flying from Berlin (Germany) to Singapore with 246 passengers was preparing for departure. It had suffered an engine problem previously and this engine had been replaced.

The aircraft then departed for the flight to Singapore. During the flight high levels of oil consumption were recorded in the new engine. The cabin slowly filled with fumes and some passengers felt unwell. The bleed air supply for this engine was switched off and the fumes disappeared.

The aircraft continued to its destination for a safe landing. Several passengers received medical assistance upon arrival in Singapore but none were considered sick enough to be taken to hospital.

The plane completed its return flight to Berlin as normal before maintenance was carried out on the affected engine.
