STORY: Investigators say they know the cause of an engine failure on a Cathay Pacific flight.They blamed a damaged fuel hose which also showed signs of a fire.The probe was conducted by Hong Kong's Air Accident Investigation Authority,

A cleaning process leading to fuel hose degradation during refurbishment may have caused a recent Airbus A350 engine fire that triggered dozens of Cathay Pacific flight cancellations this month, the EU aviation regulator said Thursday.

An engine fire on a Cathay Pacific Airbus A350 earlier this month was the result of a fuel leak and could have caused extensive damage to the plane, according to investigators. Hong Kong’s flagship airline grounded planes after being forced to turn a flight around a couple of weeks ago because of an "engine component failure".
