An inquiry is launched as Civil Aviation Department pledges more transparency A Cathay Pacific airliner made a priority landing in Osaka last night after one of its four engines was shut down during a flight from Hong Kong. The Airbus A330, bound for Osaka via Taipei on flight CX 564, was carrying 148 passengers and 13 crew. The captain requested a priority landing after seeing abnormal readings for the number two engine, which was shut down as a precaution, the Civil Aviation Department said. A Cathay spokesman said the crew requested a priority landing in line with the company's safety guidelines. None of the passengers or crew were hurt. 'The incident is under investigation. The Hong Kong Civil Aviation Department has been informed,' the spokesman said. The incident was the 13th in which the engines of Cathay planes have been shut down during flight this year. It occurred as the Civil Aviation Department pledged more openness in the disclosure of mechanical mishaps involving local airlines. The Civil Aviation Department did not inform the public when engine casings fell off two Cathay flights, in June and earlier this month, because it was not required to do so under international aviation guidelines, said deputy director-general of civil aviation Leung Yu-keung. But with a rise in media coverage and public concern over such incidents, Mr Leung said the regulator would disclose such incidents in future. 'If the public and the media are saying there is a grey area that should be published, we will. We promise. We are committed.' Mr Leung was speaking for the first time since reports appeared detailing five mishaps involving engine problems on Cathay planes. On December 1, a Boeing 777-300 flying from Bangkok to Mumbai was forced to turn around after an inner engine casing tore loose and hit a car in the Thai capital. A similar incident occurred on the same aircraft when it flew from Taiwan to Hong Kong on June 30, when a casing fell into the sea. Cathay reported both incidents to the Civil Aviation Department, but they were not made public because the agency was required to do so only in the event of death or injury, Mr Leung said. He said such minor incidents fell under the category of 'mandatory occurrence reports', which include small parts falling off aircraft, cracks appearing on windscreens and fire warnings being set off.
