South Korea jet crash puts fast-growing Jeju Air's safety under scrutiny

Before it suffered the deadliest crash in South Korea's history, budget airline Jeju Air was moving fast: racking up record passenger numbers and flying its aircraft more than domestic rivals and many of its global peers, data show. The high "utilisation rate" of Jeju Air's planes - the number of hours they fly in a day - is not problematic in itself, experts say, but means scheduling enough time for required maintenance is crucial. Authorities have suggested a bird strike contributed to the accident, but as part of their probe into the incident aboard Boeing 737-800, police have raided the airlines' Seoul office to seize documents related to the operation and maintenance of the plane. "You're literally looking at everything," said aviation safety and crash investigation expert Anthony Brickhouse. "You're going to start off with their accident history and safety history. What kind of events have they had in the past, what happened, what was done to correct the issues?" Jeju Air told Reuters that it did not neglect maintenance procedures and that it would step up its safety efforts. The Dec. 29 crash, which killed 179 people, was the airline's first fatal accident since its 2005 founding and the first for any Korean airline in more than a decade. The company's CEO, Kim E-bae - who has been barred from travelling overseas during the investigation - told a news conference last week that Jeju's maintenance is in line with regulatory standards and that there were no maintenance issues with the doomed jet during pre-flight inspection.<br/>
