The owner of the charter company Trans Air, Les Wright, is believed to be one of the four people killed in a plane crash in Papua New Guinea yesterday.
The aircraft was operated by Trans Air.
Three Australians and a New Zealander died when the jet reportedly overshot a runway on Misima island off the Milne Bay mainland during wet and windy weather.
Trans Air, which runs a charter and medivac service in PNG, is linked to the now defunct Australian airline Transair, which went into liquidation after a 2005 crash in north Queensland in which 15 people died.
Another of the PNG fatalities was 61-year-old marine pilot Chris Hart, of Sydney, who was on his way to guide a ship from Misima through the Great Barrier Reef.
One person, a New Zealander, survived the crash.
