UPDATE 4PM: Pilot John Bain breathed a big sigh of relief after an emergency landing ended well at Toowoomba Airport.
Mr Bain, of Toowoomba, and his co-pilot had taken off from Roma and were preparing to land in Taroom when they noticed an indicator fault on the nose wheel.
They decided not to land where their passengers were waiting and instead flew to Toowoomba where there were more emergency services as well as engineers.
"I suppose it's not the best environment to be in, but we followed the procedure (and) did the emergency extensions," Mr Bain said.
He had about one-and-a-half hours of fuel left when he reached Toowoomba.
Emergency crews were waiting for the Beechcraft Super King Air as it made two low passes over Toowoomba Airport before touching down shortly after midday.
"The issue is I didn't know whether the gear was locked or not," Mr Bain said.
"The procedure I've been taught is we don't want weight on that nose wheel so I held it off as long as I could.
"I didn't reverse the engines to try and be as gentle as I could on it, I guess."
However, the nose wheel had locked into place and the plane landed safely.
"The plane is now here at the engineering shop about to go up on jacks and find out what the problem is."
