A Northern Territory airline has been banned from operating passenger flights because its pilots failed a qualifications test.
Fly Tiwi, which is owned by Hardy Aviation, has grounded its regular passenger planes that fly to the Tiwi Islands and other communities.
The Civil Aviation Safety Authority suspended Fly Tiwi's licence because two senior pilots did not pass a safety test.
The company's managing director John Hardy says the pilots will re-sit the test this week.
"I'm very hopeful that we will overcome this glitch soon by the end of the week or even sooner if we're lucky," Mr Hardy said.
"But if people want to travel and they want to go by air, they can charter a plane.
"We can offer that sort of service or they can try somebody else."
