There was an operator, still in business, which, in the early 90s, had a B206 on cross-hire from its private owner. The owner looked forward to a monthly cheque to offset his costs, but the amount kept getting less and less.
He contacted the owner of the school and asked what was happening. "Oh, not much demand for a B206 at the moment."
One Sunday, he was passing the airport and saw his machine fly overhead. "Great, some money this month!"
But no cheque. He asked again, "No, it hasn't flown."
Owner checks the maintenance release, no entries.
He says to himself, "Self, something isn't right here."
He gets his maintenance company (different from the school) to fit a hidden Hobbs meter in the broom closet.
Next month, again "no flight", so he looks at the secret Hobbs which shows that it has been flown. The school had been pulling the circuit breaker for the Hobbs and flying unrecorded time - the maintenance had to be way overdue. He blew the whistle to CASA, and the Chief Pilot went for the high jump - a shame, because he was a nice guy and it was the hungry Owner of the school who got away with it and kept on going. Without the private B206.
The school was known as The Breaker Brothers since then.
