A Civil Aviation Authority investigation found Dickie also failed to correctly maintain his pilot logbook, aircraft technical log and daily flight records.
Authority enforcement manager Rob Scriven said Dickie's explanation - that poor weather and bad visibility caused him to make the dangerous turn - was not acceptable.
"If weather is causing you to make non-standard turns at an aerodrome, then that's a very good reason not to have taken off in the first place."
Mr Scriven said student pilots at Ardmore had stayed on the ground that day due to the weather conditions.
Dickie was fined $2300 and ordered to pay court costs of $664.45.
