Eastern Airways is investigating how one of its planes veered off a taxiway and hit a light at Stornoway airport.
Passengers onboard heard a bang and the Saab 2000 ended up on the grass.
Fire crews from the airport attended the incident on Sunday evening.
There were no injuries among the 29 passengers and three crew onboard.
The flight is operated under a Flybe and Eastern Airways joint venture arrangement.
The aircraft was said to be listing to the left after it slowly deviated onto the grass. The pilot checked the wheel and travellers were told to disembark.
Passenger, radio presenter Derek Murray, later tweeted: “Never expect your Flybe pilot to miss runway on taxi away from airport.”
He added: “No one injured thankfully. A mortification on clear still night but little information from shambolic Flybe.”
Mr Murray praised the “excellent” Stornoway airport staff but criticised Flybe for slow communication “directly to passengers who endured the ordeal. Unbelievably poor.”
A Flybe spokesperson confirmed that “during taxi-ing prior to take-off of the flight operated by Eastern Airways, the aircraft wheels made contact on turning with one of the taxiway lights and was deflected on to the grass.
“All 29 passengers were disembarked by the aircraft steps without further incident and were bussed back to the terminal.
“The aircraft is undergoing engineering inspection.
“Flybe provided overnight accommodation for those requiring it and all were re-accommodated on the next available flight on an alternate aircraft this (Monday) morning.
“Flybe and Eastern Airways sincerely apologise to its passengers for the inconvenience experienced. The safety of its passengers and crew is the airlines’ number one priority at all times.”
The plane was later towed off the grass by an airport tractor and parked outside a hangar.
A spokesperson for airfield operator HIAL said: “We are working closely with the airline to ensure the aircraft is safely returned to service as soon as possible. The plane is secure and airport operations continue normally.”
Eastern engineers are flying to the island to inspect the damage.
