No one was injured when an aircraft from Manchester with 48 passengers and four crew on board came off the taxiway at Inverness airport.
The incident happened after the Flybe aircraft landed and while it was taxiing at low speed, the BBC reported.
The passengers and crew were able to leave the Q400 turboprop aircraft.
The airport fire service attended the scene, as is routine, but its services were not needed.
The incident involving flight BE202 disrupted air traffic to and from Inverness, including a flight from London City which was diverted to Aberdeen.
A Flybe spokeswoman said: “Flybe can confirm that when taxiing at low speed at the end of the runway, having landed safely at Inverness airport this morning, the wheels of the Q400 aircraft skidded on the surface of the airfield, causing it to slide on to the grass.
“The passengers and four crew were unharmed and exited the aircraft by the stairs for bus transfer to the terminal, where they collected their luggage as normal.
“The safety of its passengers and crew is the airline’s number one priority and Flybe regrets any inconvenience experienced as a result of this incident.”
An investigation into the circumstances of the incident is being carried out by the Air Accident Investigation Branch.
