Emergency crews were called out to Blackpool Airport after a pilot reported smoke coming from the cockpit of an aircraft.
The pilot of the private plane notified services shortly after 8am on Wednesday morning.
But by the time fire crews from Forest Gate and South Shore fire stations, along with police and paramedics, arrived at the Squires Gate Lane airport the incident had been dealt with.
Sue Kendrick, corporate affairs manager for the airport, said: “Emergency crews were called out as a precautionary measure but the pilot then realised it wasn’t a full emergency.”
A spokesman for Lancashire Fire and Rescue said: “We were notified at 8.04am and mobilised crews from Forest Gate and South Shore were mobilised and Lytham were put on standby.
“It looks like it was a precaution to alert us but then it was dealt with.”
