Air passengers planning to use East Midlands Airport were this afternoon still being advised to contact their airlines before travelling - as flights out remained suspended.
It follows an incident when a cargo plane suffered a landing gear failure in the early hours of today.
Freight company Air Contractors said there were only two crew members on board one of its planes, a Boeing 737-400, and neither was injured.
This afternoon airport officials said they did not know what time the airport would reopen.
Air Contractors, in a statement on their official web site, said: “The left-hand landing gear of the aircraft suffered a failure after the aircraft had successfully landed and whilst slowing for taxi off the runway.
“The runway remains closed whilst technical examinations take place, but the aircraft will be removed as soon as possible.”
Air Accidents Investigation Branch (AAIB) experts are at the airport
Some passengers have been taken by bus to Manchester Airport for alternative flights.
An East Midlands Airport spokesman said: “Runway operations are currently suspended until further notice. We are working hard to reopen the airfield quickly.”
The airport currently serves about four million passengers and handles 300,000 tonnes of freight each year.
