Operations at Belfast International Airport were disrupted Oct. 4 after a TNT Airways-branded Boeing 737-400 freighter was involved in a landing gear incident, blocking both of the airport's runways. According to Flightradar24, the 24-year old aircraft (registered OE-IAG, serial number 25168) is operated by ASL Airlines Belgium and was flying in TNT colors at the time of the incident. After operating a previous sector from Liege in Belgium to East Midlands, OE-IAG departed for Belfast at 0520 and landed at 0556. A Belfast International spokeswoman said the aircraft had issues with its undercarriage and came to a halt at the intersection of the two runways, which are laid out in a t-shape. Nobody was injured in the incident. The disabled aircraft halted all arrivals and departures from the airport. Flights resumed about 90 minutes later, using just one departing runway with a restricted length of 1,900m, with the stranded aircraft still in place at the runway junction. Five inbound and five outbound sectors-all domestic-were canceled. Flights were delayed throughout the day, but by 1730 local time operations were returning to normal, or with light delays. The spokeswoman told ATW the aircraft was expected to be removed at around 1800 local time. "The TNT aircraft is now being moved to stand 11 we should be back to full length runways within the hour after a wee bit of a cleanup," Belfast International managing director Graham Keddie said via Twitter. The UK Air Accidents Investigation Branch was on the scene and identified the aircraft as a Boeing 737-400 freighter, which had "encountered difficulties with its landing gear." "The flight data recorders have been recovered and are being brought back to our laboratory in Farnborough for analysis, while our investigation continues in Belfast," the AAIB said in a statement.
