A Korean Airlines Boeing 777-300, registration HL7532 performing flight KE-621 from Seoul (South Korea) to Manila (Philippines) with 267 people on board, was climbing out of Seoul’s runway 33L when the crew stopped the climb at about 7500 feet reporting they could not retract the nose gear. The aircraft entered a hold at 5000 feet for about 60 minutes and landed safely back on Seoul’s runway 33R about 80 minutes after departure.
The aircraft remained on the ground for about 80 minutes, then departed again and reached Manila with a delay of 3 hours.
According to official information the nose gear lock pin had not been removed after the aircraft was towed. The occurrence is being investigated.
