A JetBlue airliner with 146 people aboard made an emergency landing at Los Angeles International Airport on Wednesday, dragging its crippled nose gear down the runway in a hail of sparks and smoke before coming safely to rest. There were no immediate reports of injuries during the drama, which began when pilots realized the plane’s front wheels did not retract properly on takeoff and ended after the Airbus A320 jet circled the southern California coast for three hours to burn off fuel. The entire incident played out on live television, with a number of US networks carrying pictures of the airborne Flight 292 with its nose gear turned sideways.

Images of the landing showed the pilot easing the plane onto the airport’s longest runway as smoke and sparks shot from the burning front wheels before the plane came to a rest. Flames were no longer visible by the time the plane had stopped. Fire and emergency crews surrounded the plane, which had been en route from nearby Burbank to New York, and a truck equipped with a stairway pulled up to the aircraft. Passengers, some smiling, streamed calmly off, guided by firefighters in silver flame-retardant suits. Buses then took them to a terminal.

Alexandra Jacobs, 6-1/2 months pregnant, recalled members of the flight crew chanting “Brace, brace, brace” as the plane touched down. “That for me was scary, because it felt like a prayer,” she said. JetBlue said it was working with the Federal Aviation Administration, the National Transportation Safety Board and Airbus (NTSB) to investigate the cause of the mishap. The plane, dubbed “Blue Canyon,” was carrying 140 passengers and a six-member flight crew, consisting of two pilots and four flight attendants.

Flight 292 left Bob Hope Airport in Burbank at 3:17 p.m. and was bound for New York’s John F. Kennedy International Airport. JetBlue said the pilot was advised to circle the region to burn off fuel and lower the weight of the plane before attempting to land. A similar incident involving another Airbus A320 occurred in February 1999. The NTSB found then that there had been three previous such incidents.

Airbus spokeswoman Mary Anne Greczyn said jets by other manufacturers had experienced similar problems. “This has happened with just about every make and model of aircraft that is out there,” she said. But John Nance, an aviation analyst and former Air Force pilot, said the incident raises safety concerns. “The NTSB will get involved, the FAA will get involved, and they will ask, ‘Is this a chronic problem?” he said.
