Air Canada landing prompts FAA probe
SAN FRANCISCO — The Federal Aviation Administration in the United States is investigating why an Air Canada passenger plane ignored repeated orders by air traffic control at San Francisco International Airport to abort a weekend landing, officials said Tuesday. After landing safely, the plane reported a radio problem and Air Canada subsequently said the cockpit never received the orders.
The Sunday night incident happened three months after another Air Canada jet with 140 people on board nearly landed on a crowded taxiway at San Francisco’s main airport.
The close call in July prompted the FAA to issue new rules for nighttime landings and control tower staffing at the airport.
The latest incident involved Air Canada Flight 781 from Montreal, an Airbus A320 that was given initial clearance to land when it was about 10 kilometres from the airport, FAA spokesman Ian Gregor said. The cockpit acknowledged the instruction.
But air traffic control then issued multiple orders for the jet to “go around” because it believed another plane may have been in the runway, Gregor said in a statement.
Audio from the control tower posted by the East Bay Times indicates the Air Canada flight was told six times in less than a minute to “go around,” or interrupt its landing procedure. The instruction was met with silence, according to the audio clip.
The air traffic control supervisor then used a flashing “red light gun” shined out from the control tower windows toward the plane to alert the crew to go around, Gregor said. Doing so is a standard procedure when an air crew does not respond to radio instructions.
“After landing, the Air Canada crew told the tower they had a radio problem,” Gregor said. He said the FAA was investigating.
He said that a radar replay showed the runway was in fact cleared of the earlier arrival when the Air Canada flight landed.
Air Canada spokesman Peter Fitzpatrick also said the company is investigating the incident.
“After receiving proper clearance to land it proceeded to do so and landed normally. Upon landing the crew was informed the tower had attempted unsuccessfully to contact the aircraft, however the message was not received by the crew,” Fitzpatrick said.
