Runway lights baffled pilots on night of San Francisco near-miss

Construction lights were so bright they were confusing to pilots who tried to land at night in July 2017 when a fatigued Air Canada crew almost struck four aircraft on the ground in San Francisco, according to preliminary reports.
The National Transportation Safety Board (NTSB) released more than 500 pages of investigative reports, including a video recording of the July 7 event, but didn’t reach conclusions on what caused the airliner to come within feet of triggering a catastrophe.
Both pilots reported that they felt fatigued in the latter stages of their flight from Toronto. They were landing at about midnight local time, which was the equivalent of 3 am where they had slept the night before, according to NTSB. The captain told investigators he may have gotten less than six hours of sleep and his rest had been disrupted by a late flight the previous night.
As the Air Canada plane approached the runway, the copilot thought something “didn’t look right,” he told investigators. However, he wasn’t certain what was wrong and was “unable to process what he was seeing,” the NTSB said.
The copilot told the captain, who was at the controls, to abort the landing and climb at about the same time the captain decided on his own to do the same thing, according to the NTSB. Seconds later, an air-traffic controller radioed to the plane a command to cancel the landing.
Pilots on a flight that arrived in San Francisco four minutes earlier told investigators that “construction lights were so bright we could not determine the location” of the only runway open for landing that night.
An adjacent parallel runway to the left of where they were cleared to land was under construction and closed that night.
Both pilots on the previous flight said they checked with their on-board instruments to ensure they were lined up for the proper runway.
The NTSB released a low-definition, black-and-white video recording that showed the Air Canada plane passing close to the planes on the ground. It flew above or near two planes before climbing, the video shows.
The Air Canada Airbus SE A320’s pilots were supposed to land on the right of two parallel landing strips at San Francisco International. Instead, they lined up to touch down to the right of that runway on a taxiway where four planes were idling as they waited for permission to takeoff.
The incident came within feet of causing a fiery collision between two or more aircraft, according to NTSB data. The Air Canada plane was as low as 18 metres from the ground as the pilots aborted the landing and tried to climb, according to earlier releases from the NTSB.
The tail on the Boeing Co. 787 that was first in line on the taxiway is almost 56 feet high, according to the company’s website. That United Airlines plane had turned to enter the runway and the Air Canada plane appears to have passed just behind it, according to a radar plot released by NTSB.
The risk of collisions on the ground has been raised as a safety issue by the NTSB for decades.
