For nearly one minute, an Embraer 190’s transponder falsely indicated that the airplane had lifted off, leading ATC to clear a Boeing 777 for takeoff on the occupied runway.
Inaccurate transponder information and an unheard radio transmission factored in a 2020 runway incursion involving two airliners attempting takeoffs from Toronto Lester B. Pearson International Airport with a combined total of 446 passengers and crew, the Transportation Safety Board of Canada (TSB) says.
Human factors were cited in an overwhelming number of cases of vehicular and personal deviations at U.S. airports, a new study says.
The TSB blamed an ATR 42’s runway excursion in part on a contaminant inside a propeller high-pressure pump that led to a condition called pitch-lock.
The TSB’s new Watchlist highlights runway safety concerns that have plagued the Canadian aviation industry for more than a decade.
