The 4 crew members suffered minor accidents when the empty SkyLease Cargo aircraft slid 210 metres off the top of Runway 14 at Halifax Stanfield Worldwide Airport, which suggests the massive jet was headed in a southeasterly course.
“I consider it was the pilot’s request for that runway, however that is preliminary,” lead investigator Austin Adams instructed a media briefing at a lodge close to the airport.
He stated climate knowledge recorded seven minutes earlier than the plane landed confirmed the wind was gusting at 33 kilometres per hour from the west at 250 levels.
He stated the “sturdy westerly winds” created a crosswind for the plane, which included the potential for a “quarterly tailwind.”
Aviation analyst and former security board investigator Larry Vance has stated it seems the aircraft landed with a tailwind — one thing he referred to as an “speedy purple flag.”
Vance stated airplanes usually take off and land into the wind, which gives pilots extra elevate and, in consequence, extra management.
Nevertheless, all plane are designed to land with a crosswind or tailwind, although every plane has its limits, stated TSB investigator Isabelle Langevin. She stated the board shall be trying into the bounds for the Boeing 747-400.
When requested why a pilot would selected to land on a moist runway whereas coping with a tailwind, Adams stated all of it comes right down to what was determined within the cockpit.

“The results will be significantly critical when there is no such thing as a enough runway finish security space or appropriate arresting materials,” the board stated in a press release.
Within the days forward, Adams stated his group will interview the crew and obtain and analyze the info from the plane’s cockpit voice recorder and flight knowledge recorder. Additionally they plan to speak to witnesses, air visitors controllers and airport personnel.
