Investigators probe third accident at Halifax airport in 15 years

Investigators have arrived at Halifax Stanfield International Airport to begin work on piecing together why a Boeing 747 cargo plane skidded off a runway while landing Wednesday.

The crash left a trail of debris and sent four crew to hospital.

SkyLease Cargo Flight KK0E 4854 overshot Runway 14 just after 5 a.m. - the third serious incident at Stanfield in 15 years, following crashes in 2004 and 2015.

Airport spokeswoman Theresa Rath Spicer says the plane was arriving from Chicago in rainy conditions, and scheduled to be loaded with live lobster destined for China.

Larry Vance, an accident investigator now in private practice, says the investigation will take time, but it appears the plane was landing with a strong tailwind - something he says is a bit of a red flag.

Vance says while it's possible to land with a tailwind, there would be little room for ``deviations'' such as a high airspeed or delayed touchdown.

He says another potential factor in the accident could have been the rainy conditions, which can lead to hydroplaning.
