The federation said its ski jumping committee requested the suspension of national team coach Magnus Brevik and equipment manager Adrian Livelten after two Norwegian athletes were disqualified on Saturday.
Acting General Secretary Ola Keul said the suspensions were immediate until further notice.
“The information that has emerged so far about the events… is so serious that it provides grounds for suspending their employment,” the federation said in a statement on Monday.
Stine Korsen, the chair of the ski jumping committee, said that Norway would welcome an investigation by the International Ski and Snowboard Federation (FIS) into the cheating.
“We take this matter very seriously and recognise that equipment has been deliberately manipulated in violation of FIS regulations to gain an advantage in the competition,” Korsen added.
The federation said that Bine Norcic will act as coach while Brevik is suspended. “I have consented to the suspension… I’m sorry for what we did,” local media quoted Brevik as saying after he spoke to reporters on Monday.
“We have manipulated or modified the jumpsuits in a way that violates the regulations – ergo, cheated.”
Competitors Marius Lindvik and Johann Andre Forfang were disqualified from the men’s large hill competition at the Nordic World Ski Championships on Saturday after they finished second and fourth respectively.
Livelten, in a statement to local media, apologised to the athletes. “I would like to apologise to Marius and Johann for the situation they have found themselves in through no fault of their own,” he said.
“What we did with the suits should never have happened and is an action I will regret for the rest of my life. We have always done what we can to optimise the suits within the regulations, but cheating is completely unacceptable.”
