The International Ski Federation (FIS) has charged Norwegian ski jumpers Marius Lindvik and Johann Forfang, along with three members of their technical team, with tampering with their suits during the World Championships in Trondheim in March 2025. The alterations, intended to improve aerodynamic resistance, led to disqualifications and prompted protests. The accused face potential loss of results, medals, and eligibility for the Milano Cortina 2026 Olympic Games. FIS has tightened controls on ski jumping suits following the incident.

Ahead of the Winter Olympics, several athletes were disqualified at a Courchevel, France event for violating suit regulations, continuing from a scandal in March where the Norwegian team illegally modified suits during the FIS Nordic World Ski Championships in Trondheim. The International Ski Federation is tightening inspections, causing teams to balance technical innovation with regulatory compliance. Disqualifications in Courchevel, including athletes from the United States, resulted from waist size and technical specification failures. FIS Race Director Sandro Pertile expects fewer disqualifications as teams adapt, but the FIS is maintaining strict checks throughout the Olympic season. The earlier Trondheim scandal led to the termination of contracts for Norway's head coach Magnus Brevig, assistant Thomas Lobben, and staff member Adrian Livelten, plus suspensions for involved athletes, after deliberate suit manipulation was admitted.

The French Ski Federation has provisionally suspended Joël Chenal, a former Olympic medalist and national coach, following multiple allegations of sexual harassment involving minors between 2005 and 2021. The suspension follows a report in Le Monde detailing accusations from 12 women. Chenal denies the allegations and is also subject to a formal complaint for sexual assault. The federation intends to participate in legal proceedings and has acknowledged shortcomings in past investigations in 2009 and 2015, which allowed Chenal to continue coaching until 2017. Michel Vion, secretary-general of the International Ski Federation, has taken responsibility for past failures. The French Ski Federation has since asserted that it has strengthened safeguarding protocols.

The International Ski Federation (FIS) closes the 2024/25 season, marking a year of growth, inclusion, and global development in skiing and snowboarding. FIS expanded its global reach to 141 countries, adding new members like Azerbaijan and Saudi Arabia, and associate members like Benin, Bhutan, and Indonesia. FIS initiatives, including regional camps and technical programs, supported athletes and coaches, especially in emerging nations, with over 6,600 days of skiing and snowboarding delivered. Looking ahead to the Milano Cortina 2026 Olympic and Paralympic Games, FIS aims to build an inclusive platform for athletes to reach the highest level.

The Norwegian Ski Federation terminated the contracts of head coach Magnus Brevig, assistant Thomas Lobben, and team staff member Adrian Livelten due to their alleged involvement in tampering with competition suits at the Nordic World Ski Championships in March 2025. The manipulation aimed to enhance aerodynamic performance, violating FIS regulations. Several athletes, including Marius Lindvik, Johann Andre Forfang, and Robert Johansson, were also suspended, with Johansson subsequently announcing his retirement. The federation concluded the equipment was deliberately manipulated. Secretary General Ola Keul emphasized the seriousness of the case, and Jan-Erik Aalbu apologized for deceiving the sport's fans.
