New York places specific duties on ski area operators, including the duty to inspect the condition on each run twice a day, pad lift towers and man-made objects, and post signs and notices. N.Y. Gen. Oblig. Law § 18-103. The statutory duties are not exclusive and common law principles must be applied unless a particular hazardous condition is specifically addressed by the statute Sharrow v. New York State Olympic Reg’l Dev. Auth., 746 N.Y.S.2d 531, 542 (N.Y. Ct. Cl. 2002), aff’d, 762 N.Y.S.2d 703 (N.Y. App. Div. 2003). Skiers have their own set of duties defined in statute. N.Y. Gen. Oblig. Law § 18-105.
