Factual narrative
On January 11, 1995, at 1930 central standard time, a Cessna S550, N287MC, registered to Maytag Corporation of Newton, Iowa, and operated by a crew of two ATP pilots, touched down with the left main landing gear off the left side of runway 32 (5,599' X 100' dry/asphalt) at Newton, Iowa, following an ILS approach. Instrument meteorological conditions prevailed at the time of the accident. The nose landing gear collapsed and the airplane sustained substantial damage. The crew of two and four passengers reported no injuries. The corporate 14 CFR Part 91 flight was operating on an IFR flight plan. The flight departed North Canton, Ohio, at 1800. Both pilots reported that after the ILS approach the airplane was initially lined up on the centerline of the runway; however, at 20 feet above ground level the airplane drifted off the right side of the landing runway. The Captain (flying pilot) attempted to return the airplane to the center of the runway; however, the airplane's left main gear touched down in the snow off the left side of the runway and the airplane exited the runway. -
