HISTORY OF FLIGHT On December 25, 2004, at 1021 central standard time, a Beech S35, N5631K, collided with trees and the terrain in Herman, Wisconsin, following a loss of engine power during flight. The airline transport pilot and a passenger were fatally injured. The airplane was substantially damaged by impact with the terrain and a post impact fire. The 14 CFR Part 91 personal flight was operating in visual meteorological conditions on an instrument flight rules (IFR) flight plan. The airplane departed the Manitowoc County Airport (MTW), Manitowoc, Wisconsin, at 1010, en route to the Lewis University Airport (LOT), Romeoville, Illinois.

Records compiled by the Federal Aviation Administration (FAA) indicate the following: At 0545, the pilot requested weather information through a direct user access terminal (DUATS). At 0620, the pilot filed an IFR flight plan and requested weather information through DUATS. At 0703, the pilot called the Green Bay Flight Service Station for an IFR weather briefing for a flight from MTW to LOT.

Probable cause
The installation of the improper cylinder base packing seals by maintenance personnel resulting in the loss of lubriation and subsequent failure of the number four connecting rod/bearing. A factor associated with the accident was the trees that the airplane contacted during the forced landing.
