Analysis

The plt reported that the eng lost about 200 RPM during the takeoff roll and he decided to abort. During the abort the plt swerved to avoid a fence at the end of the rwy and the acft slid sideways collapsing the lt MLG. Investigation revealed a broken carburetor heat cable. The cable was worn in the area of the break. When the cable breaks the heat valve goes to the hot position.
