A Beechcraft A36 Bonanza, N321TB, was substantially damaged when it was involved in an accident at the Alton Bay Seaplane Base (B18), Alton Bay, New Hampshire. The pilot and passenger were not injured.
A witness-recorded video shows the aircraft on final approach to the ice runway when it landed hard (short) and struck a snowy-berm. The right landing gear collapsed and the airplane slid off the ice and struck another pile of snow before coming to rest.
The Alton Bay Seaplane Base is a state-owned, public-use seaplane base located in a cove of Lake Winnipesaukee. During the winter months, the base may seasonally open an ice runway instead of the normal seaplane landing area. It is the only FAA approved ice runway in the USA.
