On January 3, 2001, about 1740 Alaska standard time, a wheel-equipped Cessna 172 airplane, N19771, sustained substantial damage during landing at the Atmautluak Airport, Atmautluak, Alaska. The airplane was being operated as a visual flight rules (VFR) on-demand passenger flight under Title 14, CFR Part 135, when the accident occurred. The airplane was registered to, and operated by, Village Aviation, Inc., Bethel, Alaska. The certificated commercial pilot, and the two passengers aboard, were not injured. Visual meteorological conditions prevailed, and VFR company flight following procedures were in effect. The flight originated at the Bethel Airport, Bethel, about 1730. During a telephone conversation with the National Transportation Safety Board investigator-in-charge on January 4, the pilot stated that while on final approach to runway 33, he inadvertently allowed the airplane to descend below his intended glide path. He said that in an attempt to arrest the descent he applied full engine power, but the airplane continued to descend.

He said that as he attempted to abort the landing, the airplane become airborne, drifted to the left of the runway, and settled into an area of soft snow. During the second touchdown, the nose wheel collapsed at the firewall bulkhead. The airplane sustained substantial damage to the engine firewall.
