Factual narrative

On April 26, 2010, about 1523 Alaska daylight time, a Piper PA-32-301 airplane, N8305H, sustained substantial damage when the landing gear collapsed during a hard landing at the King Cove Airport, King Cove, Alaska. The airplane was being operated by Peninsula Airways Inc., as Flight 421, a visual flight rules (VFR) scheduled commuter passenger flight under Title 14, CFR Part 135, when the accident occurred. The airline transport pilot and the four passengers were not injured. Visual meteorological conditions prevailed, and company flight following procedures were in effect.
