What happened
The pilot initiated a takeoff from a rural dirt strip measuring approximately 2700 feet in length. The operational environment was characterized by high density altitude conditions, which significantly reduced aircraft performance capabilities. Additionally, the aircraft was loaded to near its maximum gross weight, further compounding the performance limitations.
During the initial phase of the takeoff roll, the aircraft became airborne near the midpoint of the available runway. However, it failed to maintain sufficient climb gradient and settled back onto the runway surface. The pilot attempted to continue the takeoff, achieving liftoff again near the end of the remaining pavement. Shortly after becoming airborne for the second time, the aircraft impacted a ridgeline located approximately one-quarter mile from the airport boundary, striking trees in the process.
The investigation
Examination of the accident site and operational parameters revealed that the combination of high density altitude and near-maximum gross weight critically degraded climb performance. The short length of the unpaved runway provided insufficient margin for error during the takeoff phase. No mechanical failures were reported as contributing factors; the primary issue was the inability to clear obstacles due to inadequate performance.
Findings
The accident was caused by the pilot's decision to operate in high density altitude conditions with a load factor near the maximum limit on a short, unpaved runway. The resulting poor climb performance prevented the aircraft from clearing the terrain immediately following the airport. Contributing factors included the high density altitude, the near-maximum gross weight of the aircraft, and the limited length of the takeoff surface.
