Incident Summary
A pilot reported that shortly after takeoff from a 6,700-foot-long runway with a density altitude of 10,400 feet, the aircraft experienced turbulence. The airspeed decreased to approximately 70 knots, and the aircraft was unable to maintain altitude. The pilot attempted a forced landing, during which the aircraft contacted a fence.
Pilot Report
The pilot stated, "We completed procedures according to owner's manual for weight and balance, runway length, performance and runup." The takeoff was accomplished with 10 degrees of flaps lowered, and after takeoff the aircraft was accelerated to 90 knots.
Operational Conditions
The airport is located in a mountain valley with rising terrain in all directions. The maximum density altitude on the takeoff versus density altitude chart in the flight handbook is 7,000 feet. The recommended short-field takeoff procedure calls for 25 degrees of flaps and acceleration to 80 miles per hour until obstacles are cleared.
