Analysis

The low time pilot departed with two relatives aboard for a local flight. The aircraft was observed flying low over omak lake and then commencing a climbing left turn toward higher terrain. During the climbout, the pilot perceived a loss of engine performance and applied carburetor heat. Outside air temperature was near 100 degrees resulting in a density altitude of nearly 6,000 feet MSL and the aircraft was near its gross weight. The aircraft was flown wings level into terrain whose rate of upslope exceeded the rate of climb capabilities of the aircraft for the given conditions of the flight.
