Analysis

The acft descended at a flat angle under power into trees after the engine lost power. The pilot took off at 1010 for a sightseeing flight. The temperature was 78 and the dew point was 65 degrees f. after about 30 minutes of flight the pilot turned to avoid clouds and began to lose altitude. He added throttle but could not get full power. The aircraft continued to descend with best climb airspeed and full throttle. Maintaining what power he could and a flat rate of descent the pilot flew into a slightly upward sloping group of trees in the makaha valley.
