Analysis

The plt & his roommate went flying in a rented acft. The plt maneuvered the acft through a valley, reversed course, descended over an assembly of persons & while buzzing them collided with trees. The plt was able to fly the substantially damaged acft back to the departure arpt without further mishap. The plt said that during his flight a gusty wind condition had existed, & he knowingly flew in the valley below the level of the mountain tops. The plt also said that the turn he made to reverse course was 'too tight' & that he did not immediately take corrective action to regain altitude until after colliding with the trees. The passenger stated that in the vicinity of the accident site he 'likely knew some of the persons on the ground.'
