Analysis

It was reported that the plt had been giving rides to various family members & the acft was observed flying in the area of Conchas lake on several occasions. It was also reported that the acft had 'buzzed' boats on the lake several times during the day. The accident flt departed the arpt with four adults aboard; three brothers & one sister. The acft departed rwy 9 & traveled about 3/4 mi before impacting in the desert in a steep nose down attitude. Examination of the throwover control wheel & its pivoting arm, which had separated, indicated it was most probably positioned for use by the right seat passenger who was not a certificated plt. The plt's muscle tissue alcohol level was 0.113
