Analysis

Bfr deptg tucson, AZ on a return flt to long beach, CA, 2 student helicopter plts (the owners) were advised VFR flt was not rcmdd due to low ceiling/vis at the destn. Neither plt was endorsed for x-country flt. En route, they lndd/refueled at gila bend & parker, AZ. At 2124 PST, they told TRACON they were VFR at 4500' & rcvd vectors to long beach. However, drg arrival, the arpt was not visible due to a 500' overcast. The crew rprtd 40 min of fuel remaining & reqd vectors to the nearest arpt with VFR conds. Ontario intl & norton afb were the only arpts in the area with no ceiling; both were rprtg aprx 1 mi vis with fog & haze. The crew diverted to Ontario & were clrd for a special VFR dscnt to rwy 26L. About 3 min later, while dscndg thru 2000', their clnc was amended due to possible conflicting traffic. Shortly thereafter, radio & radar contact with the acft were lost. At 0151, the acft was fnd aprx 1 mi south of the arpt where it impacted in a nose low, left bank attitude. Tests showed 1 student (presumed 2ND-IN-command) had a blood/alcohol lvl of 0.160%.
