Analysis

During a visual apch, the plt said he encountered 2000 fpm downdrafts. The plt stated he added power and executed a normal apch at 120 KTS, compensating for downdrafts/crosswinds. After touchdown, the plt said he did not get a beta light on the right eng. He stated he brought the pwr levers 'behind the gate into reverse.' The acft drifted left. The plt said he corrected with brakes and nosewheel steering. He applied takeoff power and the acft veered right, and ran off the right side of the rwy. The acft collided with a dirt bank and then trees. Three tire skid marks were observed onthe right side of the rwy. A plt-witness said winds were gusting 22-25 KTS, variable from 130-220 degrees. He said the acft landed fast and long. Exam of the engines and props revealed no evidence of malfunction. The engine manufacturer recommends prop reverse not be used on icy rwy or when beta light on one engine does not illuminate. The acft manufacturer advises that nosewheel steering should not be used at speeds below 40 knots.
