Analysis

During a landing on rwy 14R, the acft veered off the left side of the rwy, hit a rwy sign & was damaged. At the same time the DHC-6 was approaching to land, a Boeing 727 was also in the traffic pattern to land on rwy 14L. According to tower personnel, the Boeing landed about 1 mi after the Dehavilland landed. However, there was evidence that the Boeing closed & possibly passed the Dehavilland during the landing sequence. The wind was from 360 deg at 10 KTS which would have drifted wake turbulence toward rwy 14R. The Dehavilland captain reported that the power levers were stiff & that the left prop sounded like it surged during the landing just after the coplt (who was flying the acft) selected ground beta. When the captain realized that the coplt could no longer control the acft, he took the controls, but was unable to avoid colliding with the rwy sign. There was minor damage to the landing gear strut fairings.
