WHILE ENGAGED IN SEISMIL WORK, THE PLT WAS CONTACTED BY RADIO & WAS ASKED TO ASSIST IN FREEING 2 CREW TRUCKS THAT HAD GOTTEN STUCK IN SAND DUNES. HE DECIDED TO ASSIST SINCE THE STUCK TRUCKS WERE DELAYING THE ENTIRE OPERATION. HE PLANNED TO PARTIALLY RAISE & PULL ONE END OF A TRUCK BY USING A 100 FT LONG LINE. THE HELICOPTER WAS FACING THE AFT END OF THE TRUCK & LONG LINE WAS AT ABOUT A 25-30 DEG ANGLE WHEN CONTINUOUS COLLECTIVE POWER WAS APPLIED. BY THE PLT. THE HELICOPTER THEN YAWED LEFT.
