EXAMINATION OF THE AIRCRAFT DISCLOSED THE LND GEAR DOORS WERE DAMAGED BY THE SIDE LOADS AND THAT BOTH MAIN LND GEARS WERE EXTENDED BUT NOT LOCKED. THE NOSE GEAR STRUT WAS FOUND IN THE DOWN & LOCKED POSITION. THE UNDERSIDE OF THE FUSELAGE WAS NOT DAMAGED WHICH IS CONSISTENT WITH THE MAIN LND GEARS TO BE PARTIALLY EXTENDED AND HYD PRESS TENDING TO HOLD WHEELS IN DOWN POSITION. THE NOSE GEAR EXTENDS AND LOCKS BEFORE THE MAIN LANDING GEAR. THE PLT DELAYED EXTENTION OF THE LND GEAR UNTIL NEAR THE FLARE POSITION.
