SUBJECT AIRCRAFT LANDED AT KHBI WITH AIRCRAFT LOWER FUSELAGE CONTACTING THE RUNWAY 3 VEERING LEFT AND EXITING THE RUNWAY COMING TO A STOP APPROXIMATELY 200 FEET FROM THE RUNWAY. THE LANDING GEAR WERE IN THE WHEEL WELLS AND LANDING GEAR DOORS DAMAGED. VARIOUS ANTENNAS WERE BROKEN ON CONTACT. THE LEFT PROPELLER INDICATED AN ABOVE GROUND IDLE SETTING AS IT CONTACTED THE GROUND WITH POWER. ALL FOUR PROPELLER BLADES WERE BENT AFT AROUND 90 DEGREES WITH THE TIPS CURLED. THE BLADES ALSO STRUCK THE INLET SCOOP FOR THE ENGINE. THE LEFT PROPELLER ALSO CONTACTED THE GROUND AND ALL FOUR BLADES WERE BENT AFT AROUND 30 DEGREES. THE NOSE WHEEL WAS ANGLED APPROXIMATELY 45 TO 50 DEGREES TO THE LEFT ON ITS STEERING AXIS, CAUSING THE AIRCRAFT TO STEER LEFT AFTER LANDING. INITIAL RUNWAY MARKS WERE INDICATION OF THE LEFT PROPELLER CONTACTING THE RUNWAY AND THE RIGHT ALSO ABOUT 50 YARDS LATER. THESE MARKS INITIATED APPROXIMATELY 1500 TO 2000 FEET FROM THE APPROACH END OF THE RUNWAY. AFTER APPROXIMATELY 100 FEET OF PROPELLER CONTACT MARKS MAIN LANDING GEAR DOOR CONTACT MARKS BEGAN A AROUND 6 INCHES APART FOR EACH SET OF GEAR DOORS. AS THE AIRCRAFT PROCEEDED DOWN THE RUNWAY, THE MAIN GEAR DOOR CONTACT MARKS WIDENED TO AROUND 15 INCHES.. THE MARKINGS BEGAN TO VEER TO THE LEFT AND TIRE MARKINGS BEGAN TO APPEAR. NO TREAD MARKINGS WERE IN THE SKID MARKS. THIS YAW ANGLE WAS CAUSED BY THE NOSE STEERING SYSTEM LINKAGE BROKEN AS THE NOSE LANDING GEAR WAS ATTEMPTING TO BE EXTENDED. THE MAIN GEAR TIRE MARKS WERE ALSO INDUCED BY THE GEAR ATTEMPTING TO EXTENDING BUT UNABLE TO BECAUSE OF THE WEIGHT OF THE AIRCRAFT AND AIRCRAFT PROXIMITY TO THE GROUND. MINIMAL DAMAGE TO THE MAIN CENTER SECTION OF THE BOTTOM FUSELAGE. SUBSTANTIAL DAMAGE WAS INDUCED ON THE AFT SIDE OF THE FUSELAGE BOTTOM. (BEHIND THE MAIN ENTRANCE DOOR) FLAPS WERE EXTENDED IN THE APPROACH POSITION AND THE LEFT FLAP RECEIVED CONTACT DAMAGE AND SLIGHT BUCKLING. THE RIGHT FLAP APPEARED TO CONTAIN MINIMAL DAMAGE. UPON RETRIEVAL OF THE AIRCRAFT FROM THE SIDE OF THE RUNWAY TO THE RAMP AREA, THE LANDING GEAR WERE CONSTRAINED IN THE GEAR WELL AREAS BY THE DAMAGED GEAR DOORS. ATTEMPT TO EXTEND THE GEAR BY EMERGENCY EXTENSION SYSTEM PRODUCED THE RIGHT MAIN AND NOSE GEAR EXTENSION AND LOCK. THE NOSE GEAR CONTINUED TO REMAIN IN THE 45 TO 50 DEGREES STEERING POSITION. (IT WAS BROUGHT BACK TO STRAIGHT BY A MANUAL METHOD). THE LEFT MAIN GEAR DOORS REQUIRED MANUAL OPENING WITH ASSISTED BY MANIPULATION. ONCE THE DOORS WERE FREE THE NOSE GEAR IMMEDIATELY FELL TO THE DOWN AND LOCKED POSITION. POWER WAS APPLIED TO THE AIRCRAFT AND A THREE GREEN INDICATION WAS OBTAINED. THE AIRCRAFT WAS THEN PLACED ON THE RAMP ON THE LANDING GEAR. EVIDENCE OF THESE CONDITIONS CAN BE SEEN AT THE GSO FAA FSDO CASE FILE ACCIDENT ^PRIVACY DATA OMITTED^..
