UNSAFE GEAR COLLAPSED LANDING. NO BRAKES. OVERRAN RUNWAY. NEWLY PAINTED AIRCRAFTS GEAR AND BRAKES FOULED BY PAINT. (.19) ON JULY 5, 1997, AT 1700 CENTRAL DAYLIGHT TIME, A NORTH AMERICAN NA-265-80 AIRPLANE, N100EJ, WAS SUBSTANTIALLY DAMAGED WHEN THE RIGHT MAIN LANDING GEAR COLLAPSED DURING THE LANDING ROLL ON RUNWAY 13 AT THE ARDMORE MUNICIPAL AIRPORT, IN ARDMORE, OKLAHOMA. THE AIRLINE TRANSPORT RATED PILOT IN COMMAND (PIC) AND COPILOT WERE NOT INJURED. THE AIRPLANE WAS REGISTERED TO AND OPERATED BY SILVER LINING AVIATION LLC OF WESTLAKE, OHIO. VISUAL METEOROLOGICAL CONDITIONS PREVAILED AND AN IFR FLIGHT PLAN WAS FILED FOR THE CROSS COUNTRY POSITIONING FLIGHT WHICH DEPARTED ARDMORE APPROXIMATELY 1645 WITH AN INTENDED DESTINATION OF CLEVELAND, OHIO. IN HIS INITIAL REPORT OF THE ACCIDENT TO THE FAA, THE PILOT STATED THAT AFTER TAKEOFF HE NOTICED THE INSTRUMENTS INDICATED A LANDING GEAR PROBLEM. HE RETURNED TO THE AIRPORT FOR LANDING, AND WHEN THE GEAR WAS LOWERED, THE GREEN LIGHT FOR THE RIGHT MAIN GEAR DID NOT ILLUMINATE. A FLYBY OF THE CONTROL TOWER WAS PERFORMED, AND THE TOWER CONTROLLER ADVISED THE PILOT THAT THE LANDING GEAR APPEARED TO BE EXTENDED. DURING THE LANDING ROL L, THE RIGHT MAIN LANDING GEAR COLLAPSED, AND THE AIRPLANE SLID TO A STOP. EXAMINATION OF THE AIRPLANE BY THE FAA INSPECTOR REVEALED THAT THE OUTBOARD 6 TO 7 FEET OF THE LOWER RIGHT WING SKIN WAS DAMAGED TO A DEGREE REQUIRING MAJOR REPAIR. (.4) PRIOR TO THE ACCIDENT FLIGHT, THE AIRPLANE WAS COMPLETELY STRIPPED AND REPAINTED BY A MAINTENANCE FACILITY AT THE DEPARTURE AIRPORT. WHEN THE GEAR WAS RETRACTED AFTER TAKEOFF, THE PILOT NOTICED THAT THE LANDING GEAR WARNING LIGHT WAS ILLUMINATED. HE LOWERED THE LANDING GEAR, AND THE DOWN AND LOCKED INDICATOR LIGHT FOR THE RIGHT MAIN GEAR DID NOT ILLUMINATE. EMERGENCY GEAR EXTENSION PROCEDURES DID NOT CORRECT THE DISCREPANCY. THE PILOT ELECTED TO RETURN TO THE AIRPORT AND DECIDED NOT TO USE THRUST REVERSERS DURING THE LANDING ROLL TO MINIMIZE YAW. THERE WAS 'NO SIGNIFICANT PEDAL PRESSURE' WHEN HE APPLIED BRAKES FOLLOWING TOUCHDOWN, AND THE AIRPLANE OVERRAN THE RUNWAY. THE RIGHT MAIN LANDING GEAR COLLAPSED, AND THE RIGHT WING CONTACTED THE GROUND. EXAMINATION REVEALED THAT THE MAIN GEAR DOWNLOCK PINS HAD BEEN PAINTED WHICH RESULTED IN THE RIGHT PIN STICKING IN THE RETRACTED (UNLOCKED) POSITION WHEN THE GEAR WAS RAISED AFTER TAKEOFF. A DDITIONALLY, THE POWER BRAKE VALVE PISTONS HAD BEEN PAINTED WHICH RESULTED IN THE LEFT PISTON STICKING IN THE EMERGENCY (POWER OFF) POSITION WHEN THE PILOT TESTED THE EMERGENCY BRAKES BEFORE TAKEOFF. (-23) AFTER DEPARTURE FROM ARDMORE MUNICIPAL AIRPORT, THE RIGHT MAIN GEAR LIGHT DID NOT INDICATED AN UP AND LOCKED CONDITION. THE CREW WORKED THE GEAR AND PERFORMED AN EMERGENCY EXTENSION. THE GEAR LIGHT DID NOT INDICATE DOWN AND LOCKED. THEY LANDED THE AIRCRAFT. THE PILOT STATED THEY HAD A PROBLEM WITH THE BRAKES. THE AIRCRAFT WENT OFF THE END OF THE RUNWAY, THE RIGHT MAIN GEAR COLLAPSED AND THE AIRCRAFT CAME TO A STOP ABOUT 200 FEET BEYOND THE END OF THE RUNWAY. ## The NTSB's investigation of this event (1) From the NTSB's public API.
