Aircraft Accident/Incident Report
Charlotte, North Carolina 28208
Sunday, May 1, 1994 13:09 EDT
NTSB Narrative Summary Released at Completion of Accident
THE FLIGHTCREW REPORTED THAT WHILE EXTENDING THE LANDING GEAR, THE NOSE GEAR DID NOT INDICATE DOWN AND LOCKED. AFTER FURTHER ATTEMPTS TO LOWER THE NOSE GEAR WERE UNSUCCESSFUL, THE AIRCRAFT WAS LANDED WITH THE NOSE GEAR NOT DOWN AND LOCKED. INSPECTION REVEALED THAT THE NOSEWHEEL STEERING SYSTEM WAS INCORRECTLY RIGGED; THE NOSE GEAR WOULD NOT PROPERLY CENTER ITSELF, AND THE NOSEWHEEL STEERING CABLE TENSIONS WERE BELOW REQUIRED LIMITS. THIS RESULTED IN A SITUATION WHERE THE NOSE GEAR WOULD IMPINGE ON THE SIDE WALL OF THE GEAR WELL, PREVENTING EXTENSION. THE AIRCRAFT MANUFACTURER REPORTED THAT IT REQUIRED A COMBINATION OF NOSE GEAR MISRIGGING, WITH REDUCED CABLE TENSIONS, TO DUPLICATE THIS SCENARIO. ABOUT TWO WEEKS PRIOR TO THE INCIDENT, THE NOSEWHEEL STEERING CONTROL VALVE WAS REPLACED, WHICH WOULD HAVE REQUIRED A CHECK OF THE NOSE GEAR RIGGING.
NTSB Probable Cause Narrative
THE IMPROPER RIGGING OF THE NOSE WHEEL STEERING SYSTEM BY COMPANY MAINTENANCE PERSONNEL.
