What was found
NOSE GEAR COLLAPSED ON LANDING. NLG ACTUATOR WAS REMOVED AND TESTED IN A CONTROLLED ENVIRONMENT. WHEN THE ACTUATOR WAS COLD SOAKED, THE SWITCH FAILED TO ACTIVATE PROPERLY GIVING A FALSE INDICATION THAT THE GEAR WAS DOWN AND LOCKED. DUE TO THE GEAR FAILURE, BOTH ACFT PROPELLERS STRUCK THE GROUND AND CAUSED SUDDEN STOPPAGE TO THE ENGINES. THE ACFT ALSO SUFFERED STRUCTURAL DAMAGE TO THE NOSE SECTION OF THE ACFT.
