## Discrepancy

AIRCRAFT RETURNED TO FIELD WHEN THE LANDING GEAR FAILED TO RETRACT.  A FAILED S106 LANDING GEAR SAFETY SWITCH CAUSED THE AIRCRAFT TO REMAIN IN THE GROUND MODE, RESULTING IN THE GEAR FAILING TO RETRACT. THE S106 LANDING GEAR SAFETY SWITCH WAS REPLACED AND THE LANDING GEAR EXTENDED AND RETRACTED NORMAL.
