Callback conversation with reporter revealed the following information: the reporter stated the aircraft was a canadair CL65 regional jet and the mechanics found a failed gear proximity sensor and also replaced a gear lock solenoid.
Original NASA ASRS Text
Title: A CANADAIR CL65 IMMEDIATELY AFTER TKOF DIVERTED DUE TO UNABLE TO RETRACT THE NOSE LNDG GEAR CAUSED BY A FAILED PROXIMITY SENSOR AND GEAR LOCK SOLENOID.
Narrative: NOSE GEAR DID NOT RETRACT. RETURNED TO CVG. MECHS DISCOVERED PROXIMITY SENSOR INOP. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ACFT WAS A CANADAIR CL65 REGIONAL JET AND THE MECHS FOUND A FAILED GEAR PROXIMITY SENSOR AND ALSO REPLACED A GEAR LOCK SOLENOID.
