A PIPER SENECA ON CLB OUT AT 2000 FT HAD LNDG GEAR FAILURE. MAIN GEAR NOT FULLY RETRACTED AND NOSE GEAR DOWN WITH NO POSITION INDICATION. CAUSED BY BARE CTL WIRING ON NOSE GEAR.

Narrative

FIRST FLT AFTER ANNUAL INSPECTION. ON CLB-OUT; NOTICED REDUCED PERFORMANCE; AND 'DOWN' NOSEWHEEL IN MIRROR. LIGHTS OUT ON PANEL INDICATING THAT GEAR HAD BEEN RAISED. CONTACTED ZZZ TWR. OVERFLEW TWR TO CONFIRM (I HAD RECYCLED GEAR-NO GREENS-AND GEAR PUMP CTL CB HAD POPPED) NOSE GEAR DOWN; MAIN GEAR NOT DOWN. EXECUTED EMER GEAR DOWN PROCEDURE. FLY OVER TWR CONFIRMED ALL GEAR DOWN. NO GEAR LIGHTS. RECYCLE OF CB WAS NOT SUCCESSFUL. WITH EXCELLENT HELP FROM TWR SET UP FOR POSSIBLE GEAR UP LNDG-TOUCH DOWN SUCCESSFUL; GEAR WAS LOCKED DOWN. STILL NO GREEN LIGHTS; CB STILL POPPED. SUBSEQUENT INSPECTION REVEALED BARE WIRES IN GEAR WELL THAT TOUCHED WHEN GEAR WAS COMING UP-SHORTED THE ELECTRICAL CIRCUIT FOR GEAR LIGHTS AND ACTUATORS; ACCORDING TO MECH. I KNEW THE GEAR HAD BEEN FULLY CHECKED FOR EMER OPERATION; AND I WAS REASONABLY CONFIDENT GEAR WAS DOWN AND LOCKED. THERE ARE 2 CB'S FOR THE GEAR CTL PUMP-ONE FOR ELECTRICAL AND ONE FOR PUMP. PUMP WAS OK; ELECTRICAL WAS POPPED. WHEN OPENING DOOR ON FINAL; WAS STARTLED BY THE EFFECT ON CTL OF ACFT-HAD NOT EXPERIENCED THAT BEFORE; EVEN WITH OCCASIONAL EXPERIENCE WITH 'OPEN' DOOR ON TKOF OR CRUISE. LANDED GENTLY AND UNDER CTL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE AIRPLANE WAS JUST OUT OF AN ANNUAL INSPECTION WHERE THE LNDG GEAR WAS OPERATED TO CHECK THE WORK DONE ON THE EMER EXTENSION. THE RPTR SAID THE NOSE GEAR CTL AND INDICATION WIRING LOCATED ON THE NOSE GEAR HAD TWO WIRES WITH INSULATION RUBBED OFF. THE RPTR STATED DURING THE NOSE GEAR RETRACTION THE WIRES SHORTED AND TRIPPED THE CB FOR THE ACTUATORS AND POSITION INDICATION. THE RPTR SAID THE TECHNICIAN WHO FOUND THE WIRING FAULT DID NOT INDICATE THIS TO BE A FREQUENT FAULT ON THIS TYPE AIRPLANE. THE RPTR STATED AN EMER WAS DECLARED AND ON LNDG EMER EQUIP WAS STANDING ON THE TXWY.
