## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

ON AUGUST 15, 2015 AT APPROXIMATELY 1530 EST, N5620Q WAS PERFORMING ROUTINE PATTERN WORK WHEN IT WAS DISCOVERED THAT THE LANDING GEAR WOULD NOT EXTEND. AS A RESULT, THE PILOT HAD TO MAKE AN EMERGENCY LANDING AT NEWNAN-COWETA COUNTY AIRPORT (KCCO).  THE AIRCRAFT SUSTAINED MINOR DAMAGE WITH NO INJURIES REPORTED.  AN INSPECTOR FROM THE ATLANTA FSDO WAS DISPATCHED TO CONDUCT AN INVESTIGATION AS TO THE CAUSE OF WHY THE LANDING GEAR WOULD NOT EXTEND DURING LANDING.

DURING THE INTERVIEW WITH THE PILOT, HE STATED THAT HE WAS OUT PERFORMING PATTERN WORK AND UPON ENTERING DOWNWIND FOR LANDING ON RUNWAY 14 AT KCCO, IT WAS DISCOVERED THAT THE LANDING GEAR WOULD NOT EXTEND. HIS NEXT COURSE OF ACTION WAS TO PERFORM A MANUAL GEAR EXTENSION PROCEDURE AND NOTICED THE MANUAL GEAR CRANK HANDLE WOULD NOT ROTATE. THE PILOT NOTIFIED THE AIRPORT OF THE SITUATION AND PERFORMED AN EMERGENCY LANDING. HE WAS ABLE TO SLOW THE AIRCRAFT DOWN JUST ENOUGH TO ALLOW FOR A BELLY LANDING AND SLIDING TO A COMPLETE STOP.

ON AUGUST 17, 2015 INSPECTOR DAVIDSON TRAVELED TO NEWNAN-COWETA COUNTY AIRPORT (KCCO) TO MEET WITH THE IA MECHANIC THAT WOULD BE PERFORMING THE TROUBLESHOOTING OF N5620Q. THE INITIAL ASSESSMENT OF THE AIRCRAFT DISPLAYED MINOR SHEET METAL DAMAGE TO THE UNDER BELLY OF THE AIRCRAFT WITH THE MAJORITY OF THE DAMAGE TO THE NOSE WHEEL WELL DOORS. THE MECHANIC BEGAN THE TROUBLESHOOTING BY PLACING THE AIRCRAFT ON JACKS AND ATTEMPTING TO PERFORM A GEAR EXTENSION, WHICH WAS UNSUCCESSFUL.  THE NEXT STEP IN THE TROUBLESHOOTING PROCESS POINTED TOWARDS THE LANDING GEAR ACTUATOR WHICH WAS INSPECTED AND LUBRICATED DURING THE LAST ANNUAL INSPECTION PER MOONEY SBM20-190B. AN INSPECTION OF THE GEAR ACTUATOR REVEALED THAT THE MOONEY SB20-190-1 DUKES GEAR KIT INCLUDES A WORM GEAR AND DRIVE GEAR THAT IS ATTACHED TO A JACKSCREW SHAFT THAT MOVES FORWARD AND AFT TO RAISE AND LOWER THE LANDING GEAR. THESE GEARS WERE FOUND IN GOOD CONDITION, NO BINDING, AND PROPERLY GREASED WITH DUKE?S SPECIAL PURPOSE GREASE P/N 2196-74-1 PURCHASED AT LASAR. NEXT, THE GEARBOX THAT IS DIRECTLY CONNECTED TO THE ELECTRIC MOTOR WAS REMOVED AND FOUND TO BE IN GOOD CONDITION WITH NO BINDING. THE MECHANIC REMOVED THE MANUAL EXTENSION SLIDING MECHANISM MOUNTED TO THIS GEARBOX AND FOUND ITS OPERATION SATISFACTORY. FINALLY, THE LAST ITEM THAT WAS CHECKED WAS THE ELECTRIC MOTOR AND IT WAS DISCOVERED THE MOTOR SHAFT WAS FROZEN. WITH NOTHING ATTACHED TO THE ELECTRIC MOTOR SHAFT IT WOULD NOT ROTATE IN EITHER DIRECTION.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
