What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
At approximately 1912 EDT on may 25, 2022, N33LB experienced a gear collapse on runway 6 at Spruce Creek airport (private). Spruce Creek airport operations notified the FAA roc immediately following the event.
On may 29, 2022 the hired mechanic (IA) assessed the damage to the aircraft and determined that damage was limited to the props, landing gear, belly, and flaps of the aircraft. The resulting damage was considered to be caused by ground impact.
The PIC stated that prior to attempting to land, a "gear unsafe" indication was noticed. The pilot elected to depart the airport environment to begin running checklists. The checklist instructed the pilots to utilize the manual handcrank to lock the gear in the down position, by turning the handcrank 50 times. The pilot stated that after turning the handcrank the recommended 50 times, no change in the gear indication was noticed. The PIC turned the handcrank "an additional 250 times, with no change in indication noticed".
The PIC stated "a return to the departure airport commenced after notifying ground personnel of the situation and to observe the landing gear while a low approach was conducted to ascertain gear positioning. The low fly by resulted in the ground observers noticing that all three landing gear appeared to be down and in position. No green down and locked indications observed in the cockpit."
Upon landing, the PIC stated the following: "as the nose gear made contact with the runway it gave way and retracted into the nose gear area followed by the left main and propeller contact on the left side. Directional control was maintained by the PIC until the plane slowly began to turn left towards the left side of the runway at which point the nose was full down causing the right propeller to contact the ground. Near the edge of the runway the airplane stopped with a slight right side load which appeared to cause the right gear to collapse into the wheel well. "
The inspector in charge of the investigation was able to corroborate the flight activity and low pass by reviewing ADS-B data of the flight in question.
A review of pilot and aircraft qualifications was conducted to find no regulatory non-compliance.
As the FAA filed it
AT APPROXIMATELY 1912 EDT ON MAY 25, 2022, N33LB EXPERIENCED A GEAR COLLAPSE ON RUNWAY 6 AT SPRUCE CREEK AIRPORT (PRIVATE). SPRUCE CREEK AIRPORT OPERATIONS NOTIFIED THE FAA ROC IMMEDIATELY FOLLOWING THE EVENT.
ON MAY 29, 2022 THE HIRED MECHANIC (IA) ASSESSED THE DAMAGE TO THE AIRCRAFT AND DETERMINED THAT DAMAGE WAS LIMITED TO THE PROPS, LANDING GEAR, BELLY, AND FLAPS OF THE AIRCRAFT. THE RESULTING DAMAGE WAS CONSIDERED TO BE CAUSED BY GROUND IMPACT.
THE PIC STATED THAT PRIOR TO ATTEMPTING TO LAND, A "GEAR UNSAFE" INDICATION WAS NOTICED. THE PILOT ELECTED TO DEPART THE AIRPORT ENVIRONMENT TO BEGIN RUNNING CHECKLISTS. THE CHECKLIST INSTRUCTED THE PILOTS TO UTILIZE THE MANUAL HANDCRANK TO LOCK THE GEAR IN THE DOWN POSITION, BY TURNING THE HANDCRANK 50 TIMES. THE PILOT STATED THAT AFTER TURNING THE HANDCRANK THE RECOMMENDED 50 TIMES, NO CHANGE IN THE GEAR INDICATION WAS NOTICED. THE PIC TURNED THE HANDCRANK "AN ADDITIONAL 250 TIMES, WITH NO CHANGE IN INDICATION NOTICED".
THE PIC STATED "A RETURN TO THE DEPARTURE AIRPORT COMMENCED AFTER NOTIFYING GROUND PERSONNEL OF THE SITUATION AND TO OBSERVE THE LANDING GEAR WHILE A LOW APPROACH WAS CONDUCTED TO ASCERTAIN GEAR POSITIONING. THE LOW FLY BY RESULTED IN THE GROUND OBSERVERS NOTICING THAT ALL THREE LANDING GEAR APPEARED TO BE DOWN AND IN POSITION. NO GREEN DOWN AND LOCKED INDICATIONS OBSERVED IN THE COCKPIT."
UPON LANDING, THE PIC STATED THE FOLLOWING: "AS THE NOSE GEAR MADE CONTACT WITH THE RUNWAY IT GAVE WAY AND RETRACTED INTO THE NOSE GEAR AREA FOLLOWED BY THE LEFT MAIN AND PROPELLER CONTACT ON THE LEFT SIDE. DIRECTIONAL CONTROL WAS MAINTAINED BY THE PIC UNTIL THE PLANE SLOWLY BEGAN TO TURN LEFT TOWARDS THE LEFT SIDE OF THE RUNWAY AT WHICH POINT THE NOSE WAS FULL DOWN CAUSING THE RIGHT PROPELLER TO CONTACT THE GROUND. NEAR THE EDGE OF THE RUNWAY THE AIRPLANE STOPPED WITH A SLIGHT RIGHT SIDE LOAD WHICH APPEARED TO CAUSE THE RIGHT GEAR TO COLLAPSE INTO THE WHEEL WELL. "
THE INSPECTOR IN CHARGE OF THE INVESTIGATION WAS ABLE TO CORROBORATE THE FLIGHT ACTIVITY AND LOW PASS BY REVIEWING ADS-B DATA OF THE FLIGHT IN QUESTION.
A REVIEW OF PILOT AND AIRCRAFT QUALIFICATIONS WAS CONDUCTED TO FIND NO REGULATORY NON-COMPLIANCE.
