## Narrative

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

UAS REGISTRATION NUMBER: FA3RHRCY49

OWNER: ASYLON ROBOTICS, NORRISTOWN PA

MODEL: FOXTECH HOVER 1

ON APRIL 20, 2022, AT 1017 EDT, REMOTE PILOT IN COMMAND (RPIC) ^PRIVACY DATA OMITTED^ COMMANDED UNMANNED AIRCRAFT TO ARM AND TAKEOFF WITH HEADING 060 IN STABILIZE MODE. THE TAKEOFF WAS APPROXIMATELY 35 SECONDS AFTER BOOT-UP, NOT PERMITTING THE AIRCRAFT?S GPS TO LOCK ON TO ITS LOCATION. APPROXIMATELY 8 SECONDS AFTER ARMING THE AIRCRAFT, THE RPIC INPUTTED A LEFT ROLL VIA THE RADIO CONTROLLER TO THE DRONE, CAUSING IT TO SHIFT AWAY FROM THE OPERATOR. OVER THE NEXT 10 SECONDS THE DRONE ASCENDED FROM 2 METERS TO 16 METERS, SURPASSING NORMAL TRAINING ALTITUDE.

APPROXIMATELY 14 SECONDS INTO FLIGHT, THE RPIC ATTEMPTED TO COMMAND THE DRONE INTO LOITER MODE, HOWEVER, THE DRONE REJECTED THE COMMAND DUE TO THE LACK OF GPS LOCATION LOCK REQUIRED TO TRANSITION INTO A GPS-ASSISTED FLIGHT MODE. OVER THE NEXT SIX SECONDS, THE RPIC

LOWERED THE THROTTLE AS THE AIRCRAFT CONTINUED TO DRIFT SEVERAL METERS OVER THE COMPANY'S PARKING LOT. WITH THE RPIC COMMANDING THE THROTTLE TO THE MINIMUM VALUE IN STABILIZE MODE, THE AIRCRAFT ACCELERATED TOWARD THE GROUND, FALLING 21 METERS BEFORE IMPACTING ANOTHER ASYLON EMPLOYEE?S VEHICLE CAUSING DAMAGE.

## NTSB investigation

None matched to this report by aircraft and date. Search the NTSB's own records: https://data.ntsb.gov/carol-main-public/basic-search

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.
