From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry 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.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

On above date and time, PIC james was performing stall maneuvers in his experimental cozy mark 1V aircraft N68TF, within the northwest practice area. Stalls were being performed in order to determine if the canard elevator authority was operating according to specifications, and in order to make appropriate adjustments if necessary. These possible adjustments if made, would be to slow the aircrafts approach speed for landing purposes. During his last stall maneuver, from an altitude of 7,000 feet MSL, or 3,200 feet AGL, the main wing stalled prior to the canard stalling and resulted in loss of aircraft control. The aircraft stall/descent rate was indicated at approximately 200 feet per minute at the time of impact. Aircraft control was never regained throughout the maneuver, and the aircraft impacted the desert terrain in a nose high attitude. According to the owner, the aircraft was a total loss. Investigation ongoing. To be ammended.

As the FAA filed it

ON ABOVE DATE AND TIME, PIC JAMES WAS PERFORMING STALL MANEUVERS IN HIS EXPERIMENTAL COZY MARK 1V AIRCRAFT N68TF, WITHIN THE NORTHWEST PRACTICE AREA. STALLS WERE BEING PERFORMED IN ORDER TO DETERMINE IF THE CANARD ELEVATOR AUTHORITY WAS OPERATING ACCORDING TO SPECIFICATIONS, AND IN ORDER TO MAKE APPROPRIATE ADJUSTMENTS IF NECESSARY. THESE POSSIBLE ADJUSTMENTS IF MADE, WOULD BE TO SLOW THE AIRCRAFTS APPROACH SPEED FOR LANDING PURPOSES. DURING HIS LAST STALL MANEUVER, FROM AN ALTITUDE OF 7,000 FEET MSL, OR 3,200 FEET AGL, THE MAIN WING STALLED PRIOR TO THE CANARD STALLING AND RESULTED IN LOSS OF AIRCRAFT CONTROL. THE AIRCRAFT STALL/DESCENT RATE WAS INDICATED AT APPROXIMATELY 200 FEET PER MINUTE AT THE TIME OF IMPACT. AIRCRAFT CONTROL WAS NEVER REGAINED THROUGHOUT THE MANEUVER, AND THE AIRCRAFT IMPACTED THE DESERT TERRAIN IN A NOSE HIGH ATTITUDE. ACCORDING TO THE OWNER, THE AIRCRAFT WAS A TOTAL LOSS.
