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.

Practicing short field takeoffs flight instructor over applied brakes resluting in a noseover. (-23)aircraft nosed over during landing roll while practicing short field technique. PIC stated that she had applied what she considered adequate braking. The flight instructor then told her to brake harder, and he applied hard braking, causing aircraft to pitch forward onto nose. (.4) the pilot of the Aeronca 7AC was applying braking during a practice short-field landing. The instructor pilot in the back seat told her to apply more braking, but she did not apply as much as the instructor thought was appropriate. The instructor therefore elected to apply additional braking, whereupon the aircraft started to nose over. As soon as the nose-over started, the instructor pilot released the brake pressure he had applied, but it was too late to keep the aircraft's nose from hitting the runway and the main gear from lifting off the runway surface. After hitting the runway, the aircraft fell back onto its main landing gear with sufficient force to tear one main gear attach fitting from the fuselage.

As the FAA filed it

PRACTICING SHORT FIELD TAKEOFFS FLIGHT INSTRUCTOR OVER APPLIED BRAKES RESLUTING IN A NOSEOVER. (-23)AIRCRAFT NOSED OVER DURING LANDING ROLL WHILE PRACTICING SHORT FIELD TECHNIQUE. PIC STATED THAT SHE HAD APPLIED WHAT SHE CONSIDERED ADEQUATE BRAKING. THE FLIGHT INSTRUCTOR THEN TOLD HER TO BRAKE HARDER, AND HE APPLIED HARD BRAKING, CAUSING AIRCRAFT TO PITCH FORWARD ONTO NOSE. (.4) THE PILOT OF THE AERONCA 7AC WAS APPLYING BRAKING DURING A PRACTICE SHORT-FIELD LANDING. THE INSTRUCTOR PILOT IN THE BACK SEAT TOLD HER TO APPLY MORE BRAKING, BUT SHE DID NOT APPLY AS MUCH AS THE INSTRUCTOR THOUGHT WAS APPROPRIATE. THE INSTRUCTOR THEREFORE ELECTED TO APPLY ADDITIONAL BRAKING, WHEREUPON THE AIRCRAFT STARTED TO NOSE OVER. AS SOON AS THE NOSE-OVER STARTED, THE INSTRUCTOR PILOT RELEASED THE BRAKE PRESSURE HE HAD APPLIED, BUT IT WAS TOO LATE TO KEEP THE AIRCRAFT'S NOSE FROM HITTING THE RUNWAY AND THE MAIN GEAR FROM LIFTING OFF THE RUNWAY SURFACE. AFTER HITTING THE RUNWAY, THE AIRCRAFT FELL BACK ONTO ITS MAIN LANDING GEAR WITH SUFFICIENT FORCE TO TEAR ONE MAIN GEAR ATTACH FITTING FROM THE FUSELAGE.
