## Probable cause

The pilot's failure to maintain adequate airspeed during landing, which resulted in a stall.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

## Analysis

The pilot reported that he was landing after a local flight. He stated that during the landing flare he “stalled the plane about 10 feet AGL [above ground level].” The airplane sustained substantial damage when the right wing tip contacted the ground. The pilot performed a go-around and the airplane's left wing contacted the runway during the go-around. The pilot’s accident report listed no pre-impact mechanical malfunctions with the airplane.

## Factual narrative

The pilot reported that he was landing after a local flight. He stated that during the landing flare he “stalled the plane about 10 feet AGL [above ground level].” The airplane sustained substantial damage when the right wing tip contacted the ground. The pilot stated that he did not know that the right brake system had been damaged. The airplane exited the runway and the pilot added power to gain airspeed. The left wing contacted the runway. The pilot requested a go-around. The second attempt to land was uneventful “without further damage to the aircraft.” The air traffic controller requested that the pilot make a 180-degree turn and taxi to the ramp. As the pilot stopped, he realized that he did not have right brakes and reported it to the air traffic controller. The pilot’s accident report listed no pre-impact mechanical malfunctions with the airplane.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 20100630039549A](https://openairdocs.org/incident/20100630039549A), Jun 30, 2010: Diamond Air DA 20-C1, Bloomington, IL, Substantial damage. Pilot reported right brake failure after landing. Subsequent inspection revealed the aircraft had a hard landing.

## Other investigations on N802CT (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

- [NTSB WPR20CA305](https://openairdocs.org/ntsb/WPR20CA305), Sep 11, 2020: Diamond DA20 (N802CT), Fillmore, UT, substantial damage. Probable cause: The student pilot's improper landing flare and delayed remedial action to abort the landing, which resulted in a loss of aircraft control, runway excursion and impact with terrain.
