Piper PA28R accident near Englewood, Colorado, August 8, 2020

On August 8, 2020 at about 5:00 pm local time, a 1970 Piper PA28R, registered N4964S, was substantially damaged in an accident during landing (flare/touchdown) near Englewood, Colorado (Centennial Airport). It was an instructional flight under general aviation rules (Part 91). No one was hurt; 2 people were on board or involved. The weather was visual conditions (good weather).

The NTSB's probable cause their words, unchanged

The flight instructor did not maintain a proper approach path and landing flare during a landing with a tailwind, which resulted in a hard landing and damaged landing gear. During the subsequent landing with damaged landing gear, the flight instructor lost directional control which resulted in a runway excursion and collision with objects.

The NTSB's narrative final · quoted from the NTSB record

The flight instructor was demonstrating a short approach and touch-and-go landing to the student pilot in a complex airplane. During the final approach, the flight instructor was unable to correct for a quartering tailwind and the airplane landed sideways on the left main landing gear. The flight instructor stated that "[the landing] felt a bit unusual, but the approach had been stable and the landing wasn't that bad..." The airplane took off and the landing gear would not retract. After troubleshooting the problem and declaring an emergency, the flight instructor landed the airplane with an unsafe landing gear indication. After touchdown, the left main landing gear collapsed, and the flight instructor lost directional control. The airplane impacted taxiway lights and came to rest upright adjacent to the runway. Postaccident examination showed the airplane sustained substantial damage to the left wing. Further examination of the left main landing gear and wing revealed overload damage to the landing gear wing attachment. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
