Loss of Control in Flight: Zenith CH 750 STOL, N227L; accident occurred December 23, 2019 at Greene County - Lewis A. Jackson Regional Airport (I19), Xenia, Ohio

Aviation Accident Final Report - National Transportation Safety Board 

Additional Participating Entity:
Federal Aviation Administration / Flight Standards District Office; Cincinnati, Ohio

Investigation Docket - National Transportation Safety Board:

Location: Xenia, Ohio 
Accident Number: CEN20CA059
Date & Time: December 23, 2019, 15:04 Local 
Registration: N227L
Aircraft: Zenith CH 750
Aircraft Damage: Substantial
Defining Event: Loss of control in flight
Injuries: 1 None
Flight Conducted Under: Part 91: General aviation - Flight test


The pilot reported that the flight was the first flight of the experimental, amateur-built airplane. He stated that he was lined up with the runway centerline for landing, that the airspeed was 60 mph, and that the tachometer was showing 1,600 rpm when he felt the right tire contact the runway. He said "in an instant the left wing came down and the left tire and axle [were] sheared off. The left wing impacted the runway and the plane skidded about 40 feet and came to a full stop." The pilot used a higher landing airspeed because he had been told by other builders of that airplane that he needed to land with speed "so as not [to] get near the stall speed as this aircraft does have leading edge slats and this equates to a high lift wing." Postaccident examination of the airplane revealed that the nose landing gear and the left wing strut sustained substantial damage.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain airplane control during landing, which resulted in the right tire contacting the runway first followed by the left wing.

  1. No Loss here.

    These are cheap Pop-rivet disposable airplanes.
    Happy no one was injured.

  2. The Zenith aircraft models are most definitely NOT disposable airplanes, they are affordable and relatively easy to build and have great STOL/slow speed landing characteristics.
    Proper training of the pilot with this type of aircraft would possibly have prevented this mishap.

    Indeed happy nobody was injured.
