Aviation Accident Final Report - National Transportation Safety Board:

Investigation Docket - National Transportation Safety Board:

Location: Sandy Valley, NV 
Accident Number: GAA19CA242
Date & Time: 05/05/2019, 0800 PDT
Registration: N175LM
Aircraft: Flight Design CTLS
Aircraft Damage: Substantial
Defining Event: Hard landing
Injuries:2 None 
Flight Conducted Under: Part 91: General Aviation - Instructional


The pilot reported that, during a biennial flight review, the flight instructor told him to expect a simulated engine failure during takeoff and an engine-out approach to a perpendicular runway. After departure and about 400 ft above ground level (agl), the instructor reduced power, and the pilot turned left to land on the perpendicular runway. He overshot the runway, banked to 40°, and felt a "strong sink." He leveled the wings and added full power about 150 to 200 ft agl, but the airplane continued to descend. The instructor stated he considered taking the flight controls, but the pilot maintained control. The airplane landed hard, the right main landing gear (MLG) struck a hole, the airplane veered right, and the left MLG separated.

The airplane sustained substantial damage to the fuselage.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's steep bank turn at low altitude, which resulted in a rapid descent and hard landing.
