Investigation Docket - National Transportation Safety Board:
Location: Fort Carson, Colorado
Accident Number: CEN22LA110
Date and Time: January 25, 2022, 07:28 Local
Registration: N974DA
Aircraft: DIAMOND AIRCRAFT IND INC DA20-C1
Aircraft Damage: Substantial
Defining Event: Windshear or thunderstorm
Injuries: 2 None
Flight Conducted Under: Part 91: General aviation - Instructional
Analysis
The flight instructor reported that he and the student pilot were conducting touch-and-go landings. As the pilot turned from base to final, a “fairly significant crosswind” that had shifted while they were in the traffic pattern, pushed the airplane left of the runway centerline. After realigning the airplane with the extended runway centerline, right aileron and “nearly full left rudder deflection” were required to stay on course. When the airplane was on short final, about 200 ft agl, it encountered windshear and descended rapidly impacting the ground about 200 ft short of the runway threshold. The airplane sustained substantial damage to the engine mounts. The pilots reported that there were no preaccident mechanical malfunctions with the airplane that would have precluded normal operation. The flight instructor reported that he took control of the airplane to initiate a go-around but was unable to arrest the descent before
ground impact. About the time of the accident, the student pilot was landing on runway 31 with wind from 360° at 9 knots.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The windshear encounter on short final approach, which resulted in an excessive decent rate and ground impact.
Findings
Environmental issues Windshear - Contributed to outcome
Environmental issues Windshear - Effect on equipment
Aircraft Descent rate - Not attained/maintained
Personnel issues Knowledge of meteorologic cond - Instructor/check pilot
Personnel issues Weather planning - Instructor/check pilot

At about 7:30 a.m., a Diamond DA20-C1 Eclipse landed short of a runway on Fort Carson. The civilian flight instructor and pilot under instruction, a member of the Air Force, were taken to Evans Army Medical Center on post “out of precaution,” according to Benjamin Faske, chief of public affairs for the 12th Flying Training Wing, out of Joint Base San Antonio-Randolph, Texas.
The 1st Flying Training Squadron, part of the 12th Flying Training Wing, provides flight training out of Pueblo Memorial Airport.
Next steps include an investigation into what happened and a damage assessment of the aircraft, which did not overturn, Faske said.
