Diamond DA-20, N992CT: Accidents occurred June 16, 2018 and December 02, 2016



Aviation Accident Final Report - National Transportation Safety Board 

The National Transportation Safety Board did not travel to the scene of this accident.

Additional Participating Entity:

Investigation Docket - National Transportation Safety Board:

992CT Aircraft Leasing LLC


Location: Spanish Fork, Utah
Accident Number: GAA18CA358
Date and Time: June 16, 2018, 10:22 Local 
Registration: N992CT
Aircraft: DIAMOND AIRCRAFT IND INC DA 20 
Aircraft Damage: Substantial
Defining Event: Aerodynamic stall/spin
Injuries: 2 None
Flight Conducted Under: Part 91: General aviation - Instructional

Analysis

The flight instructor and pilot receiving instruction reported that the pilot performed a soft-field takeoff, and once in ground effect, he reduced back pressure, and the instructor heard the stall warning horn and observed a low airspeed. The instructor told the pilot to reduce the pitch, the pilot lowered the nose a little, but the airplane continued to climb. The instructor told the pilot to reduce pitch again, but the pilot stated he was concerned about a possible propeller strike. The flight instructor took the flight controls, but the airplane had turned to the right, and he experienced a "loss of control." The airplane landed off the right side of the runway, the instructor reduced power, the left main landing gear separated, and the airplane came to rest.

The flight instructor and pilot reported that the airplane had aerodynamically stalled.

The airplane sustained substantial damage to the fuselage.

The flight instructor and pilot both 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 receiving instruction's failure to maintain adequate airspeed and his exceedance of the airplane's critical angle of attack during takeoff, which resulted in an aerodynamic stall.

Findings

Aircraft Angle of attack - Capability exceeded
Personnel issues Aircraft control - Student/instructed pilot
Aircraft Airspeed - Not attained/maintained

Aircraft Damage: Substantial
Defining Event: Fuel exhaustion
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Instructional

Analysis 

The solo student pilot reported that, while on a cross-country flight, the weather deteriorated at the destination airport. He decided to complete a touch-and-go landing at an airport along the route and then return to the departure airport. The student pilot further reported that, when he began the flight back to his original point of departure, the airplane had about 3/4 tank of fuel remaining, and a headwind was present. About 10 to 15 nautical miles from the original departure airport, the fuel supply was exhausted, and the student pilot made a forced landing in a field. During the forced landing, the right wing struck a tree and was substantially damaged.

The student pilot did not report any preaccident mechanical malfunctions or failures 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 student pilot's improper in-flight fuel planning, which resulted in fuel exhaustion.
