Location: St. Louis, IL
Accident Number: GAA19CA279
Date & Time: 05/23/2019, 1410 CDT
Registration: N369PA
Aircraft: Guimbal CABRI
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Instructional 

The helicopter flight instructor reported that, during a training flight, he briefed the student pilot on the procedures required to land with a simulated stuck left pedal. The student began a descent to enter a shallower-than-normal glide path to the runway surface, and he completed his final checks for the maneuver and continued the approach.

Upon contacting the runway, the helicopter veered to the left, and the instructor elected to abort the landing. As the helicopter lifted off, it began to yaw to the left at a rapid rate, while drifting to the left of the runway. Recognizing the helicopter was in a spin, they attempted to correct by leveling the helicopter "long enough for the aircraft to regain tail-rotor authority." The helicopter's left skid impacted the mud on the left side of the runway and the helicopter rolled onto its left side.

The Federal Aviation Administration's Helicopter Flying Handbook, FAA-H-8083-21A, provides information and guidance in a section titled "Landing – Stuck Neutral or Right Pedal" which stated in part:

The landing profile for a stuck neutral or a stuck right pedal is a low-power approach terminating with a running or roll-on landing. The approach profile can best be described as a shallow to normal approach angle to arrive approximately 2–3 feet landing gear height above the intended landing area with a minimum airspeed for directional control.

During the approach the flight instructor directed the student pilot to "utilize throttle manipulation to control the yaw caused by a fixed input on the anti-torque system."

The manufactures service letter, SL 19-002 A, states, "During in-flight tail rotor control failure simulation, pilots should never use the twist grip to control yaw."

The helicopter sustained substantial damage to the main rotor, fuselage and tail-boom.

The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.

The automated weather observation station located on the airport reported that, about the time of the accident, the wind was variable at 4 knots.

CAHOKIA • A helicopter pilot and an aviation student escaped unharmed after their helicopter crashed Tuesday at St. Louis Downtown Airport. 

They were returning from a flight training session about 2:40 p.m when the helicopter crashed on the airport's secondary runway, said Patti Beck, a spokeswoman with Bi-State Development. Bi-State owns the airport.

The airport's secondary runway was closed after the crash. The primary runway remained open to air traffic.

Beck did not have more details. 

The helicopter had taken off from the airport shortly after 2 p.m. and flew about 25 miles over the Metro East, according to the online flight tracking site FlightAware. It was set to arrive at the airport at about 2:45 p.m. 

The Federal Aviation Administration was called to the scene to investigate the cause of the crash.
