Location: Cahokia, IL
Accident Number: GAA18CA110
Date & Time: 01/22/2018, 1115 CST
Registration: N989HH
Aircraft: HELICOPTERES GUIMBAL CABRI G2
Aircraft Damage: Substantial
Defining Event: Loss of control in flight
Injuries: 2 Minor
Flight Conducted Under: Part 91: General Aviation - Instructional 

The helicopter flight instructor reported that, the student pilot was performing a normal approach to a hover with a quartering gusting headwind. He added that, he "reminded" the student of the need to anticipate right pedal input as they applied power to terminate to a hover. Subsequently, the student pilot did not add sufficient "right pedal", and the helicopter immediately and very rapidly yawed to the left. The flight instructor said, "my controls" and attempted to recover, but the helicopter continued to spin counterclockwise, touched down and rolled onto its right side.

The helicopter sustained substantial damage to the fuselage and main rotor system.

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

The automated weather observation system on the accident airport reported, about the time of the accident that the wind was from 170° at 11 knots, gusting to 22 knots. The student pilot attempted to hover on runway 12L.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The student pilot's failure to maintain yaw control while landing in gusting crosswind conditions and the flight instructor's delayed remedial action.

CAHOKIA, Ill. - The Federal Aviation Administration is investigating what caused a helicopter to crash Monday morning at the St. Louis Downtown airport. The helicopter landed on its roof before breaking into pieces.

Debris was scattered across the fields near the landing strip, but the two men inside walked out of the wreckage.

Fire officials say the crash happened around 11:14 a.m. at the airfield in Cahokia, Illinois. The cockpit remained intact but toppled on its side. The tail boom is clipped off and the propeller is in pieces.

The two men inside the chopper, believed to be a flying instructor and a student, climbed out on their own. This was a training flight with the Midwest Helicopter Training Academy.

A spokesperson with Jet Aviation at the airport said during training exercises they typically fly lower to the ground which may have lessened the impact in this case.

People working in the air traffic control tower saw the crash and alerted emergency workers.

“They were talking to our air traffic control tower, but they did not contact air traffic control tower as the crash happened. Air traffic control tower activated our alert tones as soon as they saw the crash," said Michael Mavrogeorge, the Fire Chief and Emergency Management Director of St. Louis Downtown Airport.

The men suffered minor cuts, bumps, and bruises. They were taken to Saint Louis University hospital to get checked out.

Fox 2 and KPLR 11 reached out to the Midwest Helicopter Academy for comment but they declined since the crash is under investigation.

CAHOKIA • Two people were able to climb out of a training helicopter after it crashed at St. Louis Downtown Airport in Cahokia on Monday morning.

The two people inside were taken to SSM Health St. Louis University Hospital with minor injuries after the crash at about 11:15 a.m.

"Minor injuries. Very lucky," said Chief Michael Mavrogeorge of the airport's fire department. "There was no fire after the aircraft crashed."

On board were an instructor and a student, KTVI reported. Mavrogeorge did not immediately have information about the occupants.

The airport is about four miles southeast of downtown St. Louis. Mavrogeorge said the control tower dispatched his crew to the crash, and arriving firefighters found the helicopter on its roof with two people climbing out.

The Federal Aviation Administration will investigate the crash, Mavrogeorge said.
