The pilot who reported the crash of a Canadian military helicopter was unaware of a flight control software conflict
The pilot of the ill-fated Canadian military helicopter that crashed in the Ionian Sea near Greece last year manually surpassed the aircraft’s automatic flight controller system, which caused an unexpected “deviation” in the electronic system of the CH-148 Cyclone. This is the end of the Air Force flight safety investigation.
The Air Force reported that it is a routine procedure to try manual control while the automated system is still working. But in this case, it forced the aircraft to dive directly into the sea when landing on HMCS Fredericton.
On April 29, 2020, the accident caused the death of 6 soldiers, which was the largest loss of life in the Canadian Armed Forces in a single day since the war in Afghanistan.
The victims were: Captain Brendon MacDonald, Captain Kevin Hagen, Captain Maxim Miron-Morin, Captain Captain. Matthew Cousins, deputy lieutenant. Matthew Parker and deputy lieutenant. Abigail Kubler.
The final flight safety investigation report was released on Monday, and no one was accused.
On the contrary, the report contains a number of mitigating factors that indicate system deficiencies.
The pilot did not realize the problem
The report stated that it is “usual” for pilots to try to pilot the helicopter manually when the automatic flight controller is activated, and the flight manual that may solve this problem “may be confusing or misleading.”
In addition, the computer “may not sufficiently draw the pilot’s attention to the flight instructor [the automatic flight control system] Participated during the exercise. “
Essentially, the pilot was not warned of the problem before the tragedy happened.
The software repair of the flight control system is one of the recommendations put forward by the combat safety investigation.
Brig.-Gen said: “This accident was not caused by a single cause, but a combination of multiple factors, and could happen to any other crew member on any other day.” Air Force Flight Safety Director John Alexander said in a statement.
He added, “Before the accident, the manufacturer, airworthiness authority and crew were not aware of the failure.”
