Autopilot issues caused Aug. 24 Air Inuit flight to pitch: reports

“I was prepared to die. It was very scary, people screaming, crying, praying, food, papers, people flying in the plane”

More details about what happened on Saturday, Aug. 24, aboard an Air Inuit Boeing 737-200 aircraft en route from Montreal to La Grande have surfaced.

That’s although Air Inuit has not yet filed an occurrence report on Transport Canada’s Civil Aviation Daily Occurrence Reporting System about the incident or made any official statement about the incident.

Online websites dedicated to aviation incidents now suggest an autopilot malfunction on the 38-year-old aircraft was the cause of a wrenching upset that threw passengers, crew and meals around, and injured at least one person badly enough that an ambulance was required in La Grande.

Aviation Herald  reports that the Air Inuit Boeing 737-200, registration C-GSPW, was on its scheduled flight 3H-704 from Montreal to La Grande Rivière with 35 passengers and four crew on board.

But about 10 minutes after reaching a cruising altitude of 34,000 feet (about 10,300 metres) with the autopilot engaged, the aircraft suddenly pitched up.

A pitch motion is an up or down movement of the nose of the aircraft caused by a rapid change in altitude, which is different from the motion caused by turbulence, or a disturbance of air flow.

The crew disconnected the autopilot, noticed vibrations and buffeting in the flight controls and returned the aircraft to 34,000 feet (or about 10,300 metres) in altitude.

The crew then requested a block altitude from air traffic control, to allow the aircraft to find stability in a certain block of airspace.

The crew then re-engaged the autopilot, which resulted in a second uncontrolled pitch up, the Aviation Herald said.

The crew disconnected the autopilot again, and requested clearance to descend to 32,000 feet (or about 9,700 metres).

When it’s working well, the autopilot is a system that controls an aircraft’s path without constant hands-on control by a pilot.

But, when an autopilot fails, a crew member must disengage the system, either by flipping a power switch off or, if that doesn’t work, by pulling the autopilot circuit breaker.

Only passenger sustained injuries in one of the upsets, despite initial reports of multiple injuries.

But passengers on the flight say it was terrifying.

Photos shared with Nunatsiaq News show food thrown around the cabin, a seat torn off and blood on the arm of a chair.

“I was in that flight going back home it was very scary. I really thought I was going to die. I thought of my family, my children who’s waiting for me to come home. I was prepared to die. It was very scary, people screaming, crying, praying, food, papers, people flying in the plane,” said one passenger, who thanked God and the pilots, adding they were lucky to land in La Grande.

The crew requested an ambulance meet the aircraft at La Grande Riviere.

In the meantime, two nurses on board the aircraft helped the injured passenger, the Aviation Herald said.

The aircraft landed at its destination without further incident.

An earlier version of this story attributed a quote to a passenger on 3H-704. At the passenger’s request, we have removed his name, due to their fear of the consequences of having their name published.

    This happened in uncontrolled airspace. Air Inuit doesn’t need to report it.

      They were in controlled airspace. Even if they weren’t, it still needs to be reported

        Doesn’t matter what type of airspace it was in…incedents/accidents must be reported.

    Cudos to the pilots for landing safely in such difficult circumstances. I’m sure it was a great fright for everyone on board but thankfully the pilots landed safely and everyone walked away.

    Just for youre information Miss George, the incident has been reported to TSB and a CADORS will appear very shortly as it takes a few day to update the database. Knowing the two pilots I know they did everything in their possible to avoid these issues. Also I am sure they reported the incident as its mandantory.

    A reminder to always wear youre seatbelts when flying!!!

    I am thankfuk that everyone is safe and the pilots seemed to have been up to task,what is astounding is that this reporter is getting pushback for reporting a very important story,this chronic defensiveness and reactivity that permeates Nunavik institutions is an impediment to change,having worked in risk analysis I know that airplanes are safe because each incident that occurs catastrophic or minor is fully analyzed and investigated,thank you Ms. George

    This is an illustration as to how important it is to remain seated with the seatbelt buckled. Aircarfts are essentially safe and stable but unexpected occurrences can happen anytime and the radar or ATC cannot always detect heavy turbulence early enough to warn passengers. Malfunctions aren’t uncommon but the onboard safety devices ensure that most of those malfunctions aren’t dangerous to the crew and passengers but they may make the ride much more bumpy than usual. It’s good to keep that in mind when traveling on an airplane.
