Carley McCord plane crash report reveals propeller problem

The Advocate (use incognito)
Investigators found evidence suggesting propellers on a small plane that crashed in Lafayette on Dec. 28, 2019, killing five people on their way to an LSU Peach Bowl game, weren't rotating as they should have been and there was abnormal drag on the aircraft.
One of the reports dated May 21, 2020, concludes there was more drag than normal on the airplane during its final descent. While the cause is unknown, the report suggests it "might result from drag on the propellers following a sudden reduction in power to the engines."
An April 30, 2020, report describes a sound analysis of surveillance video from two buildings the plane flew over just before crashing along with an analysis of the propellers. The report suggests the plane's propellers were not rotating at maximum speed.
Several witnesses said seconds before the crash it sounded like the engines were straining or losing power, while others said it sounded like the engines were going "full throttle" before the plane passed low over an apartment complex and struck power lines next to a post office on Feu Follet Road. The plane ultimately landed in a field where it broke up and caught fire.
Those on board included The pilot, Ian Biggs, 51, sat up front on the left. Robert Vaughn Crisp II, 59, Stephen Wade Berzas, Carley Ensminger, 30, Gretchen Vincent, 51; and her son, Michael Walker Vincent, 15
RIP to a sweet lady

I was thinking the same thing but that's how the article was titled

Also on board were my good friends Vaughn and Wade.
RIP Vaughn

Yep loved Carley. Remember when she came on Moscona's show for the first time. She was a dime. Never got a chance to meet her in person but she did sideline reporting for a few of the SLU football games too.

So it was sputtering like it was having fuel issues?
IE running out of fuel?

Because the engines didn't fail. There was increased drag due to a propler problem, thus causing more strain on the engines.

That's still so damned sad

remember when lots of people here were saying all kinds of nasty things because they filed a lawsuit?

I took it as a pitch problem with the propellers that caused a loss of thrust.

I updated the op. Sorry.

Hoping some turbine pilots on here can digress.
Wonder if the prop control (blue levers) next to throttle was set at wrong bite. You’d think this issue would be known on takeoff roll.

You have to file lawsuits
The investigation has to conclude though to figure out exactly who the responsible parties are and who insurance company is going to have to pay out
If it's pilot error than that would be part of the liability
If it's mechanic than the owner of the plane or who is responsible for maintaining plane would be the liability

What else would have put drag on the props? There wasn’t any ice that day. Bird strike?

I met her on a crash one afternoon on essen before she went on air. She was super nice and gave me a shout out on the radio after. Terrible thing to happen.

That plane almost certainly had variable pitch propellers. If there was a problem with the propeller pitch it could cause the propellers to lose efficiency no matter what the blade RPM was.

Trim problem? Bent prop? I don't know...

Gotcha.

I remember the visibility was bad that day, air around the airport was soupy and there was fog all around

The morning of the crash, there was low visibility — about three-fourths of a mile — and the cloud base began at about 200 feet, according to the National Transportation and Safety Board.
Biggs “lacked the experience and/or training to operate (the plane) in less than ideal meteorological conditions, as was the case on the date of the crash," Ensminger wrote in his lawsuit. Ensminger also claims the owners of the plane knew Biggs lacked the experience or training.
Biggs obtained his commercial pilot's license in 2005, according to Federal Aviation Administration records. The plane had its last maintenance check in October. It was last flown Dec. 18 from Houston, which is about a 40-minute flight. Biggs was the pilot on that flight.

On most variable-pitch propellers, the blades can be rotated parallel to the airflow to stop rotation of the propeller and reduce drag when the engine fails or is deliberately shut down. This is called feathering, a term borrowed from rowing. On single-engined aircraft, whether a powered glider or turbine-powered aircraft, the effect is to increase the gliding distance. On a multi-engine aircraft, feathering the propeller on an inoperative engine reduces drag, and helps the aircraft maintain speed and altitude with the operative engines.
Most feathering systems for reciprocating engines sense a drop in oil pressure and move the blades toward the feather position, and require the pilot to pull the propeller control back to disengage the high-pitch stop pins before the engine reaches idle RPM. Turboprop control systems usually utilize a negative torque sensor in the reduction gearbox which moves the blades toward feather when the engine is no longer providing power to the propeller. Depending on design, the pilot may have to push a button to override the high-pitch stops and complete the feathering process, or the feathering process may be totally automatic.

The propellers on some aircraft can operate with a negative blade pitch angle, and thus reverse the thrust from the propeller. This is known as Beta Pitch. Reverse thrust is used to help slow the aircraft after landing and is particularly advantageous when landing on a wet runway as wheel braking suffers reduced effectiveness. In some cases reverse pitch allows the aircraft to taxi in reverse – this is particularly useful for getting floatplanes out of confined docks.
