PC-12 Medevac Broke Up, Five Killed (Updated) - AVweb

Maybe another one of those untracked balloons that are so prevalent now.

Russ, you do a great job, but this report is very misleading. Please watch the various videos available online with the flight radar profile of this flight. This airplane did not break up at FL19 in normal flight. This pilot lost control in IMC—perhaps due to spatial disorientation and task saturation—most likely after the autopilot was disengaged or disengaged itself in challenging conditions. Parts falling off the plane virtually certainly did not cause this crash. The parts were found quite close to the main wreckage. So they most likely fell off during the last part of the incredibly fast plummet to earth due to excessive speed, excessive g load, or both, long after positive control of the aircraft was lost by the pilot. The general public will believe based on your report and others that this PC12 was just flying along, started shedding parts due to turbulence or something, and then crashed as a result. Not true! And this feeds unwarranted fears among the general public of commercial planes breaking up in normal flight, which is vanishingly rare. Please edit your report to reflect what the radar data and location of the separated parts strongly indicates about when they left the aircraft. Thanks. Keep up the good work.

“The NTSB says a Pilatus PC-12 medevac aircraft broke up in flight shortly after taking off from Reno Airport on Friday night.

Both the headline and this opening paragraph are extremely misleading, for starters. The aircraft did not just ‘break up’ spontaneously shortly after takeoff. Imho it’s irresponsible to report news like this.

I wonder how well instrument qualified pilots can actually fly with basic instruments? I have personally spent the most rewarding moments in the air in a glider in the clouds with only a clock, yaw and tilt, variometer and altimeter as help. I got the speed information from the sounds of the air flow, because the pitot tube is the first to freeze. I have had some flights in autumn when the last ice comes off the wings in the finale.

“ generalized light to moderate turbulence”

“ the NTSB said there had been no reports that would have warranted cancelling the flight.”

“It was pretty much a normal evening,”

These are “earmarks of a pilot killer”?

Broke up climbing to altitude OR broke up in an uncontrolled dive (overspeed)???

Not enough coherent information here to understand what really happened.

In a word, no. You’re asking me to analyze and reach conclusions on the cause of the accident and I’m neither qualified nor do the resources you cite contain all the information needed to reach those conclusions. We present hard facts as they become available and never speculate on cause. Anything else is irresponsible guesswork.

I guess it depends on your definition of “shortly.” And nowhere does it say the plane broke up “spontaneously.” The story accurately reports the facts of this accident although more information is available now than at time of writing. Instead of “shortly” I could have given a more precise timeline.

The average non-pilot–and non-pilot reporters who will parrot you–may very well believe you are saying that the ‘breakup shortly after t/o’ caused the crash, which is implied though not stated. (I have seen it out there already.) I guess we will just agree to disagree, but I think this report does a disservice to aviation in the public consciousness.

Another site I saw indicated the pilot was very experienced. Who knows but it could have been overloaded with ice with subsequent loss of control or the pilot suffered incapacitation. The breakup apparently happened during high speed/high g descent. Tail plane and right wing were found apart from the main wreckage.

Reminds me of a PC-12 break-up over Morristown, NJ some years ago. NW winds from the Great Lakes near freezing at the surface, and icing reports and pilots begging for altitude changes.
Reading between the lines it was a personal flight with family and a friend from MMU to spend Christmas in Georgia which I believe is about the range of this plane.
Assuming he’s heavy and digging hard for altitude to make Georgia without an extra stop. During climb and at about 17k ft accident pilot told ATC the conditions were not a problem when the aircraft suddenly started down never regaining control. Plopped down on I-287 with some important parts strewn in the trees. It too happened SHORTLY after takeoff, during climb out.

Is it legal to fly a non IFR glider in IMC? In known ice?

I’d not post that on a public forum if it is not…

What a sad commentary. The facts, -–––––– It was a PC12, it reached FL190 and at this stage, anything else is sheer speculation which is neither helpful nor an expansion of our knowledge.

I wonder why these folk thought it necessary to write their speculative viewpoint in the first place?

Brian Souter

So you do that often then?

Because many if not all of the folks know what they’re talking about.

Turns out a glider can be operated in IMC:

"IFR flight by a glider will normally require

the designation of an area of operation rather than a route since

the mode of flight will normally include low speed, circling flight,

drifting cross-country at about the same speed as the wind aloft and

an inability to maintain a preselected altitude or ground-directed

heading. The dimensions of the area and altitudes shall be determined

by mutual agreement between the operator and facility. The capability

of the pilot to communicate with the Center should be considered in

approving the flight."

I see no exception to the sue of a VFR only glider in IMC however.

It also appears that they are allowed in airspace Alpha with some equipment requirements although I don’t think the pilot needs an instrument rating.

Odd and interesting.

As an instrument pilot I’d oppose allowing a non rated aircraft, powered or not, with a VFR pilot in IMC with me.

Situation could have encompassed severe icing; followed by autopilot chasing the parameters resulting in an overstressing of the airframe components.

I agree, and thought these flights had two pilots.

I was surprised to read this was single pilot night IFR in ice… and a medevac flight. Why? Even if it was one of the time builder instructors in the copilot seat… it sounds better to me.

I recall years back a number of episodes in which Piper Malibu aircraft experienced in-flight break ups. I think to the point that the flight operations of the aircraft were severely restricted until the problem was worked out. I also recall that after investigation the likely problem was use of the autopilot in vertical speed climb mode (rather than airspeed mode) without proper monitoring. The airplane would pitch back trying to keep the VS until stall, then an abrupt maneuver to recover would break the airframe. Enhanced pilot training was the final fix, no changes to the aircraft. Is my memory correct, and could that be a factor here? I can’t take the discussion any further because I’m not familiar with PC-12 or it’s autopilot.
It’s a tragedy; we have to draw some knowledge from the event if we can.
