Last Sunday afternoon, nine people died when a Learjet rocketed into the ground of a suburban neighborhood of Palm Beach County, Florida.
And I mean rocketed. Chances are you’ve seen the dashcam footage. The most chilling part, to me, is the missile-like acoustics — the Doppler shriek of the engines as the plane flashes briefly into view before disintegrating into oblivion. Its speed when it hit the ground has been estimated at around six-hundred miles per hour.
A freeze-frame image shows both of the Learjet’s horizontal stabilizers missing. Those are the small wings in the back, the rear-hinged portions of which are called elevators, that provide a plane’s pitch control — its nose-up or nose down orientation. Without them, the plane is going in one direction only: down.
Reportedly, the stabilizers and other parts of the tail were found nearly four miles from the crash site. One question is whether they detached before or during that horrendous nosedive. Did their detachment cause the dive, or did the dive tear them away?
My money says the latter. I’m leaning towards a theory that the pilots found themselves within (or very close to) a thunderstorm, battling heavy turbulence and ice accretion. The plane ended up in an aerodynamic stall from which the crew failed to — or could not — recover. It then began to plummet at a speed and attitude beyond its design envelope. The stabilizers and other parts were subsequently ripped off, making the plummet even more extreme.
Inflight icing can, if unchecked, lead to a loss of lift and potentially a full-on stall. Smaller planes are more susceptible to this than commercial airliners. A Learjet is comparatively small, but like any sophisticated aircraft it has deicing equipment built into its wings, engine inlets, air data probes and so forth. It’s possible, however, that unusually severe icing, perhaps combined with strong turbulence, caught the pilots off guard. A failure or malfunction of the deicing system is also in play.
The stall recovery technique would be basic: lower the nose, level the wings, add power. And be careful to avoid a secondary stall by easing the nose up too soon. Easier said than done. A stall in a jet isn’t like a stall in a Cessna; it can take thousands of feet to recover, and Learjets are known to be particularly stall-unfriendly. Add ice to the mix and you’ve got a highly dangerous situation. Icing changes the contours of the wings and can make the characteristics of a stall more violent and unpredictable.
Which brings us to the next question: how did they get themselves into such weather in the first place? If there’s one thing pilots avoid at all costs, it’s thunderstorms. Were they trying to fly safely above the weather — a tactic fraught with risks? Were the radar returns deceptively docile-looking? Or did they simply underestimate, or misinterpret, what they were dealing with?
The less likely scenario has the stabilizers coming off before the high-speed plunge, effectively causing it. If so, similar questions arise. Did they detach from extreme turbulence? Did the pilots overreact to a turbulence encounter and cause a structural failure? Did icing contribute?
People also have been bringing up the possibility of a dangerous phenomenon known as “Mach tuck.” This is a sort of high-speed, high-altitude stall that results when the air flowing around the wings exceeds a critical velocity. Shock waves form on the wings and migrate backwards, shifting the wing’s center of lift to a point behind its normal position, causing the nose to pitch down abruptly. This would never happen in normal, stable flight, but in the throes of a storm, who knows. Learjets are, let’s just say, sensitive, and there’s not a lot of aerodynamic wiggle room at high altitudes. Worse yet, icing can exacerbate the effects of Mach tuck.
One way or the other, the plane probably shouldn’t have been where it was. How and why it got there is the biggest question of all.
The copilot was only twenty years-old — a very young age to be at the controls of a private jet. The captain was 55 and presumably more seasoned. Records show him obtaining his ATP license (the certificate required for his position) about five years ago. We don’t know if their backgrounds or experience levels were a factor, though surely it’ll be looked at.
