The Cory Lidle Tragedy

Whenever there's a high-profile airplane crash, dozens of concerned friends and family members call to tell me that small planes are proven death traps. The aviation community grieves the loss of Cory Lidle, as does his family and baseball fans everywhere. But here's one pilot's view.

First, let's back off the hysteria. No mode of transportation is completely safe. My guess is that at least a dozen cars a month run into buildings somewhere in America; people panic and hit the gas instead of the brake, they're going too fast for the conditions, they're distracted, etc. The same kinds of things can happen to pilots too.

Lidle was a relatively inexperienced pilot. New automobile drivers are involved in a disproportionate number of accidents; so are new pilots. He was flying a fine but rather sophisticated plane, the Cirrus SR22. There's a saying among pilots: "A fool and his money are soon flying more airplane than he can handle." It's too soon to know if that applies to Lidle, but it was a factor in the John F. Kennedy Jr. crash a few years back.

Lidle was engaged in low-altitude maneuvering flight, which is the most dangerous phase of flight. It demands special attention to detail. It sounds like he was doing some sightseeing, which by definition is distracting. When you're flying low and slow and get distracted, things can go south pretty quickly. From the early reports, Lidle was banking when the accident happened. At high bank angles, the airspeed at which the wings lose lift increases. If you're not paying attention, you can easily fall below critical airspeed. When that happens in a steep bank, a spin is likely. The SR22 has great spin-recovery characteristics, but it often takes 1,000 feet of altitude (and no tall buildings in the way) to pull out of one. Is that what happened to Lidle? It's way too early to tell, but that's where my best guess is for now.

Before his death, Lidle assured his family and friends that flying was perfectly safe. Obviously, he was as wrong. But so would be anyone who says that driving a car is perfectly safe. Like drivers however, there is much that pilots can do maximize their safety factor, like knowing their personal limitations and staying within them, allowing for a generous margin of error in all phases of flight, avoiding high-workload or distracting situations, etc.

Cory Lidle's death: a tragic accident. Given the right conditions, it could happen to any pilot. Just like a tragic car accident could happen to any driver. Will it make me a more careful pilot? Absolutely. Will it keep me from flying? Absolutely not.

Good points, Mark.

I thought the Cirrus had a spin chute system? I'll be interested to hear what NTSB/FAA figures out about what happened and why the chute system wasn't deployed.

Also, wasn't he flying with his IP? Seems like a competant IP would've taken control if he recognized the SP was getting into trouble.

Sad, indeed. He had a wife and a 6yo kid...

Just like me.

Jim - The Cirrus has a chute. I too am puzzled with why it wasn't deployed. There may not have been enough time to recognize the need for the chute then deploy it, or they may not have had enough altitude for it to be effective.

Re: the instructor. I haven't heard definitively that there was an instructor on board. You may recall that early news reports of the JFK Jr. crash said that an instructor was on the plane. False. And the two yo-yos who violated the Washington security zone a couple of years ago--early reports said that it was a student pilot and his instructor. Also turned out to be false.

However, assuming there was an instructor on board, several scenarios are possible. The co-owner of my plane is an instructor and we fly a lot together. But when I'm pilot in command, he's not in "instrcutor mode," watching my every move and poised to take control at the first hint of trouble. That may have been the case with Lidle. Or the instructor may have become distracted also.
