FLYING LESSONS uses recent mishap reports to consider what might have contributed to accidents, so you can make better decisions if you face similar circumstances.  In most cases design characteristics of a specific airplane have little direct bearing on the possible causes of aircraft accidents—but knowing how your airplane’s systems respond can make the difference in your success as the scenario unfolds. So apply these FLYING LESSONS to the specific airplane you fly.  Verify all technical information before applying it to your aircraft or operation, with manufacturers’ data and recommendations taking precedence.  You are pilot in command and are ultimately responsible for the decisions you make.

This week’s LESSONS

Six died when a sightseeing helicopter carrying a family of five broke up in flight and plunged into the Hudson River. There’s discussion of mast bumping and NTSB is investigating the inflight separation of the engine transmission and main rotor system. Here’s a YouTube video that reviews the facts as they were known at the time the video was recorded, shortly after the crash. The video creator doesn’t try to infer too much from the limited information available—although he does speculate briefly about causes—but he explains what the radio calls mean for someone not familiar with ATC procedures or the aviation safety record. The value of this particular video, in my view, is that includes the ATC audio.

No doubt there is much to be discovered during the investigation, and LESSONS to learn once the investigation is done.    

All three aboard a Cessna 310R were killed when it crashed onto a road in Boca Raton, Florida. The aircraft was totally destroyed. The Aviation Safety Network (ASN) reports

The Cessna twin’s flight track –eight left-hand circles, all at 500 feet above ground level or less—suggests a wild ride: radio calls from the pilot report a stuck rudder and video showing a jammed, fully deflected rudder. One unverified report is that: 

A YouTube video traces the video with commentary. There’ll undoubtedly be LESSONS from the facts that emerge here as well.

A family of six aboard an MU-2 perished when, according to the ASN:

Weather may have been a factor, with low clouds and icing conditions near the surface reported at the time of the crash. The Flightaware track and altitude log shows a quick climb to 16,000 feet then a descent for the approach…possibly a low, visual approach or a circling approach before altitude went down as speed went up…until impact. 

More details are available in this YouTube video, which focuses on the publicly available factual evidence. Here, too, are LESSONS waiting to be learned.

I was struggling with what to write in this week’s LESSONS, with all these fatalities in so short a time…plus two in a Cessna T210 in Louisiana, the solo pilot of a Cassutt III in Oklahoma, an Aeronca Champ pilot in Missouri (whose passenger suffered “serious” injuries), the Texas pilot of a Saberwing, and two aboard a Mooney in Tennessee—eight fatal accidents and 22 dead in the last two weeks. 

The most recent AOPA ASI Richard McSpadden Report reveals 162 fatal general aviation crashes in all of 2024 (preliminary data, but that number shouldn’t change). I know the last two weeks have been an anomaly. But if it were indicative of a consistent trend there would be 208 fatal accidents in 2025…28% more than the 2024 rate. 

Fatal accidents of all sorts, including airlines, have been widely reported this year. Preliminary 2025 data suggest the total number of aircraft accidents this year is actually lower than last. But is the number of fatal accidents trending upward?

So with all this tragedy, what do I write? What LESSONS can we learn? Suddenly I had the opportunity to choose a different accident as our focus this week:

The pilot and his passenger were taking off in an A36 Bonanza. Here are the initial facts from the FAA preliminary report:

The FAA notes that the pilot was unhurt and the passenger suffered “minor” injuries. Airplane damage, according to the FAA’s initial report, is “minor.”

Here’s what the Aviation Safety Network reports:

While I stewed over what to write this week I received a phone call that changed the direction of this edition of Mastery of Flight™. A FLYING LESSONS reader called to thank the organization for which I work, the American Bonanza Society, and me personally (Mastery Flight Training, Inc., being my personal, after-hours craft), for helping save his wife’s life, and his. He was the pilot of that A36, and described his experience (paraphrased from my notes taken during the call):

A turbonormalizer is a conventional turbocharger rigged so it develops sea level manifold pressure to a high altitude. The “normal” in turbonormalization is about 30 inches of manifold pressure at full throttle, what is standard at sea level in non-turbocharged engines (conventional turbocharging boosts pressure the higher than is natural at sea level). Like many turbocharging systems, turbonormalizer output is automatically controlled by a wastegate system that itself is controlled by oil pressure—more oil pressure creates more manifold pressure and vice versa. When oil is cool the oil pressure is higher than normal, so it’s not unusual for a little extra manifold pressure on the first takeoff of the day until engine heat raises the oil temperature. Ten percent extra manifold pressure as reported by the caller is a bit much, but again, it’s not outside of expectations in this type of modification under these conditions. 

The reader continued (again, paraphrased from my notes):

The reader said he has a friend who is a former Naval aviator and who “flies Falcon jets around the world” with whom he flies “every month or so” to practice approaches and other things to keep his skills sharp. He credits this, along with the training he has taken and the reading he continues to do as part of his habit of “continual training” that made him ready when he and his wife needed him to be.    

There’s evidence to support that best results come from keeping the landing gear up for off-airport landings—it allows a smoother slide-on without the hazard of being slammed forward if the nose gear collapses, or in a worst case, the airplane cartwheeling. Gear up is my standard procedure for an off-airport landing. 

But you can’t argue with success: a catastrophic engine failure close to the ground in which the pilot maintains control all the way to touchdown on what may have been the best surface available, and the worst that happens is bruising from seat belts and shoulder harnesses. Well done, reader.  

I will likely focus on one or more of the three tragedies above (not to dismiss the others) once more information is publicly available. But despite their severity, at least in some cases success is possible. I’m glad we had the opportunity to learn from success this week—accidents are far better documented and survivor stories are hard to find. It’s a great reminder that, as written by the 7th century BCE lyric poet (an early term for historian) Archilochus:

Readers, be ready for your personal success story with a habit of continual training.

Thank you, reader, for your call, for crediting my work (day and night) as part of your successful life-saving response, for reinforcing that success is possible, and for making this week’s LESSONS easy to write.
