FLYING LESSONS WEEKLY

FLYING LESSONS for December 28, 2023

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:

Sometimes in the process of analyzing accident reports to glean LESSONS we can apply to make our own flying safer, it’s easy to forget the horrible tragedy that unfolded and the consequences of that tragedy on those aboard, their family, friends and others who depend upon them. I usually manage to avoid criticism for being too objective, and try my best to respectfully acknowledge the human cost while applying what we know to what could happen under similar (or even different) circumstances. 

No one called me out, or even mentioned it to me in any way, when I included this item condensed from an FAA preliminary accident report in last week’s Beech Weekly Accident Update:

A possible first thought if I was to develop LESSONS from this preliminary information would be a discussion of establishing and maintaining a climb attitude after takeoff, perhaps in reduced visibility conditions or when departing a short runway…things not necessarily the case in this event, but which are at least suggested by the circumstances of the initial report. Something told me, however, that this might have also been a partial or total power loss following takeoff, or that collision with power lines was a result of something else. I didn’t know, so I simply added that report to the tally I keep on piston Beechcraft mishap statistics.       

A few days later I saw this posted on social media:

A loss of engine power including an inflight fire suggests an exhaust system or turbocharger leak that creates a 1300°F/700°C blowtorch in the engine compartment in close proximity to fuel and oil lines. In one case several years ago such a leak burned all the way through the firewall of a Beech Baron, cutting through the forward wing spar with disastrous effect. It can happen fast, with little the pilot can do in response. It’s a great reminder of the positive impact of Airworthiness Directives, which warn turbocharged airplane pilots to watch engine exhaust clamps closely and requires they be proactively replaced on a 400- to 500-operating hour schedule depending on the engine type. Even then, there’s a chance a clamp might fail sooner, or some other crack mechanism occur, that is hard to detect.  

There are a lot of accident commentators out there. Many are very quick to judge the pilot based on meager information of just-released preliminary and local media reports. Some others—the late Richard McSpadden’s Early Analysis series, Scott Purdue’s FlyWire videos, Max Trescott’s Aviation News Talk reports among them—try to be as respectful as possible while drawing positive, actionable information from the data. I hope I’m always as successful at maintaining this respect and objectivity.

I try to end each year of FLYING LESSONS on a high note. Seeing the B36TC pilot’s online comment this week changed that somewhat, but I think we can still be positive. LESSONS for the coming year should include:

  • Airworthiness Directives (ADs) and other maintenance and inspection requirements are not a bad thing. Sometimes the requirements might not seem to be supported by data, but especially in recent years most ADs must pass stringent rules of evidence before regulators even consider adding a maintenance requirement. Be diligent about AD compliance. Don’t be too quick to oppose new proposals, but include hard data in your comments to regulators if you feel they modify or refute a proposed rule. In my real job at the American Bonanza Society I’ve taken hard data to FAA asking for a necessary inspection requirement that was subsequently adopted, used manufacturer and other objective information to remove some affected models from an existing AD whose design made the AD meaningless for the type, and caused the FAA—again, with data—to withdraw a proposed AD and replace it instead with a recommendation and not a requirement. With data you can be heard. The result is worth listen to (and acting upon) for your personal safety and that of your passengers, not just because it’s required.
  • If a commentator jumps to personal judgement on the basis of preliminary information, honestly evaluate if it’s done to prevent future accidents or if it’s just for shock value to increase the number of hits and make the commentator appear more magnificent. Consider the possible motivations before accepting advice or opinion—mine included.
  • Never forget the human tragedy behind accident reports. Regulators, investigators and pundits focus on fatal crashes. But surviving “serious” injuries is almost always a major, life-changing physical and emotional event involving real people and all those around them. Even if it turns out the pilot did—or did not—do some identifiable thing that caused or could have prevented an accident, learn the LESSONS and leave judgement to others.

Has what you’ve learned in FLYING LESSONS this year been worth it to you? How many hours of “dual” have you received from the weekly reports? If you’ve learned at least as much as you do in an hour of flight instruction, please consider donating the amount you’d pay your flight instructor for just one hour of her/his time. The proceeds will help cover my out-of-pocket expenses for hosting and delivering FLYING LESSONS Weekly. If that’s more than you feel it’s worth, even $5 helps cover my out-of-pocket costs.

I only make this appeal two weeks each year. Please consider donating what you’d pay for just one hour of flight instruction, to help me cover the costs of hosting, delivering and improving FLYING LESSONS Weekly. Thank you to all who have contributed through the year, and all who will help now.

Debrief: 

Readers write about recent FLYING LESSONS:

Reader/instructor Paul Sergeant writes about engine failure technique, which is a very aircraft type-specific thing: 

Me too, many years ago. Check out this video you might use with your students. Thanks, Paul. 

Mike Radomsky, one of the founders of the Cirrus Owners and Pilots Association and owner of a Cirrus-based simulator training program in Las Vegas, Nevada, writes about last week’s LESSONS on flying in the fourth dimension:

As a once-astrophysics major (I went to college to take up space) who drifted into other areas I love a good science tie-in. Thanks for relating a good way to think about four-dimensional flight, Mike. 

Reader and business aviation consultant Jim Lara adds:

Thank you very much, Jim. And thanks for providing another good example from which to learn.

Accident investigator, instructor and past Naval Aviator Jeff Edwards continues:

As I wrote last week, I’m at least as concerned about the destabilizing effect of gear extension late in an engine-out glide as I am the irregular loading that results from landing gear shearing off during impact. Interesting stats from your Cirrus review. 85% of descents under CAPS parachute had no or only minor injuries. 85% of those in which the parachute was not used had no or only minor injuries. If I had a parachute I’d use it when the situation requires. For the vast majority of us who do not have that option, nearly identical results occurred as long as the pilot maintains control to touch down wings level, under control at the slowest safe speed. Thanks, Jeff!

Reader John Miller asks (for a friend):

I don’t know about sailplanes (perhaps they have enough cavities they scoop themselves full of water when ditched?). I do know one the worst things you can do in an amphibious airplane is to land in water with the wheels down (far worse than the converse). That may be, however, because as soon as the airplane pitches forward when the wheels drag against water the nose of the floats dig into the water and flip the airplane over. Experts, what do you say? 

Reader Jim Preston takes us back to the tragic event that started much of this train of thought:

Someone earlier (I forget who, sorry) noted the C177RG’s unusual nose gear door that works a little like the speed brake on a tactical fighter jet. This would make gear extension even draggier in the Cardinal RG than most other types, and even more of an impediment in an engine-out glide.

Yes, I eagerly await more information about the Richard McSpadden/Russ Francis crash to fine-tune Richard’s final LESSONS to us all. What we know so far is that (from the NTSB preliminary report):

A C177RG trying to catch up with a preceding A36 Bonanza most likely had its gear up before the point it turned back toward the airport with a reported problem. However, you’re correct, Jim, in that the added drag of retracting landing gear can make matters worse too, if the gear is down in a glide and the pilot decides at the last minute he/she is not going to make it. All the more reason to use gear-up as the default technique in an engine-out glide in retractable gear airplanes, unless you find yourself close in and high on the approach to a runway or other prepared surface you could reasonably take off from normally (such as a highway). Thank you. 

Reader/instructor/investigator and commentator Scott “Gunny” Perdue wraps it up for this week:

I posed those same questions about pilot and passenger restraints in the November 30 FLYING LESSONS. Thanks, Scott.
