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:

The tragic crash of a twin Cessna turboprop cost six lives. From the NTSB preliminary report:

 

Local television news posted on its website about the crash, saying:

On the face of it that news report is suspect, because the Cessna 441 Conquest does not require a second pilot. It’s possible the operator chose to have a second pilot aboard for safety or redundancy, but it’s not clear the right-seat occupant—although a certificated pilot—was acting in any capacity other than passenger.  

The report raises a question, however: what responsibility does the pilot-in-command have for passengers who are under the influence of alcohol or chemical substances? For U.S. readers the answer comes from 14 CFR 91.17. Outside FAA jurisdiction, check your general operating rules for the use of drugs and alcohol to find if there are similar rules for you.

91.17b tells us:

Except in an emergency, no pilot of a civil aircraft may allow a person who appears to be intoxicated or who demonstrates by manner or physical indications that the individual is under the influence of drugs (except a medical patient under proper care) to be carried in that aircraft.

Another question: “Why? Other parts of 91.17 prohibit operating an aircraft or serving as pilot-in-command under the influence or within a time limit after using certain medications or intoxicating substances…so the pilot must protect him- or herself. The reality is that the Federal Air Regulations give pilots a great deal of freedom to operate as long as no one else is endangered. It’s when passengers and persons on the ground are at risk that many regulatory restrictions come into play. I suspect the restriction against drunk or drugged passengers stems from the hazard they present to themselves, and the potential risks to other passengers and persons on the ground if that passenger should interfere in the safe operation of the aircraft. 

Regardless of “why,” one of the many ancillary responsibilities of the pilot-in-command is to detect the symptoms of substance abuse among passengers before flight, and to prevent “influenced” persons from boarding the aircraft. In that regard, the TV news report was not wrong to report the right-seat occupant’s condition.

Debrief

Readers write about recent LESSONS:

Several readers responded to last week’s “The Myth of Utility.” Let’s begin with this from John Majane:

John, I see you on Facebook posting about flying your Bonanza almost every week, sometimes multiple times. Few people seem to enjoy flying their airplane more than you. Thanks for writing…and for reading FLYING LESSONS.

A reader and student pilot who chooses to be anonymous addresses the question that prompted last week’s LESSONS:

That may be a better answer than mine! Thank you, Anonymous.

Reader Sarah Staudt adds:

Congratulations on standing your ground in the name of safety and performance, Sarah. Thanks for addling your insights.

Reader Brad Wolansky, whose question about loading his Piper Seneca began this discussion, sent me this follow-up:

Thanks for the update, Brad, and thank you for prompting these LESSONS.

Here are a few additional, short notes from readers: 

I was once described by my supervisor to prospective new hires as “the one who tells you to eat your spinach.” Thank you Roy, Mike and Jeff. 

Reader David Horvath addresses a Debrief item in last week’s report:

I also make a big show of waving the keys to a marshaller as soon as I shut down and before he/she approaches the airplane. I wonder how many FBOs train their linepeople to know the significance of that motion. Good reminder, David, thank you.

Our very insightful anonymous student pilot also wrote:

Excellent idea, and great catch! The high-level people at FAA who can make this happen are reading this report. Do you need me to submit a formal request, or can you take it from here? Thanks again, Anonymous.
