Legal Interpretations

As students of aviation, we are familiar with our regulations, the AIM, Advisory Circulars and other instructional, regulatory and best practice FAA guidance publications. But questions remain about whats legal. One sure, but unpleasant way to answer them is to attract the FAAs enforcement apparatus. This begins with your friendly neighborhood Aviation Safety Inspector, and can lead to suspension or revocation orders, plea bargaining, trials and appeals with the NTSB, and ultimately, the federal courts. There is a better way.

Key Takeaways:

The FAA Chief Counsel's letters of interpretation serve as a vital resource for pilots to understand and comply with complex aviation regulations, offering clarity beyond official guidance.
These interpretations, now publicly accessible on faa.gov, cover a broad range of subjects including equipment requirements, IFR procedures, and pilot training and currency rules.
Specific interpretations clarify rules on items like anti-collision light systems, required cockpit clocks, mandatory procedure turns, maximum holding leg lengths, IFR operations in uncontrolled airspace, and strict adherence to lost communication procedures.
While valuable for legal clarity, some interpretations may challenge common aviation practices or yield counter-intuitive results, occasionally making previously accepted procedures legally problematic.

But questions remain about what’s legal. One sure, but unpleasant way to answer them is to attract the FAA’s enforcement apparatus. This begins with your friendly neighborhood Aviation Safety Inspector, and can lead to suspension or revocation orders, “plea bargaining,” trials and appeals with the NTSB, and ultimately, the federal courts. There is a better way.

The FAA Chief Counsel Office has been issuing letters of interpretation in response to inquiries for decades. Once only available from legal research and aviation compliance companies, the FAA now publishes them. At www.faa.gov, search for “Legal Interpretations & Chief Counsel Opinions.” They cover a wide variety of subjects including logging flight time, whether manufacturer Service Bulletins are mandatory, airline and charter pilot duty time limitations, and the multiple and often-grey areas where Part 91 and Part 135 charter operations collide.
