US-3.5 requires at least one accident-derived scenario built into a teachable lesson.
Use the base-to-final overshoot. A pilot overshoots the extended centerline turning final, increases the bank, feels the bank steepen and adds opposite aileron while holding the nose up with elevator and adding bottom rudder to tighten the turn, and enters an uncoordinated stall at an altitude from which recovery is not available.
This is the correct choice for three reasons. It is a category rather than an anecdote, so it does not depend on one report. It is the accident a new instructor is most likely to be sitting in. And AC 61-67C with Changes 1 and 2, Stall and Spin Awareness Training, read 2026-08-13, exists specifically to address this training area, which gives the scenario a citable source rather than a war story.
How to teach it, which is the actual content of the element. Do not narrate the accident. Give the candidate the setup and have them build it into a teachable lesson: what the student is asked to notice, at what point the instructor intervenes, what the completion standard is, and what makes the lesson safe to run. Then have them teach a piece of it.
The link forward. This scenario is revisited in lesson 31, the spin ground lesson, and in lesson 33, the cross-controlled stall. Tell the candidate that. Emergency and risk content appearing in more than one phase is US-5.6's requirement, and this lesson is where the thread starts.
~~Open item.~~ Closed 2026-08-14. US-3.5 asks for consistency with "the existing decision-tree training material in this folder." The material was located, the NTSB final report was read in full to settle the facts it rests on, and Erick decided how it is used: the base-to-final overshoot stays as element 9, and the decision trees are used at element 10.
Why the overshoot stays at element 9. The three reasons above still hold and none of them was about availability. It is a category rather than an anecdote, it is the accident this candidate is most likely to be sitting in, and AC 61-67C addresses it directly. Swapping in a single case would have traded a category for a story, which is a worse element 9 even though the story is now fully sourced.
Why the trees belong at element 10. Element 10 asks the candidate to run a scenario-based training block in which a Simulated Student makes decisions. The preflight tree is already exactly that: nine steps from self-evaluation to the go decision, each with a thorough, a partial and a skipped branch. It replaces an improvised scenario rather than adding to the lesson, so no hours change, and every candidate now meets the same decisions instead of whatever the instructor invented that morning.
The apparent contradiction that held this up was not one. The trees say 400 feet AGL and the spin material says 500 feet AGL. Both figures are in the NTSB report and they describe different moments: the sharp left turn began at about 400 feet AGL on GPS data, and two witnesses saw the rapid left roll begin at about 500 feet above the departure end of the runway. The gap between those two numbers is the entire margin the pilot had, and saying so is better teaching than either figure alone.
The one rule for this element. sources/NTSB-WPR11FA316.md is the only permitted source for any fact you state about that accident, and it is the record every North Aero document that touches this accident is being brought onto. The trees are a decision-branching instrument, not a source of facts. Their scenario framing puts the planned departure at 1800 where the accident was at 1928, which is harmless as a planning exercise and wrong as a statement about the flight. If a candidate asks what actually happened, answer from the fact sheet.
