The regulation asks for a review of the Part 91 operating and flight rules, which sounds dry until you make it about the flying you actually do. I would rather spend the hour on the rules that touch your trips than march through the whole of Part 91 front to back.
So we talk about what has changed since your last review, and we go over the local airspace properly - the Luke SATR and the Phoenix Bravo catch people out constantly, especially if you have been away from the valley for a while. We will also go through your logbook and the aircraft documents together, partly because it is worth knowing everything is current, and partly because it is a good excuse to find out what you have been flying.
The maneuvers are at my discretion, which really means they are built around you. Typically takeoffs and landings, slow flight and stalls, steep turns, a few emergency procedures, and a simulated diversion - but if you tell me the crosswind landings have gone rusty, that is where the hour goes.
This is not a checkride. There is no pass or fail and nothing goes on your record if a landing is ugly. I am looking for whether you are safe and current, and if something needs more work we just keep flying until it is there. Then you get the endorsement.
A completed WINGS phase, or a new certificate or rating earned in the last 24 calendar months, counts instead - if either applies to you, you may not need this at all. And if you have a friend who has been out of the airplane a while, bring them along for the ground hour.
