Paperwork Triage: Three Passengers, a Lapsed Medical, and an Overdue 100-Hour
Dale, a 54-year-old private pilot, wants to take two neighbors and their teenage son on a Saturday morning pancake-breakfast flight 45 minutes away in the club's Cessna 172S. He asks the club's ground instructor to "check his paperwork." The facts: he last flew 13 months ago, and his last flight review was 25 months ago. His last three takeoffs and landings were 5 months ago, all in daylight. His third-class medical was issued three years ago and he has never taken a BasicMed course. The airplane's annual inspection was signed off 11 months and 20 days ago. Its 100-hour inspection was completed 106 hours ago, and the club uses the airplane for flight instruction and rentals. The transponder was last tested 25 months ago. The pitot-static system and altimeter were last checked 26 months ago. The flight will stay in Class E airspace below 10,000 ft and never enter Class B or C. Saturday's forecast is clear and calm.
1. Sort these items into three groups: items that ground the flight no matter what, items that would matter only in other airspace or conditions, and items that are fine. Explain each placement.

Grounds the flight regardless of route or weather:
- Medical. A third-class certificate issued three years ago is expired for any private pilot operation, and he has no BasicMed. Without a medical path he cannot act as PIC at all.
- Flight review (61.56). Twenty-five months exceeds the 24-month window. He is not eligible to act as PIC, with or without passengers.
- Passenger currency (61.57). Three takeoffs and landings within the preceding 90 days are required before carrying passengers; his are 5 months old. Note this is a separate requirement from the flight review - fixing one does not fix the other.
- 100-hour inspection (91.409). The airplane is 6 hours past due and is used for instruction and rental, which is exactly the operation the rule covers. The airplane is unairworthy for this flight until inspected.
Matters only elsewhere:
- Transponder test (91.413). Required within the preceding 24 calendar months for operation in Class A, B, or C airspace, above 10,000 ft MSL, and within the Mode C veil. A Class E flight below 10,000 ft outside those areas does not require it.
- Pitot-static and altimeter check (91.411). A 24-calendar-month requirement tied to instrument flight rules operations. A day VFR flight does not need it.
Fine: the annual inspection (11 months 20 days) is within the 12-calendar-month window, and the weather is not a factor.
2. Dale says, "So I just need a flight review and I'm set for Saturday." Correct him, and explain how you would sequence what he actually needs.

He is treating four independent clocks as one.
Sequence:
- Medical first. Nothing else matters until he has a valid medical certificate or completes BasicMed. That is the long pole and it should start today.
- Flight review. One hour of ground and one hour of flight with a flight instructor, after the medical is in hand. Twenty-five months away from flying also argues for more than the minimum hour before he carries passengers.
- Passenger currency. Three takeoffs and landings within 90 days. The flight review's flight portion will likely cover this, but he should confirm the landings are logged and dated.
- The airplane. The 100-hour inspection has to be completed before the club can rent it for this flight, and that is the club's scheduling problem, not his.
The concept to teach. Currency is a set of legal minimums that expire on schedules; proficiency is a skill that decays on its own timetable. Thirteen months of no flying plus a 25-month gap since any review means he will be legal long before he is ready to fly two neighbors and a teenager. Suggest a solo or dual warm-up flight first and a gentler first passenger trip than a 45-minute cross-country.
3. The club mechanic says the transponder and pitot-static checks are "basically due" and offers to do them while the airplane is in for the 100-hour. Is that the right call, and what does the answer teach about airworthiness?
Read the worked answer
Legally, neither check is required for Saturday's flight. Both rules are conditional: the transponder test applies to airspace and altitudes this flight will not use, and the pitot-static check applies to IFR operations. An airplane can be perfectly airworthy for a day VFR flight in Class E with both of those inspections overdue.
Practically, doing them now is the better call. Two reasons. First, the airplane is already opened up for the 100-hour, so the marginal cost and downtime are low. Second, the moment the club's next renter files IFR or asks for a Class C transition, the airplane is grounded again - and someone will discover it at the worst possible time, on a Saturday morning with the airplane fueled and the renter's family in the lobby.
The teaching point. Airworthiness is not one global property; it is specific to the operation. The same airplane can be legal for a VFR hop and illegal for the flight the renter actually planned. The instructor's job is to teach renters to ask "airworthy for what?" before they accept an airplane, rather than assuming that a current annual means the aircraft is good for anything they can think of.
