Does a flying club aircraft need a 100-hour inspection?
October 20, 2026 · Chris van Eijk
Whether a flying club aircraft needs a 100-hour inspection depends on which rulebook it flies under. Under the FAA rule it depends on the flight, not on who owns the aircraft. Under EASA it depends on the aircraft's maintenance programme. This guide sets out both, quoting 14 CFR 91.409, three FAA Chief Counsel interpretations of it and EASA Part-ML, all read on 20 October 2026. It also covers when the next one falls due after an inspection that came early or late. That is where the two rulebooks count differently.
Short answer: In the United States, a club aircraft needs a 100-hour inspection (or an annual) within the preceding 100 hours of time in service only when it carries a passenger for hire, or when it is used for paid flight instruction by someone who also provides the aircraft. A member who rents the club aircraft and flies it alone does not trigger the rule. A member who hires an instructor independently usually does not either, but the FAA may check whether the club, or an instructor acting for it, effectively provided the aircraft. A club that supplies both the aircraft and the instructor for paid training does, even if the instructor's cost is folded into the rental or the dues. In Europe, a light aeroplane on EASA's minimum inspection programme is inspected "every annual or 100-h interval, whichever comes first", whatever the flight is for.
Does this flight need a 100-hour inspection?
FAA (14 CFR 91.409(b)): depends on the flight
- No
A member rents the club aircraft and flies it themselves
Rental without a pilot provided is not carriage for hire or instruction for hire; the annual still applies.
- Usually no
A member flies with an instructor they hire themselves
The rule does not apply when the person receiving instruction provides the aircraft — but the FAA may check that the club or the instructor did not effectively provide it.
- Yes
The club provides both the aircraft and the instructor for paid training
Writing about a flight school, the FAA said that adding the instructor to the rental or the membership fees does not avoid it, and neither does an instructor who is not a regular employee.
- Yes
Anyone carries a passenger for hire in the aircraft
91.409(b) covers every aircraft carrying a person other than a crewmember for hire.
EASA (Part-ML, ML.A.302(d)): depends on the programme
- Minimum inspection programme: every annual or 100-h interval, whichever comes first, for every flight — club, private or training.
- Programme based on the manufacturer's instructions: the intervals in those instructions.
- Commercial ATO or DTO: airworthiness managed by an approved CAMO or CAO, maintenance by an approved organisation.
What the FAA rule says
The rule is 14 CFR 91.409(b): "no person may operate an aircraft carrying any person (other than a crewmember) for hire, and no person may give flight instruction for hire in an aircraft which that person provides, unless within the preceding 100 hours of time in service the aircraft has received an annual or 100-hour inspection". Two kinds of flying trigger it: carrying someone for hire, and instruction for hire in an aircraft the instructor provides. Everything else falls under the annual alone. Under 91.409(a), no aircraft may be flown without an annual inspection "within the preceding 12 calendar months".
The exceptions sit in 91.409(c). An aircraft with a special flight permit, a current experimental airworthiness certificate, a special airworthiness certificate in the light-sport category or a provisional airworthiness certificate is outside both paragraphs. So is an aircraft on an approved part 125 or 135 inspection programme, and one on a progressive inspection under 91.409(d) or an inspection programme under 91.409(e).
The four flights a club actually flies
The FAA's Office of the Chief Counsel has answered the club question several times, and the letters agree on one principle. In the words of its 2015 letter to the flight school Fly By Knight, "the 100-hour maintenance inspection requirement depends on how the aircraft is operated during the flight in question."
- A member rents the aircraft and flies it. No 100-hour. The 2015 letter: if the operator rents the aircraft "to a customer, however, and does not provide the pilot, that aircraft need not have an annual or 100-hour maintenance inspection within the preceding 100 hours of time in service."
- A member flies with an instructor they hire. Usually no 100-hour. The FAA's 2016 letter to Nicholas Pipitone, written about club aircraft: "The 100-hour inspection requirement does not apply if the person receiving flight instruction provides the aircraft." The same letter adds a warning. When the student does not own the aircraft, the FAA "may review the manner by which that person provided the aircraft to ensure the instructor, or an entity represented by the instructor, did not effectively provide the aircraft." A footnote adds that the FAA interprets providing the flight instructor "very broadly". A member who owns or leases the aircraft provides it; a member who books the club's aircraft is the case the FAA may look at.
- The club provides both the aircraft and the instructor. 100-hour required. In a letter to Blue Line Aviation, answering a 2017 request, the FAA wrote that "A flight school cannot avoid the 100-hour inspection requirement by not charging separately or explicitly for the instructor (e.g. adding the cost of the instructor to the overall rental fee for the aircraft or to membership fees)". It applies "even if the instructor is not a regular employee of the school". The letter names three conditions: the school provides the aircraft and the instructor, it receives compensation, and flight training is given. A checkout in which no training is given is not instruction. The letter is about a flight school; we read it as applying equally to a club that arranges and pays its own instructors.
- Anyone carries a passenger for hire. 100-hour required, straight from the text of 91.409(b).
Ownership does not settle it either way. Pipitone had asked whether a leased aircraft counts as "club owned". The FAA answered that the question is "more easily resolved by looking at how the aircraft is being operated". The 100-hour applies "regardless of who legally owns the aircraft".
Can the aircraft fly on past 100 hours?
For rental, yes. The FAA's 2015 letter worked through an aircraft at exactly 100 hours that the school could not inspect for three days. It was marked rental-only, and renters flew it another 12 hours. The FAA found no violation, "as long as Fly By Knight is not providing the pilot". It may not fly paid instruction again until it has been inspected.
For instruction, only to reach the inspection. 91.409(b): "The 100-hour limitation may be exceeded by not more than 10 hours while en route to reach a place where the inspection can be done." The same 2015 letter is blunt about what that does not cover. "The 10-hour grace period does not apply to local training flights." A planned solo or dual cross-country at 99.8 hours that is not flown to the inspection is a violation as well. The letter excuses one case. A dual cross-country planned at 3 hours, with 3 hours left, ran to 3.1 hours on vectors and wind. That was no violation, because the crew "did not intentionally overfly the 100-hour limitation".
When is the next one due?
This is where the FAA and EASA count differently. Under 91.409(b), "The excess time used to reach a place where the inspection can be done must be included in computing the next 100 hours of time in service." An aircraft inspected at 105 hours, after 5 hours flown en route to the inspection, has its next one due 95 hours later. The 2015 letter adds that calling the inspection an annual instead "makes no difference". Under EASA's minimum inspection programme, the 10 hours are a tolerance and "The next interval shall be calculated as from the time the inspection takes place." An aircraft inspected at 105 hours has its next one due 100 hours later. An inspection done early restarts the count from the inspection under both rulebooks.
When is the next 100-hour due?
| Case | Done at | FAA | EASA |
|---|---|---|---|
| Inspected early, at 92 hours | 92 h | 192 h | 192 h |
| Inspected late, at 105 hours | 105 h | 200 h | 205 h |
The hours are "time in service", which 14 CFR 1.1 defines as "the time from the moment an aircraft leaves the surface of the earth until it touches it at the next point of landing". That is neither the Hobbs nor the tach. Which meter a club's logbook uses as its stand-in is a question for the club's mechanic, and our Hobbs vs tacho guide explains why the two run apart.
Annual or 100-hour: does one count for the other?
An annual counts as a 100-hour: 91.409(b) asks for "an annual or 100-hour inspection" within the preceding 100 hours. The reverse is not automatic. 91.409(a): "No inspection performed under paragraph (b) of this section may be substituted for any inspection required by this paragraph unless it is performed by a person authorized to perform annual inspections and is entered as an "annual" inspection in the required maintenance records." The difference is who signs. A mechanic with airframe and powerplant ratings may do the 100-hour: 65.85 covers the airframe and 65.87 the powerplant and propeller. An annual is typically signed by the holder of an inspection authorization (65.95). Doing the 100-hour that falls nearest the annual's due date as an annual, by an inspection-authorization holder, is one way to keep the two in step. What either costs at a shop is in how much does an annual inspection cost?
What EASA Part-ML asks instead
A club aeroplane that is an EASA aircraft of 2,730 kg maximum take-off mass or less, and not listed on the air operator certificate of a licensed air carrier, falls under Part-ML (Regulation (EU) No 1321/2014, Annex Vb, point ML.1). Each aircraft is maintained to an aircraft maintenance programme (ML.A.302). That programme contains either the tasks of the minimum inspection programme or the manufacturer's instructions for continuing airworthiness.
The minimum inspection programme, ML.A.302(d), sets the interval for aeroplanes "every annual or 100-h interval, whichever comes first, to which a tolerance of 1 month or 10 h may be applied". That applies to the aircraft, not to the flight: a privately flown club aeroplane on the programme gets its 100-hour just like one used for training. A programme built on the manufacturer's instructions uses the intervals in those instructions. And for aircraft operated by commercial training organisations (ATOs and DTOs), or not operated under Part-NCO, ML.A.201(e) requires the operator to be approved as a CAMO or CAO, or to contract one, and to have all maintenance done by approved maintenance organisations; a non-commercial club DTO flying under Part-NCO is not in that group. Which programme your aircraft is on is set in its maintenance programme, declared by the owner or approved by the CAMO or CAO (ML.A.302(b)).
Tracking it in a club
Either way, a club needs two numbers per aircraft: the meter reading at which the next 100-hour falls due, and the date of the next annual. That is what maintenance tracking in Pilot-Next keeps. A maintenance plan has an interval in hours, in months, or both, whichever comes first. Under the FAA rule a 100-hour does not count as an annual, so set them up as two plans: the 100-hour on hours, the annual on months. On EASA's minimum inspection programme one plan on both, whichever comes first, matches ML.A.302(d). Every settled flight moves the meter: the Tacho, or the Hobbs on an aircraft without a Tacho. The plan turns Due Soon in the last 10% of its interval and Overdue once the reading or the date is reached. Pilots see the next item due on the schedule while they book.
When the inspection is signed off, Pilot-Next sets the next due reading to the reading at sign-off plus the interval. That matches EASA's minimum inspection programme and an early FAA inspection. After an FAA overrun en route to the shop, the administrator lowers the next due reading in the plan by the excess, so the plan shows what 91.409(b) counts.
Nothing in this guide is legal or maintenance advice. Each FAA letter answers the facts of one inquiry, and your mechanic, inspection-authorization holder or CAMO signs for the aircraft.
