    This is a 172, total time 2760.
    Owned by a CFI, The owner had the aircraft annulled at 2725 hours Total time. The owner flew the aircraft for his own pleasure for 10 hours. (not for hire) then 25 hours flight instruction.
    When is the next 100 hour due.

    Didn't we just have this question last year? 2825.

    Really? Someone who continually tries to convince everyone how much of a maintenance expert he is should know the answer.

    91.401 (b): "Except as provided in paragraph (c) of this section, 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..."

    preceding 100 hours of time in service
    not
    preceding 100 hours since it started getting used for hire

    I do.

    The owner can carry persons for hire until the 100 time limit is met. Then they can operate the aircraft "Not For Hire" until the next annual is due.. They are not required to ever do a 100 hour again.
    Plus the aircraft can be rented by anyone during that time.

    Then why ask the question? Trying to demonstrate your knowledge to the rest of us or convince us of something?

    Or maybe simply a quiz to provide discussion. Turn your shirt right side out again and calm down.

    Because some of us like learning instead of making snarky comments.

    Move on if you have no interest in the discussion - and take your negative attitude with you.

    what a way to go thru life....

    The reg is very clear and it has been discussed many time before so what is the point in asking such a question? With the exception of teachers in a classroom, normal people usually only ask questions when they don't know the answer.

    Because two people got the answer wrong. If you educate two people with a simple question, what the hell is your problem? I am a professional educator and I do a lot of forensic work on my quizzes and exams because one of two things is out of kilter --- either I didn't teach it right, or the student didn't hear it right. The problem is to figure out which one.

    Normal people don't always throw a tantrum when they don't like a question.

    Gotta remember the regulation says 100 hour or Annual. (and a couple other inspections) The aircraft I see that are for hire don't get 100 hours per year. And one customer has me do an annual no matter how much time they get. one year I did three annuals in the 12 month period.
    CFI's that own their own aircraft, most every one is different.

    "Didn't we just have this question last year? 2825."

    That is not the right answer. Not the wrong answer, just it assumes facts not in evidence as them liars (sp?) say.

    Depends on what you assume.

    If you assume that the aircraft continues to be used for flight instruction or other for hire activities past 2825 hours then those who answered 2825 are correct.

    However, if the aircraft is not used for flight instruction or other for hire operations past 2825 and before the next annual then a 100 hour inspection will not be required.

    This is the problem with these all too frequent questions that some folks like to post on here. They lack enough specificity to allow anyone to provide an absolutely correct answer. The OP made no mention of the use of the aircraft after the 35 hours (10 + 25) described. So the only correct answer given the information provided is "it depends".

    That is why I tend to "disrupt" these things at times. Because a question is poorly formed and requires assumptions in order to be answered. Then if someone makes the wrong assumption but provides the correct answer based on that assumption, they will be called wrong because the assumption was not what was in the OP's or even another reader's mind. I've seen this again and again.

    I was wondering who would comment on that. I let it go as I didn't want to be too disruptive. :D

    If guess it depends on your perspective. Since a 100hr is not required for a Part 91 aircraft, the only time that question would be asked is to comply with 91.409(b). Otherwise there's no basis for the question. So from my perspective the only answer is 2825 regardless what type of flying was done in the preceding 100hrs.

    I think there is an inspection that can be done instead of an annual or 100 hour inspection that meets FAA regulations that I haven't seen mentioned.
    Any thoughts on this?

    If it's your plane you can do a 100 hour inspection after each flight if you like. Just do the annual when it's due to keep it airworthy.

    Only under your twisted logic. Irregardless of what operation does not require a 100 hour inspection, the 100 hour is due for those operations requiring a 100 hour inspection.

    Heck, do an annual and fly the plane less than 100 hours each year it is never due.

    Much more learning would be done if the questioner followed up with a clear concise answer, which in this case never happens. More often than not as soon as good answers are provided, he changes the details to change the correct answer, which would also be fine if he didn’t try to be over clever and “tricky”. He also never, ever, at least that I have ever seen, provides an unequivocal answer himself, he leaves it open to conjecture, which means nobody learned squat from him. At best they figured it out themselves, which they could have done without the silly made up question.

    I have come to this conclusion after trying dozens of times to find value in one of these exercises.

    Maybe the OP should start a blog to get his various educational musings out in a more direct manner. :)

    Well...… if it flies less than 100 hours in a year, then it is never due.

    Do progressive inspections and neither an annual nor 100 hour is needed.

    If you want the right answer you have to ask the right question. Trick questions are for people with a superiority complex. Dumb thread.

    The question assumes that it is required, therefore the answer does.

    Trick questions don't condone learning, they condone belittling.

    Besides it's something every student pilot is taught. How about I start a thread asking what is the stall speed for a Cessna 172 with full flaps? Vs0 you answer? Wrong! Angle of attack makes an airplane stall which can occur at any airspeed. See how much smarter I am?

    I truly understand your point. The question can definitely be read to imply that a 100 hour will be due at some time and is then asking when that is. And presuming that, the answer of 2825 would be correct and I have no issues with those who answered it that way due to the wording.

    But as noted, if the aircraft does not hit 2825 before the next annual or if it is not flown for hire after reaching 2825 if it does reach that mark before the next annual then a 100 hour would not be required. Again, it's another typical vague or poorly written question/scenario by this OP. And that is why his questions and those by some others bug me.

    It's almost as bad as asking how many days an annual is good for.

    The question was perfect for the person who it was written for. They understood it. and got the answer they were looking for.
    You see, many pilot/owners won't log in because of the attitude of some here, but they do read.

    Normally when people ask questions the person wanting the information is the author. In your post you pose an illogical question for the purpose who knows what.

    Yeah, typically people who ask questions want answers for themselves or "for a friend." Quizzes are nice but it's better to be upfront and say it's a quiz. It gets the folks being targeted - those who are not sure of the answer and are willing to take a swipe. And it helps those who know the answer avoid stepping on the discussion.

    But here, neither the "stealth quiz" nor the question itself is that big a deal. There's a lot more nuance to the 10-hour overflight portion of the rule and the paid instruction parts of the rule than the relatively straightforward "unless within the preceding 100 hours of time in service the aircraft has received an annual or 100-hour inspection." Unless of course someone want to make it complicated.
