[UND84]

I have a question that is not hard to answer but I am a bit confused on. I am taking my private check ride tomorrow and I need to know about the maintenence rules on the propeller. Is a cessna 152 used under 141 and 61 required to have an annual and 100 hour on the prop. I say this because in the log it shows only 100 hours for over the last year or more. In a 172 at the same fbo there are only 100 hours recorded for the prop log as well. Do they only need 100 hours or is something fishy here? Thank you.

If I remember correctly, a 100 hour inspection takes the place of an annual. In other words, if you are doing 100 hour inspections, you don't need to do a separate annual. (As long as at least one 100 hour inspection is completed every 12 months.)

Again, it has been a long time since dealing with this stuff, but I think this is correct.

I thought an annual can take the place of a 100 hour but a 100 hour cannot take the place of an annual.

Right you are! For the original question, most single engine airplanes with a fixed pitch prop don't have a separate propeller logbook. While it's correct to sign off annuals in each separate logbook pertaining to the airplane, most IA's just make an entry in the airframe logbook. The engine logbook should have either an annual or a 100 hour inspection signed off at the time of the annual inspection on the airframe. The engine signoff is understood to include the prop.

I’m certainly no maintenance expert. But since it’s late and you need it bad I’ll try and help. 91.409 says that a 100 hour inspection can NOT take the place of an annual and also states that aircraft for hire must complete 100 hour inspections. It also goes on to say that an annual can count as a 100 hour inspection. So you might need to look in the aircraft log (not the schools mx book) and see if within the last year one of those 100 hour inspections was signed off as “annual.”

Good luck

Maybe the annual engine includes the propeller. Also, maybe the 100 hour is only written in the prop log because the 100 hour is based off the tach time which is prop time. So maybe they are just keeping track of the 100 hours in that log? Ill figure it out. Thanks.

An annual can be in Leau of a 100 hour, but a 100 hour can never replace an annual

i assume you have access to the log books for this check ride. just check to see (in the logs) if the ads have been checked. if this is a school plane, it NEEDS a 100 hour. if its a club plane, a 100 is optional, but most do it anyways. a 152 has reoccuring (sp?) ads, so it should be having 100 hr checks for that very reason. good luck.

That's correct. One thing to watch out for in the logbooks, though. The 100 and annual inspections are pretty much identical. The real difference is who can sign off on it. An IA needs to sign on the annual. That's why the annual can replace the 100 but not vice versa.

The thing to watch out for is that once in a while, the inspection will be done as an annual, but the shop will put the wrong sticker and signature in the logs. I had that happen to a student on the morning of his private checkride. Goes though the maintenance book and finds no current annual. Turned out it was sticker-it is, but no one caught it before my guy.

On the original question, it could be one of these errors. Also, remember that the separation of the maintenance logs into airframe, powerplant, and prop and the recording of the inspections in each is a matter of logical convenience. Airframes last longer than powerplants, powerplants last longer than props (hopefully). The examination of the prop itself is part of both inspections. As varicam suggests, look at the last annual in the airframe and powerplant sections and see if it mentions the prop.

(BTW, does the prop log entry say "a 100 inspection was performed" or is it just showing an inspection every 100 hours?)

Annuals v. 100-hours

I second everything written above. Pursuant to 14 CFR 91.409, all aircraft must have annuals. 100-hour inspections are also required for aircraft used for flight instruction for hire:

(a) Except as provided in paragraph (c) of this section, no person may operate an aircraft unless, within the preceding 12 calendar months, it has had --

(1) An annual inspection in accordance with part 43 of this chapter . . . . 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.

(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 the aircraft has received an annual or 100-hour inspection . . . .

An annual can count for a 100-hour, provided that all things required by the 100-hour are covered, but not vice versa. In any event, prop would be covered in inspections.

Hope that helps a little more. Good luck with your practical. We look forward to your followup post saying that you passed.
