    Its written in the AD you linked:

    (2) Before further flight after completing the action in paragraph (g)(1) of this AD, calculate the factored service hours for each main wing spar using the following formula: (N × 100) + [T-(N × 100)]/17 = Factored Service Hours, where N is the number of 100-hour inspections and T is the total hours TIS of the airplane.

    Might want to ask if the Piper Service Bulletin has been accomplished. The AD is just proposed at this point.

    Look for one less than 5000 hours, just how many hours are on the one you are looking at?

    Looking at the proposal, some places say 5,000 hours and in the examples, it states "factored service hours", and if the plane hasn't been used for training 12,100 hours becomes 711 factored service hours, so if the plane hasn't been used in flight training alot, it would take a long time to get to 5000 factored hours

    I would not buy a PA28 right now..... that’s like buying PG&E stock today.

    Not necessary if it has not had a lot of 100 hour inspections. Our Warrior has 5200 hours and has had 34 100 hr inspections in the past which makes somewhere around 3500 hours factored time in service.

    Based on what information do you say that?

    Based on the fact the FAA is trying to rake the airframe over the coals. You can try and act like it won’t do anything, but you and I both know that if you try and sell your plane and it has not received this AD inspection, any buyer with more brains than money would balk.

    My little piper has 3001 total hours, and NO 100 hr inspections.... The wing spars are corrosion free, and tight.... NOT ready to go do the NDI inspection for the rest of the time I own the plane!.... Hope that will be 30 years.

    There is no AD, only a Service Bulletin currently. With our plane the AD would consist of the I/A calculating the factored time in service and signing the airplane as air worthy. End of story.

    We are selling the plane to a club. We are having the SB done. If nothing shows up the deal will happen.

    For the purposes of this calculation is an annual inspection equivalent to a 100Hr inspection?

    The way I read it, no. And therein lies the problem. Using a 100hr inspection as a means of determining what an airframe has been through in a prior life is poor at best. The flight school local to me does annual inspections every 100 hours and as the AD is written, their airplanes would be able to be treated the same as ones that were never operated for hire.

    PG&E stock... they are not going anywhere, they have a long history with Gain Newsom who has been very friendly to them and took a lot of campaign money from PG&E and many of its top executives...? Wait until they drop to $2.50 a share and buy.. it will only go up from there.

    PA28 on the other hand... think I am going to hold off on this for a while to see where the dust settles...

    I guess we will see where they end up after the BK is settled.....

    By contrast our Warrior had a slew of 100 hour inspections done and signed by an A&P and then an annual sign off on the same day and tach time by an I/A.

    It happens. My friend has an Archer with a couple 100 hour inspections in the logbook for the same reason despite the very low total time. Thankfully in his case the total time is so low and the number of 100 hour inspections are so few that it won't be much of a detriment when it comes time to sell but it is still going to be a factor.

    I really hope that the FAA and Piper come up with a better solution for determining when to perform this inspection if it becomes an AD.

    I did some figuring using the formula. If the plane has another 5000 hours put on it with no 100 hour inspections it will never trigger the additional inspection.

    So to add to this, where would a 50 hour inspection lie.... that is about 6 of them in one year.. would it be safe to say this would be treated as 3 100 inspections?

    I did the math on my Cherokee today. It was used as a trainer extensively in the first 20 years of its life, and it has had a fairly leisurely life since then. It has about 6100 hours and 40 100-hour inspections. This came out to about 4118 factored hours, which doesn’t sound great. Interestingly enough, if you use a little algebra and assume 100 hours a year in the future, it will be at the factored service life of 5000 hours in about 149 years. If my math is correct, the sky is not falling.

    Mine is at almost 5900 hours and comes to a factored life of 2200. If they leave it as is I will be happy.

    Buy a Cherokee made at Lock Haven. None have failed wings.

    More King Air wings have fallen off than Cherokee!!

    When did the stop making them in Lock Haven? I know there was a flood there in 1972.... Hurricane Agnes, that made them move some of the production to Flora - duh! and the Tomahawks were the last plane built there.. did they keep the PA28 there until the end as well?

    To tie up a loose end. SB1244c was performed on our Warrior by an A&P I/A that the club we're selling to chose. We closed on the sale Tuesday afternoon. We subtracted the cost of performing the SB form the price and closed at $39k. 1976 Warrior with 5200TT and 1500 on the engine, no ADSB out and a Garmin 430W

    PA-28s were never built at Lock Haven. Piper already had a development center at Vero Beach, and the factory there was built in 1960, specifically for Cherokee production. All PA-28s have been built there, other than those assembled under license in South America.
