plat and higher <| sep |> Don ' t like either much but I ' d go Lewis . <| sep |> So what ' s the alternative ? There ' s no crop that ' s really going to take its place and I see no reason to pursue one considering how useful corn is . <| sep |> and they don ' t stop coming <| sep |> I break it down like this , there are two types of reoccurring AD ' s . There are the visually inspect something , or move something to make sure it is still ok . These in my mind is are not a big deal . Examples include inspect the controls for freedom of movement , or inspect fuel lines for wear . These are not a big deal and do not add any significant cost , and really are a good thing . Every plane has a ton of these . The second type is the something must be done type most planes seem to have 1 or 2 of these , its just how much must be done . The Comanche line has 2 of them across the line . Some odd models may have extras such as the prop AD on the 250 ' s . But these two are the ones people are concerned about . nbspThe first is what is referred to as the Landing Gear AD . AD 771321 . This has 2 parts to it . If you are shopping one make sure both part A and B have been done . Part A occurs every 1000 hours . It requires the disassembly of the landing gear and replacement of any worn items . This is probably a good thing , as every 810 years to check for worn parts and replace those that are worn . If you have any retract and are taking care of it , you likely would replace the same parts over the same time period anyway , so I consider it good preventive maintenance . The book time is 6 hours per gear leg to do this . I think last time my mechanic did it in 4 or 5 each . So you can budget for 1518 hours of labor plus parts every 810 years . Part B occurs every 3 years or 500 hours which ever occurs first . This requires the replacement of the bungees in the landing gear . The bungees serve to assist in extending the gear in an emergency and reduce the load on the gear motor . The bungees cost approx $ 60 for a pair and take less than an hour to install . I replace mine every year because I feel it is better for the gear motor . This is not a big deal for an AD in my opinion . nbspThe second big AD everyone talks about is the Stabilator Horn AD . 20121706 . This is the new one that everyone freaked out about . Its not that big of a deal . Some of the horns are getting cracks from being improperly torqued and the load . It takes about 68 hours to comply with this AD . This AD is a little more confusing to explain compliance , but there are 3 methods of compliance . Compliance method # 1 500 hour option cheapest Visually inspect the inner surface of the Stabilator Horn for cracks every 500 hours . If no cracks are found , put it back together and go fly for another 500 hours . Compliance method # 2 1000 hour option Replace the stabilator horn with a new one from Piper , you are not required to reinspect for another 1000 hours after a new horn is installed . After the initial 1000 hours , it must be inspected every 500 hours . This is really the worst method of compliance for this AD . Compliance method # 3 makes a lot more sense if there are cracks found in the Stabilator Horn . Compliance method # 3 Its fixed forever option Replace the stabilator horn with the Australian Stabilator Horn that has an improved design . This discontinues the AD and does not require any reoccurring inspections . I think the stabilator horn is pretty pricey at a few thousand dollars , but it is not break the bank expensive . nbsp If you have any questions or want to chat on the phone sometime with questions or specifics feel free to shoot me a PM .
