    More Aileron stuff

    Group,

    I am putting together a list of part numbers for my Sundowner M2226,
    working toward replacing the bushing nut bolts etc on the ailerons
    etc. I broke down and bought the parts book for my plane. However, I
    cannot find the part number for the bolt that insets into the
    aileron rod ends for end rod 169-380082-3. Can anyone help. Also,
    where is the best place to get the items listed below? I would like
    to get close tolerance on all these items if possible. Thanks

    I figured I would put the list together so it may be posted on BAC
    for future reference. See below.

    C23 (M-1971, M1980 and after) and Sierra 200 C24R (MC533,MC537 and
    after.

    More Aileron stuff

    Happy New Year, everyone!



    I have not seen any responses to this so far. We returned home to SC
    yesterday afternoon. Not a fun flight up from FL, and including one missed
    GPS08 approach here in Laurens. That was my first-ever miss on the GPS08,
    and we were dead on track. Never saw a thing the first time, but made it in
    on the second try about 30 minutes later. But that's another story. Not
    sure I'll ever get Paula in the plane for an IFR ride again, though. Bit of
    a rough trip home.



    Since we got back yesterday, I spent some time on this today. Here are the
    bolts and nuts used for the aileron pushrods on the pre-1978 models of the
    19/23/24. The same bolts are used for all years and models; only the nut
    specification was changed effective with 1978 (see below).



    Forward end: AN24-16 Clevis bolt with AN960-416 washer and AN320-4 Castle
    nut and MS24665-134 cotter pin. Post-1977 airframes use nut #130909N16.



    Aft end: NAS1104-9 short-thread bolt with AN960-416L (light/thin) washer and
    MS20364-428 thin self-locking stop nut. Post-1977 airframes use nut
    #130909N32.



    Note that in this application I would not re-use the thin self-locking nut.
    They are cheap; and with no other form of safetying the aft bolt and nut
    (due to clearances and relative motion), you want the nut to be tight every
    time it is installed. Note that this is a preflight check item. The
    forward bolt, which cannot be readily seen other than during the Annual
    Inspection, has a positive-safety in the form of the cotter pin. There is
    more clearance there, which allows for the pin to be used.



    My new edition of the parts book for the 1978 and later 19/23/24 airframes
    shows the different numbering system for the two nuts, which I am not yet
    familiar with. They carry no MilSpec standard identification that I know of
    (so far), and I have not yet turned up a cross-reference for them. It may
    simply be some Raytheon numbering system aimed at making alternate sourcing
    more difficult (and Raytheon does list them for a modest price). It is very
    hard for me to believe that they are actually significantly different nuts,
    since the same bolts and other parts are being used. They may be some kind
    of commercial nylon-insert or coated nuts. The guy I can ask about them
    isn't available for a couple more weeks.



    The rod ends themselves can either be Beech PN 169-38002-3, or Heim PN HM4
    or AHM4, per Beech SI0858-151. The Heims are readily available, and are
    usually less expensive than the Beech PN. These days I would also have more
    confidence in the Heim brand name. There is no telling who Raytheon might
    contract with to provide the part itself, with Raytheon then putting the
    Beech PN on the package.



    Al, just let me know when you have this in "final form", and I'll be happy
    to post it on BAC as an FAQ, credited to you. Thanks very much for taking
    the extra time to record all this. If everyone chips in like this when they
    can, we'll greatly accelerate the technical content on BAC. These kinds of
    documentation efforts don't require a lot of experience and A&P knowledge;
    just the willingness and persistence to put the list of numbers together.
    Some pix during the work would also be terrific. If you get photos and take
    notes, I'll compile an instruction download. Bill Manhein will then work
    his magic on it for clarity and size, and we'll add it to the list of BAC
    downloads. Might even make a good candidate for the technical page in a
    future issue of the BAC Talk newsletter.



    Speaking of which, the next BAC Talk tech article will probably be on
    repairing the wing fuel sump drains (all styles, including alternatives).
    The one after that will probably be on repairing the fuel
    strainer/Gascolator. The former is complete and ready for the next issue,
    and is available for download from BAC right now. Sump drain O-ring kits
    are also available in BAC Classifieds. The first draft of the latter is
    complete except for the photos and Manhein-massaging. I have accumulated
    all the rings needed for Gascolator kits as well, with the exception of the
    two flat gaskets for the very early-style strainer. The source for those is
    outlined in the document. All seals and o-rings will be available for the
    mid-style and late-style strainers.
