    Flap setting for a B24R 1975 MC360

    Folks, here is an interesting one.

    My Sierra has only TWO flap settings, 15 degrees and
    35 degrees, there is not a 25% setting at all. from
    what I can see. The handbook states that there are
    THREE flap setting ( plus Flaps UP of course) but my
    mechanic tells me the mechanism ONLY ALLOWS for TWO
    settings.
    Anybody any idea's around this??
    Cheers
    HarryR

    Flap setting for a B24R 1975 MC360

    Harry,

    My 1975 B24R has three settings. I think it is
    serialed in the M800s. Maybe there was a change around
    then because it is identical to my old 1978 C23
    sundowner.

    Flap setting for a B24R 1975 MC360

    Most likely, your Sierra has either been improperly repaired, or was mis-assembled at the factory. There was a Mandatory Service Bulletin, later FAA-mandated by AD 78-04-01, that required replacement of the Flap Weld Assembly. I wonder whether there is any chance that someone installed an incorrect ratchet assembly at the time that AD was complied with. Even though the AD did not address that specific part, it had to be R&R'd during the AD compliance.

    The flap control ratchet assembly (PN 169-524043-3 or -7) determines how many "notches" of flaps you will have. All the flaps are supposed to have a maximum extension of 35 degrees, plus or minus one degree, per the A1CE Type Certificate. The -3 ratchet has two notches, and the -7 ratchet has three notches. The -3 ratchet only applies to airframes M0001 through M0554 (no other models or SNs). The Placard that goes on the flap handle, showing the extension positions, also shows only the two notches for these serial numbers.

    If there are other, later airframes that also have only the two notches of flaps, I would suspect we have found yet another example of a mismatch between the Beech parts books, and their actual assembly practices on the line when the planes were built.

    If you prefer three notches, you should be able to legally swap the ratchet assembly with only a logbook entry, as the 3-notch ratchet is the listed part for your plane. Time to call salvage yards?!

    Thanks Mike, I will get that info to the FBO and see
    what they can find out. The mechanic has told me "
    there is NO way that this bracket / mechanism will
    allow for 3 positions" . I will keep yu'all informed.

    Cheers

    Flap setting for a B24R 1975 MC360

    Mike,

    My '63 Mouse S/N M-238 only has two notches. 15 degrees and thirty
    degrees per the POH. Per your note that's what it should have.
    Woudld the three notch ratchet fit my plane? I guess it's not the
    proper part for my plane and I'm pretty content with the two notches
    I have. I'm just curious.

    Cloyd
    President, BAC
