Did Mooney change the format of their S/N's at some point. I'm looking at the serial number range the SB applies to and the format is very different from mine. My SN is 22-1421. The SB applies to SN 680001 - 680206 and a few other F's. Does that mean it doesn't apply to me or that there are two SN's?

They had a straight 3-4 digit S/N until about 1966 when they changed to the long format with the first two digits being the year.  Then they switched again in 1971 to a S/N with a 2-digit prefix indicating the model followed by a 4-digit number.

Do you know if the cable design changed. As I recall (off the top of my head) my cables are solid steal threaded on the end. Perhaps the older Mooneys used twisted cable? I could see those wearing out. In fact I had that happen while landing an Aeronca. The twisted cable snapped inside a tube the prevented inspection.

Sorry, I don't know.  My 1963 M20D already had the cables replaced by a previous owner so I've never seen the older style.

Isn't the McFarlane made cable done under owner manufactured?

 

Also, what does Maxwell charge to do the replacement? I will bet that's an ethereal figure!

Look at the figures I wrote above. I already did all the footwork. SWT was tge lowest bidder. They order it through Mooney, who orders it from McFarlane; however, because it goes through Mooney it is FAA-PMA approved.

Yes. Your 1976 F is near the last of the 22 series F models built.

My O got a new cable two years ago...something about the design of the '94 cable...

That makes it an Older Mooney...

Best regards,

-a-

my O got a new cable a few years back as well, after failing in flight. Made for a bit of excitement.

When a throttle cable fails would it still go open but maybe not close?? I'm just curious, as to what one might expect.

It will most likely fail at the fully closed position because it happens when you pull on the knob. My first instinct was to put the throttle rod back and push it in but then I realized that I would have placed it in the full open position (depending how far I pushed it in).

When I removed the cable and inspected where it broke, I noticed that it was right at the base where the wire meets the swiveling rod closest to the knob. While the rod was in the chamber it stopped swiveling but while removed, it swiveled just fine. I suspect pilots who flew the aircraft in the past tried to twist the knob as if it was a vernier knob and the twisted wire that was not turning properly began to fray.

I just got off the phone with the following companies:

Spruce: Does not carry the part as per the SB

LASAR: 540 for the throttle; prop is 376

Maxwell: Prop 570; throttle 485

Southwest Texas Aviation: Prop 368; throttle 332 (10 day lead time because they order it straight from Mooney who is right down the street. He said mooney has the cables made by McFarlane but since it goes through Mooney they will be FAA-PMA approved)

I spoke directly with the owner (Russell) who was very helpful. Company number is 800-749-7982.

I didn't need to buy the mixture control cable because the SB only requires it for the E and F model.

That's what I did... I ordered the prop cable from SWTA and it was drop shipped from Mooney. When I opened it up I was surprised to see McFarlane made the cable.

Finally got my cables in directly from Mooney :) I is also nice to have knobs that are properly colored ;)

It took and extra week due to WX. Funny to se that Mooney doesn't even bother to take the McFarlane stickers off, lol!

I did notice that the prop cable is smooth as butter ;)
