@DonMuncy makes some nice ones

Age is a factor, as is weight on the pucks. The pucks are rubber, and volatiles migrate outsider time, leading to stiffer, less flexible pucks. Weight on the pucks will compress them over time, making it difficult for them to expand enough over time. Combining these two effects is what we see. Keeping weight off the pucks should extend their life, but there is still the age-hardening effect. No one right now knows how much each contributes to failing the test at annual, or to partial retraction like I experienced in my C. But temperature definitely effects this--mine started occasionally one winter, stopped over the summer and began in earnest the following winter. Replacing the pucks made all of my problems stop immediately. Stupid horn sounded off for over an hour on one flight, and I was 10-15 knots too slow, then at the top of descent when I pushed the yoke to descend, felt and heard a small thump, the horn stopped and the Gear Up light came on . . .

@takair may know.

It's great to see someone seriously pursuing this! Many (most?) of our Vintage birds had the PC system installed at the factory, then added the autopilot by STC, but they still use the same factory servos. Memory says the PC system was introduced in '65, but I know it's in the Owners Manual for my 1970 C. This won't affect your PMA, but it should make it easier for people to purchase and install your boots.

If McMaster Carr (www.mcmaster.com) doesn't have one, check MSC (www.mscdirect.com)--if MSC doesn't have it, you don't need it, but McMaster has friendlier pricing.

Looks like the boot is torn, as far as I can see in the picture. Check this thread for the latest updates on new boots: https://mooneyspace.com/topic/49966-torn-brittain-servo-boot/page/2/#comment-938084

Us carbureted folks just cut them open when we have a few minutes to spare, and a bucket to empty it into . . . I save my energy for loading and unloading my wife's baggage . . . .

Harbor Freight pipe cutter works, too, just measure the oil filter so you can buy the right size.

I found mine on the side of my freshly-replaced nose tire. I'll be replacing my mains next week if you need any . . . .

I'll be heading down in late March and expect to stay about a month. Which is the most convenient field to use? Any ideas on tie down rates? Is it safe to park outside all of April? (what's the weather like? Hurricane season won't start for a while.) Thanks for your advice. My only experience there was FXE for tank reseal more than 10 years ago.

The emergency gear extension mechanism and little bronze gear (if electric); the Johnson bar and handle innards if manual. Overhead vents and covers. Roof vent horsehair to separate water out of the incoming air. PC servos. Off the top of my head . . . .

Do you have a 12-year-old daughter? Or know someone with equally small hands? That seems to help. Can't get my hands in there . . .

Sounds like they are finding a trail position for you, all by themselves. Any idea how far they open? Many advocate for ~1/2" -- 3/4" gap when closed.

I HATE electrical troubleshooting!!!

For those nice sunny summer days, And for those bright winter days, Other similar ventilated models work well for hot days with forecast rain. These work well even against sun from as far back as 8 o'clock behind you, and of course that nagging bright furnace an inch beyond your sunvisor. Even better, these sun visors continue to protect your eyes after exiting the airplane!
