So close I can almost taste the avgas....

It's been another week, and it's still almost done. Why isn't it completely done? Because the replacement nose wheel arrived and turned out to be the wrong one. It's too small.

I don't have all of the details. As near as I can tell, the most likely reason is that the illustrated parts catalog for my plane, or IPC for short, has two different wheel assemblies listed on the same page. This is because the IPC covers more than just my airplane. I use the word "assembly" because the wheel is in two halves, and there are other parts like the bolts that hold those halves together, the bearings, etc. I suspect that whoever Preston was talking to thought he meant the smaller of the two and that's the part numbers Preston was told to obtain.

To add to my confusion, my POH notes that there are two different tire sizes that my plane can have. My plane has the larger size, but the original equipment list says it came with the smaller size. The most likely explanation I can think of for that is that it did originally have the smaller tires, but that Beechcraft installed the larger tires at the same time they upgraded the engine to the O-360. With that larger engine came a larger propeller and the larger tires provide more ground clearance for the prop.

Thing is, as far as I can tell, both size of tire used the same wheel. It is only the outer diameter of the tire that is different: 15 inches vs. 17.5 inches. Both mount on a wheel six inches in diameter. The smaller wheel in the IPC is five inches in diameter and I'm assuming that's the one that was sent to the shop.

I went out to the shop this past Saturday and they had put the new tube and tire on the old wheel, and mounted the wheel on the nose gear so they could at least have it on the landing gear and move it around. When I arrived, the mechanic was just about done connecting everything. All that was left was to re-install the front seats and put the cowl back on. He was hoping to have it running later that afternoon. I haven't heard yet whether or not he did, but I may call tomorrow and find out. They had also received the new clear cover for the landing light and installed it, replacing the old one which was cloudy and yellow. The cover for the taxi light on the right wing wasn't replaced, but it's not as critical, and isn't in as poor a condition as this one was.


In the mean time, Preston's trying to figure out what's going on and get a wheel of the right size. Hopefully one can be found and delivered quickly. It would be really nice if I could have my plane back this week, though the weather has been mostly cloudy with some rain. Though there have been a couple of periods the last couple of days where it was nice enough to fly around the pattern, which is what I'll be doing on the first flight just in case something goes sideways and I need to land.

Predicting the weather is hard

At least, it's hard for this region of the country. I like to say that predicting the weather for the Puget Sound region is far more an art than it is a science. Early last week, the weather forecast was for pretty much crappy weather for the foreseeable future. However, because of the chaotic nature of the atmosphere around here, especially at this time of year, the forecast is always subject to change. As it turns out, the weather was actually nice enough last Friday afternoon (December 17) that I was able to go up for about an hour and a half. One of the reasons I went up was because I had filled the tanks after the previous flight, and I wanted to burn off some fuel in case I was able to take my father flying while we visiting from Arizona. As I'm sure I've mentioned, the weight and balance of my plane is such that I'd be over maximum weight if I had a passenger in the front seat, the required ballast in the baggage compartment to stay within the forward CG limit, a...

A digression, if I may...

The other night, after almost 50 years, the Saturn V was dethroned as the most powerful rocket ever successfully launched by humanity. I use the word "successfully" because the Soviet N1 rocket actually generated more thrust at liftoff, but all four launch attempts ended in failure. For the first time since Apollo 17, a true moon rocket lifted off from Kennedy Space Center in Florida, carrying a spacecraft capable of carrying humans back to the moon. This Artemis mission is a test flight, so no astronauts are on board the Orion spacecraft. Despite that, it was a spectacular launch. Because the SLS launch vehicle has a higher thrust-to-weight ratio than the Saturn V, it rose from the launch pad much more quickly than it's predecessor. I think it's a bit heavier than the Space Shuttle, but it has more thrust due to an additional RS-25 engine, and more powerful solid rocket boosters. Watching it rise into the night sky, I was excited, but also a bit melancholy. This was ...

Approaching the annual

I know I haven't been posting much, but that's mainly because nothing much of note has been happening. I've been flying, but not really going anywhere in particular. The engine continues to run very well, and the plane is still solid. I was hoping to do more "destination" flying this year but, for whatever reason(s), it didn't really happen. Next year, hopefully.... On the horizon, though, is the annual inspection. It's already scheduled for mid-December, since the last annual is good to the end of that month. I've also arranged for it to be an owner-assisted annual. I'm told that every airplane owner should do this at least once and I can certainly understand why that is the case, even before I do it. I will be learning about my airplane in a way that nothing else will match and, incidentally, save some money at the same time. I'm looking forward to it. Leading up to the annual, I have been compiling a list of squawks that I want to take care ...
