The Malibu & M-Class Owner’s and Pilot’s Association recently released their MMOPA Vision Video. It is a great video detailing the history of the Piper PA46 & the history of MMOPA. The PA46 would have ceased to exist without the founding of the original Malibu Coalition.
Checkout the video above (and Texas Top Aviation’s Hank Gibson even gets a cameo!).
Sadly, in January, a pretty great airplane was put out to pasture. Textron (the conglomerate that now owns Cessna, Beechcraft, Hawker, and Lycoming) announced it was ceasing production of the Cessna TTx. With the end of the Cessna TTx production, an airplane that was the main “competitor” to Cirrus (if you can call it competition; Cirrus consistently outsold the Cessna TTx by a wide margin each year), it leaves the SR series to stand alone atop the High Performance piston single market.
I got to go through Cessna’s FITS Accepted Instructor (CFAI) course back in 2012 and have flown in the Cessna 350 and 400 (which is what they were known as at the time; the Cessna TTx name came around in 2011) for about 120 hours. I really like the airplanes. I’m partial to the Cirrus, but the Cessna 350 & 400 are fast airplanes and great for 1-2 people. I flew a 350 (the non-turbo charged version) from New York to San Antonio last fall and routinely saw 170 knots at 12 GPH.
Columbia started out making the 350 & 400 (the turbo-charged version) in the early 2000s, but went bankrupt in 2007. Lancair started Columbia to make a certified version of their popular kit planes. If you see a Lancair ES floating around, you would swear it’s a Columbia with only 1 door. Cessna bought the design from Columbia in 2007 to begin manufacturing the airplanes themselves.
Cessna then made a huge mistake as they moved the production facility from Bend, Oregon to Mexico. Production completely halted in 2009 as the planes coming out of Mexico were found to have defective composite work. The sales never really recovered, even though Cessna put the Garmin G2000 panel in the Cessna TTx, complete with a touchscreen key pad. A FIKI system was added as an option in 2012.
A prospective buyer can still get a great value on a used 350, 400, or TTx, as they are valued a little lower than a Cirrus. The 350, 400 or TTx all make excellent single pilot or two person speedsters with very comfortable amenities.

For years, there has been clamoring for airplanes to get rid of lead in piston engine Avgas. In the early 2000s, Thielert created a Jet A burning piston engine for Diamond Aircraft that gained some traction, but Thielert had internal issues and ended up declaring bankruptcy. Several other Jet A piston engines have come down the line since then to some success (Diamond is currently using 2 Austro manufactured Jet A piston engines on it’s DA62 and a Continental manufactured Jet piston on the new DA50).
The problem with a Jet A burning piston engine, though, is that those engines would be very expensive to put on existing airplanes, not to mention the cost of the STC alone.
Insert GAMI (General Aviation Modifications, Inc.), the famed Ada, Oklahoma company that championed turbo normalization, balanced injectors, and lean of peak operations. For those that have been to GAMI’s engine class, you know that these guys are at the very top of their game in engine knowledge.
In 2010, GAMI started the process of creating an Unleaded form of Avgas, terming it G100UL (the irony of traditional Avgas, 100LL, is the LL starts for low lead, but the lead levels in 100LL are actually quite high. UL stands for UnLeaded). Just before Osh Kosh in 2021, GAMI revealed that it’s work has come to fruition, gaining an STC for G100UL for Lycoming powered Cessna 172s.
The amazing thing about GAMI’s product is that it is able to mix with 100LL and not cause any issues. This means fuel trucks, fuel lines, fuel pumps, and aircraft fuel tanks don’t have to have any modifications to them to use G100UL. Plus, pilots will see longer engine life using G100UL because of the simple elimination of the lead. In tests, combustion chambers in cylinders burned cleaner, so theoretically, cylinders and engines will last a lot longer.
According to the company, GAMI has a few more tests to run and, assuming those go well, G100UL will be available for a whole lot more airplanes. An STC will still be required for the use of G100UL in a specific airplane, but the hope is, eventually, 100LL will be completely replaced by G100UL. The only downside is that G100UL is expected to cost about $1/gallon more than 100LL.
GAMI has partnered with Avfuel, so expect to see 100UL showing up at all Avfuel FBOs in the next year or two.

When a pilot thinks of an engine runup in a single engine piston airplane, typically it is let’s find out if the engine is running rough or not, meaning a spark plug is fouled. Believe it or not, there is a little more to learn from a runup than just checking the spark plugs.
A distinct advantage to having an engine monitor that monitors all EGTs and CHTs is you get a better idea of engine health. When switching to one magneto or the other during the runup, all the EGTs should rise, showing that the temperature of the exhaust gas is going up from each cylinder. This occurs because when running on only one magneto and one set of spark plugs in each cylinder, the mixture takes longer to burn, so, when the exhaust valve in the cylinder opens, the burn is still on going and this hits the EGT probe, causing a temperature rise. An indication of a magneto failure in flight would be a rise in all the cylinders EGT without a change in mixture setting.
Now that we know what to look for when checking each magneto, what would one look for to show that there is a problem? The basic that each student pilot is taught still applies. The engine manufacturer puts a limit on RPM drop during the runup. When checking one magneto or the other, watch for an excessive RPM drop. If the RPM drops past the limit, this usually will be accompanied by engine roughness.
Why is that? Let’s look at the cause for the excessive RPM drop. For this, we need to go back to our EGT indicators. Let’s say we have a 6 cylinder engine. When the key is turned to the right magneto, the RPM drops 250 RPM and the engine gets very rough. Look at the EGT gauge. The cylinders where the spark plugs are firing normally will all show a temperature. The cylinder (or cylinders) where there is no combustion, meaning a bad plug, will show no temperature. This is because the mixture is just sitting in the cylinder and not igniting, therefore, no exhaust gases will be pushed out so there will be no EGT indication for that cylinder. This is also how you tell a mechanic which cylinder to check for the bad plug.
It could also be a bad magneto. If multiple cylinders EGT all drop, or the engine wants to quit entirely, you have a bad magneto or bad ignition harness.
What else can you learn during the runup? Electrical system health is key, especially in all electric airplanes (meaning no vacuum system). It’s a very good idea to turn on all the lights and pitot heat to ensure that a rise is indicated on the ammeter. This means the alternator is carrying the load and working properly.
The next time you do your runup, keep an eye on your EGT to see the rise during a magneto check.

Late last year, the Diamond Aircraft Corporation announced a brand new twin engine, the Diamond DA62. At first glance, this is a pretty cool airplane. It seats 7 passengers, spread out amongst 3 rows, with 2 massive doors, leading to an “SUV” type feel, according to Flying Magazine. That is only one of the “neato” features of the Diamond DA62.
The thing that will make pilots believers is the fuel burn. According to Flying Magazine, which did a test flight of the airplane, at 14,000 feet and 60% power, the airplane was only burning 12 GPH, but still doing 170 KTAS. Remember, this is a twin. That’s about the same as a normally aspirated Cirrus SR22 at the same altitude.
How does Diamond do it? Jet A. The company put two Austro AE330, 170 Horsepower, Jet A burning piston engines on the Diamond DA62. You may say, well, yeah, at 60% power, that’s great, but I want to go places. How much fuel does it burn then? Even at max continuous power of 95%, it’s still only burning 18.5 GPH total and cruising at 195 knots. Paying Jet A prices, that’s pretty sweet.
The range on the airplane is quite nice too. Again, according to Flying Magazine, the range with full fuel (86.4 gallons with aux tanks) is about 1,300 miles. You can carry the whole family too, as the full fuel payload is 1,000 pounds. Golf clubs? No problem. Just stick them in the nose.
The Diamond DA62 is probably one of the easiest twins to manage, engine-wise, too. The Fully Automated Digital Engine Control (FADEC) system that Diamond installed leaves the pilot with only 2 power levers, instead of 6 on the typical piston twin. All that needs to be done at cruise is set a percent power and the FADEC computer does the rest.
Need air conditioning, built in oxygen, and TKS? Diamond can set you up. The G1000 system complete with digital backup instruments is standard in the airplane. What more can you really ask for?
If you haven’t figured it out, I really like this airplane and would be aching to fly it. I enjoy the DA40 and have a good amount of DA42 experience, but I’d really like to hop in a Diamond DA62.
