  1. We are an authorized installation specialist of Surefly. No buyers remorse yet. Lots of fans.
  2. we get 124J hoses from Aero hose shop in granite city IL. They are OC, no stated life limit. Some are 15 years old here, still in service.
  3. Yankees start on the other side of that river, here in Alexandria, Robert E. Lee’s boyhood home is just down the street, and it’s no secret why all the war dead are buried in Lee’s (wife’s) front yard in Arlington. pretty good booze availability, but yeah special stuff you gotta get it somewhere else.
  4. The Bluetooth comes from the 275 EIS display so you’re betting that the unit works, just the display goes bad, also the GEA24B must work as well. That’s a pretty narrow set of failures. Personally the only thing I need to keep going is an oil pressure gauge , the rest of it’s nice to have but not critical.
  5. its 1900$. https://www.aircraftspruce.com/catalog/pnpages/05-04532.php?gad_source=1&gclid=CjwKCAiA74G9BhAEEiwA8kNfpQOesqcyZNCgoXpGRkCqSreaEqVcP5P51f-fgDf_d3Lr8qfRYu75pxoCrPMQAvD_BwE
  6. The upper cowling probably, but the lower cowl is a whole bunch of extra stuff such as the landing light wiring, the carburetor air boot, or the ram air door, which takes 15 or 20 minutes of it just to disconnect without it falling apart. the the oil cooler and the hoses that go to that. They’re fastened into the inside of the lower cowl also.
  7. It will double beyond that. Look at the price of a 10–24D master cylinder. I think it’s about three times what it was a year ago. And it wasn’t cheap a year ago.
  8. Well, they refused to use the UMA sensor because it said it wasn’t PMA or STC. But the P-leads are a substandard solution for Rpm pick up.
  9. This is the brake fluid from a Cherokee 180 that we own. I noticed that the brakes appeared to drag and release very slowly, and I thought it was a combination of old brake fluid and brake caliper slide pins that were not lubricated, but this is absolutely astounding. The stuff has the consistency of mayonnaise. Now, if you change this 5606 out for Aeroshell 31 it won’t do that anymore because the synthetic fluid lasts longer and is better at colder temperatures.
  10. Because the lifters get little spots of rust on them and they form little pits and then pits turn into spalling and then spalling turns into cratering and then cratering wears down the camshaft. The cam is a symptom. It’s not the cause. Continental engines we frequently pull the lifters out of them whenever we change the cylinder and sometimes just preemptively look for a pre-buy. They always have little micro pits and some are pretty torn up actually, and the cams are always good, and then you swap out new lifters and you pretty much save the engine. Where lycoming is more of a hopes and prayers kind of Strategy.
  11. I had a client took his plane to a shop at another airport in the DC area, and they handed him a discrepancy list of like $25,000 worth of stuff, but looking at the list it looked to be about 4000 bucks of stuff. When he showed him, the documentation that a few of the write ups were trivial and actually allowed by the manufacturer, or how you could treat the corrosion on the rear wing attached fitting without pulling the wing off, the shop rolled his plane outside told him to go F himself and then faxed the discrepancy list to the Washington FSDO and told him the plane had to leave on a trailer. I fixed the three discrepancies that were legitimate on the ramp and then we ferried it over to my shop and fixed the rest. The FSDO guy said he’s not giving a ferry permit, even though I had inspected the aircraft, so we got the DER that he hired to engineer the wing skin crack repairs to state that it was safe for not more than 100 hours of flight time. Then he called the FSDO and got into a fight with the inspector because he still refused to give a ferry permit saying it was unairworthy, even though the DER says you don’t get to tell me that it’s not airworthy because I’m actually a designated engineering representative of the FAA and I’m telling you that it is. But it was really crazy how that went.
  12. The engine shop cut your engine life in half. But at least they saved 50$. but seriously I put this in writing and verify it before taking delivery. It’s that important.
  13. Well, you can’t get to it from the dipstick hole in the case because you have to make 160° turn, go thru the slots where the case halves come together and get past the crankshaft and then you have eight lifters and six cam lobes to view. You can’t really go up through the drain port where the oil comes out because of the same issue, you have these quarter inch wide slots that are on the center line of the case halves that you have to go through and then go around the crank and then bend back towards the middle of the case to see the cam lobes. You can however, pull a cylinder off and you can see all of them pretty easily, but that’s the only way I know of.
