  1. I remember reading somewhere (but now of course can't find it) that Saturn V launches were, at least from the astronauts' perspective, very gentle. The first few seconds it was impossible for them to know (at least by feel) that they'd even left the ground. Ah, found it: “The Saturn V had a much lower thrust-to-weight ratio than Titan II GLV, the launch system used by Project Gemini, NASA's second human spaceflight program. Richard F. Gordon, Jr. described Saturn V as "an old man's ride", with "a lot more shake-rattle-and-roll" but milder thrust. Buzz Aldrin and other Apollo 11 astronauts agreed that unlike Titan, they could not tell when Saturn V liftoff occurred except from instruments.” https://en.wikipedia.org/wiki/Saturn_V#Titan_II
  2. $1,072.60 for the crank case including freight to/from SoCal. $267.27 for the accessory case including freight. Sent from my iPad using Tapatalk
  3. I learned more last night. “Bob” was operating (for decades) out of a T hangar on the non-commercial side. He had the fuselage of an old Cessna hanging from the rafters to “satisfy” the “used primarily for storage of an airworthy aircraft” requirement. City found out about it, and is evicting him.

  5. After months of no communication from "Bob," I hear from our A&P (not Bob) that Bob's retiring and not going to finish my engine overhaul (was torn apart and farmed out to DivCo (we have the cases back) and Aircraft Specialties (invoices are paid, work done, parts - all new cylinders, crank/cam shaft, etc - still at their facility). The highly recommended local shop (Tim's at Long Beach) doesn't want to jump in mid-process. Anyone know a shop that can put this thing back together? Preferably on the west coast.

  6. They're quoting $1275 + shipping for the McCauley (overhauled, I'm assuming, no core exchange). Think that's the route I'll go.
  7. How so? Savvy and I were pouring over the logs from the 830 and none of us caught the intake lobes issue; I had an A&P run a valve lift check and that caught it. Sent from my iPhone using Tapatalk
  8. Is it a bolt-on replacement? I'd just as soon not grind parts. I remember reading about folks' positive experiences with the PCU5000 and now kinda wish I'd pulled the trigger back when this first came up; they've gone up in price a lot (IIRC they were about $1700 in 2019, and are about $2700 now(!)). (I'm not super concerned about the overhaul cost of the PCU; what's TBO on a governor?) Sent from my iPhone using Tapatalk
  9. TrueSpeed in VNY is describing my old Garwin as a boat anchor; they'll overhaul it but the last one they did had the same problem I was having (fine on the ground and in level flight, slipped when you'd change pitch). I was going to IRAN it anyway, but with the metal in the filter following the intake lobes spalling, it needs an overhaul anyway. So for about $1660 (incl tax) they can overhaul the Garwin, for $1855 I can put on a McCauley they've overhauled (or factory new, a bit over $2,000), or the PCU5000 which is more yet and the shop doesn't recommend (expensive overhauls when the time comes; there's a stud that wears out that can't be field serviced and has to go back to the factory?). WWYD? I'm tempted to go with the overhauled McCauley (this whole thing is already more than expected...). Sent from my iPhone using Tapatalk
  10. Which would be better, two EIS at 20° or one EIS at 25° (or variable, but wasn't there a report here that the variable timing was not compatible with high altitude departures?) and one needing IRAN every 500 hours old school magneto?
  11. Just saw this: https://www.aircraftspruce.com/catalog/eppages/lycoming_eis.php Made by SureFly. Fixed timing (vs. SureFly's variable). About the same price. Pros/cons? (I'm about to pull the trigger on a freshly overhauled mag, and an EIS, for the IO-360-A1A in an F.)
  12. All of those are VFR transition routes. If you're IFR you don't need to worry about a Bravo clearance Sent from my iPhone using Tapatalk
  13. According to Mike Busch last night (EAA WINGS seminar on annual inspections, focusing on a Lycoming O-320 that wasn't making minimum static RPM and had this exact issue), oil analysis won't catch the intake lobe wearing down like that: The pieces come off too quickly, and are too large to get absorbed into the oil. Any indication would be in the filter. Anecdotally, that was my experience (IO-360-A1A). 3RM has been on oil analysis consistently since 2008, including right before I had a valve lift check that caught that intake lobes were worn too far. There was no indication of it in the trends. My iron (29) was slightly above universal averages (20), but no mention of that in the Blackstone write-up, for an oil change in March, 50 hours before the engine was yanked for overhaul, and with 43 hours since the last oil change (Blackstone did note in an earlier oil analysis that my 59‡ hour oil analysis showed 52, but also noted "universal averages are taken after ~30 hours of oil use [and considering] this interval was about twice as long as that, some extra iron (from steel) doesn't look troublesome as that metal tends to track with use." (They recommended "follow up in 40 hours for an update.") ‡ Was supposed to get an oil change before launching on a trip to St. Louis but my A&P was chasing other gremlins and didn't get to it. Was going to get it changed in St. Louis but the A&P I found there likewise fell down a different rabbit hole and ran out of time. :/
  14. Thanks! Do I need the $15 "Manufacturer C of C" ("Traceability Paperwork (if available)")? Edit: Sounds like probably no (but at $15 it's cheaper than the gas I'll burn to pick everything up, so why not...) https://www.skylinkintl.com/blog/traceability101 Sent from my iPhone using Tapatalk
  15. Where is that in part 91? (Hint: it’s not.) there’s a requirement under part 23 (though our planes were certified under CAR 3...)
  16. Just making sure - Mooney M20F, 1969, no impulse couplers, correct? My interaction with the SureFly folks: Yes, Remove the SOS - you won’t need it. Depends on which mag you are replacing. If it has an impulse coupler then use SIM4P
  17. Older ones especially; starting with all F models and, in '69, the rest, they raised the top of the green arc.
  18. 8,000' AGL? So, departing Flagstaff, I'd want to be at ~16,000' MSL?
  19. It hasn't, at least not under the AIP, and nothing within the last 20 years.
  20. We're working on it. Interestingly, at TOA this has nothing to do with making the airport self-sustaining (a common argument); TOA generates a net profit of about $10M/year, which goes back to the City's general fund. (Yes, they can do that, at least as it appears right now; there are no grant assurance obligations in place, etc).
  21. I flew a couple of PnP missions in my E. Crates were a mixed bag, sometimes they had them, often times they did not. Only a couple of small crates would fit in the cargo area / rear seat of the E, and IMHO it's not a practical platform for most PnP missions. (Largest dog I ever transported was a Mastiff puppy, from SMO to AVQ; fortunately, he was a mellow lovebug who just slept in the back seat.) The F, especially with removable seatbacks, is much more capable. I fly large dogs all the time, often multiples. I have my own big softside crate that takes up the entire back, and it's easiest for me to just use that (I'll bring their crate along, collapsed / disassembled, if they have one). I use the sof-krate n2 crate for the F with no rear seats (dimensions: 42"L x 28"W x 31"H); I've also used a Precision Pet Products 3000 3501-35013 (30L x 20W x 19H). If you're okay without a crate, I had my 65 lbs Labrador and my 45 lbs street stray in the back seat with a long weekend of luggage in the back of an E and it was "okay-ish" (SMO to HCR), but the dogs were mostly just tolerating being in those conditions.
  22. If I own my own twin, it'll be a kit, and it'll be running COTS turbodiesels I can just replace for $5K or so apiece... The Velocity folks are prototyping a Twin with derated (~280 HP / side) automotive diesels; they're also flying one built around DeltaHawk powerplants. At diesel engine fuel consumption rates (two DeltaHawks sip about what a single IO-360-A1A does in a Mooney), the reduced hassles and cost of being able to work on my own airframe, non-certified avionics, and commodity engines, I'm not seeing big downsides to a twin - especially one as relatively docile as the V-Twin. TBD...
  23. Is almost relaxing, when you have another one turning. Passed my PP-AMEL checkride (in a Duchess) yesterday. Plans TBD, but will definitely be getting the Mooney back in the air. (May keep it, but also take a partnership interest in a 340. Developing... (Eventually want to build a Velocity Twin with diesel engines.))
  24. I did an 830 a couple of years ago because it already had a 700 that was fritzing (though it turned out it wasn't the 700 that was the issue; it was a bad factory CHT probe) and it was a cheap, pin-compatible, upgrade to the 730 ... But then of course, "as long as we're in there," the FS-450 was removed, the -730 got sensors added to make it an 830... I should have just gone 900/930 and been done with it. Pennywise...
