The Supreme Court ruled that because "it is doubtful that telephone users in general have any expectation of privacy regarding the numbers they dial" that it was ok for the police to record these numbers. So, according to the Supreme Court, the more the average person gives up their constitutional rights, the more all of our rights are eroded. I would be worried about writing too much in the aircraft logbook since if this kind of twisted logic is used by the FAA during a ramp check, then eventually, if lots of people start putting unnecessary things in their logbook, you might fail a ramp check because you did only what was legally required. > Everyone says we failed to connect the dots, but fail to see that we need > the dots to connect first. That's a can of worms! From what I've read, there were FBI agents in at least two parts of the country that were shouting at HQ that they had potential terrorists getting flight training, but the HQ people didn't listen. Seems like we had more than just "dots" to connect, we had stick men, but still didn't get the picture. I'm not sure more erosion of our liberty is the answer. -- Mickey Coggins http://www.rv8.ch/ #82007 finishing do not archive ________________________________ Message 2 _____________________________________ Time: 04:16:54 AM PST US From: "Dana Overall" Subject: RV-List: Barry Mounts and torque --> RV-List message posted by: "Dana Overall" I bought four new barry mounts locally and have a couple question.

I am sure the guys at Superior check that one so important they know what the sentiment is out here. Last time I talked to them about these failures, they assured me "It's never happened in flight." Cold comfort. They also said they're working on a replacement, but not free to present owners unless you "have a problem". These folks need to step up, communicate with their customers, and schedule free replacements when available. Mine is still in the garage, but 90/90, so I hope they get off their duff. My .10.

I did my first long cross-country from Oakland to there, in a C-152. I wound up parked next to a Nigerean Herc, as I recall, and my view to the tower was blocked by a 747. Their progressive taxi instructions to me on departure started "Taxi forward until we can see you..." As I went to the ramp to arrange for service (I had lost my vacuum pump about 10 miles out), a NASA T-28 taxied up and the two pilots leapt out, giving instructions to "refuel and park it, please"; leaving a novice pilot (me) starry-eyed that they could use the FBO as a valet and the T-28 for a weekend commute to Vegas. There's always something interesting there, in all sizes and shapes. While I, too, am not interested in the shows or gambling, I do like to visit some of the theme stores and casinos. The NASCAR attraction is interesting, and I like to spend a little time at Margaritaville and the Harley-Davidson caf. These are my preferences; what I'm really suggesting is that you stroll the row and see what catches your eye. The Venetian is an example of a place that has more than the usual casino fare; there's shops and restaurants. You might also want to take the tour flights. Anyway, good luck and have a good time.

Most RV guys I know do ONE tire 'rotation' for the life of the tire. If you wait until the insides of the tires are just about done before you rotate, you should only have to do it once, and it will significantly lengthen the life of your tires. My 'AeroTrainers' lasted a little over 300 hrs, and with one 'rotation', a set of "Condors" lasted 600 hrs on my RV-6 (the grooves were still just visible, no cording).

The first is at the top of the compression stroke. The second is at the top of the exhaust stroke and the opening of the intake valve. If the spark hits the fuel/air mixture at this point, a back fire occurs towards the carb or throttlebody and the ryton sump cannot contain the explosive condition, therefore, it disintegrates.

I believe that Das Fed will tell you that an AD has never been issued on a homebuilt. Yet. Remember the uproar just a few weeks ago over Van issuing a 'mandatory' service bulletin? Do you really want something like that issued by the Feds with the force of law? I'm not questioning the wisdom of carrying out some particular safety-related SB. I'm just saying that I don't want the Gummint treating my homebuilt like a factory plane. Making logbook entries that talk about complying with AD's are starting the slide down that slippery slope. (BTW, the dots were visible and connected; the people at the top just refused to listen, just like they refused to listen to the CIA & military prior to the current Iraq situation.)

Thomason" Subject: RV-List: Ryton Sumps --> RV-List message posted by: "Mannan J. Thomason" "I don't believe this" Ron: Here's my two cents. The forward facing sump means that the engine is fuel injected. This = condition happens when the boost pump is left on too long with the = mixture in the rich, or other than idle cut off position. Raw fuel is = sent thru the injector nozzles into the intake area ahead of the valve = and drains down the intake tubes into the air plenun below the oil sump. What happens next is that the electronic spark system which fires on two = of the four strokes of the combustion cycle, (unlike conventional ignition systems which fires only one time in the = four cycle circuit), fires when there is an open path to the plenum, = intake valve slightly open. If conditions are right, a flame front = travels down the intake tube into the plenum igniting an explosion. It doesn't take much. I have seen a demonstration put on by the local = firefighters where one drop of gasoline created an ear-spliting bang. You've seen, or at least heard of backfires on engine starts with = regular mags too, i'm sure. Pretty much the same thing happening there = too. Probably not likely to happen in flight, but you couldn't give me one of = those things.

Thanks for = pointing me in the right direction Gary. Here's the deal: If you want a "cold air sump", there seems to be 3 choices- Ryton sump by Superior Magnesium sump by ECI Barrett Precision cold air sump All the other metal sumps out there- Aerosport Power Aero Engines Superflite Are all copies of the Lycoming cast aluminum sump (not cold air sumps) The Ryton sump (by Superior Engines) we've discussed before here, it = costs 1000 to 1300 dollars and will break when used with a wasted spark = electronic ignition system...if not sooner, then later. You might not = know it's broken unless you inspect it closely like I did. Superior = does not see the magnitude of the problem of the sumps it has in the = field, but is currently in a "redesign" of the Ryton sump to address the = wasted spark ignition issue. The new sump is expected out by October. = Based on other new product announcements, I wouldn't look for it a day = sooner. The magnesium sump by ECI is just now becoming available and costs about = $2400 including the tubes. There are two of them out there on aircraft = so far. If you want to be #3, they should be ready to ship on May 22. = I was told I'd have to fab a support bracket for the Bendix or AFP servo = because that was "too much weight" out there for the induction portion = of the sump to hold unsupported. That bothered me. The flange for = mounting the fuel servo is also forward from where the Ryton sump flange = is, which will mean more extensive alteration of the air snorkel to get = it to fit. I don't have the information on the Barrett Cold Sump system, but it is = the most expensive of the three. I'll post that here when I find it. I guess that's it... My choice will be the Superflight sump, when it's available in a few = weeks. It's a clone of the Lycoming forward facing sump, so it's not a = "cold air sump". I have made peace with that and decided if I get a = sump that WON'T BREAK, that will be more important than a few more = horsepower. All these clones of the Lycoming forward facing sump are = priced about the same at $2200. I sure think there's a market out there for a well made cold air = induction system...but I don't think there's a good one at a reasonable = price that's available yet. For those of you who are running Ryton sumps, I encourage you to inspect = them very closely and very regularly. Like every time you fly. Two of = these sumps that have broken here have actually broken into pieces that = fell out onto the ground below the aircraft. The others have just = cracked. In the case of my sump, the engine still ran fine with the = cracked sump. Had we had the engine cowled, I would have had no reason = to uncowl it to inspect it before going flying. Had the lower part of = the sump (where the fuel servo mounts) broken off in flight, I am sure = it would have ruined my day. bob rv7a last few things plus a new induction system
