Annual Chapter 724 Banquet

Donít forget, the annual banquet is later this week. As usual, itís the Friday before Sun Ďn Fun, on April 12. The banquet this year moves to the Cocoa Beach Holiday Inn. Banquet ticket price is $15, which includes a prime rib or fish dinner. Happy Hour starts at 6 p.m., although you can come as early as 5, and supper starts at 7 p.m.

Our guest speaker has been finalized and will be "The Voice of EAA" at Oshkosh and Lakeland, Roscoe Morton. John Murphy will fly over to Lakeland to pick up Roscoe, and will fly him back the same evening after the banquet. No beer for John!

Eric Kinnerd reports that the chapter has received many door prizes from many vendors for the banquet, including a stereo intercom with wiring harness, kneeboards, flashlights, videotapes, headset bags, tee shirts, and gift certificates, and gifts are still coming in. Eric says the deadline for ticket purchase is April 9! Call him for tickets and information at 631-3264.



Marchís Meeting

At the March Chapter 724 meeting, our officers determined that we had 87 paid-up members, and 10 not-paid-up members. Címon guys, itís only $12 per year.

John Murphy did a "show and tell" with the Bendix pressure carburetor from his Bonanza. This old veteran is wearing out and getting hard to maintain (the carburetor, not John!). Rather than pay extremely high prices to get them repaired, some owners are opting to install Bendix RSA injection systems on their Bonanzas, as John is doing. The STC for doing this has been around since the Ď60ís.



Cheap 100LL

Bob Gluie, new operator of Merritt Island Air Service, is offering 100LL avgas to those pilots who operate out of Merritt Island Airport for only $1.79 per gallon.



Venturis Again

From Cub Clues #68, May/June 1995

An additional problem with a one-piece venturi in MP35AP carb -- this info appeared in a column by Bill Rhodes, editor of the Cessna 120/140 newsletter (Aug. 94, pg. 3). It seems that the one-piece venturi could have changed some parameters.

The newest complaint is increased fuel burn, over ten gallons per hour in one case, and an increase in carburetor icing with the uprated carburetor. Precision admits to sporadic problems in the field and is presently field testing a new fuel nozzle. According to Precision some of their carburetors are sensitive to the airflow in the carb heat box and the venturi change was just enough to cause problems. The redesigned nozzle (called a "pepperbox" type) is supposed to correct the airflow problems in those carburetors. A member with problems with the one-piece venturi should contact Precision (try Randy Jensen from Precision Airmotive 702/699-5555) and find out when the nozzle will be available. One note: The Marvel Schebler is on the continental O-200 and most Lycoming engines. there are a few out there on the A-65, C-85 and C-90ís; however, most of them came equipped with the Bendix NAS3A1. there is a Precision Service Bulletin available from EAA Information Services, telephone 414/426-4821.

Elastic Stop Nuts and Loctite

From EAA Technical Counselor News, Summer 1995

We had a question on the use of Loctite on elastic stop nuts; I contacted the Loctite Corporation in Cincinnati. Their answer was that Loctite is compatible with phenolic thermal set polyester and nylon elastic stop nuts and should be no problem for the average user of stop nuts. It is like using both a belt and suspenders when you use elastic stop nuts and Loctite, but it doesnít hurt to be conservative.



Starter Solenoid Hang Up?

from Chuck Downing


Have you ever had a starter solenoid fail to release after the engine has started? It causes the starter to continue to turn while the engine is running. This is difficult to detect and can damage to the starter and ring gear. Because of the gearing difference between the starter and the ring gear, a running engine drives a stuck starter at an extremely high r.p.m. By adding an easily connected warning light on the panel, you can be alerted when the solenoid does not release and can stop the engine to investigate.

Connect a wire to the output side (starter side) of the starter solenoid and run it to the panel mounted indicator light. Ground the other side of the indicator light. The light will go on during engine start and should go off when the start switch or button is released. If the light does not go off, it indicates that the starting solenoid did not release.



Wood Prop Failures


Ben Owen, Executive Director of the EAAís Technical Counselor Program, is collecting information on propeller failures on homebuilts. If you hear of any propeller failures on homebuilts, he asks that you contact him with details and, if possible, a photograph at EAA Technical Counselor News, P. O. Box 3086, Oshkosh, WI 54903-3086.
