I started by checking the fuses next to the battery tray first. I was startled when I moved a wire and it sparked! Obviously, the "hot" wire was loose in the cowling. This may not be the ultimate problem, but it is a problem. Unfortunately, I cannot really determine the appropriate terminal, and the maintenance manual is not very descriptive, and I don't like the idea of just touch a hot wire to terminals to find the right one. I really don't feel like having to drop the lower cowl to do the repair, either. The existing wires appear to be soldered on to the terminals. Is this an appropriate connection in a high vibration environment? Any helpful hints or tips would be appreciated.

Most of the fly-ins were Grummans (not one Mooney driver visited - hmmmph!), with a sprinkling of other airplanes, ultralights, powered parachutes, and a few RC models.

Although I've been flying a fair amount this year, I've barely put 50 hours on this plane since its last annual inspection, when the IA complied with the AD that requires inspecting this cable for wear. He also replaced all six pulleys at that time, which I learned when I picked up the airplane. I was quite upset that he did this without consulting with me, because he did not use the larger pulleys that are available now. He said I didn't need them. Well, you know that's where the cable broke. Remembering some comments when another pilot broke a rudder cable at the Blue Ash convention, I twisted these cables to look at the center. No obvious corrosion inside there, and no obvious rust anywhere. When this cable breaks, the rudder springs pull both pedals all the way forward. From that position, the brake pedal's travel is limited and steering is interesting, to say the very least. Another good reason to touch down as slowly as you can. You never know when an ordinary landing is going to turn into something special. ________________________________ Message 5 _____________________________________ Time: 10:21:35 AM PST US From: TeamGrumman@aol.com Subject: Re: TeamGrumman-List: Dome and Clock Fuse --> TeamGrumman-List message posted by: TeamGrumman@aol.com In a message dated 05/09/04 5:30:37 AM, mark.t.mueller@comcast.net writes: > I really don't feel like having to drop the lower cowl to do the repair, > either.

Look at my web site (if you have a 76-77 Cheetah or Tiger) and there is a wiring diagram for the plane. There is only one typo that I haven't fixed but it isn't in that area anyway. There is a wire that comes off of the battery relay and goes directly to the fuses. It splits and goes to both fuses. They were soldered from the facotry. Unfortunately, the wires are in a very hostile environment and get brittle and break. If it were mine, I'd replace all of the wiring AND fuses. Replace the wiring with approved 18-20 gauge wire and replace the fuses with Klixon circuit breakers. They mount from behind and won't have to be disconnected to remove them from the mounting. They also have screw attachments. Put shrink sleeving on the exposed ends.

I hope not. No planes were hurt either I hope. I haven't been back to Connecticutt since 99. My dad grew up in Southington. Know any Vogt's there? I could be related.

The cables in the AA1 seem to be a problem. Paul Fitzgerald had a 76 Tiger here in Lancaster, CA. He was doing an annual last year and found some frayed cables. During the replacement of the cables, he found a few bad pulleys as well. I always rotate the pulleys (during an annual or when I'm in the area) by hand and look at the wear pattern in the pulley. It lets me know if the pulley is moving or if the cable is sliding in the pulley.

This isn't a list where you have to worry about the content of the message you send. If it's interesting to you, chances are it's interesting to several others as well.

Nothing wrong with that, but don't you think that pull type breakers in the engine compartment is a bit of an overkill? The only advantage I see is you can easily remove the breakers when you want to remove the battery mounting tray for painting.
