I was able to drop my flaps 2/3rds on base leg. After I turned final, I depressed the switch to drop the last 1/3rd, but nothing happened. I cycled the switch a couple times, but the flaps would not come down any further. I flipped the switch up, and the flaps started to retract, so I immediately stopped and tried to depress the switch in the down position again, but the flaps would still not come down. I tried a couple times, but no luck. So I kept the flaps where they were until after landing. The flaps retracted fine after landing, but would not come back down on the ground. A local guy believes it to be a problem with the lower limit switch. This is the second time in the last six months this has happened, and the last time the local guy said the same thing, but obviously he did not fix the root cause of the problem. WSY??? What's the most likely culprit? Where should I look first? Thanks, Mark Tiger N1533R ________________________________ Message 2 _____________________________________ Time: 06:13:47 AM PST US From: "flyv35b" Subject: Re: TeamGrumman-List: Flaps Malf Could be the limit switch or maybe just a wire that came off the terminal at the flap switch or at the limit switch.

Also, the fuel tank sending units on the AG5B have their own ground. =C2-U nfortunately, the end attached to the rib corrodes and then the gauge won't work. =C2-I installed a separate ground from the sending units to the gaug es and now the gauges work. =C2- =C2- -----Original Message----- From: Mark Thomas Mueller Sent: Wed,=2 09 Jul 2008 3:06 am Subject: TeamGrumman-List: Flaps Malf As I turned base to final on my last leg home from Michigan to Virginia for the 4th of July weekend, my flaps malfunctioned in a very interesting way...
