Since the flaps didn't reach the lower limit, it's hard to see how the limit
switch could be the culprit, unless it stuck closed. Wouldn't the flap
switch itself be a more likely cause?

Could be but my guess would be the flap motor. Electrical motor has
overtemp switch. When they start to wear out they overheat during operation
- temp switch cuts off motor. Minutes later, it cools off enough to operate
again for a little while anyway.
I've had this happen on two different planes.

You are absolutely correct. =C2-I'd have to go over the wiring diagram to
see what the failure modes would be. =C2-The only thing that would stop th
e flaps from going down, WRT the limit switches, would be something jamming
the limit switch prior to the down limit. =C2-If the switch appears to be
OK, then it's something else. =C2-By-the-way, the switches fail open, not
closed. =C2-So if the switch failed, check to see if something jammed into
the switch. =C2-Not likely, but, you never know.
PS, you can find the wiring diagram for your plane on my web site. =C2-

it's in there.

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...
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 h
appened. 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

Could be the limit switch or maybe just a wire that came off the terminal at
the flap switch or at the limit switch.

I concur with Cliff. =C2-
Open up the back and take a look at all the hardware yourself. =C2-The wir
es to the switches are very difficult to get to. =C2-The switches are a pa
in in the ass too. =C2-Maybe Kevin will redesign the mechanism and move ev
erything toward the middle about 6 inches. =C2-It would sure make working
in there easier. =C2-
Find the down limit switch. =C2-Sometimes the lever that actuates the swit
ch is bent off center. =C2-Be very careful with it. =C2-If you can, have
someone try to actuate the flaps. =C2-
If everything looks good at the motor and switches, remove the right side of
the center console. =C2-Check the wires on the flap switch itself. =C2
-
By-the-way, for those of you out there with the AG5B: =C2-The flap limit s
witches are all wired backwards from the earlier planes. =C2-This works, b
ut, the power and grounds are all messed up. =C2-I have one customer with
a 2004 AG5B that had a squealing sound, once-in-a-while, when the flaps were
put down. =C2-I rewired it to match the AA5B wiring diagram and the squea
ling went away.
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-

I'd be flight testing but, it's been 105+ degrees and smoky. =C2-Visibilit
y here in Auburn has been down to 1/4 mile. =C2-Next week should be better
. =C2-Cooler anyway.

Hi Gary,
Hope all goes well with your flight testing. I'd like to do my annual around the
last week of September. Hopefully this works out for your schedule, although
I could do it any other time that month. Just let me know. Can't believe another
year has almost passed. Seems like only yesterday I was crawing under my
panel with your lube can. I have a few things I want to address, but I'll talk
to you about it later. At least I know I won't need a muffler! Thanks.
Bill
