Manual flaps really pay off in this situation, you can retract the remaining flap very fast!

completely away on final before you had time to get them back
up again I've repaired several handle brackets where they
tore at the tube intersection weld , this is caused by
putting the flaps down at speeds over 100 mph. I repaired
the black RV-4 of Charlie Duncans at around 800 hours, He
has a habit of putting them down at 100mph
Van, states the white arc is at 100 but I found that if you
stick the nose up for just a minute and bring the speed down
to 80 mph it's less pressure putting them down and a hole lot
better on the flaps from about 1990. The aircraft is well
[quote] maintained, frequently inspected and flown regularly; at least since
I've owned it (3 years now). With a little over 600 hours on the
airframe and engine, she's had her share of problems seen on this list:
cracks in rudder skins, etc. Nothing major.
Thursday, returning home from work, I dropped the flaps (electric)
on final, and felt myself holding right aileron to counteract a
constant roll to the left. It was bumpy, but it felt weird. I visually
scanned both wings, ( expecting to see a gremlin tearing skin off the
wing?) and noticed that the left flap appeared less extended than the
right. I centered the stick for a moment, thinking that the aileron
position might be creating an illusion. It still looked hinky. I
concentrated on the landing, which was trickier than normal due to the
roll correction and a crosswind.
Clear of the runway, I centered the stick and eyeballed the flap
position again. They looked normal now! I must be going nuts, I
thought.
Flaps up, taxi to hanger, scratch my head. Something told me to look
again, so I lowered the flaps, measured position each side, scratched
some more. I pulled up on the left flap with my hand, and it moved! A
lot! The more pressure applied, the farther it moved, as much as an
inch at the trailing edge.
I yanked out the seat and studied the weldment. It looked fine,
paint intact, clean, no obstructions stuck under it, bushings and
rod-ends secure. I pulled up on the arm connected to the left flap, and
it just had too much give! Then I noticed the slightest wrinkle in the
paint on the main tube, about 4" inboard from the left arm. I felt
underneath the tube near the wrinkle, and felt something sharp. Time to
remove the shirt & tie and Get on board. [url=http://us.rd.yahoo.com/evt=40791/*http://advision.webevents.yahoo.com/handraisers]You're invited[/url] to try the new Yahoo! Mail Beta.
