Normally I do start my Piper at full throttle to evitate any kind of problems during the start.
That's very safe for the plane but it just doesn't look scale when you start like that. So after
years of starts at full throttle I wanted to start her slowly. Not being used to that procedure
and facing the end of the runway I pulled the elevator to hard and suddenly had her torquing
some feet over ground.
The motor is strong enough to torque and so for some seconds I gave full throttle but didn't
manage to stabilize her and so - in a moment when she was only a few feet over ground - I
pulled the throttle back totally.
My PIPER "landed" on the tip of her left wing and thenshe harshlytouched ground with the
tail wheel and then forwards on her propeller. So the left wing
, the tail wheel
were the parts that were damaged.
Rebuilding the left wing
The first we did was to remove the plastic sheet. The first diagnose then was that the damages
looked much worse than what it would actually take to repare them and so we optimistically
scheduled an afternoon's workto fix it.
First we repaired the fins that were broken without any material lacking. Wepulled them back
into their original position and joined them with superglue. For that we used a hollow needle
with the superglue bottle; that way we can allocate the superglue very precisely and we can
inject superglue into the woods as well. Inner healing . . .
Then we looked after the wing ear which had suffered most through the crash.
From ply wood (2mm) we made a reinforcement . . .
. . . adjusted . . .
. . . and then glued it.
Then the badly injured binding piece (holm) got an additional reinforcement.
This building lot was then injected with superglue.
So now the wing was fully repaired and just lacked the plastic sheets from ORACOVER to be ironed on.
That's the advantage of wood structures - even seemingly big damages can be repaired quite easily.
Here's a close look on the repaired wing:
As soon as I find the time I'll post the pictures of the next steps we took . . .
