Re: Europa-List: Re: Angle of Incidence on a Classic Taildragger Downunder
=0A =0A=0A=0AHi Guys,=0AI would like to make a few comments / observations,
not in any particular order, on some of the postings on here recently.=0AG
-KITS, originally had a set of Classic wings, built by a third party, where
the port wing had 1.5 degrees of washIN, not-evenly distributed along th
e wing, but mostly in the outboard panel. Wings rigged using the root area
as datum. It flew, as you would expect, one wing low.=0AAttempts to trim th
is out with aileron re rigging and flap drooping were unsuccessful,-so th
e port wing was re rigged, can't remember by how much in degrees, but the f
igure of .3'' down at the leading edge comes to mind.=0AWent much better af
ter that, with some stall strip juggling it stalled true, BUT spins in one
direction were frightening-[ as in change of underpants frightening !].
=0AG-KITS was then retro fitted with a new set of XS wings,[ the original G
-KITS-wings went on the then retired G-YURO which was lost from active se
rvice in a take off incident-when the Arplast prop decided, uncommanded,
to go into Beta.........]=0ASockets had been unbolted / sweated off, alloy
plates replaced and wing refitted as per Manual. Seatback spar bush re alig
ned with a hot, tapered-pin- ''pugler''. Warm the pin, shove it through
the seatback / wing spars and go for a coffee.=0AUV degradation.... the pa
int would have been AERODUR C100UVR, about as good as paints get, the regis
tration decals would have been Fascal vinyl, with a 7 year life... how old
is KITS now ?..... Quality- polyurathane paints live quite well in Miami
and Bahama marina's, unlike some of the ''unquality'' water thinned cr*p=0A
-=0AWing--incidence cock up.......do it correctly, NOW ! Sweat the so
ckets off and redo it. Make sure the wings are fully forward, by tieing the
spar tangs forward with rope, or chocking with wedges.=0A-If using a-d
igital level, MAKE SURE YOU READ IT FROM THE SAME DIRECTION [ LOOKING INBOA
RD AT IT ON THE PORT WING, AND OUTBOARD AT IT ON THE STARBOARD WING] I have
seen builders doing ''dry runs'' and looking inboard at the readout on bot
h wings, any error in the tool itself, or in fuselage levelling will be dou
bled. Tap the level to see which way the reading ''skips'', get the ''skip'
' the same on both wings. This will be as close a matters in the real world
.-=0AShore the wings in several places so no movement is possible during
the overnight Redux cure.=0A-=0AOsmosis.... people are confusing Osmosis
with Micro Blistering. What will be evident on a painted Epoxy surface is M
icro Blistering, where water has got between the paint and the substrate, u
sually as a result of covering a wet [ water] surface and letting it sweat
like a sauna, the moisture has gone through the paint skin and is trapped.
Leaving this out in- the sun will usually dry it out. Left uncovered is a
better option than covers. Micro Blisters are not a structural issue, mere
ly water sitting on top of the epoxy substrate.=0A-Cover a car with a non
breathing cover, left wet, the same Micro Blistering will occur over a ste
el substrate. =0AOsmosis [- in the GRP meaning of the word ]-is the rea
ction with chemicals in / on the glass fibres [ usually the PVA binder hold
ing the CSM together] and water, usually within- polyester-resin,-whi
ch turns to acid [ and will smell of vinegar if the bubble is-popped.]=0A
-=0AMy Inspector said ''that's the one with all the Mods''.......- work
ing from memory, there were 32 Mods incorporated into the XS Kit by 1996, s
ince then there have been 8 MANDATORY MODS, the rest have been upgrades. Pu
t this into perspective, the Slingsby Firefly has 1200 + mods, wonder how m
any mods apply to a C150 ?=0AThe tie bar was introduced to allow the Gross
weight to be raised to 1370 lbs, if anyone is happy to have the 1300 lb lim
it, the tie bar is not required [ nor is it required to change to the swive
lling rear sockets.]=0ABit of History, the original G-YURO front wing pins
were .75'' long, and there was no top hat stiffener from thigh support to d
oor sill. Pete Clark [bless him] was ''vigorously exploring the flight enve
lope'', and- pulled a ''bit'' of- G, and the front pin popped out of th
e socket and rode above said socket. Apart from the ''bang'' which scared t
he s**t out of Pete and Roger Bull [ who was riding shotgun], nothing else
happened, though it took some effort to de rig-the wing later.=0AA longer
front pin [ same length as the flap pin,] and the top hat stiffener cured
-that.-=0ARegarding Inspections, if the Inspector chosen for Permit Ren
ewals only ''knowledge'' of the Europa is ''that's the one with all the Mod
s'', he probably [ or more likely definitely] isn't the Inspector you need
to do the Permit, especially if you are not the builder of the aircraft.=0A
I once worked on a Europa that the current owner had just bought, with 5 ho
urs flight time since the previous Permit, that had been Inspected by an ''
old timer'' Inspector, and there were so many flight safety faults with it,
I had to ''dob in'' the Inspector to LaaLaaLand. Turns out he was an exper
t in-Austers and the like, but knew SFA about the-Europa. LAA didn't ta
ke any action as he had since retired from Inspecting.=0AComparing a C150 w
ith the Europa is pure folly, like comparing a Morris 1000 with- a Ford F
ocus ST ?=0AI have 1.4 hrs in a C150, time I am never going to get back....

first time is good. But also I dimly remember (from the days =0Aof the Eur
