The Storch flew
for the first time 7 October 2017. LN-WNS (Warbirds of Norway
Storch) took off from the historic Kjeller airfield almost exactly
10 years after it arrived in the workshop at Fetsund in 2007.
Following 9,251 working hours it is difficult to explain the
excitement when I taxied out for the first take off and the feeling
of happiness when I landed after the 30 minutes flight. It flew
nearly perfect. All that was needed was to adjust a tendency to turn
left, hands off, adjust the elevator trim travel and clean a fouled
spark plug. Further, the variometer indicated 10 m/s descend while
flying level – obviously wrong. Nothing was too serious to prevent
another flight the same day. The Storch has now flown perfectly
another three hours with stabile engine indications. An oil filter
inspection confirms that nothing wrong happens internally in the

engine has been successfully ground run for five hours. We prepared
the Storch by filling 200 litres fuel in the wing fuel tanks and a
couple of litres of fuel in the separate primer fuel tank. A few
leaks were fixed. Further, we serviced brake fluid and filled engine
oil in the oil tank. A few days later Clemens Rüb from LTB Dirk
Bende GmbH in Germany came and did a few checks. Then we removed a
spark plug from each cylinder and primed the engine with oil, first
with an external pump, then by turning the engine by the starter.
18 September came the most exciting moment during the whole
restoration project. Would the engine start? Would the fuel pump
deliver? Would the magnetos make sparks? What about the oil
pressure? The engine started reluctantly, but ran happily the first
10 minutes. To my great relief, Clemens gave thumbs up when he shut
it down. I could not wait but touch the engine – for the first time
hot! A slight adjustment of the idle mixture and idle speed
was all that was needed. The next 4 hours and 50 minutes the engine
ran without a hitch. We finished off day two with checking oil
filters and changing engine oil.

The Storch was
moved to the hangar at Kjeller during the evening of 6 June 2017. It
was quite an undertaking with a big flatbed trailer. It was late
night before all parts and boxes were safely offloaded in the
hangar. Laid out it looked like a big Airfix model kit. Instead of
glue, the use of numerous bolts, castle nuts and cotter pins has
been the preferred method for assembly. Gradually, systems are
completed and function checks, leak checks and adjustments are
today’s tasks. We experience many smiles and a few disappointments,
but nothing that can’t be fixed. This is definitely fun!

is hopefully the last update from the workshop. Next update will
most probably be from the hangar during final assembly. The cowlings
are near completed. Just finishing details remain. For years I have
been looking forward to paint the Adler-Emblem on the cowling. Now
it’s time! New seat
belts have been manufactured and new tires and tubes are installed

still the main focus. The front cowling has caused all sorts of
trouble, but finally its installed and painted Hellblau on the
underside. The pre-formed skin for the R/H side cowling did not fit
at all. First we had to make a wooden plug and beat it to correct
form. Then we had to construct a roll forming machine to make the
internal doubler profiles for the cowling. Parallel to this we
started to make the heat shields positioned between the carburettor
and exhaust system. To make this we have to master the art of
forming parts with the English wheel. The learning curve is steep!

The cowling seems to
be the most challenging part of the restoration project. This is
probably no surprise to people used to restore aircraft. We are lucky
enough to have three original cowling details in good condition (top,
L/H side and bottom) but there are much more to it. The cowling on the
Storch is of “shrink fit” and do not accept the slightest deviation.
Two millimetres out of position one place can lead to a 5 millimetre
gap another place. The challenge is to find good references and adjust
accordingly. Can you trust original parts or is it the newly made
parts that cause the problem is a frequent asked question. I wish we
had a few more original blueprints of the cowling

So far the list of remaining work tasks has been too long to put on paper. Now, I have started to make a list of remaining to-do items. We have to make a plan for how to finish each task. Many tasks have been delayed because we didn’t know exactly how to do it or because we were missing parts. We know that the Storch don’t fly before all items are finished. The last flap, the landing gear, brakes, cowlings and the fuel priming system has been in focus lately.
The missing R/H flap (see News 3 June 2015) has arrived and has been repaired. Time to put on the fabric.
