When took on this
work we promised that the Tiger Moth should be able to taxi under
its own power when it left our workshop. This goal was achieved 19
August at Kjeller. Following a few engine adjustments Tiger Moth

Kjeller. A couple of runs along the runway with high tail made a
finale to the project.

is replicated as closely as possible to the paint scheme it wore
late April 1940.
we will trial install skis and prepare the airplane for a 330 km

war memorial collection (Dovre og Lesja krigsminnesamling).

This project has
been going on for many years, but finally we can se an end to it.
Four wings and the tailplanes are finished and ready for
installation. We have even trial installed the lower wings. The
engine is basically finished and temporary installed in the engine
mounts. Only a few nuts, gaskets and other minor details is missing
before the engine can be permanently bolted on. However, we
discovered unexpected problems when we started to install our engine
cowlings. We had the original front cowling and a set of worn-out
cowlings panels from various airworthy Tiger Moths. Surprisingly,
the Norwegian cowlings differs considerably from the British design.
We had to decide whether to go all British or keep the original
Norwegian front cowling and modify the British made panels. In order
to be as original as possible, we decided to do the latter. This
involves modifying three panels and make a side panel from scratch.

engine restoration has been in focus the last months. This is the
original Gipsy III engine which was installed in the airplane when
it crashed in April 1940. Luckily the engine was removed from the
wreckage by locals during the first summer and kept indoor ever
since. Although many details, amongst them the cylinder heads,
magnetos and the carburettor disappeared, the basic engine was in a
good condition when we started the restoration. The aim is to make
it runnable, although this will include the installation of some
Gipsy Major parts. As can be seen om the photos, the completion is
not that far away.

time since we last had an update. Although the progress on Tiger
Moth 145 has been slow, lots of work has been carried out in the
“Storch nest”. Oner reason for this slow progress has been the heavy
maintenance on Tiger Moth LN-MAX. Additionally, serious problems
with the starter on Storch LN-WNS has drained available time from
the Tiger Moth 145 project.

bits and pieces have steadily been added to the airframe. The most
welcome was several landing gear parts sent to us as a gift from
Aeroplane Company P/L in Tyabb in Australia! Combined with a few
original parts from Tiger Moth 145 we have managed to rebuild a
complete set minus rims and tires. Another significant addition is
the instrument panels. The only items remaining is the altimeter and
the compass. There were several variations between instrument panels
on Norwegian Tiger Moths. We have a few blueprints and photos and
believe we have made a representative panel. The plan is to install
all details inside the fuselage before we put on the fabric.

restoration is moving along nicely. Three wings are now structurally
complete. The lower R/H wing is fabric covered, stitched and taped.
The fabric is glued on the lower L/H wing and it is ready for
stitching. We decided to use modern Ceconite fabric because this
should last longer than any of us. A teacher at Dovre Handverksenter
(Hjerleid) is about to make new wing spars for the upper R/H wing.

the lower R/H wing is nearly ready for fabric cowering. Like the
first wing, this is assembled mainly by repaired original parts made
at Kjeller. We even had a complete aileron. The biggest challenge
was to reproduce the trailing edge near the fuselage. The trailing
edge curves slightly upwards on Tiger Moths made by DeHavilland
while it is straight at Tiger Moths made at Kjeller. The third wing,
the lower L/H wing is also nearly finished. For the fourth wing we
only have a couple of ribs left, so we might have to make several
new ones for this.

upper L/H wing is now complete and ready for fabric cowering. We
started out with two bad wing spars, a heap of broken ribs and a
number of worn-out metal fittings. It turned out that all except two
ribs was originally made at Kjeller. It was evident as most of them
was marked Kontrollert
(controlled) in addition to a date and a signature. Even the nails
and screws are recovered from original Kjeller parts. We think this
became an exceptionally good documentation of a Kjeller built wing.

included seats, flight controls, the extra fuel tank and the wind

complete disassemble, we started final painting and installation of
parts. In order to finish installation of the upper wooden
construction, the tail and forward fuselage sections were bolted
together properly for the first time. We have also installed the

all details completed this summer are made from scratch. It is
sometimes tricky to find out exactly how our Tiger Moth was back in
1940. We have a few drawings but we are also dependent on making
measurements at the Tiger Moths based at Kjeller. The problem is
that they all have become a bit different during the years, and that
there was a significant difference between British models and the
models licence built at Kjeller.

The Tiger Moth
has been on the back burner for several years. The Storch has got
most attention, but Eivind Svenningsen has done some Tiger Moth work
in-between. Notably, most of the flight controls in the cockpit
nears completion. Lots of parts has been finished and made ready for
final installation. The last component that has received attention
is the oil tank. It was badly crunched in an accident, but Eivind
has managed to make it oil tight and look right. The Storch is a few
months from being completed. Then the Tiger Moth will get full
attention from the whole team.

More working hours has been spent on the workshop this summer than on restoring airplanes. 90 m² of a previously “cold” section of the building has got the same treatment as the rest of the workshop. A part of this area has become the carpenter’s workshop and the Tiger Moth airframe has already moved inn. It is about time to get started with the cockpit area. The Gipsy III engine has also got some attention. During disassembly it was found to be in excellent condition with no wear. The plan is to find missing parts and run the engine.
