Situation update from Tikkakoski

Suomeksi

This blog post is based on the photo delivery from Tikkakoski by Jorma Laakkonen on 22 November 2025 and the Myrsky project update provided by Mika Rautasaari / Finnish Air Force Museum on 10 December 2025.

On the fuselage work is ongoing to produce the engine cowlings. After the drawing showing the latest development version of the so-called engine shroud plate was discovered in Tikkakoski, the task of manufacturing this plate was transferred from the Aviation Museum Society’s Tuesday Club Myrsky team to the Finnish Air Force Museum’s restoration team. The lower section of the shroud plate was made in Vantaa by the Myrsky team but, joining the lower and upper sections may still result in changes to the lower part as well.

The production of the engine cowlings has begun by making different wooden moulds for the engine cowlings and the air intake duct. Manufacturing of the sheet metal and stiffener parts for the engine cowlings, as well as the air intake duct itself, has also started, along with the fabrication of the flame tubes.

When the Myrsky’s wing was transferred to Tikkakoski, the undercarriage was fitted with patterned tyres used on the Vihuri. Now Dunlop tyres resembling the originals have been found for MY-14. These have previously been used on a Smolik training aircraft and it is likely that these tyres have fewer layers of fabric than the original Myrsky tyres. One of the tyres broke at the side during inflation and will be repaired, as the tyres are intended to be used only for exhibition purposes and will not be pressurised. Vihuri tyres will be fitted on when moving the aircraft.

The undercarriage struts have been painted with a mixture of Isotrol paint and aluminium powder, which is intended to imitate the original cadmium-plated surface.

The undercarriage and wheel well doors have been test-fitted, but further adjustment is still required before assembly.

The aileron mechanism has been repaired to ensure the ailerons can move along their correct path.

The elevators also need to be repaired, as for example one of the elevators was not straight. Furthermore, the counterweight of the other elevator was replaced with the correct type of weight.

These are the main points for now. This article is the response to many inquiries about what is happening behind the scenes in the Myrsky project. The aircraft will be completed in 2026, but the exact date is not yet known.
