Work on the nosewheel and wing fillets

Suomeksi

On Wednesday, May 31st, the Caravelle assembly team worked at Turku airport in windy weather, concentrating on smaller and less impressive, but nevertheless important details.

The assembly of the wing to fuselage fillets was continued. In the wing root there are several fillets, of different shapes and sizes, fastened with rivets and screws. The assembly team spent all day fitting these fillets into place, on top of the wing and below it. Fasteners, which had been drilled out in Arlanda had to be removed, holes were opened, and countersunk edges drilled. New fasteners were installed, screws with cup washers and pop rivets. Probably hundreds of pop rivets were used during the day. Unfortunately the bottleneck in the assembly work was that there was only one battery-driven pop rivet gun in use.

The nose landing gear has been retracted since Arlanda as the fuselage has been on supporters on the floor. Now an external hydraulic pump was connected to the actuating cylinder of the nose landing gear and using the emergency manual unlock mechanism the landing gear was extended. The nose was lifted a little with the jacks under the front fuselage and now the aircraft looks as if it is positioned on the nose wheels, although its weight is still on the jacks. In the future a support will be made for the nose landing gear to take the weight off the wheels.

During the day scaffolding was built around the tail for the assembly of the stabilizers. On Thursday, June 1st, the horizontal and vertical stabilizers will be transported from Pansio to the airport. The aim is to lift the horizontal stabilizer from the trailer on the Caravelle’s tail. It remains to be seen whether this is possible or not if the wind is as strong as it was today.

While the riveting of the wing fillets was going on at the airport, the Pansio hall was cleared. The hall contract ends on June 1st and all the parts, tools and accessories which are still there will be brought to the airport in a sea container. In the coming weeks the Pansio team will go on with the remaining painting and polishing work at the airport.
