Last-minute rush in Pansio

Maanantai 29.5.2023 - Erja Reinikainen

Suomeksi

The transportation of the Caravelle’s fuselage is approaching and the Pansio team members have been busy all weekend, completing the last tasks on the fuselage. The fuselage will be lifted on a trailer on Monday evening, May 29th, and transported to the airport during the night.

The last tasks included the stencil stickers, which were fastened on the fuselage for painting the texts and logos according to the Finnair paint scheme. The stencils came from the print cut into individual text sheets and the largest Finnair texts divided into several parts. The letters and logos which will be painted were picked away from the sheets – i.e. there are holes in the areas which are painted. When this had been done, an adhesive foil was placed on the stickers to hold the letters in shape when the stickers are fastened on the aircraft. The stickers used as stencils are placed carefully on the fuselage and the texts, logos and registration are painted with a roller, following the holes in the stencils. When the paint has dried, the stencils are removed.

The stencil stickers for painting Finnair and OH-LEA, which are the largest and most difficult stickers to handle, were fastened on both sides of the fuselage on Friday, May 26th. The stencils stayed well in place when the adhesive foil was removed, and the texts have been painted. Some of the stencils have already been removed, some of the texts are still drying.

During the weekend the blue stripe on the window line was painted once more. The blue paint is drying and the preparations for transporting the fuselage are on the way.  

Caravelle's fuselage is painted

While the assembly team was working at the airport with the wing junction, the upper part of the Caravelle’s fuselage was being painted white in the port hall in Pansio. The spray-painting was done by a contractor (Maalausliike T. Nikander). A layer of white paint was sprayed on the fuselage surface on two consecutive days, so two layers. Finally a protective layer of lacquer was sprayed on the painted surface.

The Pansio team found spray-painting to be a challenging task for amateurs and decided to hire a professional to do the work. The project schedule doesn’t allow any practise rounds at this point. The spray-painted area looks good, thanks to the professional.

Actually we ran short of time with the painting work because the spring was very cold, the temperature in the unheated hall remained low for so long that the painting couldn’t be started in the planned schedule.

When the paint and lacquer on the fuselage have dried, the protecting plastic can be removed from the window line and the stencil stickers can be fastened on the fuselage for painting the airline and aircraft type texts.

At the end of May the lease of the port hall in Pansio will terminate, and during the winter all Caravelle’s restoration, painting and assembly work has been scheduled to keep this deadline. The assembly phase started on Monday, May 22nd, when the assembly team (6 people) and an experienced aircraft polisher came to help the hard-working painters and polishers in Pansio.

A lot happened in the hall in just half a day, when preparations were made for the transportation, painting, and assembly, which were at hand. The list of completed work is long: The lower part of the aircraft’s fuselage on the left side was polished, mainly below the wing area. A large area of shiny polished surface was completed. The ready painted and polished surfaces of the fuselage were covered with thin plastic to protect them from the spray painting of the upper fuselage, which will begin on the following day. The remaining fasteners of the wing junction were cleaned. The stabilizers, which have been painted and polished, were covered with tarpaulins. Aviation Museum Society Finland banner was fastened on one wing for the transportation as a commercial. The sea container, which has been used as a storage in the hall, was emptied. All essential aircraft parts, tools, fasteners, assembly accessories, etc. which are needed in the assembly work, were loaded into another sea container, parked outside the hall. Only the tools, paint, and stencil stickers, which are needed in the painting and polishing work during the next ten days were left in Pansio.

The assembly team spent part of the afternoon on the aircraft’s future location at Turku airport, measuring and planning how to make sure the wings are in the correct position and can be joined.

In the afternoon the sea container was packed and ready to be taken to the Caravelle’s future location at the airport. Moving the container on the trailer was not an easy task, but eventually the chains were in the correct position and the container was on the trailer. The truck carried also a couple of passenger stairs and two large jacks.

Loading the wings on the Ahola Special Transport trailers went well, the same procedure had been done in August 2022 when the aircraft was brought from Arlanda. The bridge cranes in the hall were used to lift up the wings, one at a time, then the trailer was reversed under the wing. When the position of the wing had been checked the wing was lowered on its supports on the trailer. The two trailers were taken to Turku airport before midnight.

In Pansio the hall was almost empty now and it is really strange that the hectic final push is almost over. The top part of the fuselage will be painted during this week and the stabilizers are waiting to be transported at the end of May.

On Tuesday, May 23rd, the wing assembly work began at Turku airport. In the morning two mobile cranes were on site bright and early. Before the wings were moved, the aircraft’s future position was measured carefully and marked on the concrete slabs, which had been dug into the ground. The left wing was lifted from the trailer. Finding the correct position required some work and patience from the crane crew and the assembly team members who were measuring and operating the jack. Finally the wing was lowered on the ground, its weight resting on the support under the landing gear, on a wing jack and on two wing supports. The right wing was aligned into place, inch by inch, using the two cranes. The wing junction brackets met each other, and they were secured using the assembly pins which had been made to assist in the aligning. When some final adjustments had been made on the wing position, the wing junction expansion pins could be installed, and the wing lowered on its supports. By mid-day all expansion pins were in place and the assembly team could sigh with relief: everything had gone far better than expected.

The wing junction’s canted brace struts were installed into place, then all tools and assembly accessories were collected into the sea container and the aircraft was surrounded with warning tape. The assembly will be continued next week when the fuselage has been painted and it will be transported from Pansio and lifted on the wing.

Several blogs have been written about the Caravelle III aircraft which is under restoration in Pansio, about its history and the progressing of the work. Without enthusiastic volunteers there wouldn’t be any activity, so it is time to talk about the people behind this project. This blog introduces an overview of the tasks which are needed before the aircraft is ready for display. I hope to continue with some personal interviews in the following blogs.

In the early phases of the project Janne Salonen, the chairman of Aviation Museum Society Finland had a key role. He has good connections to Jan Forsgren, who is a member in the voluntary organisation Arlanda Aviation Museum’s Friends (Arlanda Flygsamlingars Vänner). In spring 2020 Jan informed Janne that the owners of the Arlanda Aviation Museum, the representatives of Swedish National Maritime and Transport Museums, had decided to give up the Caravelle. The first assessments on bringing the aircraft to Finland were carried out by the board of Aviation Museum Society Finland. Also the official decision on launching this project was made by the board.

The seven members of the board have supported and promoted the Caravelle project all along, without reserve. The project outlines and the major acquisition decisions have been made by the board. The rental agreement of the Pansio port hall and the final display site at Turku airport have been negotiated by the chairman and the board. Also the details including major costs, such as the transportation of the aircraft parts, have been negotiated and approved by the board. Finding funding for the project has been a long and challenging effort. Funding and sponsoring arrangements are negotiated by the chairman and board members.

Aviation Museum Society’s board member Reino Myllymäki is responsible for the public relations of the project. He is assisted by two or three bloggers and by Jouko Tarponen, who is responsible for photographing the project’s progress in Pansio. All blogs and Caravelle news in the society’s Feeniks magazine are published also in English and this task is taken care of by two volunteers.

The members of Aviation Museum Society Finland were informed about the Caravelle project at an early stage. In the beginning of year 2021 the search for the technical team members was launched. During the spring the former Finnair mechanics Markku Ahokoski, Martti Saarinen and Kari Nyman answered the challenge. During the winter 2021-22 they led the discussion and assessment on how the aircraft could be disassembled and transported to Finland. This team has now been working in the project for a couple of years.

The disassembling (and re-assembling) of a passenger jet airliner means that a huge number of details need to be planned. The technical team has faced the task undaunted by the scale of the job. The task has included decisions on the main issues (how to disassemble the fuselage off the wing?), practical solutions (how to lift and turn the aircraft using the bridge cranes in the hall?), taking care of the small odds and ends (how to keep track of the origin of all screws and bolts which have been unfastened?), not to mention all kinds of issues which we ordinary non-technical people are not even aware of. These tasks have required good professional skills and the ability to foresee problems, and furthermore, also cool-headed decision making when something needs to be done which hasn’t been done before.

In the spring 2022 Ismo Matinlauri joined the technical team. His work has included recruiting the team of volunteers in Turku as well as coordinating the restoration work. Ismo has also managed all kinds of fixing and acquisition tasks.  For Ismo the Caravelle project is almost a full-time job when the Turku team works in the hall three days a week and the remaining two days are spent running errands and acquiring material.

During the project several people, many of them former technical staff from Finnair, have participated in solving technical problems and dismantling or restoration work. A group of enthusiastic volunteers without aircraft work experience has also joined the project, wanting to have a part in making aviation history. In summer 2022 there were about twenty volunteers from Aviation Museum Society Finland (and one or two volunteers from Sweden) disassembling the aircraft in Arlanda. This group is invited to join the Caravelle polishing session which will be arranged in Pansio this spring.

A team of about ten Turku area volunteers have been restoring the aircraft during the winter, working on three days a week. I take my hat off to these volunteers, they have been cleaning and sanding Caravelle’s surfaces for several months now! The sanding work is finally approaching the end and there is polishing and painting ahead.

In addition to Pansio, Caravelle restoration work is ongoing also in Vantaa, where two or three people have been preparing for sheet-metal work and repairing parts which have been brought from Pansio. The Tuesday Club of Aviation Museum Society has also participated in the project by repairing e.g. the damaged Caravelle’s radome and nose bulkhead.

Based on the estimations presented in this blog, it can be estimated that about 40 people have participated so far in the Caravelle project, some of them joining the team of volunteers for a single effort (such as the disassembling), others working on the project almost daily. Warm thanks to you all! Without volunteers this project would never have been possible. Hopefully in the following blogs we can read why they joined the team.

Caravelle III OH-LEA "Sinilintu" ("Bluebird")

Keskiviikko 29.3.2023 - Erja Reinikainen

Suomeksi

The Caravelle III, which was brought from Arlanda to Finland by Aviation Museum Society Finland, served in the SAS fleet with registration SE-DAF and name Sven Viking. In Pansio the aircraft is being restored to Finnair colours as its first Caravelle OH-LEA, Sinilintu (Bluebird). This blog tells about the long and colourful history of this aircraft.

In 1958 the Finnish airline Aero Oy (later Finnair) ordered three Caravelle IA passenger jets from the French Sud Aviation aircraft factory. The Finnish airline was one of the forerunners of air travel and was the fourth airline to order the new passenger jet type, after Air France, SAS and the Brazilian Varig.

The first jet aircraft in Finnish civil aviation was Sud Aviation Caravelle IA, which got the registration OH-LEA and was named Sinilintu (Bluebird). It was handed over in Toulouse on February 21st, 1960, and it arrived in Finland on February 22nd, 1960. The aircraft was flown to Finland by Olli Puhakka, who was a former fighter pilot and Knight of the Mannerheim Cross. The co-pilot on the flight was Olavi Siirilä, also a former war pilot. Among the guests of honor on the flight were minister of transport Arvo Korsimo, Aero Oy’s managing director Leonard Grandell, chief editor of the Helsingin Sanomat newspaper Yrjö Niiniluoto and maritime counsellor Antti Wihuri.

During the spring 1960 the Bluebird was followed by Sinisiipi (Bluewing, OH-LEB) and Sininuoli (Blue Arrow, OH-LEC). These three aircraft were later modified to type Caravelle III. The fourth aircraft was already a Caravelle III when it was purchased in 1962. It was named Sinipiika (Blue Maid, OH-LED).

During its service in the Aero fleet the Bluebird appeared in three different paint schemes. It was delivered in its first appearance, where the rudder was blue, and the name Aero was written in large on the upper part of the vertical stabilizer. In the second paint scheme the rudder was blue and a blue cross on the vertical stabilizer replaced the text. Otherwise the paint scheme was identical to the first one. The third painting was done when the aircraft was updated to type Caravelle III.  This is the appearance into which the former SAS SE-DAF will now be restored. The paint scheme can be seen in the visualization image on the front page of the Caravelle-project. When Finnair celebrated its 40th anniversary, a special anniversary logo and text were added on the aircraft.

In the Finnair fleet the Caravelle had 16 seats in the first class and 75 in the tourist class. Starting from April 1960, the Caravelles operated on routes to European cities. In the beginning the destinations were Stockholm, Copenhagen and Frankfurt, followed by several other cities during the coming years. The Caravelles replaced the Convair 440 Metropolitan piston engine aircraft in Europe, and they were transferred to domestic routes. In late 1961 Oulu was the first domestic route operated with passenger jets.

A Finnish speciality was flying the Caravelles with only two pilots, when other airlines had two pilots and a mechanic in the cockpit. Another remarkable difference was the surrounding and existing environment, which was why the Aero Caravelles had a brake parachute installed. The Caravelle III had Rolls Royce Avon engines and there was no reverse thrust in them to assist in the braking. The brake parachutes were only used when the friction conditions on the runway were really poor. The pilot opened the brake parachute by pulling a handle during the landing run. When the aircraft left the runway, the parachute was released by pulling the same handle. The technical ground crew then collected the parachute for reassembly.

The OH-LEA Bluebird flew its first flight on February 11th, 1960. It belonged to the Finnair fleet in 1960–61 and logged 9091 hours. The aircraft was sold back to Sud Aviation on December 4th, 1962, and it was flown to France on September 20th, 1964.

The following user of the Caravelle was the German LTU, which got the aircraft on February 12th, 1965. It was registered as D-ABAF and named Nordrhein-Westfalen. The next user was Transavia Holland. It rented the aircraft between January 30th, 1969, and April 16th, 1970, as PH-TRM.

From the Netherlands the aircraft returned to France, where it was registered as F-BSRR in Air Inter’s fleet where it flew from March 19th, 1971, until December 1980. During this time the Caravelle was rented to Royal Air Maroc and SNIAS, among others, having different registrations.

Air Inter sold the aircraft to Altair in Italy, where it was registered I-GISA. It was removed from service in September 1983 with 37 532 hours on its log. But the story doesn’t end here.

From Italy the aircraft was bought to Congo by IAC Airlines. In Congo it was registered 9Q-CPS and it was named Santeny. The last airline to use the Caravelle was Air Transport Service, which flew it until 1994. The Caravelle was scrapped in 1996 at the N’djili international airport in Kinshasa, Congo.

As we can see, OH-LEA was an individual with a long history. It served for 36 years, and it had more user airlines and operators than any other first generation Caravelle.
