Heinkel 115 the project has reached a new small milestone in that the center section has now been put in place in the "iron bed" that we have built. The purpose of the facility is for the center section to lie in it while work is being done on the wing and the float attachments.
We are now in the process of building and installing jigs that will help us fix them 8 wing the fasteners when these are to be re-mounted on the center section.
The Aviation History Museum Sola is currently an ongoing and large construction project here. In addition, a major regrouping of the aircraft that we have on display will be done in our old exhibition hall. The high level of activity leads to a great need for voluntary efforts from the museum's members. This also affects the amount of work we are able to do on the Heinkel He 115 project.
Nevertheless, Egil Thomsen managed to make a new pilot's seat during the autumn. When the aircraft was raised in 2012, much of the equipment needed to adjust the pilot's seat height was still intact. In addition, the reinforced plate behind and under the seat was in good condition. The pilot seat itself, with associated frame made of aluminum tubes, however, was completely gone.
Egil has reconstructed the tube frame and then made a new seat pan itself. This is bolted to the tube frame. The result has been very good. To be able to raise and lower the seating height, the seating arrangement was equipped with a separate hydraulic system. A hand pump was mounted on the side of the seat. The hydraulic pump and some of the valves that have been in the system are still in good condition. Egil is now working on finalizing and assembling this entire system. We are not yet ready to be able to reassemble the seat arrangement in the cockpit again. This will therefore be exhibited for a period in the museum's exhibition.
Throughout the winter, we will continue to work on reassembling equipment in the cockpit and Kanzel. This is equipment that we have previously taken out of the sections in order to preserve it
The center section has corrosion damage throughout 8 wing mounts with associated structure. The same applies to all four float mounts. In order to work with these injuries, the center section must be placed in a "crib". In addition to the "crib", we need jigs to ensure that we are able to reassemble the wing mounts in the correct position. The National Antiquities has given us financial support to be able to build a jig with an associated "crib". Work on building these is now well under way. We plan to be able to start work on repairing the corrosion damage to the center section during 2024.
The museum services in Rogaland by conservator Eirik Aarebrot have preserved the aircraft's starter batteries for us. These are two twelve volt acid batteries that we in 2012 found at the back of the tunnel in the center section. The batteries were behind 70 years on the fjord bed still in a usable condition. We have attached some of the content of the reports that Eirik made after the conservation was finished.
Conservation of batteries:
"The batteries had heavy deposits on the surface that resembled rust. There were also some holes and penetrations in the steel boxes. The battery terminals and lead contacts on top of the battery had some white deposits and corrosion. The top, which was made of pitch, had a number of cracks. All the acid meters, which is part of the corks, had broken off and fallen into the batteries.
The caps were removed and the batteries were rinsed out with warm water.
The steel cases were scraped clean of deposits using a scalpel. It turned out that the condition was much better than first thought. Large parts of the steel plate still had their fine original black surface. However, there were some minor holes which means that the batteries are leaking. These were sealed with Cosmoloid 80, which is a microcrystalline wax with a melting temperature of 80°C. The steel plates were preheated with a heat gun and melted wax was poured into the holes.
The battery poles with connection points were cleaned by knocking off the deposits with a small hammer. The battery cells were filled with Fluidfilm Liquid A, which is a thin lanolin oil.
The following materials have been used in connection with the conservation:
Cosmoloid H80 (Microcrystalline wax)
Fluidfilm Liquid A (Thin lanolin oil)
Loctite Repair Extreme ( Glue used on corks and acid meter tubes )»
Throughout the autumn and winter, we have spent a lot of time reviewing the center section. This is to get an overview of what corrosion damage is on the section. Much of the section is undamaged, but there is corrosion on and in areas around important load-bearing parts in the section. These are damages that need to be repaired. Typically, it is mostly on the wing- and float attachments with associated structures that require intervention. We have carefully documented the damage in the form of work descriptions and photos.
Repairing the damage will require a significant number of man hours. We are now considering several options for carrying out this work.
An alternative that we are considering, is to outsource the work to an external party. We have therefore resumed our previous contact with the International Aviation Museum Foundation. Their business was established in 1992 and the workshop is located in Hungary. Since we in May 2013 had the previous owner visit, the business is split in two with different owners. The business is, after having been involved in several German and Norwegian restoration projects, well acquainted with work on German WW II aircraft. They have previously done work for us, then at Arado 96 motor cowlinger.
20 On February we again had a visit from the International Aviation Museum Foundation. This time it was Laszlo Juhasz and Ferenc Foldes who visited to take a closer look at the center section. We plan to pay them a return visit soon when we have free time for such a trip.
We have lately been working mostly on preparing to move the center section out of the concrete hall and into the workshop.. This is because we will start work on repairing local corrosion damage in the center section. These lesions are mainly localized to the areas within the wing, float and engine mounts. This will be a time consuming job. If we are lucky, we will not have to do other and more intrusive work on the center section. Ultrasound examinations, as IKM Inspection AS has done for, shows us that fortunately there is little corrosion on the most complicated parts of the support structure in the center section.
The center section will take up a lot of space inside the workshop. To free up this space, it has been a priority to work with the Caproni nose section. The latter has of course had some consequences for the progress of the work with He 115 cockpit and nose section. The first relocation of the center section inside the concrete hall has now been completed. The plan further now is to saw out a five meter wide opening in the west- the wall of the concrete hall. Through this we will then roll the center section. When the center section is out of the concrete hall, we must immediately close the opening in the brick wall. The process of sawing out the hole in the concrete, move out the center section and then close the hole in the concrete wall must happen in one and the same day. We plan to do this during the autumn.
When we raised the plane, we found in the Kanzel parts of a measuring instrument that we did not understand the use of. We understood that these were parts of a drift meter, but we were unsure how this had been mounted in the plane. The drift meter was then given a temporary preservation and then stored. On the starboard side at the front of the Kanzel there is a rectangular hatch. Behind this hatch we found the remains of a magnesium bracket and the remains of a cloth cuff. We did not understand what this hatch and bracket had been used for. In pictures by Heinkel 115 this hatch appears, with few exceptions, as closed.
Then we are lucky and are contacted by Marc Bressan who lives in Switzerland. Marc Bressan has a very solid knowledge of and experience with German aircraft instruments. He had restored and built up a complete drift meter himself. Marc offered us to share with us his extensive knowledge and documentation about He 115 Tribsgërete. He sent us a bunch of pictures that showed us what a complete system should look like and work.
The information we received from Marc showed us that we needed a lot to have a complete system for drift measurement.. Marc now offered to complete and donate to us parts he had left over from the restoration of his own Tribsgërete. With these parts we were now in possession of a complete system for drift measurement. The drift meter that we found in the plane in 2012 was only temporarily preserved and did not open up for interior cleaning and preservation. Marc opened this for us and did a thorough internal preservation of the meter for. This facility for measuring drift, will when these are mounted in the aircraft show these well again forward in the Kanzel. We owe Marc Bressan a very big thank you for the help the project has given.
This equipment, along with everything else we have found on board, shows that a very well-trained crew was needed for them to be able to operate and benefit from all the aircraft's systems.
The following pictures we have mainly received from Marc Bressan:
In this post, we will show some pictures of the parts that are now in place in the cockpit.
Behind everything that is now mounted in the cockpit is a lot of work that the pictures can not make visible. This applies to both work with electrical components, work with instruments, as well as work with photos and documentation.
In addition to the work on the cockpit and the Pulpit, we have also begun to prepare what we will have to do with the center section in the years to come..
It is a guiding principle that we should as far as possible utilize all the original parts that we found in the plane when it was raised in 2012. At the same time, we try as far as possible to make things work again.
We all wish you a good summer…
We have received the good news that Heinkel He 115 The project by the National Heritage Board has been allocated funds for the work on the aircraft's center section. The allocation is limited to 40000 kroner and will be used for preparations and construction of a gig that we need to be able to work on the center section's supporting beams.
Before we can start the work of building such a gig, we will first map the extent of corrosion damage to the supporting beams.. To make such a survey, we consider using NDT as a method. On that occasion, we are already in contact with IKM Inspection AS who have been on an inspection and looked at the center section. Their preliminary opinion is that the use of ultrasound as a method will give us the best result. They will now make a more comprehensive assessment of how they can best make a survey of corrosion damage in the supporting beams..
The year 2020
The year 2020 was a good year for Heinkel 115 the project through which many positive things have happened.
We have for several years had restrictions on the type of work we could do on the plane. During the past year, the Armed Forces Museums have largely been abolished these restrictions.
It formerly Heinkel 115 the steering group has been closed down. As a replacement for this a support group has been established with members from the Friends' Association, as well as two conservators engaged by the Jærmuseet. This solution gives us that working with the aircraft an easy access to a very versatile experience and competence.
It also in over the past year there has been a unanimous understanding that it can be necessary to make some interventions on the center section. This mainly applies to supporting beams, with associated attachments for wings and floats. This has led to it now is working to find solutions for how such work can be completed. Our goal is still to make small interventions and preserve as much as possible much of this section.
It has Throughout the year, work has been done on a number of different sub-projects. I de cases where equipment is completely destroyed, we integrate what may be left of the original equipment in the new one being built.
An example is the work that has now been completed to build a new hydraulic hand pump for flap and opening of bomb hatches etc.. Of the original pump, only handles remained, mechanical transfer to stamps, pistons and end caps. Said parts are built of high-quality materials and had done well down on the fjord bottom. All the pump housing and cylinders, on the other hand, were almost completely corroded. Pump housings and cylinders have now been rebuilt and the pump can now again be used to pump oil. The above mentioned remaining parts have been integrated in the new pump.
It is also throughout the year made a new instrument panel for the cockpit. Although most of the original panel was gone when the plane was lifted, will still the new panel be equipped with original instruments. These are instruments that were found in the aircraft and which has now been preserved and in some cases partially rebuilt.
Through At the same time, we have gained a good overview of the work with the instruments which instruments and other similar equipment have been in the cockpit of the aircraft and nasal section.
Another of the bigger things that have been done through 2020 is the work of rebuilding the system for suspension and transmissions from the rudder and toe pedals. Also here is remaining original parts have been integrated into the new finished product.
It has also become worked hard to preserve original electrical equipment. These are things like circuit breakers, switches, terminal blocks and many other smaller electrical components. The work is a time-consuming work of patience that is now really beginning to show again in form of finished preserved parts. These have either already been reassembled in the plane, or in stock ready for use..
The big and extensive cableway along the port side of the cockpit was also completed early in 2020
The outer the section of one engine stand was completely missing when the plane was lifted in June 2012. This is because one engine was salvaged before the plane sank in December 1942. It the missing section has been rebuilt during the autumn. At the same time, we have what we have of original brackets and other equipment for the motor brackets have been reassembled on the engine jacks.
Photo sharing archive and documentation is a time-consuming task that runs as long as the project ongoing. It is also through 2020 been working a lot on these things.
When the plane was raised in June 2012 a few smaller parts were left at the site. It was last year, several ROV dives were made at the crash site in Hafsfjord. Although the plane was unusually complete sea wreck to be, also missing our plane things that can not be found elsewhere. A new application has therefore been sent to raise He 115 parts from Limingen.
Efforts Heinkel He 115 has been going on all summer without the usual break that the participants' summer holidays tend to bring. Such has also we have been influenced by Covid 19.
Much work has been done to create a new instrument panel cockpit. We have only a few cm of the original panel2 left off. Even if the panel is new, it will still be filled up by the original instruments who was on the plane the day it crashed.
A lot of impressive work has also been done to recreate parts for suspension of side rudder pedals, both for pilot and for navigator. Some of the parts of this large system were almost completely gone when the plane was lifted . Again has managed in a good way to intrigue some new parts in among the many originals parts.
A curiosity is that it has managed to get light in again the hand lamp that was placed in a box in the back of the telegraph operator cockpit.
Work is also currently underway to make new the missing parts to one engine stand. These are parts which we are missing since one engine and both floats were salvaged right after that the plane had crashed.
It is also gratifying that we will soon be able to continue the work to repair the corrosion damage in the supporting beams in the center section. The idea is to do necessary interventions to preserve the residual strength of the load-bearing structure, and in a as far as it is justifiable, to preserve the rest of the center section. The idea behind this approach is to be able to preserve as much of it as possible center section as original.
Over time, we have searched extensively for information on an instrument with a associated system that was located on the starboard side of the Kanzel. We have now received a great and informative answer from Armin Züger in Helsinki. He had read our request in a previous post on this website, se link; http://heinkel115.com/2020-06-11/?lang=en
Attached you can read Armin`s answer.
There was some open questions about a so-far unknown instrument, related to torpedos.
There is an operation manual: D.(air)T. 7212 "Description, Operation and maintenance of the PVC drop weapon 1006 A“ (which I have attached as a pdf document) that might shed a bit more light in this.
In the picture there some words “Scharf Torpedo Fallschirmlot Blind” on the unknown instrument.
“Scharf” and ”Blind” means basically “disarmed” and “armed” (i.e
Mixed,options applicable to his clinical condition and the related sildenafil dosage.
“Fallschirmlot” is another expression for Luftmine (parachute mine, LMA and LMB ), you will find this also in the manual
Now the interesting part:
The document contains also a schematic picture of a He 111 cockpit. There is one lever named BlindScharfhebel. And I guess this is what the unknown mechanism of your He 115 is. It’s a lever to arm/disarm the torpedo (in case of the He 115 maybe combined with some other functionality).
We have during the time that has passed since last status update of the homepage, got clogged the parts of the end walls of Heinkel hall which is dressed with timber cladding . The use of dehumidifier inside the concrete hall has meant that this cladding has dried out and opened to allow moisture to migrate through all the gaps which are encountered in planking. The consequence of this has been that the weather conditions on the outside of hall in a substantial influence to the humidity inside the hall. We can Now measure that it is both a clearly more stable and significantly lower relative humidity inside the warehouse.
It is now summer and vacation time and this will affect the activity around the Heinkel He 115 project a while forwards .
It has also been worked on both with the plane's instruments and to make copies of brackets and mounts for rudder pedals

The main priority for the Heinkel He 115 the project is to preserve the aircraft so intact and untouched as possible. Yet there is a fact that the aircraft has remained at the bottom of a inlet in 70 year. Salt therefore drawn between aircraft many joints . Our challenge is therefore still finding a method that best safeguards the desire to make small engagement in the plane while ensuring that aircraft do not over time destroy. We looking therefore still active over a wide registry to find this. In one end of this registry finds a possibility of conducting a electrochemical desalination, while at the other end finds a possibility of completely or partially to dismantle the aircraft parts . The aircraft's center section is a complex construction with many very tight joint. It would therefore be difficult to remove salt from these joints. As part of the studies round choice of method we have recently spent some time on mapping how the center section is actually built. This is to provide an overview of how a whole or piecemeal removal thereof can carried.
Efforts Heinkel He 115 project since January 2018 been hampered of the Armed Forces Museum is in a process where they will consider future ownership of equipment that is lent on landfill agreements. It now appears that this process has come so far that they imposed restrictions on work on aircraft soon can be raised.
