All aircraft which are not designed by DG Aviation but that are serviced by our company need to sign a Service Contract. You may only access our supply of services for the aircraft listed below after concluding a Service Contract.

Service-Contract Benefits

There are two different options to choose from for the Service Contract. The “Basic” contract and the “Full” contract. You will find an overview of the individual services in the following table.

Benefits “Basic” “Full”
Assured type support and continued airworthiness X X
Technical support X X
Spare parts support (as long as technically possible) X X
Free of charge TN and AD documents X X
Free, necessary construction plans and drawings X X
Cover sheet for the maintenance manual X X
Free electronic manuals X
50% discount on inspection programmes to increase aircraft lifetime X
10% discount on labour cost ordered from DG Flugzeugbau within the scope of maintenance work up to the amount of the valid contract X X
Discount for owners with several aircraft, from the 2nd aircraft onwards X


If you have concluded a “Full” contract and would like to have a Basic contract from now on, please inform us informally by the end of the calendar year. The reduced contract will then apply from the beginning of the following year.

Customers who order a new glider from us will also receive the support of their old DG and LS gliders in their possession free of charge as an additional “after-sales service”!


Full contract

The fee for the full contract applies to each current calendar year – irrespective of the date of conclusion of the contract. All prices in parentheses are inclusive of 19% VAT, where required by law.

For new contracts the first year costs € 490.00 net (€ 583.10) in each subsequent year € 245.00 net (€ 291.55) – in each case per aircraft.

In the case of a proven purchase of a used aircraft and the conclusion of a support contract in the same year, the reduced amount of 245.00 € net applies.

For owners with several aircraft, the second and each subsequent aircraft costs a flat rate of 345.00 € net (410.55 €) and in each subsequent year 150.00 € net (178.50 €) – in each case per aircraft. 

Basic contract

The fee for the Basic contract applies for each current calendar year – irrespective of the date of conclusion of the contract. All prices in parentheses are inclusive of 19% VAT, where required by law.

For new contracts, the price of the Basic version is € 490.00 net once (this includes the manuals) and € 180.00 net in each subsequent year – in each case per aircraft.

For contracts which are continued as a Basic contract by the previous owner for 180,00 € net, no manuals are included.

In case of proven purchase of a used aircraft and conclusion of a support contract in the same year, the reduced amount of 180.00 € net (214.20 €) per calendar year and aircraft applies.



What do I have to do to conclude a Support Contract?

You should download the text of the contract and fill it out, preferably with a text program. If you fill it out by hand, please enter the email address very carefully!

Sign the contract and send it to us.


What happens next?

You will receive an email confirmation and the new maintenance manual with the individual cover sheet.


I fly an aircraft built by you, but I bought it second-hand. Do I have to sign a maintenance contract?

No. All aircraft built by DG Flugzeugbau GmbH after 1996 are covered by a lifetime after-sales service. You acquired this service when you bought your used aircraft. Of course, this also applies to customers who own a glider built by us and wish to sell it. Their buyer does not need a service contract either.


We are an association and operate several of the aircraft concerned. Does each one need a contract or do we only pay the sum once?

Each individual aircraft needs its own Service Contract. But from the second aircraft onwards, an owner with several aircraft pays less!


What happens to my care contract when I sell my aircraft?

Then the contract ends at the end of the year. In this case, please provide a proof of the sale.


You write something about a discount for maintenance/service work. What do you mean by that?

If you bring us one of the aircraft concerned for an annual inspection, repair or other modification, you will receive a discount on the cost of the work, which can be up to the amount of the service contract for the year. Please ask our Service Department.


What actually is type support?

Anybody who designs, builds and sells an aircraft and wants to produce a series of the model has to apply for an approval. With the issuing of an approval he will receive engineering specifications. His name will be registered as type servicer (type certificate holder) on the paperwork. If for any reason (bankruptcy, abandoning the business, etc.) he drops out, this does not indicate that all aircraft of the series are grounded. Many aircraft are flying in small batch series without having a type servicer. If an accident occurs which is due to a structural failing, a technical will be issued. In this case, without having a type servicer appointed, all aircraft have to stay on the ground.

The EASA has defined the type servicer’s responsibilities in a comprehensive system of rules. You will find them on the EASA homepage when looking for EU-VO 1702, part 21. The extent of type servicing is defined by a sort of “sovereign act”.

The type servicer’s first responsibility is “to be present”. He is the contact person for all questions about the safety of the particular model. He is responsible for the series, not for a particular aircraft. That is the responsibility of an approved maintenance company.

Furthermore the EASA determines which demands the type servicer has to meet. He has to have at least three autonomous engineers. He has to be certified and must regularly undergo audits (and pay fees). He also has to provide a quality management.

The type servicer is a pilots’ natural contact person in all technical matters.

Worldwide, the type servicer is the contact person for maintenance companies, which may call him for extensive assistance with difficult repairs, e.g. particular repair instructions, charts, structural designs etc.

Last but not least the type servicer is responsible for keeping up the construction safety. That is to say an accident with a structural failure is a subject to be reported to the authorities, EASA and worldwide. The type servicer will have to comment on the matter, to verify if an operating error or a fault in construction caused the failure. If the latter is the case, he will have to work on a solution which precludes the occurrence of a similar accident with another aircraft of the model range. The conclusion will be a technical note and an airworthiness directive (AD).

The type servicer is also responsible for the compilation, administration and distribution of aircraft manuals. The compilation is part of the approval process, but the consecutive data administration is not less important; new perceptions and implications to ensure safe air traffic have to be passed on to pilots.

As you can see from the information given above, the type servicer’s duties are enormous and therefore cost-intensive!
