Service Bulletins & Letters

Ensuring the continuing airworthiness of Jabiru products
Jabiru aircraft operate under various approval systems around the globe, including Type Certification, Light Sport Aircraft and Experimental. Jabiru has developed a Continued Operational Safety (COS) program for all Jabiru products to ensure the continuing airworthiness of all fleets. The Jabiru COS for all products is compliant with ASTM standard F3198 – Light Sport Aircraft Manufacturer’s Continued Operational Safety (COS) Program.
The development of Service Bulletins and Letters is a time consuming and laborious activity as it typically depends on an issue coming to light in operations on a repeated basis, before the engineering analysis is conducted and fleet wide recommendations can be made. On occasion, Jabiru will directly contact owners prior to the issue of a service notice to gather information or provide informal advice prior to a service notice being published.

It is in the best interests of all Jabiru product owners to have their products registered with Jabiru, so that prompt and direct advice can be provided to owners. The best way to do this is to register your products through the members section or contact us directly (link). If you sell your Jabiru product, please advise us of the new owner’s details.

Jabiru strongly recommends the implementation of all service notices, in the interests of safety, regardless of the product’s certification basis or the aviation authority under which the product is operated.

Whether a service notice is mandatory depends on the operational rules in the country in which the product is registered.

For operations in Australia, Civil Aviation Safety Regulations 1998, Part 91.900 requires pilots of Light Sport Aircraft to comply with any safety direction or requirement issued by the aircraft’s manufacturer. Similar requirements exist for all National Aviation Authorities (NAA) that recognise the Light Sport Aircraft category.

For Type Certificated products, this notice must be complied with if it has been issued as an Airworthiness Directive by the relevant authority.

For products operating under an Experimental Certificate (or similar) the owner of the product is responsible for the design and continued airworthiness of the product.

The following service notices are current for all Jabiru products.
