JTSO Authorisations - Import

1.1 The JAA Procedures for Joint Technical Standard Order (JTSO) Authorisation purpose (see Administrative & Guidance Material, Section 3 - Certification, Part 2 - Procedures), describe the process for granting JTSO Authorisation for an article by a National Aviation Authority (NAA) of JAA. The process includes a standardisation mechanism, allowing mutual acceptance by all JAA-NAA of granted JTSO Authorisations.
1.2 When a NAA has issued a JTSO Authorisation in accordance with these Procedures, the JAA Certification Division publishes it in this document.
1.3 Some NAA may still have national administrative requirements with regard to the approval of equipments. See Paragraph 3, below.
1.4 A JTSO Authorisation does not cover the approval of the installation on an aircraft.  Any NAA being involved in the certification of a domestic product fitted with such articles may request any data about design and compliance demonstration.  It is the responsibility of the product or modification designer who specifies its use to ensure that it meets the relevant installation design requirements for the product.  Similarly, equipment required by JAR-OPS or other operational requirements to be installed or carried in an aircraft must be compatible with the intended operation of the aircraft.
