SUBJECT: Airworthiness Directives for engines, propellers and other vendor equipment

BACKGROUND: Procedures and regulations regarding issuance of Swedish Airworthiness Directives (SAD) are defined in Swedish Civil Aviation Regulations, BCL-M 1.11.

This regulation stipulates that LFV shall issue an SAD in each case a foreign Airworthiness Directive has been issued by the state of manufacture for an engine, propeller or other vendor equipment that is used in an aircraft which has been certificated by LFV and LFV has agreed that the required action is appropriate.

This regulation has with a few exceptions not been followed up to now. This means that an operator may formally, with reference to BCL-M 1.11, elect not to comply with foreign Airworthiness Directives. On the other hand, the Swedish regulations for maintenance, BCL-M 3.2 stipulates that each maintenance organization for transport category aircraft must have access to and follow all Airworthiness Directives issued by the state of manufacture. However, the wording in this regulation is ambiguous and can be misinterpreted as being limited to airframe Airworthiness Directives only.

This SAD is issued to

a) Eliminate the possibility of misinterpretation of the wording in the regulations regarding mandatory compliance with Airworthiness Directives issued by the state of manufacture for engines, propellers and other vendor equipment

b) As a service publish a list of vendor Airworthiness Directives published by the State of Manufacture (or Design)

REFERENCE DOCUMENTS: Swedish Civil Aviation Regulations, BCL-M 1.11 and M 3.2

Perform all applicable actions required by Airworthiness Directives issued by the state of manufacture (or Design) for the engines, propellers and other vendor equipment that are part of the SAAB SF340A and SAAB 340B type design. An alternate means of compliance or exemption may be approved by LFV, Aviation Safety Department.

COMPLIANCE TIME: As defined in the foreign Airworthiness Directive

EFFECTIVE DATE: 17 February, 2000
