SERVICES The services included in Part B of this Annex, need to be provided at an aerodrome. In some cases, these services are not directly provided by the aerodrome operator, but by another organisation or State entity or combination of both. However, the aerodrome operator, being responsible for the operation of the aerodrome should have arrangements and interfaces with these organisations or entities to ensure that these services are provided according to the legal requirements. The method described above meets with the intention of an integrated Safety Management System that helps the aerodrome operator to ensure the safety objective of the service provision is being met. In completing this action, the aerodrome operator should hereby been seen to discharge its responsibility by employing the procedures mentioned above, furthermore, the aerodrome operator should not be understood to be directly responsible or liable for non-compliances by another entity involved in the arrangement.
