What is the first step in the AMAD servicing procedures?

The first step in the AMAD (Auxiliary Matching Accessory Drive) servicing procedures is to inspect the oil filter delta P. This inspection is crucial as it helps to determine the condition of the oil filter and identifies any potential blockages or issues with oil flow within the system. Monitoring the delta pressure across the oil filter provides important information on the filter's performance and whether there is an adequate oil supply for the AMAD system.

Starting with this step allows maintenance personnel to address any immediate issues that may affect the overall performance and reliability of the AMAD before proceeding with any further servicing tasks. By ensuring the oil filter is functioning correctly, the maintenance crew can avoid complications that might arise from proceeding with servicing without first confirming that the oil circulation system is clean and operational. This preventive approach ensures the longevity and efficiency of the aircraft's systems.
