A4A MPIG AHM Working Group results MSG3 is • An MSG3 update, described in a CIP (Candidate Issue ready for Paper), has been developed by the MPIG AHM WG and presented to the MPIG (Maintenance Program Industry AHM Group) in September 2017. • The proposed solution is introducing a Level 3 analyses sheet to the existing MSG3 systems analysis methodology, Issue Paper 180 which can be used optional by the TCH to identify a AHM (Aircraft Health Monitoring) capability as an alternative to a MSG3 classic MRBR task. methodology has been updated to • CIP has been successfully presented at the IMRBPB allow AHM as an (International Maintenance Review Board Policy Board) meeting in April 2018 and published as IP180 “Aircraft alternative to the Health Monitoring (AHM) integration in MSG- 3”. classic scheduled CIP CIP IATA EMG MPIG WH CIP maintenance task .

Aircraft Heath Monitoring it’s more than a ECAM message! Watching This is where the from ground story stops today … its not AHM! We have to ECAM predict and not to react! Data analysis Action MCC AHM is the Sensing, Acquisition, Transfer, Analysis and Action/s taken (SATAA) with data generated from specific Aircraft systems measuring condition, reduced resistance to failure or function degradation. This unified process intends to optimize the timely scheduling of required maintenance prior to operational impact. 12 26th NOVEMBER 2018 5th Paperless Aircraft Operations and RFID Conference
