Maintenance objectives
Cost Decrease the maintenance costs Make the maintenance work easier
Safety Increase Safety with maintenance low cost actions
Availability Increase the aircraft availability
Business Improve the EC business in terms of Maintenance
& Service Propose a meaningful service/product combination
-
helicopter maintenance specificities
Airplane Helicopter
Wild body vhicule compact
Equipments all over the AC Centralized equipments
Same product for each AC Personnalised and adaptable HC
-
Airplane Helicopter
Long range Take off and landing = stress
One mission type A lot of different mission
High altitude Less than 5000m
helicopter maintenance specificities
-
Airplane Helicopter
Low vibration stress Hight mechanical stress
Specific customer Diversity of customer
Availability as priority Failure localisation to avoid no failure fond
The airplane and the helicopter are two vehicules using the samemaintenance mode but in different objectives and different stress.

On board failure management
Problematic links to the aircraft diagnostic False Failures: False warnings Failure Localisation Ambiguity (intrinsic) Failure Propagation
All these problematic lead to : false removal (between 30 and 40% of maintenance
operations) Longer maintenance time Lost of confidence in the diagnostic tool Customer is not satisfied
