Global Maintenance Agreement (GMA)

The Global Maintenance Agreement (GMA), commonly known as  ‘Power By the Hour’ (PBH) is an innovative ATR concept to provide ATR Operators with customised and flexible solutions for on-aircraft and off-aircraft maintenance.

For 20 years, through the GMA, ATR has contributed to reducing operators’ maintenance costs and boosting their operations.

This highly flexible solution allows to meet a wide range of airlines’ specific needs (based on the operator’s choices in investment, local resources, aircraft fleet, expected use, and on-site stock protection level).
