- The internal cooling ducts 3, 4, 5 and 10 of the rotor blade No. 1 of the first T1 turbine station (HPT), were blocked with silicon contamination, probably caused by the intake of sand.
- Fracture of the No. 1 rotor blade of the first T1 (HPT) turbine station, caused by stress and fatigue; from areas where there was previously an IGA (Intergranular Corrosion) attack.
- Not having carried out the Boroscopic Inspection to engine No. 1, as stipulated in the Maintenance Program (Chapter 8 Engine Maintenance), every 600 hours.
