GoAir flight G8150, an Airbus A320neo suffered a no.2 engine (PW1127G) malfunction and diverted to Lucknow, India.

The aircraft landed safely at Lucknow. After landing during inspection oil traces were observed on the exhaust area nozzle, tail cone, drain mast & TR cowl area underneath drain mast.
Probable Cause of the Incident
The IDG oil pump drive gear shaft assembly fractured during engine operation as its resonance response to certain engine operating conditions resulted in a high cycle fatigue fracture. This fracture of IDG oil pump drive gear shaft assembly and consequent damages to other MGB components resulted in various ECAM fault including Engine Oil low pressure and subsequently to engine failure and IFSD (Commanded).
