India's DGCA released their final report concluding the probable cause of the incident was:
Cabin pressurisation failure occurred due to malfunction of flow control valve no. 2 at higher altitude.
The DGCA analysed: "Flow Control Valve No.2 was sluggish and was confirmed to be faulty. It implies that the aircraft was being served by only one pack for air conditioning. The aircraft was flying at high altitude of FL 390. There was a fault message for flow control valve no.1 also. However, the fault on flow control valve no.1 could not be confirmed during check in the shop. This kind of anomaly in serviceability of flow control valve is possible as environmental conditions are not the same at higher altitude (FL 390) and on ground. It implies that flow control valve no.2 malfunctioned and bleed through flow control valve no.1 was not sufficient to maintain pressurisation in the cabin at higher altitude. Insufficient bleed led to depressurisation of the cabin. Thus, it was malfunction of flow control valve no. 2 at higher altitude that led to aircraft cabin pressurisation failure."
