Airlines have been instructed to conduct drug screenings for all pilots. This move aims to enhance safety protocols due to concerns over substance use among crew members. The testing process has begun and is expected to be completed by next July.

The decision follows an investigation into a flight that experienced a rare malfunction, resulting in a loss of altitude. The incident involved the failure of all three hydraulic systems, which led to the autopilot being disconnected.

Further details about the directive and the investigation are available from the relevant authorities, including the Directorate General of Civil Aviation.
