Many of us have probably wondered why The Aviation Herald has not reported about this quite serious incident so far. And here is why: it did not happen. The Aviation Herald indeed had researched this occurrence and dismissed the whole story. "According to radar data", The Aviation Herald states, "the aircraft, departing Mumbai on Aug 8th, was en-route over Turkey on Aug 9th at FL340 but never busted the flight level. Transponder data always showed it between 33.975 and 34.025 feet".sn26567 wrote:The (female) co-pilot has claimed she was busy on her tablet and did not notice that the aircraft had lost altitude. A call from an alarmed Ankara ATC is what jolted the pilots into action.

The flight departing Aug 7th and being over Turkey on Aug 8th was cruising at FL320 and had no altitude deviation, too.
So what happened?
According to Simon Hradecky, editor The Aviation Herald, the incident (quid non) was reported to the Indian DCGA by one (1) anonymous SMS text message. The DGCA however opened an investigation whether there would be any substance to the claims in that SMS. For the Times of India, the fact that the Indian DCGA opened an investigation was a full confirmation that it had happened.
Additional factors that point out to a false report by Times of India:
- Why did the Indian DGCA not receive a notification from Turkish ATC and/or Turkish CAA, supplied by the controller querying the aircraft?
- How can an aircraft on autopilot descend 5000 feet without interaction? If the autopilot had been inadvertently disengaged, a very loud wailing sound would have alerted the pilots that the autopilot has disengaged. If the pilot was asleep and the co-pilot was working on their iPad, both would have heard that wailing sound.
Did nothing happen then?
Actually, it is indeed possible that an irregularity occurred. Could be that captain had left the cockpit for a nap (in violation of regulations), and/or could there have been an inadvertent autopilot disengagement, caused by a violation of rules regarding scheduled cockpit naps. Perhaps some crew member (or a passenger?) noticed this, and sent an anonymous SMS to the Indian DCGA?
