The Air India Express Flight 812 crash, one of India’s deadliest aviation disasters, continues to be a subject of intense scrutiny more than a decade after the tragic event. The recently resurfaced details from the cockpit voice recorder (CVR) transcript offer a chilling, moment-by-moment account of the flight crew’s actions and communications leading up to the devastating crash. Aviation experts who reviewed the transcript have pinpointed critical factors, including a compromised landing approach, unstable flight conditions, and a fatal delay in executing a “go-around” procedure, as primary contributors to the disaster. The revelations from the CVR transcript underscore the complex interplay of human factors, technical issues, and environmental conditions that can contribute to aviation accidents.

The accident occurred on May 22, 2010, when the Boeing 737-800 operating as Air India Express Flight 812 from Dubai to Mangalore, India, overshot the runway while landing at Mangalore International Airport. The crash resulted in the loss of 158 lives, with only eight survivors. The CVR transcript, a crucial piece of evidence in the accident investigation, provides a detailed record of the conversations and sounds within the cockpit during the flight’s final moments.

Aviation experts analyzing the CVR transcript noted that the pilots seemed to have misjudged the aircraft’s descent rate and landing distance. The aircraft approached the runway at a higher-than-normal speed, which, compounded by the limited runway length at Mangalore International Airport, made a safe landing increasingly challenging.

One of the critical observations from the CVR transcript is the presence of what experts describe as “longitudinal instability.” This refers to the aircraft’s tendency to oscillate or deviate from its intended flight path along its longitudinal axis, making it difficult for the pilots to maintain a stable approach. The transcript reportedly captures instances where the pilots struggled to correct these deviations, indicating a potential loss of control in the critical moments before landing.

The CVR transcript also suggests a significant delay in the pilots’ decision to execute a “go-around.” A go-around is a standard safety procedure in which the pilots abort the landing and initiate a climb to circle around for another landing attempt. This maneuver is typically performed when the aircraft is not properly aligned with the runway, is approaching at an excessive speed, or when other unsafe conditions are detected.

According to the experts who reviewed the transcript, the pilots of Flight 812 appeared to have delayed their decision to initiate a go-around, possibly due to a combination of factors, including overconfidence, a desire to complete the landing, or a misjudgment of the remaining runway length.
