India’s Ministry of Civil Aviation says the investigation into the AI-171 aircraft probe has entered its final stage. According to the ministry, a detailed examination focuses on the aircraft’s fuel control switch, including the structural integrity of its locking detents. The ministry states that the inspection “found no abnormality,” indicating no fault in the fuel switch based on the checks described.

The ministry’s update reflects the investigators’ emphasis on verifying whether the fuel control mechanism could have contributed to the incident under review. The statement does not provide additional findings on other components or broader conclusions from the ongoing probe, and it does not specify when the final report will be released.

With the probe now in its concluding phase, the next steps would be expected to involve compiling and assessing all investigation inputs. The ministry’s current communication highlights the result of the fuel switch examination as one element of the broader inquiry.
