Overview

• Air India flight AI117 (VT-ANO) from Amritsar reported automatic Ram Air Turbine deployment around 400–500 feet on final approach to Birmingham on October 4 and landed safely with electrical and hydraulic parameters reported normal.
• The aircraft was grounded in Birmingham and its return leg AI114 was cancelled, then Boeing-recommended checks for uncommanded RAT activation found no discrepancies and the DGCA said the jet was released for service pending the probe.
• India’s aviation regulator has opened a detailed investigation, assigned a Directorate of Air Safety officer, and noted Boeing’s Fleet Team Digest summarising prior similar occurrences.
• The Federation of Indian Pilots urged comprehensive inspections of 787 electrical systems across India and cited Aircraft Health Monitoring data indicating a Bus Power Control Unit fault that may have triggered the deployment.
• The incident is the second RAT-related event on an Indian 787 since the June 12 AI171 crash now under AAIB investigation, with the final report still awaited.
