The investigation will scrutinize technical records, pilot certifications, and operational logs, with potential reforms for uncontrolled airfields to be considered. New Delhi: Union Civil Aviation Minister K. Rammohan Naidu formally responded to Maharashtra Chief Minister Devendra Fadnavis on Thursday, pledging a "transparent and time-bound" federal investigation into the plane crash that killed Deputy Chief Minister Ajit Pawar and four others. The response follows a written request from Fadnavis seeking a high-level probe into the Wednesday morning disaster at Baramati Airport. The flight data recorder and cockpit voice recorder (the black box) were recovered from the charred wreckage of the Learjet 45XR and have been transported to Delhi. Call for State CooperationWhile the AAIB leads the technical investigation, Naidu emphasised that the cooperation of the Maharashtra government and local Baramati administration remains "valuable" for the inquiry.
