About The Author
Aircraft Accident Investigation is a specialised process requiring vast experience and expertise gained through attending various investigations in resolving probable cause of aircraft accidents. Addressing effectively the above requirement, this book develops a stepwise systematic approach to successfully and meaningfully deal with the process of investigation of aircraft accidents. The book aims at identifying the primary reason of failure and suggests remedial measures to thwart recurrence of similar accidents in future. The basics of aero-engine and its systems, various types of failure of engine components and subsystems, analysis of flight data recorder, etc. have been clearly dealt with. The aim of the book is to instil confidence in neophytes entering into the field of aircraft accident investigation and to sharpen the skills of professionals in the field. One key feature of the book is that instead of fabricated hypothetical cases, only actual cases have been taken up for the discussion of the investigative procedure and its analysis for the probable cause of accident.

Mr C Jaganathan obtained his graduation in Mathematics from University of Madras, followed by a graduation in Aeronautical Engineering from Madras Institute of Technology. He obtained his Master's degree in Aeronautical Engineering from Indian Institute of Technology, Kharagpur. Initially he worked for four years as Scientist 'B' at DRDL, Hyderabad. Subsequently, he was posted to RCMA at Koraput and Bangalore, and served for 25 years as airworthiness engineer ensuring certification requirements of both Russian and Western power plants built at the engine division at HAL, Koraput and Bangalore. Presently, he is Additional Director, Gas Turbine Research Establishment, Bangalore, looking after the assembly and testing of engines, engine subsystems like main and afterburner fuel system, variable guide vane mechanisms, exhaust nozzle control systems and certification of ab initio power plants, and the like. As of now he has retired from DRDO service. Gp Capt S K Jain is a Mechanical Engineering graduate from SGSITS, Indore, and holds a Master's degree in Aerospace Engineering from Indian Institute of Technology, Chennai. He specializes in the field of aerospace propulsion and has vast experience in the repair and overhaul of engines, and has been instrumental in the indigenous development of many repair and reclamation technologies. While at the Gas Turbine Research Establishment, Bangalore, he overviewed the progress of the Kaveri Project and was involved in the design and development of military aero engine for Light Combat Aircraft. He is presently commanding a Base Repair Depot of IAF involved in the repair and overhaul of aero engines powering military aircraft.
