Condition-Based Maintenance in Aviation: The History, The Business and The Technology describes the history and practice of Condition-Based Maintenance (CBM) systems by showcasing ten technical papers from the archives of SAE International, stretching from the dawn of the jet age down to the present times. By scientifically understanding how different components degrade during operations, it is possible to schedule inspections, repairs, and overhauls at appropriate intervals so that any incipient failure can be detected well in advance. Today, this includes more sensors and analytics so that periodic inspections are replaced by automated "continuous" inspections, and analytical methods that detect imminent failures and predict degradation issues more economically and efficiently. Similar concepts are also being developed for delivering prognostics functions, such as tracking of remaining useful life (RUL) of life-limited parts in aircraft engines. The discipline within CBM that deals with this is called prognostics and health management (PHM), which covers all aspects of diagnostics and prognostics, including modeling of systems and subsystems, sensing, data transmission, storage and retrieval, analytical methods, and decision making. Traditionally, nondestructive testing (NDT) methods have been employed during the major airplane checks to assess structural damage. These techniques are enhanced with in- situ sensing techniques that can continuously monitor aircraft structures and report on their health. The move to condition-based assessment of maintenance needs to be balanced by the assurance that safety is not compromised, that initial cost of new equipment is amortized by the savings, and that regulatory authorities are on board with any modifications to the planned maintenance schedule. The trend is clearly to include more CBM functions into Maintenance, Repair and Overhaul (MRO) processes so better cost control can be achieved without ever comprising passenger safety.

On the night of 4 July 1943, transport aircraft Liberator AL523 took off from Gibraltar’s North Front tarmac and within moments crashed into the sea with only one survivor, the pilot. The commander-in-chief of the Polish army and prime minister of the Polish government-in-exile, General W?adys?aw Sikorski, was dead. Rumours as to the cause of the crash abounded. Was it pilot error? Was it, as officially classified, merely an accident, or was it, as the authors conclude in this riveting and meticulous study, an act of sabotage? In this extensive piece of research, Chris Wroblewski and Garth Barnard examine numerous primary sources, including the complete court of inquiry transcripts, produce detailed analysis of aircraft components and systems and unearth many little-known eyewitness accounts to give this investigation a compelling conclusion. Within the book the authors also dispel several conspiracy theories that have emerged since this catastrophe; particularly that this event was a disastrous assassination attempt with blame on the British, Soviets and Nazis. This is an exhaustive piece of investigative journalism that puts the record straight once and for all.

Introduction to Maintenance, Repair and Overhaul of Aircraft, Engines and Components brings together the basic aspects of a fundamentally important part of the aerospace industry, the one that supports the global technical efforts to keep passenger and cargo planes flying reliably and safely. Over time, aircraft components and structural parts are subject to environmental effects, such as corrosion and other types of material deterioration, wear and fatigue. Such parts could fail in service and affect the safe operation of the aircraft if the degradation were not detected and addressed in time. Regular planned maintenance supports the current and future value of the aircraft by minimizing the physical decline of the aircraft and engines throughout its life. Introduction to Maintenance, Repair and Overhaul of Aircraft, Engines and Components was written by the industry veteran, Shevantha K. Weerasekera, an aerospace engineer with 20+ years of aircraft maintenance experience, who currently leads the engineering team of a major technical enterprise in the field.
