Ever wondered what happens during an engine change? 🔧 🤔 Swipe to see more. 🧐 For lowering and raising the engine we use the bootstrap system. This gets attached to the front and the rear of the pylon, which after loosening the eight engine bolts supports the weight of the engine. When installing a fully prepared engine, the engine change can be done overnight. Did you know that the PW1524G engine from the Airbus A220 aircraft shown above weighs over two tons? 😮 Best, @lx.aviation #flyswiss #flyswisscrew #aircraftmaintenance #aircraftmechanic #hangar #engine #a220 #airbus
