Master switch-on. Mixture-rich. Fuel pump-on until pressure registers, then off. Ignition key-start. Silence. Fortunately that result is rare. Almost invariably, when we turn the ignition key to start or hit a starter button on a piston-engine airplane, the starter engages and the prop swings with vigor. Over the past 20 years, new technology has made aircraft starters remarkably reliable-the newer ones should last beyond the engines TBO, if not abused. So, when there’s a big silence on hitting the start switch, the chances are that the problem is not with the starter itself. Nevertheless, the time does come when the starter slips its mortal coil and must either be replaced, rebuilt or overhauled. Well talk about how to make your starter last, a little about troubleshooting problems and what options are available when it gives up the ghost.
