Key Takeaways:

Aircraft alternators experience diverse failure modes, ranging from mechanical issues like improper mounting, case separation, seizing, or internal damage to electrical problems such as open fields or shorted regulators.
Many reported failures occurred in-flight, sometimes prematurely after low operating hours, and frequently led to secondary damage like melted belts, fried circuit breakers, or damaged voltage regulators.
