Key Takeaways:

Aircraft engines experienced a variety of piston failures, including broken skirts, rings, crowns, and preignition, often leading to severe damage and engine removal.
Common symptoms of these failures included metal contamination in the oil system, rough engine operation, vibration, and loss of compression.
Many piston failures occurred at relatively low engine total times across different aircraft models, with one specific aircraft experiencing recurring piston skirt issues across multiple engines.
