Key Takeaways:

Numerous aircraft incidents across Cessna, Piper, and Diamond models reported failures of alternator and air conditioning belts.
Common belt issues included shearing, breaking, stretching, and tearing, often occurring at relatively low part total times.
These failures led to problems such as loss of electrical power, burning odors/smoke in the cockpit, and in some cases, engine operational issues, with causes including incorrect installation, manufacturing defects, and environmental factors.
