In 2024, Austin's public transit authority faced an average of one breakdown every 8,000 miles across its 300-bus fleet. Mechanics were overwhelmed by reactive repairs, and service reliability was slipping. By installing vibration sensors on wheel bearings, oil analysis ports on transmissions, and a machine-learning platform that predicted failures 48 hours in advance, the fleet's mean time between breakdowns more than tripled to 25,000 miles. Unscheduled maintenance dropped by 60 percent, saving $2.3 million in parts and overtime in the first year. This episode walks through the sensor deployment, the data pipeline that turned raw accelerometer readings into repair orders, and the cultural shift from 'fix when broken' to 'predict and prevent.' Lucas and Luna also explore a higher bar for predictive maintenance: the FAA's mandate for real-time health monitoring in next-generation aircraft engines.
