The verdict

MDW - Maintenance runs at 184% of its industry's injury rate - more dangerous than the typical Scheduled Passenger Air Transportation workplace, earning a grade D.

MDW - Maintenance: 8.3 TCR = 184% of Scheduled Passenger Air Transportation BLS 4.5 · 6y Form 300A (see methodology below)

MDW - Maintenance safety composite

MDW - Maintenance scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on total case rate (tcr) (safer than 36%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
