The verdict

MDW runs at 180% of its industry's injury rate - more dangerous than the typical Aviation Maintenance and Repair Services workplace, earning a grade D.

MDW: 8.1 TCR = 180% of Aviation Maintenance and Repair Services BLS 4.5 · 9y Form 300A (see methodology below)

MDW safety composite

MDW scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 6%), 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).
