The verdict

Ada Assy runs at 121% of its industry's injury rate - more dangerous than the typical Aircraft manufacturing workplace, earning a grade D.

Ada Assy: 4.0 TCR = 121% of Aircraft manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Ada Assy safety composite

Ada Assy scores strongest on dart rate (safer than 82% of same-industry peers) and weakest on total case rate (tcr) (safer than 18%), 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).
