The verdict

Superior Aerospace runs at 89% of its industry's injury rate - about level with the typical Boring, drilling, and milling machine combinations, metalworking, manufacturing workplace, earning a grade C.

Superior Aerospace: 2.9 TCR = 89% of Boring, drilling, and milling machine combinations, metalworking, manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Superior Aerospace safety composite

Superior Aerospace scores strongest on total case rate (tcr) (safer than 56% of same-industry peers) and weakest on dart rate (safer than 27%), 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).

Superior Aerospace (46 employees, TCR 2.9) among 29 same-industry peers, split at the industry median of 55 employees and a TCR of 3.4

Superior Aerospace has fewer employees than the Boring, drilling, and milling machine co median and a lower injury rate than the industry's median TCR of 3.4. Workforce size and injury rate do not always move together within the same industry -- some of its smaller peers run higher rates than its larger ones, and vice versa.
