The verdict

Sterling Engineering runs at 61% of its industry's injury rate - safer than the typical Aircraft propellers and parts manufacturing workplace, earning a grade B.

Sterling Engineering: 2.0 TCR = 61% of Aircraft propellers and parts manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Sterling Engineering safety composite

Sterling Engineering scores strongest on dart rate (safer than 80% of same-industry peers) and weakest on total case rate (tcr) (safer than 46%), 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).
