The verdict

L3Harris Aviation Products runs at 12% of its industry's injury rate - far safer than the typical Aircraft flight instruments (except engine instruments) manufacturing workplace, earning a grade A.

L3Harris Aviation Products: 0.4 TCR = 12% of Aircraft flight instruments (except engine instruments) manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

L3Harris Aviation Products safety composite

L3Harris Aviation Products scores strongest on total case rate (tcr) (safer than 70% of same-industry peers) and weakest on dart rate (safer than 22%), 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).
