The verdict

Asco Aerospace USA runs at 34% of its industry's injury rate - far safer than the typical Aircraft assemblies, subassemblies, and parts (except engines) manufacturing workplace, earning a grade A.

Asco Aerospace USA: 1.1 TCR = 34% of Aircraft assemblies, subassemblies, and parts (except engines) manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

Asco Aerospace USA safety composite

Asco Aerospace USA scores strongest on dart rate (safer than 80% of same-industry peers) and weakest on fatalities (safer than 50%), 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).
