The verdict

Lisi Aerospace runs at 49% of its industry's injury rate - far safer than the typical Aircraft assemblies, subassemblies, and parts (except engines) manufacturing workplace, earning a grade A.

Lisi Aerospace: 1.6 TCR = 49% of Aircraft assemblies, subassemblies, and parts (except engines) manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Lisi Aerospace safety composite

Lisi Aerospace scores strongest on dart rate (safer than 58% 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).

Lisi Aerospace has more employees than the Aircraft assemblies, subassemblies, and median and a lower injury rate than the industry's median TCR of 1.9. 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.
