The verdict

Ferra Aerospace runs at 105% of its industry's injury rate - about level with the typical Aircraft assemblies, subassemblies, and parts (except engines) manufacturing workplace, earning a grade C.

Ferra Aerospace: 3.5 TCR = 105% of Aircraft assemblies, subassemblies, and parts (except engines) manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Ferra Aerospace safety composite

Ferra Aerospace scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 21%), 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).

Where Ferra Aerospace falls in its industry

650 Aircraft assemblies, subassemb establishments

Safer than 23% of graded establishments in this industry, whose median TCR is 1.9.

Grade C

More dangerous than peersSafer than peers

Narrower to Oklahoma alone (the establishments it most directly competes with for workers and contracts): ranked #29 safest of 31 Aircraft assemblies, subassemb employers in Oklahoma.

Ferra Aerospace (48 employees, TCR 3.5) among 29 same-industry peers, split at the industry median of 130 employees and a TCR of 1.9

Ferra Aerospace has fewer employees than the Aircraft assemblies, subassemblies, and median and a higher 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.
