The verdict

Triumph Gear Systems runs at 144% of its industry's injury rate - more dangerous than the typical Aircraft assemblies, subassemblies, and parts (except engines) manufacturing workplace, earning a grade D.

Triumph Gear Systems: 4.8 TCR = 144% of Aircraft assemblies, subassemblies, and parts (except engines) manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Triumph Gear Systems safety composite

Triumph Gear Systems scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on total case rate (tcr) (safer than 14%), 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 Triumph Gear Systems falls in its industry

650 Aircraft assemblies, subassemb establishments

Safer than 14% of graded establishments in this industry, whose median TCR is 1.9.

Grade D

More dangerous than peersSafer than peers

Narrower to Michigan alone (the establishments it most directly competes with for workers and contracts): ranked #11 safest of 13 Aircraft assemblies, subassemb employers in Michigan.

Triumph Gear Systems (275 employees, TCR 4.8) among 29 same-industry peers, split at the industry median of 130 employees and a TCR of 1.9

Triumph Gear Systems has more 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.
