The verdict

Headquarters runs at 176% of its industry's injury rate - more dangerous than the typical Aircraft manufacturing workplace, earning a grade D.

Headquarters: 5.8 TCR = 176% of Aircraft manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Headquarters safety composite

Headquarters scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on total case rate (tcr) (safer than 11%), 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).

Headquarters has more employees than the Aircraft manufacturing median and a higher injury rate than the industry's median TCR of 1.7. 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.
