The verdict

ZeroAvia runs at 54% of its industry's injury rate - safer than the typical Aeronautical systems and instruments manufacturing workplace, earning a grade B.

ZeroAvia: 1.8 TCR = 54% of Aeronautical systems and instruments manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

ZeroAvia safety composite

ZeroAvia scores strongest on dart rate (safer than 75% of same-industry peers) and weakest on total case rate (tcr) (safer than 20%), 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).

ZeroAvia (25 employees, TCR 1.8) among 29 same-industry peers, split at the industry median of 207 employees and a TCR of 0.7

ZeroAvia has fewer employees than the Aeronautical systems and instruments man median and a higher injury rate than the industry's median TCR of 0.7. 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.
