Northstar Aerospace (Phoenix) 401 Building: 2.0 TCR = 61% of Aircraft assemblies, subassemblies, and parts (except engines) manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Northstar Aerospace (Phoenix) 401 Building safety composite

Northstar Aerospace (Phoenix) 401 Building scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 28%), blended into one 0-100 breakdown against same-industry peers.
