The verdict

MB Aerospace runs at 83% of its industry's injury rate - about level with the typical Aircraft engine and engine parts (except carburetors, pistons, piston rings, valves) manufacturing workplace, earning a grade C.

MB Aerospace: 2.7 TCR = 83% of Aircraft engine and engine parts (except carburetors, pistons, piston rings, valves) manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

MB Aerospace safety composite

MB Aerospace scores strongest on dart rate (safer than 81% of same-industry peers) and weakest on total case rate (tcr) (safer than 28%), 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).
