The verdict

MACRO - Discovery Drive runs at 79% of its industry's injury rate - safer than the typical Aircraft assemblies, subassemblies, and parts (except engines) manufacturing workplace, earning a grade B.

MACRO - Discovery Drive: 2.6 TCR = 79% of Aircraft assemblies, subassemblies, and parts (except engines) manufacturing BLS 3.3 · 5y Form 300A (see methodology below)

MACRO - Discovery Drive safety composite

MACRO - Discovery Drive scores strongest on dart rate (safer than 80% of same-industry peers) and weakest on total case rate (tcr) (safer than 35%), 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).

Benchmarked live against every credibly-rated employer in the same NAICS industry code in the current OSHA extract (a segment must have at least 8 rated peers to benchmark). Not a legal or compliance determination; PlainSafetyScore's own weighting (TCR 40%, DART 35%, fatalities 25%).

Where MACRO - Discovery Drive falls in its industry

650 Aircraft assemblies, subassemb establishments

Safer than 35% of graded establishments in this industry, whose median TCR is 1.9.

Grade B

More dangerous than peersSafer than peers

Narrower to Alabama alone (the establishments it most directly competes with for workers and contracts): ranked #10 safest of 13 Aircraft assemblies, subassemb employers in Alabama.

MACRO - Discovery Drive (43 employees, TCR 2.6) among 29 same-industry peers, split at the industry median of 130 employees and a TCR of 1.9

MACRO - Discovery Drive has fewer 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.
