The verdict

LISI Aerospace runs at 115% of its industry's injury rate - about level with the typical Aircraft assemblies, subassemblies, and parts (except engines) manufacturing workplace, earning a grade C.

LISI Aerospace: 3.8 TCR = 115% of Aircraft assemblies, subassemblies, and parts (except engines) manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

LISI Aerospace safety composite

LISI Aerospace scores strongest on fatalities (safer than 50% 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).

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%).

Rising injury rate

LISI Aerospace: 2.8 → 4.7 TCR

Peak year 2018 @ 4.8 TCR · DART/TCR 0.57× in 2020

LISI Aerospace's TCR rose 1.9 from 2.8 in 2017 to 4.7 in 2020. Peak filing year was 2018 at 4.8 TCR. In 2020, DART was 0.57× this establishment's average TCR (severity share of cases).

Where LISI Aerospace falls in its industry

650 Aircraft assemblies, subassemb establishments

Safer than 20% of graded establishments in this industry, whose median TCR is 1.9.

Grade C

More dangerous than peersSafer than peers

Narrower to California alone (the establishments it most directly competes with for workers and contracts): ranked #76 safest of 104 Aircraft assemblies, subassemb employers in California.

LISI Aerospace (806 employees, TCR 3.8) among 29 same-industry peers, split at the industry median of 130 employees and a TCR of 1.9

LISI Aerospace has more 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.
