The verdict

Aerofab runs at 130% of its industry's injury rate - more dangerous than the typical Developing and producing prototypes for aircraft engines and engine parts workplace, earning a grade D.

Aerofab: 4.3 TCR = 130% of Developing and producing prototypes for aircraft engines and engine parts BLS 3.3 · 2y Form 300A (see methodology below)

Aerofab safety composite

Aerofab scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on total case rate (tcr) (safer than 13%), 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).

Where Aerofab falls in its industry

366 Developing and producing proto establishments

Safer than 13% of graded establishments in this industry, whose median TCR is 1.6.

Grade D

More dangerous than peersSafer than peers

Narrower to Indiana alone (the establishments it most directly competes with for workers and contracts): ranked #23 safest of 24 Developing and producing proto employers in Indiana.

Aerofab (159 employees, TCR 4.3) among 29 same-industry peers, split at the industry median of 155 employees and a TCR of 1.6

Aerofab has more employees than the Developing and producing prototypes for median and a higher injury rate than the industry's median TCR of 1.6. 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.
