The verdict

NWTL runs at 57% of its industry's injury rate - safer than the typical Aircraft maintenance and repair services (except factory conversion, factory overhaul, factory rebuilding) workplace, earning a grade B.

NWTL: 2.6 TCR = 57% of Aircraft maintenance and repair services (except factory conversion, factory overhaul, factory rebuilding) BLS 4.5 · 3y Form 300A (see methodology below)

NWTL safety composite

NWTL scores strongest on total case rate (tcr) (safer than 60% of same-industry peers) and weakest on dart rate (safer than 41%), 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).

NWTL has more employees than the Aircraft maintenance and repair services median and a lower injury rate than the industry's median TCR of 3.2. 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.
