Trend analysis for Arnprior Aerospace Portland Inc.
Between 2016 and 2024, Arnprior Aerospace Portland Inc.'s Total Case Rate worsened from 2.7 to 6.2 recordable injuries per 100 full-time workers, a 132% increase across 8 years of OSHA reporting.
The safest year on record was 2017, at a TCR of 0.8, while 2024 saw the highest rate, at 6.2, a spread of 5.3 points between the best and worst reporting years. That's a wide swing relative to the establishment's overall rate, worth checking the year-by-year table below for whether a single severe year is driving the average, rather than a sustained trend.
Summed across those 3 reporting years, Arnprior Aerospace Portland Inc. recorded 10 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 3-year trend above alongside establishment size, since a larger workforce naturally accumulates more raw incidents even at a lower per-100-worker rate.

DART Rate, Transparent Calculation (2024)
What is the DART rate formula?
DART (Days Away, Restricted, or Transferred) is computed by OSHA as incidents × 200,000 ÷ hours worked. The 200,000-hour denominator equals roughly 100 full-time workers, which lets establishments of very different sizes be compared directly.
6 DART incidents × 200,000 ÷ 226,720 hours worked = 5.29 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
