Safety Insights for Hartzell Propeller Composite
Hartzell Propeller Composite operates an establishment with approximately 37 full-time equivalent workers in PIQUA, OH, classified under the Aircraft propellers and parts manufacturing industry (NAICS 336413). Across 7 years of mandatory OSHA Injury Tracking Application (ITA) reporting, this employer has accumulated 6 recordable injuries, 4 occupational illnesses, and 0 workplace fatalities. The average Total Case Rate (TCR) of 3.5 injuries per 100 full-time workers per year provides the anchor metric for the C letter grade (Average Safety Record).
Benchmarked against the Bureau of Labor Statistics industry average of 3.3 for Aircraft propellers and parts manufacturing, Hartzell Propeller Composite's workforce experiences 106% of the typical injury burden. This ratio matters because TCR already normalizes for hours worked, a 200,000-hour exposure base equals roughly 100 full-time workers, so establishments with very different headcounts can be compared directly. A TCR above the benchmark flags a higher-than-typical risk profile for jobseekers, insurers, and enforcement agencies to examine.
Multi-year trend analysis is the single most reliable signal here: a one-year spike could reflect a single severe event, whereas sustained elevation across 7 reporting cycles points to systemic hazard exposure. Readers evaluating Hartzell Propeller Composite as an employer, contractor, investment, or regulatory target should examine the yearly DART rate (days away, restricted, or transferred), the fatality count of 0, and any year-over-year deterioration shown in the table below. All figures come directly from employer-submitted OSHA Form 300A summaries, there is no modeling, estimation, or third-party adjustment layered on top of the government data.
Verify This Employer with OSHA
All injury, illness, and fatality figures on this page are sourced from Hartzell Propeller Composite's own mandatory OSHA Form 300A summaries. Cross-check the underlying establishment record directly against the federal source, name, NAICS classification, recordable case totals, and inspection history are all searchable on OSHA's Establishment-Specific Injury and Illness Data system.

DART Rate, Transparent Calculation (2023)
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.
1 DART incidents × 200,000 ÷ 157,324 hours worked = 1.27 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping

What this grade means for you
Use this grade as a relative read on Hartzell Propeller Composite's reported OSHA injury record versus its Aircraft propellers and parts manufacturing peers, not a verdict on whether any single site is safe today.
- At 106% of the Aircraft propellers and parts manufacturing benchmark, Hartzell Propeller Composite reports more injuries than typical peers, ask specifically how the employer is reducing them. Know your rights
- Judge this record against the wider Aircraft propellers and parts manufacturing sector, where injury rates vary widely, before comparing it in isolation. See the industry
- Grades reflect 2016–2024 filings; check the latest establishment record straight from OSHA, or look up a different employer. Look up another
Safety grades reflect employers' self-reported OSHA Form 300A filings from 2016 to 2024 and can lag current conditions. A grade is not a guarantee that any specific workplace is safe or unsafe today. See our methodology and disclaimer.
