Safety Insights for Learjet Inc.

Learjet Inc. operates an establishment with approximately 1,406 full-time equivalent workers in WICHITA, KS, classified under the Aircraft manufacturing industry (NAICS 336411). Across 3 years of mandatory OSHA Injury Tracking Application (ITA) reporting, this employer has accumulated 56 recordable injuries, 0 occupational illnesses, and 0 workplace fatalities. The average Total Case Rate (TCR) of 1.3 injuries per 100 full-time workers per year provides the anchor metric for the A letter grade (Excellent Safety Record).

Benchmarked against the Bureau of Labor Statistics industry average of 3.3 for Aircraft manufacturing, Learjet Inc.'s workforce experiences 40% 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 below the benchmark signals that controls, training, or automation may be outperforming peers.

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 3 reporting cycles points to systemic hazard exposure. Readers evaluating Learjet Inc. 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.

DART Rate — Transparent Calculation (2019)

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.

5 DART incidents × 200,000 ÷ 2,512,340 hours worked = 0.40 DART
