Class Code 7403
Aircraft Operation – Scheduled – All Others
Class Code 7403 covers scheduled aircraft operations for operators not separately classified by other WCIRB codes — primarily employees who fly and staff scheduled flights. The approved California pure premium rate for September 1, 2026 is $6.002 per $100 of payroll. Understanding this code helps aviation employers assign payroll correctly, manage exposures, and control workers' comp costs.
What Class Code 7403 Covers
This classification applies to employees directly involved in the operation of scheduled flights operated by carriers that fall into the WCIRB "All Others" category — for example regional or commuter air carriers, scheduled air tour services, and scheduled cargo services that don’t have a separate airline classification. It covers in-flight operating personnel whose primary duties are to operate or manage a scheduled aircraft in revenue service: pilots, co-pilots, flight engineers and cabin crew assigned to scheduled trips. Ground activities such as maintenance, repair, hangar work, fueling, baggage handling and ticketing are typically excluded and are classified under separate WCIRB codes. The code distinguishes scheduled flight operations (set routes/timetables) from unscheduled charter or on-demand services, which may be classified differently.
Who It Applies To
- Pilots and co‑pilots working scheduled passenger or cargo routes for regional/commuter carriers
- Flight engineers and relief flight crew assigned to scheduled flights
- Flight attendants and cabin personnel on scheduled services operated by smaller carriers
- Operators of scheduled air tour services that sell seats on published departure times
- Scheduled cargo carriers operating regular pickup/delivery routes (non‑major airline)
Common Job Duties
- Preflight planning and aircraft performance calculations for scheduled legs
- Operating aircraft controls and avionics during scheduled passenger or cargo flights
- Communicating with air traffic control, dispatch and company operations for scheduled routings
- Conducting in‑flight safety procedures, passenger briefings and emergency responses
- Completing flight logs, dispatch paperwork and regulatory reporting for scheduled flights
- Performing preflight walk‑around and basic on‑aircraft inspections required before scheduled departures
Common Injury Risks
Understanding the $6.002 Rate
The pure premium rate of $6.002 per $100 of payroll is the actuarial charge that reflects expected claim costs for this class before insurer loadings. To calculate the pure premium portion, multiply payroll assigned to Class 7403 (in hundreds) by $6.002. The final premium an employer pays will also reflect experience modification, insurer expense loadings, policy fees, any schedule ratings and the accuracy of payroll classification.
Cal/OSHA Compliance Requirements
Flight operations are primarily regulated by the FAA for in‑flight safety, but Cal/OSHA requirements apply to workplace safety when work is performed in California — for example hangar operations, preflight inspections, fueling, training and other on‑ground activities. California employers must maintain hazard communication for fuels/chemicals, implement hearing conservation for engine noise exposure, provide fall protection and PPE for aircraft access, and comply with recordkeeping and injury reporting obligations under Cal/OSHA when work occurs in the state.
How Key HR Helps Employers Under Class Code 7403
A PEO like Key HR can help aviation employers ensure payroll is correctly allocated to Class 7403, implement targeted loss‑control programs (crew resource management, turbulence handling, preflight checklists), and manage claims and return‑to‑work to lower experience modification. Key HR also coordinates OSHA/FAA training compliance, centralized claims advocacy, and regular loss control audits to reduce frequency and severity of claims.
Get a QuoteFrequently Asked Questions
Are ground crews and maintenance technicians included in Class 7403?
No. Class 7403 is specific to scheduled aircraft operating personnel (pilots, flight engineers, cabin crew) on scheduled flights. Maintenance, repair, fueling, baggage handling and other ground functions are normally assigned to separate WCIRB class codes.
How can my company lower workers' comp costs for scheduled flight crews?
Focus on injury prevention (CRM and turbulence protocols), documented return‑to‑work programs, accurate payroll classification, and proactive claims handling. Improving safety training, fatigue risk management and post‑incident investigations reduces claim severity and your experience modification over time.
Which rules apply: FAA or Cal/OSHA?
Both. FAA regulations govern in‑flight operation and certification; Cal/OSHA applies to workplace safety in California for on‑ground activities and employee protection. Employers operating in California must comply with applicable FAA standards and meet Cal/OSHA requirements for ground safety, training, PPE and recordkeeping.
