What is the primary focus of the Occupational Safety and Health Administration (OSHA) in the aviation industry?

The primary focus of the Occupational Safety and Health Administration (OSHA) in the aviation industry is to ensure that workplace safety and health regulations are met. OSHA's mission is to promote safe and healthy working conditions for all workers by establishing and enforcing standards and providing training, education, and assistance. In aviation, this translates to ensuring that the environments where airline employees work – including maintenance facilities, hangars, and airports – adhere to safety regulations that protect workers from hazards.

The other options involve areas that are typically governed by different authorities or regulations. For example, the regulation of aircraft design standards falls under the purview of the Federal Aviation Administration (FAA), which focuses on aircraft safety and the certification of aviation products. Air traffic control operations are also managed by the FAA, which oversees the nation's air traffic control system to ensure the safe and orderly flow of air traffic. Lastly, setting standards for pilot training programs is again the responsibility of the FAA, which establishes requirements for pilot certification and ongoing training to ensure competency and safety in flight operations.
