Answer
The Military Aviation Authority (MAA) regulates military airworthiness risk within the policy framework set by the Secretary of State for Defence in the Health, Safety & Environmental Protection statement. The MAA’s Regulatory Articles and Defence Standards require that aircraft designs minimise the risk of cockpit or cabin air contamination by engine oil, lubricants, fuel vapours, or combustion products. Any residual risk must be managed within the aircraft’s safety case to ensure aircrew safety and operational capability.
