The FAA has amended its regulations to facilitate certification of Part 25 air transport aircraft, cabin-pressurization systems, and oxygen-dispensing equipment for operation at high-elevation airports—namely those above 8,000 feet msl.

Current regulations require that the cabin pressure altitude on transport airplanes remain at or below 8,000 feet in normal operating conditions. The new amendments, effective on July 17, eliminate a burden on industry by removing a rule that calls for applicants to meet specialized design-modification requirements under an equivalent level of safety finding and file a petition for exemption when seeking to operate above 8,000 feet.
