Effective Aug. 14, 2023, the FAA is amending its standards for Part 25 large airplane pressurized compartment loads such that partitions located adjacent to a decompression hole need not be designed to withstand a certain decompression condition. The agency said this rulemaking is necessary because, “in some cases, it is not practical to design partitions in certain airplane compartments to withstand this decompression condition if it occurs within that compartment.” The new rules allow partition failure if the certificate applicant can demonstrate such a failure would not “interfere with continued safe flight and landing.” The requirement is essentially unchanged from a notice of proposed rulemaking published in 2019 and the suggested changes made by those organizations that commented.
