Abstract : The continued fire endurance of fire-blocked aircraft seat cushions after service wear and tear was evaluated based on in-service examinations performed on commercial aircraft and sample testing of donated cushions per the oil burner test contained in Part 25, Appendix F, Pan II of the Federal Aviation Regulations. A total of 176 examinations took place onboard aircraft to evaluate the condition of the in-service aircraft seats. A comparison was made between the observed conditions of the in-service seat cushions and the 38 used seat cushion sets that were donated for this project. The comparison indicated that the donated used aircraft cushion sets were representative of actual in-service conditions. The donated cushion sets were then evaluated for continued fire worthiness with the aircraft cushion oil burner test. Eight pairs were retained in stock condition and the remaining 30 pairs were altered to a 'modified' test configuration. The test results included the weight loss profile for each cushion set burnt. The test results indicated that there were no significant fire endurance problems with the fire-blocking materials that were composed of Keviar, Nomex, and/or polybenzimidazole (PBI) components.
