Reduction of Fuel Tank Flammability on Transport Category Airplanes

The information or data collection is mandatory from the DAHs as required by the FAA regulations as specified in item 1. The main purpose of the data collection is for the review by FAA oversight offices of the transport aircraft fuel tank safety level as required by the FAA regulations. The DAHs are required to provide semi-annual reliability reports. The FAA safety oversight offices have reviewed the collected data in order to assess mandatory action to correct any unsafe conditions resulting from poor reliability of the fuel tank flammability reduction means (FRM) and the resulting increased flammability of the fuel tanks on transport category airplanes. This is because high flammability fuel tanks are susceptible to catastrophic fuel tank explosions. These collected data are the fuel tank FRM component reliability reports as specified in item 1. In summary, the FAA requires the DAHs to collect and provide the fuel tank FRM component reliability results for FAA safety review. This is to ensure the fuel tank safety level meets the regulatory requirements specified in item 1.
