Design approval holders voluntarily use the flammability analysis documentation to demonstrate to their FAA Oversight Office that they are compliant with regulations by submitting semi-annual reports detailing component failures discovered during scheduled or unscheduled maintenance. The FAA safety oversight offices will use the collected data to determine if mandatory action should be initiated to correct any unsafe conditions resulting from poor reliability of the flammability reduction means (FRM) and the resulting increased flammability of the fuel tanks on transport category airplanes. High flammability fuel tanks are susceptible to catastrophic fuel tank explosions. Maintaining fuel tank FRM reliability results in the safety level intended by the adopted regulatory requirements for installation of FRM
The FAA has received reports of premature failure of components on some airplane models resulting in the need to continue the reporting requirement. However, the number of reporting-burden hours has decreased since the previous submission. The previous reporting burden was based on 5 design approval holders submitting 40 total reports per year requiring an average of 100 hours to complete each report. There are currently five design approval holders and four parts manufacturer approval holders that are subject to the reporting requirements. The necessary reporting intervals are twice per year and are based on reliability data submitted from the initial introduction to service of the FRM. The current burden is based on 9 approval holders submitting 18 total reports per year, requiring an average of 100 hours to complete each report. The use and acceptance of electronic reports is now 1s00 pedrcent.
