| 摘要： | The National Transportation Safety Board has recommended that fire suppression systems be installed in the cargo compartments of all cargo airplanes operating under 14 CFR Part 121. Currently, Class E cargo compartments, which are the primary cargo compartment type used in US cargo airplanes, do not require fire suppression systems. In response to this recommendation, FAA has requested that a cost/benefit analysis be carried out relating to the installation of on-board fire detection and extinguishment systems in cargo airplanes. This report contains the results of this analysis and a description of the methodology used. The analysis assessed whether fire suppression systems, fitted to the cargo bays of cargo airplanes, type certificated to FAR Part 25 and operating under FAR Part 121, are likely to be cost beneficial. Potential benefits will result from a reduction in Injuries (Fatal and Serious) to personnel, a reduction in the damage incurred to the aircraft and its cargo, and a reduction in the damage that might be incurred to property on the ground. Potential costs are those that might be incurred from the installation and operation of fire suppression systems. A mathematical model has been developed to assess the benefit. The model utilizes statistical distributions derived from data on in-service airplanes and accident information. Cost assessments were made for modifying cargo aircraft to the new Type F Cargo Compartment being considered for combi aircraft. These cost assessments were based on the installation of a Halon type fire suppression system together with suitable cargo compartment liners. The data used in the cost assessment was based on that contained in the ARAC document relating to main deck class B cargo compartments. The results of the study suggest that crew injuries (Fatal and Serious combined) and the loss of the aircraft and cargo in freighter fire accidents are likely to be a significant factor in the prediction of benefit. Collateral ground damage does not appear to contribute significantly to the prediction of benefit. It is concluded that Halon fire suppression systems, or alternatives that are likely to be developed for below floor cargo compartments, are unlikely to be cost beneficial for the cargo compartments of cargo aircraft. Fire suppression systems, of the kind currently being considered for the cargo compartments of combi aircraft, may prove to be cost beneficial, particularly on larger cargo aircraft. |
