The U.S. NTSB has recommended that the FAA require that all cargo airplanes operating under Part 121 install fire suppression systems. This recommendation is a result of the Board`s
investigation of a UPS DC-8 cargo fire in Philadelphia last year.
As a result of its investigation, the Safety Board made recommendations in the following areas including: guidance and checklists relating to in-flight fire and smoke, certification requirements for smoke and fire detection system tests, fire suppression system requirements, aircraft rescue and firefighting training, cargo airplane emergency exit requirements, hazardous materials information and dissemination procedures, and transport of lithium batteries on board aircraft.
