Pending completion of PHMSA and FAA's evaluation of the fire hazards posed by lithium batteries in an air transportation environment, notify the International Civil Aviation Organization's Dangerous Goods Panel about the circumstances of the fire in the Northwest Airlines cargo facility at the Los Angeles International Airport on April 28, 1999. Also pending completion of the evaluation of the fire hazards posed by lithium batteries in an air transportation environment, initiate action through the Dangerous Goods Panel to revise the Technical Instruction for the Safety Transportation of Dangerous Goods by Air to prohibit the transportation of lithium batteries on passenger-carrying aircraft.
