  1. Incidents and Recalls • FAA records indicate consistent increase in lithium battery incidents • CPSC recalled more than 9 million laptop computers worldwide

  2. DOT & Industry Response • PHMSA safety advisory • ALPA safety alert • FAA information for operators • PHMSA final rule on lithium batteries

  3. Remaining Issues • Incident reporting • Analysis of specific risks • Remaining exemptions • Involvement in in-flight fires

  4. Incident Reporting • FAA maintains record of reported battery incidents • Final rule on lithium batteries did not eliminate exemption • Unlikely that FAA record provides accurate account

  5. Analysis of Specific Risks • Secondary batteries • Failure modes not well understood • Proper evaluation not always performed • Failed batteries prematurely disposed • Primary batteries • Impact of clustering not yet considered

  6. Remaining Exemptions • Small secondary batteries • Exempt from packaging and identification requirements • Cargo shipments permitted on cargo and passenger flights

  7. Involvement in In-Flight Fires • Halon is effective in suppressing secondary battery fires • Suppression systems not yet required • Halon is not effective in suppressing primary battery fires • Additional safety measures needed
