Aviation: Lithium-ion Batteries

Question: To ask the Secretary of State for Transport, what recent discussions her Department has had with the Civil Aviation Authority on safety incidents involving lithium batteries on commercial flights.

Answer: Department for Transport (DfT) officials work closely with and regularly meet the Civil Aviation Authority (CAA) to monitor and discuss the risk of lithium batteries incidents, alongside other safety risks. The Dangerous Goods Governance Board meets quarterly to manage the joint DfT/CAA Lithium Batteries project which aims to reduce the risk posed by the carriage of undeclared lithium batteries aboard commercial aircraft to a level as low as reasonably practicable. In addition to the reduction of risk, the project provides assurance to the State Safety Board, which meets every 6 months, that the UK’s exposure to this safety risk is monitored, prioritised, responded to and effectively mitigated. There are also multiple other forums where DfT officials and the CAA discuss safety risks formally and informally, including lithium batteries.
