CAA latest update

The CAA will assess and, where appropriate, amend the design and installation requirements for lithium-ion main batteries located in cabin areas of general aviation (GA) aircraft with a view to minimising the hazard they pose to aircraft occupants. Although the safety recommendation scope is limited to non-Part 21 aircraft, the CAA has since become aware of some Part 21 GA aircraft that have a similar battery configuration; the assessment will therefore include Part 21 and non-Part 21 GA aircraft.
