Regulatory Action Targets Potential Lightning Strike Explosion Risk
The Federal Aviation Administration (FAA) has issued an airworthiness directive requiring inspections of certain Boeing 787 Dreamliners due to concerns over potential fuel tank explosions during lightning strikes. The directive, which applies to 60 US-registered aircraft, stems from incomplete or unverifiable manufacturing checks of fuel tank sealant. Operators must conduct detailed inspections and address any defects found, with estimated costs of $2,890 per aircraft. The FAA’s action follows a proposal published earlier this year and takes effect December 7, 2026. This development was first reported by AeroTime.
