What happened
The FAA issued an airworthiness directive requiring inspections and adhesion tests of sealant installations on certain Boeing 787-8, 787-9 and 787-10 aircraft due to potential lightning-related fuel tank explosion risk.
Why it matters: Operators face mandatory inspections and possible repairs, with estimated inspection costs of $2,890 per affected aircraft; the FAA estimates 60 US-registered aircraft are covered.
