FAA proposes airworthiness directive for Bombardier BD-700 fuel leak risk

The FAA proposes a new airworthiness directive for certain Bombardier BD-700-2A12 aircraft after fuel leakage near rib 6 was found during production pressure testing, caused by oversized fastener holes. The directive would mandate inspections and corrective actions. This is a routine regulatory safety action, not a market-moving event.
