This stopper blocks off the last 4 adjustment holes on the pedal bar.\n\n**Why it matters:**\nWhen flying with one engine failed (single engine operation), pilots need to push hard on the rudder pedals to keep the plane straight. If the pedals were adjusted too far forward (¾ of the way), the force required became dangerously high — exceeding international safety standards set by both European (JAA) and American (FAA) regulators. This created a safety risk where pilots might not be able to control the aircraft adequately during an emergency.\n\n**Who it affects:**\nOwners and operators of specific Dornier 328-100 aircraft with serial numbers 3005–3098, plus individual planes 3101, 3104, 3106, 3107, and 3110.\n\n**What must happen:**\nThe fix must be done within 30 days of 19 January 2006 (so by mid-February 2006), following the manufacturer's service bulletin instructions."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The instrument itself sets a focused scope: a single installation requirement confined to the listed serial numbers with a 30-day compliance window.
