Airbus helicopter engine throttles get a permanent fix for a known idle problem

The US aviation regulator is updating rules for certain Airbus helicopters to fix a problem where the engine stays in idle mode. This new rule adds a permanent modification that stops the need for repeated inspections of the throttle twist grip.

Helicopter operators previously had to perform regular inspections to catch a known throttle issue. This new rule means they can install a permanent fix instead. This reduces ongoing maintenance costs and removes a recurring safety risk for these specific helicopter models.
