Airbus helicopters must get their main rotor bolts checked for loosening
What happened
The US aviation regulator is requiring inspections for several models of Airbus helicopters. This is because reports show that the main rotor servo-control bolts can lose their tightening torque, which could lead to unsafe conditions.
Why it matters
Helicopter parts are under constant stress. Even small components can fail, leading to serious accidents. This directive forces operators to check a specific part that has shown a tendency to loosen, preventing potential failures before they happen.
The signal
Watch for any further reports of loosening bolts on these helicopter models after the inspections are completed, which would indicate the fix was insufficient.
