FAA Warns Of 747 Vibration Danger

An FAA service bulletin has said that the latest 747-8 could potentially experience dangerous vibrations in “limited situations”.

The regulator said data analysis showed “divergent flutter”, which could cause aircraft wings to break up, might occur during a scenario that it described as a “high g-load manoeuvre in combination with certain system failures”.

Applicable to eight 747s in the US, the FAA said that the aircraft’s operators are required to make wing modifications in the next one to five years to avoid safety issues, with manufacturer Boeing committing to covering the repair cost of around $400,000 per aircraft.
