Boeing 767 series operators are to examine their fleets for elevator system faults, according to a Federal Aviation Administration airworthiness directive.
The FAA is quick to point out that it has received "no factual information that indicates that this condition is related to an accident involving a Boeing 767 series aircraft that occurred off the coast of Massachusetts".
The cause of that accident - the 31 October 1999 EgyptAir crash killing all 217 people on board - is still under investigation, the FAA points out.
Operators must check the condition of the shear rivets in all six bellcrank assemblies for the elevator power control actuators within 90 days.
An earlier Boeing alert service bulletin had advised repetitive tests of the elevator rigging to ensure that it was rigged correctly, using one hydraulic system at a time and comparing the action of the control surfaces.
