The U.S. Federal Aviation Administration (FAA) on Monday ordered inspections of Boeing 767 airplanes, saying problems with the elevator system that helps the jet climb and descend could result in a "possible loss of control of the airplane."
The FAA said in an online notice that the safety checks were " prompted by reports of failed shear rivets in the bellcrank assemblies of the elevator power control actuator." The parts in question have not been linked to any accidents involving the popular jet.
The agency said it has issued the airworthiness directive to " prevent continued operation with yielded or failed shear rivets" and "to prevent certain failures or jams in the elevator system from causing a hardover of the elevator surface, resulting in a significant pitch upset and possible loss of control of the airplane."
The order, which takes effect on March 3, applies to all the Boeing 767-200, -300, -300F, and -400ER series airplanes. The FAA estimated that it would affect 415 U.S.-registered airplanes.
