The Federal Aviation Administration has ordered inspections of nearly 2,000 Boeing 737 Next Generation (737NG) aircraft after multiple operators reported incidents in which the planes' noses moved up and down during flight. The airworthiness directive (AD) targets excessive movement in the hinges and jackscrew that support and move the aircraft's horizontal stabilizer.
