FAA Proposes Improved Rudder System On Boeing 737s

The Federal Aviation Administration (FAA) today published a proposal to mandate installation of a new, improved rudder control system in all Boeing 737 models within five years.

Today's proposed airworthiness directive (AD) would require Boeing 737 operators to install a new rudder system, which is currently being developed by Boeing, and make any additional changes to the aircraft needed to accommodate the new system, within five years of the AD effective date.

The order would affect about 2,000 US-registered airplanes at an estimated total cost of approximately USD$364 million. There are about 4,500 737s in the worldwide fleet. Comments on the proposed AD are due within 60 days.
