Summary

We propose to adopt a new airworthiness directive (AD) for certain Saab AB, Saab Aeronautics Model SAAB 2000 airplanes. This proposed AD was prompted by an occurrence that was reported of rudder pedal restriction on a SAAB Model 2000 airplane with the large potable water system (LPWS) installed, equipped with in-line heaters. This proposed AD would require installation of shrinkable tubes on the water piping of the basic potable water system (BPWS). We are proposing this AD to prevent water spray in case of a failed pipe or coupling during water filling on the ground. This condition, if not corrected, could freeze parts of the flight control system possibly resulting in reduced control of the airplane.

The agency’s own summary, as published.
