International Water-Guard (booth 4861) has developed an in-flight drain system as a retrofit package with supplemental type certificate for the Boeing Business Jet.
"An operational concern with 737-derived VIP aircraft has been the inability to drain the aircraft water system in flight", says IWG president and chief executive David Fox. "So to avoid a potentially damaging system freeze in cold weather, crews must stay with the aircraft to make sure it completely drains on the ground.
"Our solution is the installation of a new drain mast with associated water lines and controls that allow draining during the aircraft's descent. We are working now on a cost effective STC kit that will be available by the third quarter of 2010 for installation by any qualified completion or service center", he says.
Several similar one-off installations have been approved in the past, but none as a standard modification available to all operators.
British Colombia, Canada-based IWG also supplies a circulating potable water system for BBJs.
