Airworthiness Directive · Amendment 39-19143 · Water/waste
The Boeing Company Airplanes
This AD applies to The Boeing Company Model 767-200, -300, and -400ER series airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin 767-38A0073, Revision 3, dated September 8, 2016 (“Boeing Alert Service Bulletin 767-38A0073, R3”).
We are superseding Airworthiness Directive (AD) 2017-02-03, which applied to certain The Boeing Company Model 767-200, -300, and - 400ER series airplanes. AD 2017-02-03 required inspection of the plastic potable water coupling, and corrective actions if necessary; installation of new spray shrouds; and inspection of previously installed spray shields, and related investigative and corrective actions if necessary. This AD adds airplanes to the applicability and, for certain airplanes, requires hose assembly removals and installations. This AD was prompted by a report of a malfunction of the engine indication and crew alerting system (EICAS) during flight. We are issuing this AD to address the unsafe condition on these products.
