Operators of all models of the Cessna CitationJet/CJ1/M2 and CJ2 series light jets can now install SkyWay Group’s SkyFlush externally serviced lavatory modification. SkyWay recently expanded the applicability of the SkyFlush supplemental type certificate (STC) to accommodate the CitationJet/CJ1/M2 series.

The modification adds a ground-service-compatible external service panel behind the wing on the left side of the fuselage, according to SkyWay. “This panel, mounted aft of the wing on the left side of the fuselage, includes an aviation-standard four-inch waste drain fitting, blue-water service fitting, LED system-status indicator, and switches for operating the integrated macerator pump and filling the system with water and deodorizer.”
