Beech UB-056 was wfu by 2013; its final operator was Pineapple Air, and its last registration N157PA was cancelled in 2016.

RWL operated two Beech 1900s (D-CAPA and D-CESA) from its base at Mönchengladbach between 1990 and 1992. Even scheduled flights to Berlin, Erfurt and Dresden were offered for a short time. But it was probably not successful, both aircraft were seen parked at the Beech maintenance facility at Augsburg already in March 1992. D-CAPA was sold to Topair as OK-SEB in November that year.
