Graybeard,
the following short note from the NTSB,
CEN10RA135 , says that an aircraft from Eisele Flugdienst GmbH, D-IEFA, suffered an uncontained "event" on March 1.
The citation came from forget (which citation I overlooked) and repeated by infrequentflyer789 on the R&N ash thread, in answer to my query.
I found two paint schemes from Eisele in pictures on the WWW, and one paint scheme fits the pictures I was inquiring about, to which you may also be referring. The registration in those pictures is a D-reg.
March 1 is before the volcanic ash started causing problems.
