The Cessna 550 Models
Essex Boy:
I flew the Cessna 550 between 1981 and 1996 and cannot say that I had the
popping sounds as described.
What I can say is that I had three (3) cases of total loss of pressurization all from 41000 ft. It certainly got my attention, the engineers attention and the attention of the Cessna Company. The model had the pressurization system. modified as a result of the investigation.
