12/31/2007. Remarks by Johan Visschedijk: "Originally built as a BO 105C D-HDCI was registered in December 1972, the following year it was rebuilt as the BO 106 V1 prototype. Fitted with a wider cabin seating seven persons, the aircraft BO 106 was first flown on September 25, 1973. It was not taken into series production.

In this view the BO 106 is seen accompanied by the BO 105C D-HDBY. Built also in 1973, D-HDBY was sold to Japan in 1975, registered as JA9523, while in 1993 it was registered in the USA as N174MC. It is still at the FAA Register as of this day."
