Westwind c/n 154 started its life as an 1123 model in 1972, but was kept by IAI as a development aircraft and had been converted into the 1124 prototype by 1976. - As D-CBBE, it stayed on the German register between 1986 and 1996, flying with RFB on military contracts. - The aircraft was last registered as N176DT and observed flying to Goodyear AZ in March 2015, probably to be retired.

Modified from a standard Westwind as the Westwind Sea Scan, an unsuccessful contender for the US Coastguard maritime patrol aircraft. Later returned to standard configuration and became N919JH, then D-CBBE, N722AW, N176AK, and finally N176DT, cancelled on 9 August 2018.
