In total, 443 BK117s were made; 329 (and two prototypes) by MBB at Donauworth, 111 (and one prototype) by Kawasaki in Japan. Japanese Production: BK117 A-1 to C-1: C/N 1001-1112 = 111 + P-3 Prototype German Production: BK117 A-1 to B-2: C/N 7001-7275 = 274 BK117 C-1: C/N 7500-7555 = 55 + P-2 Prototype + S-01 Pre-production Prototype Although the vast majority have ended up as part of various fleets all painted the same, such as DRF or ADAC, a few of these began life in a factory paint scheme before being sold. In many cases MBB exhibited these factory schemes at various airshows and trade fairs, giving a chance for these now-forgotten paint schemes to be seen before they were quickly repainted in nondescript colours prior to delivery to the customer. Due to the high cost of buying the BK117 - or indeed any helicopter - very few have ended up in private hands, so the chance of finding many individual paint schemes becomes smaller still. Worthy of note is that in the 1980s MBB were quick to use the services of fêted designers and painters to customise selected BK117s to use as promotional items. Walter Maurer repainted c/n 7007 in the highly visual scheme seen within these pages, and Luigi Colani was contracted to customise c/n 7017 in the now-famous "Starship" livery. The latter was created to commemorate the passing of Halley's Comet in 1986. Coincidentally, at that time MBB was advertising the BK117's spacious cabin under the slogan "The BK117 Space Ship" which prompted one distributor to have unofficial "Space Ship" decals made up for the machines they sold. What this means is that while the huge majority of the BK117s are today in plain company colours, a few of them started out with individual and pleasing colour schemes and it is these that I hope to have represented in these pages. For anyone wondering what the variants are: BK117 A-1 Fitted with Lycoming LTS 101-650B-1 turbines. BK117 A-3 Larger tail rotor, Yaw CSAS, SPAS, take-off weight increased to 3,200 kg (7,055 lb). BK117 A-4 Increased transmission limits, improved tail rotor head. BK117 B-1 Fitted with LTS 101-750B-1 turbines, increased performance, and 140 kg (309 lb) increase in payload. BK117 B-2 Fitted with Allied Signal Lycoming LTS101-750B-1 turbines, new tail rotor blades. Max Gross Weight increased to 3,350 kg BK117 C-1 Fitted with Turbomeca Arriel 1E/1E2 turbines. BK117 850D-2 Fitted with Honeywell LTS 101-850B-2 turbines, improving OEI and Cat A performance.
