About

The Yakovlev Yak-42 (Russian: Яковлев Як-42; NATO reporting name: "Clobber") is a 100-120-seat three-engined mid-range passenger jet developed in the mid 1970s to replace the obsolete Tupolev Tu-134. It was the first airliner produced in the Soviet Union to be powered by modern high-bypass turbofan engines.

In 1972, the Yakovlev design bureau started work on a short- to medium-range airliner capable of carrying 100–120 passengers. It was intended to be a replacement for the Tupolev Tu-134 jet as well as the Ilyushin Il-18, Antonov An-24 and An-26 turboprop airliners. While the new airliner was required to operate from relatively small airfields while maintaining good economy, as many Soviet airports had been upgraded to accommodate more advanced aircraft, it did not have to have the same ability to operate from grass strips as Yakovlev's smaller Yak-40. The requirement resulted in the largest, heaviest and most powerful aircraft designed by Yakovlev.

Initial design proposals included a straight-wing airliner powered by two Soloviev D-30 turbofans and resembling an enlarged Yak-40, but this was rejected as it was considered uncompetitive compared to Western airliners powered by high bypass ratio turbofans. Yakovlev settled on a design powered by three of the new Lotarev D-36 three-shaft high-bypass turbofans, which were to provide 63.90 kN (14,330 lbf) of thrust. Unlike the Yak-40, the new airliner would have swept wings.

The first of three prototypes, which was fitted with an 11-degree wing and registered SSSR-1974, made its maiden flight on 7 March 1975. It was followed by the second prototype, (SSSR-1975) with the 23-degree wing and a cabin with 20 rows of windows instead of 17 in the first prototype, and a third prototype (SSSR-1976) fitted with improved de-icing gear.

Lion Air in its early days also uses the Soviet/Russian made Yakovlev Yak-42D to serve some international routes alongside their initial fleet of Boeing 737-200s. The airline even operates five of them (RA-42430, RA-42408 (the one featured here), RA-42412), RA-42387, and RA-42413). RA-42408 which was featured here is the only one that uses proper livery, the rest of them still uses Aeroflot-ish livery and some even still has Russian flag on it instead of Indonesian one. As like the other early fleet of Lion Air, these planes didn't last long. These along with A310 was retired and replaced with McDonnell Douglas MD-83

In the past I created a Lion Air Yak-42 too. But because of my livery making skill back then is still bad so it didn't really same as the original
