In the mid 1990's, the N250 was an ambitious commuter aircraft project of IPTN (Industri Pesawat Terbang Nusantara, now Indonesian Aerospace). The 50-seat prototype N250-50 c/n PA-1 registered PK-XNG first flew on August 10, 1995, followed by the longer 2nd prototype on December 19, 1996. The project was to counter the sucessful ATR-42/72 series aircraft but unfortunately, the asian financial crisis of 1997 killed the N250 project altogether. In this 2009 picture, the 2nd prototype (64-68 seats layout) can be seen sitting abandoned on IPTN's premisis in Bandung, Java.
