History: The XJ-137 was intended to be Type IV for the competition, which required a ~100 seat capacity. Unfortunately this capacity requirement wasn't met by the aircraft, but it was planned that a longer version with newer engines and larger vertical stabilisers would be built (which would be designated XJ-137B), but this never happened. NOTE: aircraft is not mine but the livery on it is mine.

About Conviasa From Wikipedia.

Línea Aérea Conviasa (legally Consorcio Venezolano de Industrias Aeronáuticas y Servicios Aéreos) is a Venezuelan airline with its headquarters on the grounds of Simón Bolívar International Airport in Maiquetía, Venezuela, near Caracas. It is the flag carrier and largest airline of Venezuela, operating services to domestic destinations and to destinations in the Caribbean and South America. Conviasa is known to make routes from a political perspective rather than a financial standpoint. In January 1997, Venezuela's former flag carrier, Viasa, ceased operations after 37 years of service due to prolonged financial problems. In May 2001, the idea to create a new flag carrier for Venezuela was proposed, but in December 2002, the project was put on hold until October 1, 2003. On March 31, 2004, then President of Venezuela, Hugo Chávez, signed a decree that formally established the airline. This decree was published in the nation's official gazette the next day.
