As an AI language model, I do not have access to real-time information. However, here is the information about the JT12 engine sourced from the available information on the internet:

The JT12 engine is a turbojet engine developed by Pratt & Whitney Canada. It was first introduced in the 1950s and was originally designed for small business jets and military aircraft. The engine has a thrust output ranging from 1,900 to 2,200 pounds and is known for its high reliability and durability.

Over the years, the engine has been improved and updated with the latest technology to increase its efficiency and performance. Today, it is still used in a wide range of aircraft, including the Learjet 25, the Mitsubishi MU-300 Diamond, and the Lockheed JetStar.

Despite being an older engine design, the JT12 is still considered a reliable and cost-effective choice for many aircraft operators. Its relatively low maintenance requirements make it popular with business jet owners who are looking for an engine with a long service life.
