The JT8D engine has proven itself to be a highly durable and reliable engine, having completed more than 673 million dependable flying hours since entering service. Once deemed the workhorse of the industry, more than 14,750 JT8D engines have flown. Today, there are 2,400 engines still in use.
The eight models that make up the JT8D family cover a thrust range from 14,000 to 17,000 pounds. The JT8D-200 series, which entered service in 1980, offers 18,500 to 21,700 pounds of thrust, and is the exclusive power for the popular MD-80 series aircraft. The JT8D-200 builds on the family's excellent reliability and low maintenance costs while meeting noise and emissions regulations.
Pratt & Whitney has developed a new low-emissions combustion system, or E-Kit, that is FAR 25-certified to ensure the JT8D-200 engine stays current with environmental regulations. The E-Kit reduces JT8D-200 engine NOx emissions by 25 percent and exceeds all ICAO standards for new production engines.
