I worked on the assembly floor In Middletown, Ct in the late 70s on the -9. -11 -15 ,17 and -17RB. A couple of the customers I remember building JT8s for I flew on 3-4;times a month for about 15 years starting in 1980 commuting to and from work in the Arctic. I remember they had a 208 up in the test building. Myself and my co-worker worked so fast when things got slow the foreman told us to take a walk around and let the slow guys keep busy.

your are right its the -200 series because of the single stage fan.

Jt8d is a low bypass turbofan. Notice the long duct on the inside of the engine.

@@BGTech1 ok bro thank ya :D

@The Boeing Kid Same thing 😹

@The Boeing Kid yeah

Maxwell Harris JT8D was based on the J52. J75, scaled up J57, had the JT4 as its commercial companion.

The J57 turbojet was also used on some 1950s jet airliners, where it was known as the JT3C: its turbofan variant the JT3D was known as TF33 in military use. No civilian aircraft ever used the J52 turbojet (if they had it would have been known as JT8A) while the Volvo RM8 was a military afterburning variant of the JT8D turbofan used in the SAAB Viggen.
