JT8D-200 On 707?

Fri Feb 04, 2005 7:42 am

http://www.flightsafe.co.uk/engines.html

says the JT8D-219 is known to be used on the 707-320C. As I recall it was tried, but I didn't know it went into service on the 707. How many are there, if any? Any pics?

The USAF wants to reengine the E-8 J-STARS with them. They can't use CFM56s, as the nacelles will interfere with the belly radar scan pattern. The project is still alive, but progressing slowly.

Quiet Skies (actually Burbank Aeronautical II) is dead. They went Chapter 11 a few years ago. I personally got stiffed for $19,000 worth of work I had done for them.

JP 2001-2002 says N88ZL and N717QS, pictured above, are both JT3D-powered. So far as anyone knows there has only been one conversion? Is it still flying/flyable with the -219s?

N717QS still had JT3Ds installed, but the nacelles were all new. N88Zl appears to have the BAC II nacelles too, so it would still have JT3Ds. Only N707HE has been reengined with JT8D-200s.

In the late 1970s Boeing offered the B-707-700 with CFM-56 engines. I don't believe they had any sales for the model to military forces. The USN bought it as the E-6A/B Mercury, RAF and French Air Force bought them as E-3F, and the RSAF bought them as E-3s and KE-3s.

The one and only 707-700 was later reengined with JT3Ds and eventually ended up with Israel Air Force. This is it today:

You're right - the only CFM56 powered 707s were those you listed, plus the one off YE-8B (purchased by the US Navy as a E-6B). This was traded to Omega for some used 707-320s, which were turned into E-8Cs. The YE-8B airframe ended up in Saudi Arabia.

I thought the YE-8B is now a USN E-6. Was I thinking of another?

Don't forget the KE-3 tankers of the Saudi Air Force. These are powered by CFM56s and I think there are 8.

Check the 707 production census:

Its now used as a training aircraft in the RSAF. It saves the E-3s and KE-3s from the wear and tear of training. Funny thing is that this aircraft is EMP hardened...
