That is a very highly stressed engine. Having that much trouble so soon really does point to something being done wrong at the overhaul. I have never worked on an engine with Simmons injection, but I understand that there is little that can be done in the field to affect fuel flow. It has to be properly setup on the bench. That is where good and complete modern engine instrumentation can save the day. If fuel flows, EGTs and CHTs are not where they should be, we pilots can abort the mission and, possibly, save the engine that has been improperly rigged. Unfortunately, neither the instrumentation nor the Simmons Injection is cheap!

The engine was overhauled in 2000 with only 146.3 hours. ________________________________ Message 2 _____________________________________ Time: 06:29:35 AM PST US From: BobsV35B@aol.com Subject: Re: Commander-List: EBay 680FL N4998E-SN1739-141 In a message dated 6/17/2006 1:08:30 A.M.

We pilots do have to comply with the limits set by the manufacturer!

He gave me permission to share this. Here goes! (Thanks John!) Bob & Tylor, I read your comments on the TCFG web page. For some reason with my computer I cannot respond to the web page. I thought I would give you a little information about the 680FL's we had. In 1986 we purchased 2 680FL's and sold them in 1989, they were used for UPS cargo and at the time we had 20 500B's. We changed more cylinders in the 680FL's than all of the 500B's combined. It was a fun aircraft to fly but the engines were just a nightmare for us in our operation. The last straw was one morning coming out of ICT deadheading home 1,500 lbs under gross we lost an engine right after takeoff after raising the landing gear and our very experienced 680FL pilot was only able to get the aircraft to about 300 agl and returned to ICT and landed safely. I called UPS and said we just cannot fly the 680FL's for you anymore, we can provide 2 500B's at the same price but we cannot fly the 680FL's anymore. UPS is a very hard company to fly for but the management knew I was serious and they took our 2 plane offer. I could go on about all of the things we looked into to try to get the aircraft to work (changing to 8 cylinder engines etc) but it still was not going to solve the single engine performance problems that existed. I think if a 680FL owner could only be the one that flies his/her aircraft a person would have the best chance with the 680FL engines and aircraft. PS-If you want to share the above info with the TCFG group feel free.
