    Hey old Bob!......Once again our past lives seem to share a common thread. I also got my multi in a Bobcat based at MDW when it was listed as the world's busiest airport. I think Cessna dubbed it the Bobcat to give it a more macho sounding name for the military model which was the T-50 I think. You left out the often used nickname for the civilian model: Useless 78 (UC-78). If anyone remembers the old TV series Sky King the original Skybird was a Bobcat. I enjoyed my time in ours & with a light load & resonable altitude I was amazed at how much time you had with one back at idle to pick out the site of your impact. Later, in the midst of a hot & humid midwest summer, I found myself giving multi instruction in an early Piper Apache for a school who's policy was to put 3 students & an instructor in the aircraft on the theory that the back seaters would absorb some of the training procedures before taking their turns in the left front seat. One time when we landed to play musical chairs, one of my back seaters jumped to the ground & vowed that however long he lived he would never again allow his feet to be separated from mother earth........for a minute or two I seriously considered joining him. Fortunately our friendly FAA inspector convinced the boss that this training procedure was not in the best interests of aviation safety. Also I believe we were consuming more barfbags per hour than fuel. I do believe that the old Bobcat with its "Shaky-Jakes" could have pulled it off much better than the Apache with its "Little Lycs".

    Subject: Prop governor cable
    Good Morning Dan, I received my multi-engine training in 1950 while working for Tufts Edgecombe at Elmhurst Airport which was just northwest of the Outer Marker for Rwy 13 Right at Midway. One of his bombers had the 300 Lycomings installed. It would actually maintain altitude with one engine throttled back to idle as long as we were way below gross. Spent the summer flying charters with the Cessnas to Northern Wisconsin resorts. A couple years after I started with UAL in 1951, my old boss got a set of Hartzell full feathering props approved on his Lycoming powered Bobcat. It would easily out perform the Apache when it came on the scene. We must have crossed paths somewhere between Midway and Elmhurst as I have continued to fly in the area ever since. Who's Apache were you flying? Hope you are enjoying the desert!

    No it was a 680T with the TPE331-43's and was later converted to a 680V. Not exactly sure what was changed besides the engines and props, perhaps Barry could tell us. It was always a Turbo Commander, just a very early model. Only the 22nd made. Bert **************It's Tax Time! Get tips, forms and advice on AOL Money & Finance.

    Hi All, The 680V was not really that much different to the 680T. Major items were: Increased MTOW from 8,950 lb. to 9,400 lb. Some had the "Miller" nose incorporated. Some had the "Picture" or "Panoramic" windows incorporated. Besides those built by the factory as a 680V (26 in all), numerous others were converted from a 680T (possibly 51).

    Anyone know WHAT this is? Is it a conversion or factory turbines... (pre Century) What does that mean? The small engines? The AC680T was the first production model Turbo Commander.? All of the 680 Turbine series had the Garrett dash 43 engines, ranging from 43, 43A and 43BL.?? The Century series were any dash number at or above 100, such as TPE 331-151K.? Saying this is a 680T with a -43A conversion means they put the later engine on the earlier airframe. The -43 series did not offer much more power than the piston engine on the AC680FL and were very temperature critical, meaning as soon as it was over 15C, you were losing power.? Each upgrade dash number was slight improvement. An "interesting" aspect of this airplane is the "engines 200 SMOH by Garrett/1538 SMOH by AiResearch."? I don't think Garrett/AiResearch has supported this engine in a long long time.? Last facility I knew that supported this engine was Bob Hancock of Hancock Turbines outside of Nashville, TN., but then the airplane has not flown much at all, so the engine SMOH statement is probably right. The AC680T used a hydraulic (Skydrol) powered cabin supercharger.? The AC680V and up used bleed air.? The AC680W was the first all Weather model (certified known ice) and a Century Conversion that would place a flat-rated 525shp all the way to altitude is a screamer. The Achilles Heel of this model is actually the New York Airbrake 3000 psi hydraulic pump used to drive the cabin supercharger.? The utility system is stepped down to the normal Commander hydraulic system pressures.? This pump is damn near impossible to find.? The two 680Ts I was involved with burned up these pumps within a few hours -- turned out they were lower output pumps field modified to make 3000 psi, or so thought the fellow supplying us with them.? Not so. If you remove the pressurization system, a lower output pump could be used.??? If used as an upressurized camera ship, this could be OK ... if being equipped with an orphaned engine is OK.? To be fair, if you're not too far from Hancock's place, you'd have excellent support. This all off the top of my head ... or the more aptly, the bottom where all the facts are mixed in with all kinds of sediment.? I trust Sir Barry to come up with the proper dash numbers, engine powers, etc. Wing Commander Gordon Life is not simple anywhere. Probably less so elsewhere.

    Subject: Re: Commander on E-bay
    Hello All, When it first came on the market, the 680T had TPE331-29A engines and a wing span of 49ft. 0.56 inches. The factory called all of these back and they were re-engined with TPE331-43 engines and had the wing span reduced to 44ft. 9.7 inches. They also had their original 84-inch diameter props replaced with 90-inch ones. As the Wing Commander points out, some Commanders that had the pre TPE331-5 series engines had them replaced with TPE-331-1-151K and were known as "Century Turbos". Regarding the TPE331-43BL, these were a factory standard installation introduced on the 680W "Turbo II" Commander, but the first Commander to utilise that engine with bleed air for the pressurization and environmental systems was the Model 681 "Hawk".

This all off the top of my head ... or the more aptly, the bottom where all the facts are mixed in with all kinds of sediment. I trust Sir Barry to come up with the proper dash numbers, engine powers, etc. Wing Commander Gordon Life is not simple anywhere. Probably less so elsewhere. ------------------------------------------------------------------------- ----- Get the MapQuest Toolbar, Maps, Traffic, Directions & More!

Gordon To: commander-list@matronics.com Sent: Wednesday, April 16, 2008 12:31 PM Subject: Re: Commander-List: Commander on E-bay Anyone know WHAT this is? Is it a conversion or factory turbines... (pre Century) What does that mean? The small engines? The AC680T was the first production model Turbo Commander. All of the 680 Turbine series had the Garrett dash 43 engines, ranging from 43, 43A and 43BL. The Century series were any dash number at or above 100, such as TPE 331-151K. Saying this is a 680T with a -43A conversion means they put the later engine on the earlier airframe. The -43 series did not offer much more power than the piston engine on the AC680FL and were very temperature critical, meaning as soon as it was over 15C, you were losing power. Each upgrade dash number was slight improvement. An "interesting" aspect of this airplane is the "engines 200 SMOH by Garrett/1538 SMOH by AiResearch." I don't think Garrett/AiResearch has supported this engine in a long long time. Last facility I knew that supported this engine was Bob Hancock of Hancock Turbines outside of Nashville, TN., but then the airplane has not flown much at all, so the engine SMOH statement is probably right. The AC680T used a hydraulic (Skydrol) powered cabin supercharger. The AC680V and up used bleed air. The AC680W was the first all Weather model (certified known ice) and a Century Conversion that would place a flat-rated 525shp all the way to altitude is a scr eamer. The Achilles Heel of this model is actually the New York Airbrake 3000 psi hydraulic pump used to drive the cabin supercharger. The utility system is stepped down to the normal Commander hydraulic system pressures. This pump is damn near impossible to find. The two 680Ts I was involved with burned up these pumps within a few hours -- turned out they were lower output pumps field modified to make 3000 psi, or so thought the fellow supplying us with them. Not so. If you remove the pressurization system, a lower output pump could be used. If used as an upressurized camera ship, this could be OK ... if being equipped with an orphaned engine is OK. To be fair, if you're not too far from Hancock's place, you'd have excellent support.

    Chris! You just couldn't stay away from Commanders, could you?? Nice to see your post.?? I'm lurking around here still, answering questions and offering useless advice when I can.? Am very busy, flying the Falcon 20 full time and living the lesson (again) about volunteering.?? Got hip deep in the Las Vegas airspace redesign, representing Biz Av on RNAV SIDs and STARs development, am the lead on building an RNAV SID at Henderson (KHND) and got drafted into a national work group for Pilot/Controller Procedures & Phraseology. With all that, I get about 180 emails a day and do my best to keep my eye on the Twin Commander net.?? There's still a few of us left and lots of new talent has risen to fill the gaps left by those who have moved on to other, lesser, aviation products.? ;-) Best, Wing Commander Gordon Life is not simple anywhere.

    G'Day Russell!? Nice to know you're still around, even if you are upside down.? Shaminda says TCAC can't supply him with a Structures Repair Manual, which is beyond my understanding, so I hope someone in this hemisphere can help the fleet out Down Under.
