I aplogize in advance if this topis has already been discussed, but I did a search for it and didn't really find anything pertaining to what I had in mind.


My questions is: Are there anymore plans to convert and 727's with the baby 8's into "Super 27's" with the -217's? Or is this modification just too exspensive to exspensive to justify at this point? The Super 27 is a nice bird with plenty of power to spare. With all these cargo operators in South America and else where I think it would help give them more lifting capacity. Your thoughts...

I suppose it depends on how much usable life is still in the airframe to determine whether purchasing and installing JT8D-217s is worth the expense.

I think the days of using the 727 as a freighter are over. Even bottom tier cargo carriers are going to the 757. Even the -217's which do offer better fuel burn are still old tech. The engine still has can-annular combustors. It doesn't pay to convert the 727.

Most of the 757F's and SF's are with FedEx, UPS, TNT, DHL and it's contracted carriers such as Blue Dart and Captial Cargo. Not exactly bottom tier. Variglog tried the 757F but went bust (although let's not blame all of that on the aircraft). It will be interesting to see how Arrow Air holds up with them. I know Amerijet has been looking at the 757F for years but just can't make it work so they keep flying the 727's.

The Super27F is still a great cargo airplane. It can meet stage III noise, parts are cheap, and they carry a lot of payload for the space available, about 30T of freight over 12 pallets. Compare that to less than 35T over 15 positions on the 757 conversions and the Super27 had more lifting ability per position.

Granted, the prospects new conversions of a standard 727 to the Super27 are slim in today's world. However, if you can find a pax version Super27 for under $2M, throw in a D check for under $1M and a cargo mod for about $1M and you are ready to roll for under $4M. Compare that to about $8M to buy a low spec 757, add $1.5M for the S4C and another $4.5M for the cargo conversion and you are up to $14M, big bucks for the small guys.

No question it's a great Aircraft. Doesn't the engine modification require ballast up front to balance out their greater weight on the pax Aircraft ?


I believe on the freighters they were able to move #1 and 3 engines forward to compensate as they had no concerns over blocking the rear exits.

I worked for a repair station that did Super 27 mods. We have to bolt 10K of ballast to the forward bulkhead for a Passenger aircraft. As for moving the engines, they are still in the same location, The pylon and engine mounts are changed due to the fact the -200 series engine is bigger around then the older JT8's.

Ten thousand pounds of Ballast ! thats amazing but I can see they had no choice on the pax Aircraft. I had understood that on the freighter conversions they were able to avoid doing this by actually moving the #1 and 3 Engines forward thus blocking both rear exits.


Of course this was not a problem for the freighters. Have you heard of this mod ?

The FedEx Valsan Mod aircraft had ballast in the nose and the 1&3 engines were not moved forward.
I don't think their is much demand for a re-engine 72 these days. FedEx operates 4 Valsan/Super 27 now, and returned 7 to the lease company in late 08 and some ended up being leased by Services air cargo in the Dominican Republic.

I don't know if your agreeing with me or agreeing with me. The first sentence says "most". I won't argue with that. Your last sentence mentions Arrow Air which is certainly botom of the barrel.

Any plane which burns 10000 lbs or more per hour in cruise when gas is $4 per gallon is not going to be good at anything, Flying overnight packages volume is more important than weight capacity.

I don't think the bottom tier cargo carriers can afford the 757F. They can't handle the lease rate or the maintenance costs, especially putting the engines through the shop. Arrow Air will be a test.

The integrators can and will use the 757F. They have better revenue generating ability and overall stronger economics which can bankroll the more expensive aircraft (as compared to the Super27 in this case).

I agree that the fuel burn savings sounds compelling. However, it is only one piece of the equation and it cannot overcome the capital requirements for the "bottom tier" carrier.

The engines are in the same place on a freighter as a passenger airplane, If you moved the engines you would be moving the bulkhead that the pylon is mounted to, and since the aft mount is part of the aft pressure bulkhead I don't see anyone redesigning the aft end of the airplane to move the engines forward a couple of inches when they can add more ballast to the front of the aircraft to offset the weight of the 200 series engines.

Don't forget about Challenge Air Cargo They were operating the 757F back in 1996 and did well with it.

I don't forsee any obstacles with the 757 replacing the 727 in service. Just the same way the A300 replaced the DC8.

Getting rid of the 3rd crew member, much lower fuel burns, and less down time for maintenance all help the bottom line.

Don't forget the 757 has LNAV/VNAV even further decreasing fuel burn.

Fuel burn issues aside, how much of a hot-rod is the 727-100 (or even -200) with JT-8D's and winglets? Get technical here....what kind of field performance and climb performance does it have compared to a 757 at a similar % loading? (Not total weight, but MTOW for the given aircraft, or max load range...etc)

The 2 pax supers I worked on did not have the aft doors blocked. In fact it was rather nice just open the aft doors and look in the inlets. Of course the cargo bird had the aft doors blocked off.

It has been about 2 years but I know/knew of 3 supers sitting in storage. 2 pax and 1 cargo. Talking to the pilots that flew tha cargo super 27, they called it a rocket. Loaded with cargo, just throw the throttles forward and point the nose to the sky.

One of pax the birds just came out of a C check and has been sitting since. Kind of a waste if you ask me.

I just spent 2 hours looking for some performance info on the Super 27. The only thing I found was this forum topic:

Why On 727 Re Engine With JT8 219 (by 747400sp Dec 12 2006 in Tech Ops)

Maybe someone has access to view the Type Certificate for the MOD. Or maybe a pilot who has flown some can shed some light for us.

Here is the STC info:

A little history: This mod was originally designed by Valsan/Rohr in the late 80's. Goodrich acquired Rohr in the mid 90's and relaunched the mod as the Goodrich Super 27.



35 years of American Trans Air/ATA Airlines, 1973-2008. A great little airline that will not be soon forgotten.

At the time the comparisons were made, they were only considering the modified 727 with a baseline model. Since twin engine aircraft are now mainstream for transoceanic flights, much of the advantage of an updated three engine airliner is lost. In addition, at the time of the original STC, the cost of acquiring B757 was much higher than that of 727s. For operators with 727 models already in service, the additional advantage lay in crew training. Only minor differences training was necessary to convert to Super 727.

Today, there is a clear advantage using advanced 737 models or 757. High efficiency high bypass engines, state of art navigation and instrumentation, two pilot cockpits etc. Used twins are on the market while 727 fleets are being retired. Even with Stage III mods, they are noisy, have limited range compared with other available aircraft, require large crew and out of production spares.

Thanks for the info!

There are some pretty interesting number given on the Goodrich presentation. You are more than doubling your payload by upgrading to the -217 engines for a given range. Some of the cost savings can add up pretty quickly.... $100/hr in fuel savings, 20-25k extra in payload. To me it seems that the extra money would add up, the mod would pay for itself in no time.

Quoting ElpinDAB (Reply 12):

MTOW:
757- 255,000 (unsure about the changes due to altitude)
Super 27- 188,000-197,000 (depending on altitude)

Max Load Range:
757- 3150nm
Super 27- Approx 3000nm

Total Volume:
757- 8430 cu ft
727- 6850 cu ft

Back to the issue at hand... If I am soley a 727 freight operator, I believe the benifits of the mod are worth looking into. Heck I would even lease a super 27 for a year to be able to compare numbers side to side the good and the bad. In the end it's all a number game. If i can haul more with what I already own, that automatically translates into more profit.

After Lockheed announced they were shutting down production of the L-1011, they teamed with Pratt and Whitney to re-engine 727's with two (2) PW 2037's. Lockheed even acquired the aft fuselage from an Eastern 727 and set it up in the parking lot of Building 85 in Burbank. While some engineering work was accomplished, Lockheed could not find an airline partner to share the cost and the program (along with the aft fuselage) was scraped.

That is true, I agree with you. However there are still some questions about how many 757's are actually out there available for purchase or lease. Also if I am a compay the size of Amerijet or smaller, and I am competeing against Fed-Ex or UPS, for this aircraft, the chances of me getting it are slim. I'm not trying to dog the smaller companies, but if you are a company looking to lease or sell this 757, and UPS or FED-Ex is willing, and more importantly, can pay more, who are you going to sell it to? Simple supply in demand. So if I am this smaller company and can wait a few more years when there are more 757's to buy, why not upgrade your current aircraft to help keep your company competitive, and heck even make a few extra dollars to be able to start buying the replacement aircraft.

With acquisition costs considered as a primary factor, how long would it take before a Super 727-100 would become more expensive than a BBJ (737-700 base)?

More to that point, what bank or leasing company is going to take the risk of lending/leasing to a small shoe-string budget cargo carrier when the asset has gone from a $2M 727F up to a $12-15M 757F? Amerijet can't afford to install or maintain toilets, how are they going to handle the increase in lease rate from $50k/mo for a 727F up to $200k/mo for a 757F? If they could, they would have them by now.

As far as a hauling freight on the super-27, it's not a big advantage. Realistically you aren't going to be hauling more freight because in most cases we are dealing with short runways(advantage to the 757). After looking at the numbers as a small freight operator would, all that would probably end up happening is some fuel savings of maybe a couple thousand pounds per leg. That may sound all good, but now you have to get all the support to have -217 motors in your fleet so now you have an oddball engine.

Being new to a 3 man cockpit, I am loving having the FE back there. It is going to be a really sad day for me as well as many others when that is a thing of the past. I'm glad I am at least getting in on the tail end of the good old days!
