Dan Air Hump-backed Boeing 727

Fri Sep 22, 2006 3:09 am

I think my medication may be wearing off....

But was there ever a boeing 727 operated by Dan Air that had some sort of reinforced "hump" on its back....?

I seem to remember visting MAN in the eighties and hearing people talk about it. They used to say that it had been involved in an incident in the US somewhere, and Dan Air had bought the aircraft at a low price and patched it up.

Does anyone know any more about this particular aircraft? I have had a sniff round the net - but can't seem to find anything... now i am beginning to wonder whether I am having some sort of breakdown !!

Regards, BEWLEY747

For some reason that rings a bell with me, but I cannot recall particulars.

Hi Bewley747

No you're not going mad! The 727 in question is G-BMLP which had an accident whilst it was owned by Mexicana. The hump is clearly visible in this pic:

The "hump" is an ADF antenna which is located aft of the main wheel wells on other 727 aircraft. The ex-Mexicana 727's had JATO bottles installed in that area.
This plane is built to withstand anything... except a bad pilot.

Bit big for an ADF antenna? The ones I used to fit to Helicopters were way, way smaller than that - why so large in this case?

I have never heard of JATO being fitted to any 727 but I stand to be corrected - anybody got any pics of them fitted?

If it was a repair seems a bit over the top, but it must have been an approved repair if it was. But why is the repair external to the fuselage? Anybody know what the alleged accident was?

The hardest landing I have ever had was in a Dan Dare 727 at Gatwick - we hit the ground so hard that many of the oxygen masks fell out of the ceiling!

If you use the search engine on this site and look for "Boeing 727-264" (i.e. the Mexicana variant) you'll find several of them that have this fuselage "bump". It is nothing to do with an accident repair!

I remember BMLP very well. It was nicknamed "Lumpy Papa"!

It then went on to serve several operators around the world, including Transmile of Malaysia and I have it recorded as stored at Roswell

Irish251 - thanks for that pic - something else I have learnt. Do you know if the roof hump is indeed a ADF antenna? As I said previously its seems enormously over-size just for an ADF antenna.

Thanks

Anyone care to share what JATO is? I think it might be a little extra booster to help on takeoff. If that's what it is, I never knew those saw time on actual commercial aircraft. Any one have any pictures of one in operation?

Jet Assisted Take Off. There are four solid propellant rocket engines that provide extra thrust should the condition require it.

ONA's DC-9 fleet also had JATO.

AHH! Ferret - thanks for that. The humps are Air con pipes re-routed due to the JATO installation - apparently nothing to do with an accident or ADF antenna then - both seemingly innocently placed red Herrings in the search for the real answer : -) . Thanks for the help and clarification.

He posted a photo from another site which doesn't allow that. Instead of the image, you get the header of that website in the same size as the picture you intended to post. That's why it's blurred, if you click it you'll know what site it's from.  Wink

Interesting, I never knew JATO was ever fitted to civilian aircraft.

What exactly would warrant a JATO takeoff on a commercial aircraft? Short runway? High altitude?

The JATO system installed in on the Mexicana 727's were never actively used during PAX service. They were only to be used if an engine was lost during take off. The few pictures that are floating around were taken during testing or pilot training.

One thing is fer shore - Dan Air had a 727 which Mexicana banged up real bad, it made an unintentional gear up landing on a training mission, and caught fire. The aircraft was considered a write off but was repaired and sold to Dan Air. I have the details of the damage but they're in storage.

On a personal note, I flew on an Iran Aseman ("Iranian Sky" in Farsi) 727 from Dubai to Tehran a few weeks ago, the aircraft was a non-ADV machine from Air France, and it was such a beautiful aircraft. The takeoff roll at DXB went on forever, and even after rotating we just sat on the main gear for a while before gently waddling into the air and steaming out over the bay, not climbing much. (I can see why you'd want JATO after an engine fire at a high airport on a hot day!) The flight was smooth and I loved every second of it. Thanks Boeing and Iran Aseman Airlines.
