Avro CF-100

Would one of our Canadian expert help me?

In Belgium our air force flew CF-100 MkV with square wing tip and normally tip tanks. We were told, then, that the Mk V had wing extension whereas the Mk IV had original wings.

As unfortunately all surviving BAF Mk.Vs were locally scrapped, a Canadian aircraft, still in RCAF markings, was acquired by the Brussels Air Museum. She is listed as a Mk.V but doesn't feature the extended wingtip.

Thks in advance

I believe that all Mk. Vs were built with the extended wingtips. However, all of the ECM birds did not have them later in service. In fact most of the remaining CAF CF-100s in the 70s and 80s, both the ECM birds or the few misc birds, did not have them. So it is very likely that the Belgium plane was built with the tips and they were later removed when used by the CAF.

I agree with Jim, the ECM Mk5C had the wingtip extensions removed. Some Mk 4's were upgraded to the Mark 5 standard but I think this upgrade included the extension.

Another possibility is that your Clunk has the wings off another CF-100.

Which CF-100 do you have?

#18534

I posted this one on an email list as well. Here is a description of the bolt on wing extensions...

Quote:

The 44-inch, constant-chord extensions were a bolt-on item. They were
added to 49 Mk 4Bs that were converted to Mk 5s and were standard on all
new-build Mk 5s. They were removed from the Mk 5 fighters that were
converted to Mk 5C and 5D EW support trainers.

Note that the Mk 5 also had a tailplane with a 24-inch larger span, no
gun pack, no leading-edge de-icing boots, no RATO bottle fittings, and
no gunsight. The Mks 5C and 5D retained the larger tailplane after the
wingtip extensions were removed.

18534, the CF-100 sold to Belgium (for $1.00), is a Mk 5.

HTH.

I don't think 18534 was ever converted to a MK5C/D, it was used as an instructional airframe. Sorry, I don't have any info on why this airframe is missing the extensions. If it was a training aid it's possible they were removed and never re-installed, they could have been held back as spares for the remaining CF-100 fleet or could have been removed for R&D or other operational reasons. Unless someone has specific info on this Clunk, try contacting the Canada Aviation Museum to see if they have any records on this aircraft.

BTW, on the subject of CF-100's, does anyone have a photo of a CF-100 throttle quadrant installed in the aircraft?

The wing tip extensions are easliy removed and put on. I belive they have to be removed if the tip tanks were to be fitted. I have never seen a photo of the Mk.V with tip tanks and extended wing tanks.

Brian - If you can wait a few weeks I will try to get some photos of the throttle quadrant of the CF-100 on display at the Atlantic Canada Aviation Museum. I can't get there this weekend but should be able to do it the following weekend.

ACAM's CF-100 (s/n 18747) does have the wing tip extensions currently fitted however we have removed them in the past when we need the extra space or moving the aircraft around the hangar.

I think Ken is correct about the tanks. Besides the EWU birds, P&W and ASU had Mk. 5 Clunks that didn't have the extensions...but they did carry tanks. I wonder if they were removed at some point from all CAF Clunks no matter if they were in service or not.

Jim et al--

Of the tip stores that went onto CF-100s, by the mid-sixties when the only Clunks operational were the ECM version, only the tiptanks were still used. (The other two stores carried were different forms of rocket pod...certainly superfluous on an ECM "spoofing" machine!) And yes, the tiptanks mounted only to the standard Mk.4-length wings without extensions. As a result, there are actually rather few Clunks extant that feature the tip extensions. The one in Lee Park in North Bay (a missile-test Mk.5M) has the extensions plus a set of rocket pods; iirc the Mk.5 at Reynolds in Alberta also has extensions.

A curious historical footnote about the Belgian Clunks: the 53 Mk.5s allotted to Belgium were RCAF-contract machines; one of them suffered a gear collapse while still in Canada and was replaced in the Belgian batch by another off the line. The damaged Clunk, 18731, was subsequently repaired and entered RCAF service...and, though the 53 aircraft sent to Belgium were indeed all scrapped in the 60s, 18731 survives to this day as a display airframe at the Royal Military College in Kingston, ON. Maybe the museum in Brussels should arrange with RMC to swap 18534 for 18731, bringing home Belgium's "rightful" last CF-100!

I thank all of you for the info supplied

You are most certainly welcome. Feel free to post here and tell us what is going on in Belgium sometime. I would like to hear news about Belgium Warbirds.

Hi Ken,

Thanks much for the offer and not a hurry. I found a CF-100 throttle quadrant amongst some parts I bought and would like the photo to see how it looks installed.

As suggested by Mike, I will post of warbirds and preserved ex-military aircrafts in Belgium.

The following link is my first tentative with Photobucket:

Hope it will work
