Savoia ,just a thought i was under the impression that when stainless came in contact with Al-clad this can cause a reaction and go on to cause corrosion?,There was and still is a craze for changing normal steel screws for stainless steel ones on fixed wing as well as helicopters,You can bye the full screw kits as i have used before , fitting stainless screws can be a real pain ,even though they are rust proof the metal is soft and very difficult to drill out if snapped and at all times the Al-clad inspection panels have to be paint protected at all times when the panels are replaced ,i hope i got that right!
Although most of the training was being done on grass (Middle Wallop), we were going through skids in Northern Ireland where many landings were on hardstandings, so it was a service engineered modification (you can see the welds where the original short shoes are joined together with a centre section) that EC/AH took on and are now available off the shelf.

And not forgetting 'that video' of four German Police Gazelles flying beneath a bridge!
Skid Shoes
Originally posted by GazEngineer
It's rare we replace skid shoes, as most of the Gazelles land on grass or other soft surfaces, so the wear on them is greatly reduced. Obviously they all land on hard surfaces, but the majority of the time it's to be able to ground handle them for maintenance or storage.
Civilian Gazelles that wear front and rear shoes that land on hard surfaces suffer with eventual damage resulting in the non protected part of the skid tubes being damaged and needed replacement, which is where the military Gazelles full-length shoe helps to increase the life of the skid tube.
With the exception of one Gazelle I know of, the only time you will see full length skid shoes is on military and ex-military Gazelles, due to the stupid rule that despite being the same helicopter using the exact same parts, you can't use military parts on a civilian machine, despite the fact that there is no difference between 98% of the components - hence why people are coming off G reg and going onto Yugo reg and making use of brand new military parts.
Ah yes, grazie Zis, I recall this matter cropped-up before on page 35.
I think I-PTEC must have had some components from 1695 as she keeps coming up on various databases as having a link with this serial no. Hopefully this will get sorted out.
Also on page 35 is a photo of the Nordrhein-Westfalen SA342 D-HAIR, not with a camera mount, but with a speaker mounting which seems to stretch between the skids.

Originally registered in Canada as C-GVWC, then became F-WXFX, F-GGTJ, G-TOPZ and now flies as YU-HPZ.
I think you'll find that ex-G-MANN (cn 1295) is in fact YU-HVZ (belonging to a member of Benegaz) and now living in the Netherlands, whereas ex-G-TOPZ (cn 1473) remains in the UK flying as YU-HPZ. But, with only one letter to distinguish them and given that they are both stretched Gazelles, its an easy distinction to miss!

The time has come to 'wheel out' the 'snow Gazelles' in celebration of this special season. For now (and because my collection of snow Gazelles is somewhat limited) these will be repeats but .. in my next post I shall display some 'new' finds.

We saw E7-SHA in the recent collection of snow Gazelles, and here is another shot of her from 2010:

Nice one Zis! Seeing as you mentioned Ikar, I noticed the other day while adding details to our list of Gazelle service centres that their website no longer seems to be functioning.
One of Aviafora's readers is a friend of mine who used to work as a Technical Support Officer with Aérospatiale. He was very helpful to me when I began researching about Gazelles and provided me with much useful information. He has recently written to me saying how much he enjoys reading Shrieking Gazelles.
Specifically, in confirmation of the recent comments made by GazEngineer my friend says:
The RAF experienced two fatal accidents attributed to a loss of fenestron effectiveness. A third case (fortunately without damage) resulted in the RAF pilot involved in the incident being invited to Marignane to participate (with his aircraft) in test flights specifically relating to the effectiveness of the Gazelle's fenestron.
This RAF pilot flew with one of our test pilots who demonstrated the effectiveness of the fenestron in all flight configurations. This included recovering yaw control from a condition of high speed yaw rotations. One of the test pilot's comments was that the RAF pilot's application of pedal input to arrest the divergent yaw was too gentle, whereas the test pilot recommended that pedal inputs be 'lively' even up to the maximum extent of available pedal if required.
These experiments resulted in an addendum to the UK military Gazelle flight manuals after which it was said there were no further yaw control problems.
Aérospatiale's Gazelle test pilot department stated that throughout the Gazelle's flight envelope, the fenestron would not stall!
Did you know that the fan fitted to the Hughes/U.S. Army/DARPA OH-6A NOTAR prototype was the Fenestron blade disc from a Gazelle?
Apparently so.
Hughes obtained a blade disc and hub assembly for the initial test work. They shortened the blades a little and fitted it to the prototype. The initial prototype was under-powered and loaded with test equipment but flew well enough to prove the concept.
In 1985 Hughes/McDonnell Douglas designed a more efficient blade that was better suited to operating inside the NOTAR tailboom and eventually the NOTAR went into production.
The NOTAR still has a muted Fenestron-whine today.
