Winglets

[Jenya]

These look really good Jenya!

Two questions:

1. Were they developed locally? (by you, I am assuming so)

2. Besides an increase in airspeed, what can one expect in terms of any changes to flying characteristics of your wing/aircraft with the winglets fitted?

Many thanks,

John

Hi John
1. These winglets have been designed by Aeros LTD in Kiev Ukraine (big company - manufacturer of hang glider, microlights, Skyranger fix wing plane, para gliders, kites and many other things for sport aviation.
For few years I imported those winglets, and installed them on my topless wings Stratos TL, which we manufacture in SA.
We also installed those winglets on Stranger wings which have converted to the topless.
I also tried to start to make these winglets locally, because it was very expensive to bring them in SA.
Unfortunately for more than 3 years I was unsuccessful in that.
Likely now we found the right company which make a copy these wing.
And I am proud to say that these winglets are better than original: they are abut 100 gram each lighter and quality and
finish is better.
2. The winglets give more stability on high speed in bumpy conditions.

Seems we have conflicting views here gents....

1: Do you need a CAA Mod Approval or not? Can we get some feedback directly from Braam/Willem please Alex Rudd? If so what is the process....(and how big is the headache? )

2: Jenya, what is the process when de rigging the wing for transport? How difficult is it to take the winglets off and then re assemble at your destination?

Must say they really do look good on a trike...bit of speed/stability and some "bling" factor too.

I cannot see how this would NOT require a mod approval chaps...you are changing the flight characteristics by fitting them?

[quote="Jenya"]Winglets to increase stability in bumpy conditions.
Also to speed up your plane for 5-10 mph.
Can be fitted for any type of the trike wings used in SA
Any device that will increase stability in turbulence works for me
Whatever documents/report/ authorisation is needed, so be it. As soon as we can have confirmation, and stock is available, I will install them

When I had mods done to my aircraft about nine months ago RAASA advised me in writing that modification reports were no longer required and that an entry in the aircraft logbook signed off by the AP was now sufficient.

I'm not sure if that ruling has subsequently changed.

Cheers, John

Regards,

Winglets are connected to the sail only by 2 stainless steel 6 mm pins with safety rings for each winglet.
It will take 1 minute to take winglets off the wing.

Chaps, according to CAA you need to submit a Mod Application.

I recommend contacting Braam Hechter at CAA for the correct process.

As I asked before, "Do I need a mod report?" I would imagine so...but RAASA and the CAA must confirm the requirement. Also, if a mod report is required only one mod report will be required per wing type. Once approved the mod can be done to any wing of the same type without additional reports.?

Hi Paul,

This is the response I received from RAASA when I had some recent modifications done (highlighted/bolded for emphasis):

Modifications 44.01.10

(1) If a person intends to carry out any modifications, including changes to equipment or the installation thereof, which affect, or are likely to affect, the serviceability of the aircraft, or the safety of its occupants or any other persons or property, in relation to an amateur built aircraft or a production built aircraft –
(a) in the case of a minor modification a notification of the modification must be submitted to the Director, or the organisation designated for the purpose in terms of Part 149, as the case may be, within 30 days of the modification being performed. All subsequent modifications shall be an amendment to the build standard;
(b) in the case of a major modification an application for the approval of the modification and authority to fly, as prescribed in Document SA-CATS 44, must be submitted to the Director or the organisation designated for the purpose in terms of Part 149, as the case may be, before the modification has been performed.

(2) The application referred to in sub-regulation (1) must be accompanied by the appropriate fee as described in Part 187.

(3) All approved modifications shall be entered into the appropriate logbook(s).

(4) An appropriately rated approved AMO, AME or approved person, rated in accordance with Subpart 4 of Part 66 shall sign in the appropriate logbook(s) that all procedures, as stated in the application for modification, were adhered to and that he or she is satisfied with the quality of the work which was carried out.

Once the notification has been received it is placed on file. There is no formal certificate issued from RAASA, however a release to service can be completed by the AP or yourself.

Hi
Will this be a minor mod, or major mod. that seems to be the question?
Fly safe.
