< Back Mandatory Technical Directive issued for Eurofox aircraft 6 Dec 2024 Inspection of Trim Tab Operating Cable Attachment to Prevent In-Flight Failures and replacement with Improved Design of Cable Attachment In 2016, the LAA issued an Alert, LAA/AWA/16/08 , regarding reported problems with the thin stranded steel elevator trim cable on Eurofox aircraft fraying at the attachment point to the trim tab operating horn, where the design forced the cable to be bent around the sharp edges of the clevis. The 2016 Alert also provided a link to, and served to promulgate, the Eurofox UK Service Bulletin on the subject, SB 04/2016 . Recently we’ve been advised of a potentially serious incident of elevator flutter on a Eurofox while towing a glider, which was caused by the trim cable failing altogether in flight where it passes around the trim tab operating horn clevis. This resulted in violent shaking of the elevator with serious potential for structural damage or loss of control. Since the cable had evidently frayed considerably before failing altogether, this occurrence highlights the importance inspecting the trim cable for signs of fraying at this point at each pre-flight and maintenance check, and, as the service bulletin explains, of keeping the clevis free-moving about its attachment to the tab so the clevis remains in line with the cable as the tab moves. This minimises the relative movement between the two which if occurring, would accelerate the wear on the cable. Eurofox UK advises that since the issue of the 2016 Service Bulletin, they have revised the design of the cable attachment clevis so that the cable now passes around a circular bush rather than being forced into two sharp bends, which reduces the wear on the cable and tendency to fray and eventually break. MTD-07-2024 , issued today, requires Owners/Operators to check whether the old or new design of clevises are fitted and for any signs of trim cable fraying before further flight. Owners/Operators must obtain and use a copy of the up-issued AEROPRO Checklist - B Service/Maintenance plan (Update Nov 2024 LAA aircraft) before the next 50-hour check. Finally, the trim cable system must be replaced immediately if any trim cable fraying is found, as detailed in the MTD. Furthermore, all Eurofoxes with the old-style of clevis must have the trim cable system replaced, as described in the MTD, by 1st June 2025.

We provide a system whereby members can build an aircraft in the comfort of their own home (or wherever they choose) from either a set of plans or from a kit of parts. Every year around 100 newly-constructed aircraft are added to the LAA fleet, with members generally taking around 1 to 4 years to complete their kit projects. A whole range of aircraft is available to build, from single-seaters to four-seaters, aerobatic to amphibian, and WWI replica triplanes to gyroplanes. The LAA is tasked with ensuring that the designs members build meet minimum airworthiness requirements, appropriate to the type. Proposals for accepting other designs of aircraft can be put to the LAA, and a number of such types are accepted each year following a review of their airworthiness, amongst other things. This requires a member to champion the type through the process, arranging for the necessary technical information to be passed to the Engineering department and to build and test the first example. Similarly, it is possible for a member to build an aircraft of their own design. LAA provides support for this (see the Designing aircraft section), but due to limited resources only the most promising/developed designs can be advanced through the system. Building Aircraft One of the founding principles of the LAA is to provide for members wishing to build their own aircraft, either for their own education or to enable them to own an affordable aircraft. Of course, whichever type you choose it is usually possible to customise it to your liking using the LAA’s modification system. So if it’s an elaborate avionics suite that takes your fancy or an automotive engine conversion, there’s a route to investigating whether it’s possible. If you like the idea of building, but feel you lack the skills, then there are courses on various aspects of aircraft building to help bring you up to speed. Your Inspector is also a fantastic mine of information and generally will be your first port of call for technical information. Of course, the LAA also has a pool of full-time engineers who can be contacted for advice.

Detail Design Having worked out a promising-looking layout, initial three-view and performance and weight specifications, now is the stage where the hard work begins of transforming concepts to working drawings. Essential decisions have to be made about types of material to be used, the structural arrangement, exact choice of powerplant and so on. You’ll probably need to make a cockpit mock-up to check the ergonomics and control system arrangements, and maybe build a flying radio controlled model of the design to give faith in the handling characteristics. With the basic geometry laid out, stress calculations and assembly drawings come next, then drawings of individual piece parts. Keep an up-to-date tally on weights. As the drawings get more detailed you must re-evaluate whether you are going to meet your original targets in terms of weight, strength and aerodynamic cleanliness, whether you need to re-visit your original assumptions or re-design from scratch. Is there a way that the part or assembly can be made more easily, more cheaply, lighter, stronger, more fatigue or corrosion resistant? Fewer parts and fewer joints generally means fewer problems and less weight. Can you use off the shelf parts rather than having to make them specially? Are there other aeroplanes around that have already solved a particular problem in a clever way? Will the aircraft be easy to inspect in service, easy to repair if it gets damaged? Can it be broken down for transportation? If the handling isn’t quite right when the prototype is test flown, does the design make provision for ‘tweaks’ to put it right? Does the design include reserves of strength to cope with weight growth in service and more powerful engines, or is everything pared down to the minimum? Design Tutorials

The Annual General Meeting of the Light Aircraft Association Ltd Old Warden Aerodrome Airfield of The Shuttleworth Collection Bedfordshire 20th October 2024 N otice is given that the AGM of the Light Aircraft Association (LAA) will be held in the Discovery Hub, Old Warden Aerodrome, Biggleswade, SG18 9EP at 12Hrs on Sunday 20th October 2024. Nominations for Board Directors and Notices of Motions of any kind for the AGM must be received at LAA HQ, no later than Sunday 8th September 2024. Nominations must be signed by both proposer and seconder, both of whom must be beneficial shareholders. In respect of nominations to the Board of Directors, candidates must have been a beneficial shareholder continuously for at least two years and include a signed statement indicating their willingness to serve as a Director, should they be elected. The AGM will provide for both in person and remote on-line participation. These arrangements will be professionally administered. In addition, those unable to attend may elect to submit proxy votes. A full list of nominations, Motions together with the proxy voting form will be published with October’s Light Aviation and on-line via the LAA website. The AGM will be pre-ceded by the presentation of LAA Service, Rally Trophies and Awards to members. Following the AGM there will be time reserved for a Member’s Forum for discussion and Q&A on general matters with the Board and CEO. Light refreshments will be available upon arrival and lunch will be available to purchase in the Shuttleworth cafe. Provision will also be made for members to fly-in and visit the Shuttleworth museum and gardens – full details of which will be published in due course.
