< Back Alert A-05-2025 - Alpi Pioneer 300 - Inspection of Undercarriage Components for Cracking and Corrosion 12 Jun 2025 LAA Alert A-05-2025 - Alpi Pioneer 300 - Inspection of Undercarriage Components for Cracking and Corrosion LAA Alert A-05-2025 has been published on the LAA website (and is also attached), highlighting Alpi Pioneer 300 and 300 Hawk aircraft that have suffered different malfunctions and failures of various components that make up the undercarriage. This Alert strongly recommends a close inspection of the undercarriage at 25-hour intervals for corrosion and cracking, as well as a retraction check, to verify that the retraction system components remained correctly adjusted, to avoid undercarriage collapse due to the mechanism not being adequately over-centre when extended.

Aircraft Carpentry Workshop - Basic Course Price Member - £206, Non-Member - £226 Duration Arrival 09:00. Finish 17:00. < Back About the Course Alan James brings a host of carpentry skills to this course, gained from building and maintaining wooden aircraft for more than 30 years. He is probably best known for his award winning Pietenpol Aircamper G-BUCO and more recently the Isaacs Spitfire G-ISAC. He’s also hand-carved more than 100 propellers for LAA and vintage aircraft over the years and is often seen demonstrating the art at the LAA Rally. His aircraft carpentry course covers everything the prospective builder needs to know. Subjects include quality and specification of approved timber, plywood, adhesives and how to use them, marking out, cutting, drilling, laminating, shaping, sanding, scarfing and finishing. As an LAA Inspector, he can also guide you through the paperwork process for repairs and modifications. This is the perfect course for the would-be aircraft builder who may be nervous about cutting the first piece of spruce, or anyone contemplating repairing a classic wooden aircraft. It is recommended that you bring your own protective glasses. Your Instructor Alan James Dates 2 December 2025 Times Arrival 09:00. Finish 17:00.

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

< Back The New Permit Revalidation System 28 Feb 2025 As the weather improves and the days grow longer, the flying season is just around the corner. Although you may already be thinking about all your usual flying preparations, there is one extra exciting update Owners and Inspectors alike should keep in mind this year: the launch of the new Permit Revalidation System. A flow chart of the new Permit Revalidation Process This new system will be fully online, and submission of your revalidation application will be via the LAA website under the “My Aircraft Details” section. Therefore, before arranging for an inspection this year, please make sure you can access your LAA member page. You can do this by going on www.lightaircraftassociation.co.uk and clicking on the Login button at the top left of the page and checking that your aircraft details are correct. If you have any issues with your login or aircraft details, please contact the LAA Office on 01280 846 786 or via email at [email protected] Screenshot showing where to login on the LAA website Screenshot showing the ‘My Aircraft Details’ button once you have logged into the LAA website Screenshot showing the button to start apply of your Permit to Fly Revalidation in the ‘My Aircraft Data’ area Applying for revalidation under the new system will be straightforward. Aircraft owners will begin the process by selecting their Inspector. Once selected, the Inspector will be notified that an application is awaiting their attention. After the Inspector submits their airworthiness review, the Owner will be prompted to pay for the revalidation, at which point the application will be sent instantly to LAA Engineering for issue. We are also planning to reduce the requirement for a check flight from one to three years for most aircraft types. However, Inspectors will also have the flexibility to request a check flight as part of the revalidation, if deemed necessary. Additionally, once the new system has launched, Inspectors will be able to issue PFRCs up to two years past the expiry of the Certificate of Validity. Please note, these changes, along with the new check flight cycle, will take effect only once the new system is officially launched. As we get closer to launch in April, more guidance, including a video and notes, will be shared with Owners and Inspectors, ensuring a smooth transition to the new Permit Revalidation System. Stay tuned for more! Next Previous

< Back New LAA Alert for all Rotax 900 series engines 13 Dec 2024 The LAA has issued Alert A-04-2024 – Highlighting loose and broken engine mounting bolts on Rotax 900 series engines A recurring problem with Rotax 912/914 engines, equally applicable to the newer 915 and 916 models, is of the four M10 bolts that attach the engine’s crankcase to the engine mounting frame becoming loose in service. Most manufacturers call for the bolts to be wire-locked in place. However, in the case of the Rotax engine mounting bolts, it seems that the bolts are coming loose not because the bolts are undoing and backing off on their threads, but because of the joint faces become imprinted over time through creep, corrosion or fretting, allowing the tension in the bolt to be lost and the joint to become loose. These problems in the field are a reminder that where it’s critical that a bolt be torqued up, this should be checked at intervals (at least annually, we’d suggest) by undoing the locking and re-torquing them, before replacing the locking wire. Be sure this check is included in your aircraft’s maintenance schedule. DO NOT RELY ON A BOLT BEING WIRE LOCKED TO BE SATISFIED THAT THESE CRITICAL BOLTS ARE STILL TIGHT.
