Operating & Maintaining Aircraft This section is intended to cover everything that happens once the aircraft is in a flying state. From a technical point of view, the most import of these is keeping on top of the aircraft’s maintenance. This is critical in enabling an owner to meet their obligation to maintain the aircraft in an airworthy condition.

< Back New LAA Inspector - Sam McMellon 22 Oct 2024 The LAA is pleased to welcome Sam McMellon as a new LAA Inspector for Factory Built Gyroplanes. Sam attended an Assessment Day at LAA HQ with our Chief Inspector earlier this month. Well done Sam! 🎉 Next Previous

< Back LAA members - Make your views known! 25 Jan 2024 Basingstoke & Deane Borough Council's consultation on their draft Local Plan – which includes a proposed new Popham Garden Village on Popham Airfield, has opened. It runs until 4 March 2024. This proposal is not in line with either Government policy or their stated aim to make the UK the best place in the world for General Aviation. The Government's policy can be found in their publication ' Flightpath to the Future " and makes repeated references to the vital importance of airfields, forming a critical part of national infrastructure. You can have your say and tell Basingstoke & Deane Council that their proposal is contrary to Government policy and insist the proposal is removed from the current ‘draft’ strategic plan. Visit the Local Plan Update ' Have Your Say ' section of their webiste. Next Previous

Over the years this has led to several commercially successful kitplanes (Europa, Streak Shadow, Sherwood Ranger), as well as designs that have been released for plans-building (Flitzer, Isaacs Fury, FRED) and a whole range of fascinating on-off personal aircraft – the Acro Advanced, Bonsall Mustang, Mickleburgh Sparrow to name just a few. There will always be LAA’ers keen on the ‘retro’ look, but with ever-increasing fuel costs we foresee a greater emphasis in future on aircraft exploring higher efficiency, alternative powerplants (electric?) and renewable materials. High hangarage fees mean that aircraft enthusiasts are more than ever interested in folding or de-riggable aircraft that can be kept at home. Using the information provided by clicking the links below, the LAA hopes to stimulate interest in light aircraft design, help potential designers through the process and encourage the development of high quality designs. With the decline in UK manufacturing over the recent decades, it seems more than ever important to keep alive a thread of creativity and enthusiasm for design and development. For some, the ability to bring a personal design from first concept to a flying prototype provides the ultimate source of satisfaction within the LAA scene. Designing Aircraft Since its formation in 1948, one of the stated aims of the LAA has been to encourage the designing and building of new types of light aircraft. For our own purposes, we in LAA Engineering have been producing a series of Excel spreadsheets to use as tools in the verification of calculations in the many aircraft design submissions we deal with. The spreadsheets have been designed to carry out the various calculations that are necessary during the design of light aircraft. Some of them have been written against specific paragraphs in the design code CS-VLA, whereas others, for example, cover areas related to the development of aircraft undergoing flight testing. In addition, simple spreadsheets for straightforward mathematical calculations have been written. It is for information and educational purposes that these spreadsheets are now available to LAA members on the LAA web site. Use the buttons below for more information on each design stage: Preliminary Design Detail Design Certification/Approval

LAA are proud to announce our Rally 2025 sponsors Trophies & Awards A number of prestigious Trophies and Awards are judged at the Rally, recognising the many superbly built and restored aircraft that attend. If you would like to enter your aircraft for judging you can do so on arrival. The judging team will be co-located with booking-in. You can, however, download and complete the entry form beforehand. The list of the awards for 2025 can be found here . Complete list of award can be found here . Judging guidelines can be found here . Factory built aircraft less than 35 years old are not eligible. The judging team will ensure you are in all competitions for which you are eligible. The judges sometimes have difficulty finding an aircraft. Owners are therefore urged to download the free`What3Words’ app and use it to show their aircraft’s location when registering. All pilots who wish their aircraft to be judged are asked to display to the marshallers the large J found here . They will then direct you, if possible, to a convenient parking space. Please leave the 'J' visible in the windscreen to help the judges find your aircraft. Judging takes place from 13:30 to 17:00 on the Saturday; therefore, all entries must be received by 13:00 on Saturday.

< Back Alert A-04-2025 - Jabiru Flywheel Bolts 12 Jun 2025 LAA Alert A-04-2025 - Jabiru Flywheel Bolts LAA Alert A-04-2025 has been published on the LAA website (and is also attached), highlighting the Installation Procedure, Torque Checks and Replacement Interval for Flywheel Attachment Bolts on aircraft equipped with Jabiru 2200, 3300 and 5100 engines, and withdrawal of LAA Alert AWA/20/15. With the advice in JSB-012 (Issue 9 onward) having been promulgated by Jabiru, LAA has withdrawn Alert AWA/20/15, which means that provided the advice in JSB-012 Issue 9 or subsequent is followed, along with regular bolt torque checks at every 100 hours and annual check as called for in the Engine Maintenance Manual, the recommended bolt life is as stated in the Engine Maintenance Manual (currently 500 hrs). For LAA aircraft having the flywheel bolts replaced, or torque checked, the work must be overseen and signed-for by a suitably approved LAA Inspector. Engine logbook entries must be made and certified with a PMR statement referencing JSB-012 in the logbook white pages, as well as an entry in the logbook pink pages (or equivalent method for tracking continued airworthiness compliance).

< 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.
