< 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.

< Back Mandatory Technical Directive issued for Pioneer aircraft 6 Mar 2024 The control horn on the elevator trim tab on a Pioneer 300 failed in flight, which resulted in sever trim tab flutter. A safe landing was made and there was no further damage to the aircraft. MTD-02-2024 requires the checking of this horn on all Pioneer variants to ensure that it is of the correct design standard and recommends regular checks for free-play in the system. Next Previous

< 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 Mandatory Technical Directive issued for Sting S4 29 Sept 2023 LAA has been working with TL StingUK to correct an issue found during the flight testing of the factory-built version of the aircraft. It was found that the type would consistently drop the starboard wing more than the permitted maximum during a wings-level stall. LAA Mandatory Technical Directive MTD-01-2023 has been issued that requires the installation of a stall strip on the starboard wing and two stall strips on the port wing, along with restricting the elevator travel, in accodance with TL StingUK service bulletins 0002 and 0003, before further flight.

< 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.

Jabiru Engine Course Price Member - £213, Non-Member - £233 Duration Arrival 09:00. Finish 17:00. < Back About the Course It is widely accepted that a good working knowledge of an engine will help a pilot to service and maintain it to a satisfactory standard. This course is designed to give pilots sufficient knowledge to be confident that their engines are both serviceable and airworthy and; if an issue is detected, to know whether they have the ability to resolve the issue or need to seek assistance. The course will also cover the common engine weaknesses and the important Jabiru modifications. The course primarily focuses on the 4 and 6 cylinder generation 1-3 engines. The course will also benefit owners of the latest generation 4 engine, but information will be limited due to the overall hours flown to date for this type of engine. The Aim of the Course The aim of the course is to give Jabiru engine operators sufficient knowledge to maintain and operate their engines. Method A classroom slide presentation will be given , supported by a demonstration engine and parts, detailing the build of a Jabiru engine from the crankshaft up. The slide presentation will also use the knowledge gained from the virtual build and cover how to check for engine serviceability prior to flight. Course Instructor: Clive James. Clive has owned and operated a Jabiru for over 20 years and in that time has worked on many engines, including 4 and 6 cylinder engines. Clive also provides technical assistance to many Jabiru engine owners, helping them maintain their engines to an airworthy standard.

< Back More new LAA Inspectors - Patryk Nelkowski & Pete Nicholson 2 Feb 2024 It is time to introduce you to two more new LAA Inspectors - Patryk Nelkowski and Pete Nicholson, who both attended an LAA Inspector Assessment Day in January, with our Chief Inspector, Lucy. Patryk is a UK CAA licensed aircraft engineer (B1.1/B1.2/B3) based in the south west of England. Currently in the Greater London area on Pilatus, Cirrus and Tecnam aircraft as part of his day job. He has a wide-ranging aircraft maintenance background, with experience on commercial aircraft, such as the A220, Dash 8, and Embraers right through to Cessnas, Pipers, RVs and a variety of other aircraft including warbirds. In his spare time, he is involved in the maintenance and restoration of classic cars and historic military vehicles and their engines. After studying an engineering degree, Pete's professional career covered a wide range of electronic and communications systems, during which flying and maintaining both powered aircraft and gliders was a passionate hobby. After being lucky enough to take early retirement, his hobby has become a significant part of his activities and he particularly enjoys using his background and experience to work on Avionic systems.
