< 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 MTD-03-2025 - Marquart Charger Aileron Slave Strut 25 Jul 2025 LAA MTD-03-2025 - Marquart Charger Aileron Slave Strut The starboard aileron slave strut on Marquart Charger G-BHBT failed at the AN490 threaded fitting welded into the bottom end. A large proportion of the cross-section was cracked due to fatigue prior to final failure. The root cause of the fatigue cracking was probably flutter. Due to the difficulty of reliably inspecting for fatigue cracking at the base of threads, it has been decided to withdraw this strut design from the UK fleet.

< Back MTD-05-2025 Issue 3 published - Eurofox Rudder Pedals 7 Jan 2026 MTD-05-2025 Issue 3 has been published to provide further information on the situation as it develops and asking Owners and Inspectors to report back. The inspection schedule in unchanged from Issue 1 or Issue 2. Therefore, Issue 3 does not require you or your Inspector to do anything different. If your aircraft has already been inspected to MTD-05-2025 Issue 1 or Issue 2, then the next time an inspection in accordance with the MTD is due, you Inspector should reference Issue 3 in their logbook entry. LAA is continuing to work towards achieving a permanent solution via a modification to the rudder pedal/torque tube design.

< Back The online Permit Revalidation System is live for Gyroplanes! 22 Jul 2025 We are pleased to announce that the online Permit to Fly revalidation system went live today for gyroplanes, both home-built and factory-built! Step-by-Step Video Guide, FAQs and Crib Sheet The step-by-step guide to the new online Permit Revalidation system in the form of an ‘ Online Permit Revalidation Explained ’ video can be found below. This was written for a fixed-wing example, but the majority of questions are the same for gyroplanes and the process for gyroplanes has the same three stages as for any fixed-wing aircraft. We have also compiled a list of ‘ Frequently Asked Questions ’ for you, which are found below. The ' Crib Sheet ' for Inspectors referenced in the video is formally called the ' Airworthiness Review Reference Guide ' and is available HERE . There is a version of the crib sheet for homebuilt gyroplanes, entitled ARR-REF (HOMEBUILT GYROPLANE) and a version for factory-built gyroplanes, entitled ARR-REF (FB GYROPLANE). The Check Flight Schedules for both homebuilt and factory-built gyroplanes have now been combined into a single check flight schedule for gyroplanes, entitled CFS-1 (GYRO). This is available HERE . Previous check flight forms for homebuilt and factory-built gyroplanes are now obsolete. The Permit Flight Release Certificate (PFRC) is now a separate document, where it was previously contained within the application form for revalidating a Permit to Fly. It can be found HERE . Key Considerations There are a few key considerations to ensure a Permit to Fly revalidation under the new system goes smoothly: Please make sure you know your username and password for the LAA website. If you have forgotten your login details, please contact the LAA Office. All aircraft using the new system for the first time will require a check flight no older than 3 months at the time of submission of the revalidation application. This is in order to provide a baseline for the online system. The 3-year check flight cycle will then apply subsequently to most aircraft types. Some aircraft will still require a check flight at every revalidation, these are: Aircraft cleared for Night/IFR. Aircraft which have flown less than 12 hours since the previous revalidation inspection. Aircraft Owners will not have to submit a CFS-1 (GYRO) Check Flight Schedule when applying through the new system. However, a CFS-1 (GYRO) will need to be completed for each check flight and stored with the aircraft’s documentation, so that it is available when needed. We will no longer be accepting old-style (paper or scanned) Airworthiness Reviews for homebuilt or factory-built gyroplanes conducted on or after 22 nd July 2025. Need Help? The ‘Revalidating a Permit to Fly’ page on the LAA website signposts you to all the information you will need and can be found HERE . If you have any problems or questions, please follow the steps below: Watch the ‘ Online Permit Revalidation Explained ’ video found HERE . Read Technical Leaflet 2.00 - 'Revalidating your Aircraft's Permit to Fly,' which has now been updated to include information for gyroplanes.

< 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 LAA Alert for Rotax 900 series engines regarding the oil spray nozzle 18 Dec 2024 Inspection and/or Replacement of Oil Spray Nozzle On 16.12.24, Rotax issued a new MANDATORY Service Bulletin SB 912 i-016/SB 915 i-016 / SB 916 i-006 which calls for urgent action for engines of specified models within certain serial number ranges, if the engine has run for less than 200 hours from new, or engines which have been fitted with specific overhaul kits supplied between 01.01.22 and 31.10.24 inclusive. The bulletin concerns problems with a possible full or partial blockage of the oil spray nozzle due to an excessive application of Loctite at the manufacturing stage, when assembling the sprag clutch housing. This can lead to inadequate cooling of the stator assembly, potentially causing loss of electrical power to the engine’s ECU.
