< 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 Alert 05-2024 - Rotax Oil Spray Nozzles - upissued to Issue 2 24 Jul 2025 LAA Alert 05-2024 - Inspection and/or Replacement of Oil Spray Nozzle in some Rotax 900 series engines - upissued to Issue 2 On 16.12.24, Rotax issued a MANDATORY Service Bulletins SB 912 i-016/SB 915 i-016 / SB 916 i-006 and SB-912 i-016iS / SB-915 i-016iS / SB-916 i-006iS which call 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. Therefore, LAA Alert A-05-2024 was issued on 17th December 2024 regarding this. Subsequently, a revision to the Rotax Service Bulletins was issued on 20.12.24, entitled MANDATORY Alert Service Bulletins ASB 912 i-016 R1/ASB 915 i-016 R1 / ASB 916 i-006 R1 and ASB-912 i-016iS R1 / ASB-915 i-016iS R1 and ASB-916 i 006iS R1. Therefore, on 23rd July 2025, LAA Alert A-05-2024 was upissued to Issue 2, which now supersedes Issue 1. A-05-2024 Issue 2 can be found HERE and is also found below. 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.

< Back Gyroplanes to join the new online Permit Revalidation System 17 Jun 2025 The new online Permit Revalidation system has been in place for fixed-wing aircraft on the LAA fleet since 15th April 2025 and now it is time to add Gyroplanes, both amateur-built and factory-built. Therefore, we are pleased to announce that gyroplane Owners and Inspectors will be able to use the online Permit Revalidation system from 22nd July 2025! The Permit Revalidation Process for gyroplanes will follow the same three steps as for fixed-wing aircraft, shown in the graphic below. The only differences will be small changes to the questions in line with the requirements for gyroplanes, such as asking about the rotor and rotor-head. Where do I find more information? If you are a Gyroplane Owner or Inspector, then please talk to your friends that own and inspect fixed-wing aircraft, as many of them will have been through this new process. There is lots of information to help you: Technical Leaflet 2.00 – Revalidating an Aircraft’s Permit to Fly , will be updated on 22nd July to include information regarding gyroplanes A detailed step-by-step video guide is available on the LAA’s YouTube channel, called ‘ Online Permit Revalidation Explained .’ A list of Frequently Asked Questions is available on the LAA website. Again, these will be updated on 22nd July to include Gyroplanes For more information, click HERE . Note: the 22nd July is a hard deadline, so LAA Engineering will not accept applications made under the old system from that date. Changes to Permit Revalidation Fees for Gyroplane Owners From 22nd July, Permit Revalidation Fees for gyroplanes will be based on Maximum Take Off Weight (MTOW), rather than Factory Built Gyroplanes always having a fee of £323. This is in line with the charging regime for fixed-wing aircraft. The current charges are as follows: Up to 450kg - £241 451-999kg - £292 1000kg & above - £323 Note: For FBGs - if the last Permit revalidation was not administered by the LAA, an extra fee of £155 applies Next Previous

< Back LAA Alert A-14-2025 - Eurofox Fuel Line Disconnected In-Flight 11 Dec 2025 LAA Alert A-14-2025 - Eurofox Fuel Line Disconnected In-Flight A non-LAA, Factory-Built Eurofox with a Rotax 915, fuel-injected engine experienced an in-flight engine shut down due to the high pressure (4.5 Bar) fuel hose connecting the high-pressure fuel pump unit to the master fuel valve becoming detached from the master fuel valve during flight. This resulted in the engine stopping and a serious fuel leak in the cockpit. It is believed that a combination of the fitting’s shallow barbs, and a small fuel leak of high-pressure fuel through the scratched/cut hose lubricated the fitting’s brass surface and allowed the hose to slide off the fitting. Owners and Inspectors should pay close attention to fuel hose condition and attachment security during inspections. Any signs of movement, wear, or mismatch between hose and fitting must be addressed before the aircraft flies again. Please refer to the attached Alert here for full details and recommended checks.

< Back LAA Alert A-15-2025 Glasair Rudder Pedal Bearing Failures 23 Dec 2025 LAA Alert A-15-2025 Glasair Rudder Pedal Bearing Failures A recent social media report has brought attention to two rudder pedal bearing failure events on a non-LAA Glasair. These bearings attach each rudder pedal assembly to the bearing support ribs. Owners and Inspectors should carry out frequent inspections of these bearings for signs of cracking, breaking, excessive play or any other abnormalities. Pilots should also conduct effective full-and-free movement checks during taxiing to ensure correct rudder pedal operation prior to take-off. If there are any doubts on the bearings’ condition, age, or origin, they should be replaced with newly made ones. Instructions on how to make new bearings from a 3/4" UHMWPE sheet can be found in the Stoddard-Hamilton Instruction Manual. Please refer to the LAA Alert A-15-2025 HERE or below for full details and recommended checks. A-15-2025 Glasair Rudder Pedal Bearing Failures .pdf Download PDF • 309KB Next Previous
