< 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. https://www.youtube.com/watch?v=rOGRQ89dOA8 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. Look at the gyroplane variants of the 'crib sheet' for LAA Inspectors, entitled ' Airworthiness Review Reference Guide ,' which is available HERE . Look at our list of FAQs ,.

< Back LAA Alert issued for Lycoming Engines 28 Nov 2024 The LAA has issued Alert A-02-2024 (link below) to highlight the recent Lycoming Airworthiness Directive regarding connecting rod bushings and connecting rod assemblies. The FAA has issued a new airworthiness directive (AD) for models of Lycoming engines that have an affected part installed and are assembled within the ship date range, as specified in Table 1 to paragraph (c) of this Airworthiness Directive (AD 2024-21-02). The AD comes into effect on 5th December 2024. This AD was prompted by several reports of connecting rod failures which resulted in uncontained engine failure and in-flight shutdowns. The AD requires repetitive oil inspections for bronze metal particulates at each oil change, and if found, additional inspections of the connecting rod bushings for damage, proper fit, movement, and wear, and replacement if necessary. The first oil inspection must take at the next oil change or within 4 months after the AD becomes effective i.e. 5th April 2025, whichever occurs first. As terminating action to the connecting rod bushing inspections, this AD requires replacement of the connecting rod bushings with parts eligible for installation.

< Back LAA System Update - 9 Oct 9 Oct 2024 9th October 2024 We are now up and running! Many apologies, once again, for the inconvenience caused and thank you for your patience. You may notice a few changes which are aimed to make the system more user friendly. Regards LAA Team 8 Oct 12:30 Due to an unexpected problem, our system is still in maintenance mode whilst they work on it. We apologies for the inconvenience this is causing and as soon as we are back on line, we will send an email out to members to advise them the site is live. 7 Oct - 15:35 Unfortunately it’s taking a lot longer than expected to update our systems and we are still in maintenance mode. Hopefully we should be ready to go live later on this afternoon. 4 Oct We will be upgrading our software which runs our membership and engineering databases on Monday 7th October. This will mean that our system will be put into maintenance mode at about 7.30 am and should come online again around midday. It will have an impact on accessing the membership renewal area, LAA online shop and your aircraft details. We apologies in advance for the inconvenience. Next Previous

E10 Mogas From 1st September 2021, the government mandated that all regular grade unleaded petrol must contain up to 10% ethanol, rather than up to 5% as previously. In the autumn of 2021, most filling stations around the UK re-marked their E5 petrol pumps to show that they now supply E10 specification fuel, and started receiving tanker-loads blended with up to 10 percent ethanol content. For the automotive world this means reduced carbon dioxide emissions, which is better for the environment, and, arguably in terms of eco-desirability, a small further reduction in the reliance on fossil fuel. The automotive industry had been preparing for this change, and people with road vehicles registered after 2002 should be able to switch to E10 without noticing any difference. Unfortunately, the additional ethanol content is bad news for aviation users if we were to ignore the change and start putting E10 in our aircraft regardless. Ethanol is a powerful chemical solvent which can attack components including rubberised gaskets and fuel pipes, older lacquered carburettor floats and composite or plastic components in some newer fuel systems. The doubling of the concentration of ethanol in E10 compared to E5 makes it much more likely that problems will be experienced if these parts are not designed to be ethanol-proof. Ethanol also has an affinity for absorbing water, which over time can then become acidic, attacking metal components in the fuel system and engine. Even if there was a practical way to do so in the volumes of fuel we use in our aircraft, we cannot safely remove the ethanol content from the fuel because the ethanol acts as an octane enhancer, so the washed-out fuel would be left with a reduced octane value, likely to cause detonation problems. Another issue is that ethanol-blended fuel has a lower energy density than petrol, so to develop full power from our engines using an E10 fuel, we may need to richen the fuel/air mixture, for example using a bigger carburettor jet size. Owners of Rotax and Jabiru engines are probably already aware that many of these engines are supplied as being able to use E10 fuel – though with Jabiru engines, in particular, it’s far from straightforward because some of the earlier engines require cylinder head modifications and reduced compression ratio if they are to avoid detonation issues when using any form of Mogas. Jabiru also say that Mogas of any type should not be used in commercial flight schools and only at the owners own risk. Even with a supposedly E10-compatable engine, the chemical compatibility problems with fuel system components are such that the LAA does not at present approve the use of E10 Mogas in any LAA amateur-built or vintage aircraft. For factory-built microlights and factory-built gyroplanes, where LAA is not the approving authority but only renews the CAA’s Permits to Fly, owners need to refer to the TADS for the types for details of the approved fuel types, and monitor the service bulletins from the approved manufacturers for news of any updates. Where we need to be particularly careful in reading-across from (hopefully) a trouble-free transition to E10 in automotive use is the big difference between our petrol cars and the way our aircraft engines are configured. Our cars generally have submerged fuel pumps in their petrol tanks and a sealed fuel system. In our aircraft we have an open-vented tank and usually a fuel pump several feet away, often mounted in a hot area of the engine bay near to the engine exhaust, dragging the fuel through a fairly convoluted pipework system, a filter and fuel selector – all features encouraging a vapour lock - and then to make matters worse we want to climb up to altitude and operate in reduced atmospheric pressure. Modern petrol cars have a fuel injection systems rather than carburettors, a circulating fuel system designed to purge any vapour forming in the fuel line, and an ECU that monitors the engine’s parameters constantly and adjusts the fuel mixture strength and ignition timing to prevent damage to the engine – and if all else fails and the engine should ‘pink’, we can hear it from the driver’s seat and drop a gear to lighten the load. Because of the much higher background noise level in our aircraft, detonation cannot be heard and the pilot’s first indication of a problem may be when the first piston crown disintegrates, or a valve head departs its stem. In conclusion - E10 is presently not approved for use in any LAA aircraft. ‘Hoping for the best’ and using E10 fuel in your aircraft regardless could risk ruining the fuel system components, fibreglass tanks falling to bits, engine failure through contamination of the fuel or ruptured fuel pump diaphragms etc, or more serious engine damage. For most of our engines, UL91 Avgas is the best choice, but 97 octane E5 Super Unleaded remains an alternative to the now-obsolete E5 spec Mogas.

Continuing Airworthiness Information One of the key strengths of the LAA's system is that we can monitor the fleet centrally and keep track of airworthiness incidents from around the world. Where necessary, we can then let our owners know, to help them keep flying safely.
