< 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

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.

< Back CAA MPD-2026-003-E – Rotax 912/914 Series Engines 6 Jul 2026 Propeller Gearbox Inspection (Rotax 912/914 Series Engines) Please note that the UK Civil Aviation Authority (CAA) has published Emergency Mandatory Permit Directive MPD-2026-003-E, which was issued on 30 th June 2026 and became effective on 07 th July 2026. The directive applies to Rotax 912 UL, 912 ULS, 912 iS Sport, and 914 UL series engines fitted with affected propeller gearboxes as defined in the MPD. The MPD mandates inspection of the affected propeller gearboxes due to a potential assembly process deviation that could result in oil loss and/or an in-flight engine shutdown. Please note for the most seriously affected engines mandatory action is required BEFORE THE NEXT FLIGHT. Please review the MPD to determine whether it applies to your aircraft or engine and ensure that the required inspection and any necessary corrective actions are completed within the specified compliance times. If you have an engine of one of the effected types, please note the pink pages of the engine logbook should have a new entry made for this MPD, either on the applicable or non-applicable page, as appropriate. The directive (MPD-2026-003-E) for your reference and can also be found HERE or below.

< Back Carbon Monoxide in Piston Engine Aircraft Consultation 22 Feb 2024 In recent years, the CAA has been actively engaged in raising pilot awareness of carbon monoxide (CO) in general aviation (GA) and has undertaken multiple initiatives to promote prevention and detection measures to mitigate the risk. We have now launched a public consultation seeking stakeholder views on: the barriers pilots face in obtaining an active CO detector, the role that maintenance plays in combatting CO, the importance of protecting passengers from CO, and whether active CO detectors ought to be mandatory for some operations. The consultation closes on 20 March 2024. We invite stakeholders to give us your views . Next Previous
