Modification & Repair Worklist Below is a list of modification and repair applications that are awaiting review by our engineers. The top of each list represents the next one in that list to be reviewed. Each engineer's workload is listed separately - engineers also have tasks that are not mods and repairs. New applications received in the last week are not shown and will be added to the relevant engineer's list shortly after allocation (allocation usually takes place each Tuesday). The lists are not currently real time, but will be updated at least weekly. Note that we operate a priority system that aims to put jobs involving accidentally grounded aircraft ahead of longer term projects - new or returning tasks may therefore be added above existing tasks. (last update 10/07/26) Please note that due to staff illness and, to a lesser extent, staff leave, unfortunately we have a larger backlog of work than normal at the current time. Thanks for your patience while we work hard to catch up.

< Back MTD-05-2025 Eurofox Rudder Pedal Cracking 19 Nov 2025 MTD-05-2025 Eurofox Rudder Pedal Cracking - Mandatory Inspection requirements, which must be completed before your next flight There have been two reported instances in the UK of Eurofox aircraft experiencing cracking at the right-foot rudder pedal on the starboard seat side, where it is welded to the rudder pedal torque tube, leading to the pedal no longer being rigidly attached to the torque tube. On at least one of these instances, aircraft handling was negatively affected, reducing yaw authority and seriously degrading flight safety. Note that failure of the starboard side right-foot rudder pedal results in loss of rudder control, even when the aircraft is flown from the Pilot in Command position i.e. from the port seat side. Please refer to the MTD-05-2025 document below for full details of the mandatory inspection requirements, which must be completed before your next flight and subsequently at intervals not exceeding 10 flight-hours or the next Permit Revalidation inspection, whichever occurs first.

< Back New LAA Inspector - Steve Hodge 4 Apr 2024 The LAA is pleased to welcome Steve Hodge as a new LAA Inspector. Steve came to an Assessment Day at LAA HQ at the start of March. Steve has been part of the aviation trade since 1997, when he joined Arrow Aviation Services as a trainee. He pretty much learnt his entire trade there and was very fortunate to have worked with a wide variety of components from engines and propellers, to wheels and brakes, with a lot of vintage aviation thrown in too. His is now as Owner and Accountable Manager of his own company, SOAR Aviation, a CAA Part 145 approved facility. He continues to provide the aviation industry with what he hopes is thought of as an honest, reliable, friendly and cost-effective service. He has always been involved with the LAA and enjoys serving the LAA community. 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.
