< Back MTD-06-2025 published - Europa Tailplane Torque Tube Mod Failure 16 Dec 2025 Ref: LAA Mandatory Technical Directive MTD-06-2025 – Europa Tailplane Torque Tube Clamp Mod A recent inspection of a Europa fitted with the tailplane torque tube clamp modification, LAA MOD 10623, revealed both halves of the clamp had broken and fallen apart. These clamps are intended to prevent relative movement between the tailplane torque tube, the tailplane drive plates and the central drive horn, on which the mass balance arm is mounted. Failure of these clamps could allow free play to develop, potentially leading to taper pin hole damage, tailplane flutter, or jamming of the pitch control mechanism. An inspection must be carried out within the next 5 flying hours to determine whether MOD 10623 is fitted. If MOD 10623 clamps are fitted, making use of a light source and mirror as necessary, inspect the alloy clamp blocks for any signs of cracking (in particular along the sharp corner between the bolt flanges and main body), for any signs of looseness or relative movement between the parts and for any other abnormalities. If any of these are detected, the aircraft must not be flown and LAA Engineering must be contacted. This must be repeated at intervals not exceeding 25 flight-hours or the next Permit revalidation inspection, whichever occurs first, for as long as MOD 10623 remains fitted. Please refer to the below Mandatory Technical Directive for full details, compliance times, and certification requirements. This MTD can be found HERE and is also available below.

< Back Replica De Havilland DH71 Tiger Moth Racer takes to the air 23 Dec 2024 Steve Jones’ replica DH71 Tiger Moth Racer made a highly successful maiden flight on 26th November, piloted by Steve himself. The immaculate monoplane, appropriately registered G-ECDX, is a full-size recreation of one of only two examples built by de Havilland in 1927. Of all wood construction, and fitted with a modified DH Gipsy 1 engine, the original DH71s were created to publicise their new Gipsy engine before releasing it onto the market to power their already successful DH60 Moth biplane. An exercise in light weight and streamlining to maximise speed, the DH71 was also significant in developing construction techniques that de Havilland used to good effect in later designs. The original DH71 achieved 186mph around a 65 mile closed circuit course, its Gipsy 1 engine souped-up from 85 to 130 horsepower for racing. The replica project was largely built by Ron Souch in the 1990s, under PFA supervision, using drawings produced by Ron’s friend Ben Price, a former aircraft draughtsman who put forward the idea as his retirement project. None of the original construction drawings had survived, so the design had to be recreated based on a three-view, photographs, press articles and intimate knowledge of de Havilland’s standard design techniques – and then checked against modern design code requirements. Most challenging part of the design were the details of the internally bungee-sprung wheels, as on the original. The project was paused for several years after issues came to light with the stressing of the wing spars and undercarriage. Steve Jones, looking for a hangar-mate for his scratch-built Comper Swift project, purchased the DH71 in 2016. Steve quickly got things moving again by commissioning re-designs of some of the original components, stripping off the fabric covering, re-sparring the wings and finishing the aircraft off to the same high standard as its original construction. The final examination of the assembled aircraft by LAA HQ’s design staff in November, when ground runs of the modified engine and its very coarse pitch Hercules propeller were demonstrated, took place over three decades after the project’s inception. When Steve’s replica DH71 first lifted off from Sywell’s grass runway, it was a sight not seen in Britain for 95 years. Big congratulations to all involved, especially to Ron and Ben for initiating it, and Steve’s perseverance and skill in finishing all the last details to such a high standard. Honourable mentions also to John Tempest for the re-design work and Ben Cox for inspecting it, this was truly a team effort. Sadly, Ron Souch is no longer with us to see the Racer fly. https://video.wixstatic.com/video/62c8d3_cf3ab2cf7a524a2d953fd5a8f08ed411/480p/mp4/file.mp4 Steve describes his aircraft experience as starting as an aircraft engineering apprentice at CSE Kidlington, in the late 1970s. He towed gliders at Husbands Bosworth, in Chipmunks, at age 19, and joined the Tiger Club in the late 1970s, becoming a flying instructor at Staverton 1981. As he describes it, he somehow (?) ended up flying BA 747s for 20 plus years. His remarkable flying career has involved air racing, aerobatic competition and display flying, Redbull competitions and record setting in the Rolls Royce electric powered ‘Spirit of Innovation’ aircraft.

< Back New LAA Inspector - Neil Oakman 22 Sept 2025 We are pleased to welcome Neil Oakman as a new LAA Inspector, having attended an LAA Inspector Assessment Day at Turweston recently. Neil’s interest in aviation began during his early years living near the former RAF Sawbridgeworth airfield. Each summer, he would cycle to the edge of the old perimeter track to watch Piper Pawnee crop-spraying aircraft take off and land, sparking a lifelong enthusiasm for flight. After leaving school, Neil studied engineering and began working at local airfields, gaining hands-on experience with a variety of vintage aircraft ranging from Piper Cubs to the Sea Hurricane. This provided a strong foundation in both traditional aircraft construction and maintenance practices. He later pursued a career as a commercial pilot. Further details of his flying background can be found on his coaching profile on the LAA website. Throughout his aviation career, Neil has maintained his own aircraft as well as those of colleagues. This has given him a broad practical knowledge of types such as the De Havilland Chipmunk and the Scottish Aviation Bulldog, along with experience in maintaining aircraft constructed from metal, wood, and fabric. While his exposure to carbon and composite structures is limited at present, he is keen to expand his skills in this area as it represents a growing sector within the sport aviation community. As an LAA Inspector, Neil is committed to supporting aircraft owners by providing practical advice and guidance to help ensure their aircraft are operated and maintained to the high standards of safety, airworthiness, and reliability required by the LAA.

< 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 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-01-2025 ISSUE 2 published - Zenair Tailplane Brackets 28 Aug 2025 MTD-01-2025 - 'Inspection of horizontal stabiliser (tailplane) attachment brackets and associated hardware for cracks, looseness and other forms of distress' for Zenair CH601, CH650, CH701, CH750 and variants of these four models has been upissued to Issue 2. This is in order to correct an error in the 'Effective Date' of this MTD. This MTD can be found HERE and is also available below. A number of cases have been found whereby the structural integrity of the horizontal stabiliser mountings on the Zenair types identified above have been compromised by one or more of the following: cracking of the attachment brackets oversize holes loose rivets distorted and chafed brackets. These problems could occur due to a number of factors including poor build quality, a build-up of tolerances in the positioning or dimensions of the brackets, improper assembly, rough treatment or in-flight vibration. Failure of a tailplane attachment could result in degraded controllability in flight or loss of control. Special inspections of this area have been recommended by Zenair since January 2017, in their document ‘Mandatory Action. Jan. 2017 – Inspection of Horizontal Stabilizer tail attachment brackets’. This Mandatory Technical Directive mandates this safety action for aircraft operating on LAA Permits to Fly. 20250828 - MTD-01-2025 - Zenair Tailplane Brackets - Issue 2 .pdf Download PDF • 183KB Next Previous
