< Back Alert A-11-2025 - Eurostar aileron rose joint and rudder hinge inspection 8 Oct 2025 LAA Engineering has issued Alert A-11-2025 to highlight the recent issue of an Airmasters service bulletin that requires checks on the integrity of a rose joint in the aileron controls and the rudder hinge, following examples of these joints migrating and jamming aileron controls. Following the up-issue of Airmasters SB/EUR/023 to issue 3, on 07/10/25 CAA has issued MPD 2025-004-E to mandate the checks contained in the SB, which supersedes MPD 2025-003-E initially issued on the subject.

< Back LAA Alert for some models of Rotax Engines 1 Mar 2025 LAA Alert A-02-2025 has been published on the LAA website (and is also attached), highlighting a recent service bulletin published by Rotax regarding the inspection and/or replacement of the crankcase and/or gearbox housing on affected engines. Rotax has identified a potential manufacturing issue affecting the hardness values of the crankcase and/or gearbox housing materials in certain engines. These components may not meet the required specifications for material hardness, which could lead to reduced component durability and/or potential oil leakage. Rotax regards this bulletin as mandatory. A-02-2025 - Rotax Crankcase .pdf Download PDF • 220KB Next Previous

< 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 New LAA Inspector - Conrad Ceillam 2 Sept 2025 We are pleased to welcome Conrad Ceillam as a new LAA Inspector, having attended an LAA Inspector Assessment Day at Turweston recently. As a youngster, he worked mostly on 3-engined piston aircraft for commercial flight, and on some twin turboprops in Guernsey. He then moved on to mostly narrow-bodied jets and turboprops, with some executive jets in the UK. Latterly, he worked in Finland on medium-bodied jets, scientific aircraft, and mission/patrol. Since moving to Shetland, he has mostly worked on twin-piston passenger craft. He has held BMAA inspector approvals since April 2023. Next Previous

Permit Aircraft Electrics - Basic Course Price Member - £224, Non-Member - £244 (includes printed course material) Duration Arrival 09:00. Finish 17:00. < Back About the Course This course provides the theory and practical knowledge to enable the implementation of a basic electrical system in permit aircraft. Although the course necessarily includes a small amount of technical theory; it is only included at a level needed (essentially Ohms Law) to understand how wire sizes, fuses, circuit breakers and other components etc are selected. The basic premise of the introductory course is that the owner/builder already has a circuit diagram to work from (few kit manufacturers provide electrical diagrams, so the course includes details of where such ‘standard’ diagrams may be found). They are not expected to do any design work, but they do need to source the materials and components and build a working, reliable and safe installation. The course explains how to interpret a ‘typical’ permit aircraft electrical systems diagram and for every element, explains how to size, select and source components and then how to practically install them. The course uses a PowerPoint presentation for the theory side, a demonstration electrical panel in the classroom so that attendees can see the various options and good practice for wiring and systems installation and also runs two practical sessions in the LAA workshop which includes practical soldering, wire stripping and connector crimping, cable marking options, use of heat shrink, radio antenna coax connector installation and the correct crimping and installation of typical D Sub connectors used for avionics systems. What this course will try to do is: Introduce and explain the components of a wiring system Help you understand a circuit diagram Give practical experience in wiring techniques Give the knowledge to select and source cables and components Explain failure modes and reliability issues Help you conduct basic fault finding Warn about the ‘gotcha’ areas and the things to look out for What the course will not do is: Turn you into a design engineer Enable you to design an aircraft EWIS Enable you to fault find on an undocumented aircraft installation Solve interference issues Delve into avionics Your Instructor Mark Castle-Smith Dates Date tbc Times Arrival 09:00.

Preliminary Design Preliminary Design is the stage where the design is sized and developed in outline, leading to a three view drawing, performance and weight predictions. To help with this, LAA has developed a number of spreadsheets. Spreadsheet 1 is used to develop the basic geometry of the proposed aircraft, size the wing, fuselage and tail surfaces and work out some of the key parameters used later. Spreadsheet 2 is used to estimate the performance of the aircraft based on the geometry, initial weight estimates, engine power and guestimates of the drag coefficient and prop efficiency, allowing you to see how the performance is affected by changing each parameter in turn. Spreadsheet 3 is used to work out the critical structural speeds, develop the flight envelope and predict the aerodynamic loads on the main surfaces which can be used to size the structure, and as the basis for a load test program. The weight and balance spreadsheet elsewhere on our website allows the designer to quickly evaluate the implications on weight and cg of different positions for the crew, fuel tanks and baggage bay, and work out what empty aircraft weight and cg he must aim for. Thanks to the simplicity of these programs it takes only minutes to study the implications of changing the aircraft’s specification, for example the effect of changing the wing aspect-ratio, the trade-off between extra weight and cleaning up the airframe drag, extra power etc. Downloadable Spreadsheets Worked Spreadsheet Examples Design Tutorials

< Back New LAA Inspector - Stuart Porter 15 Nov 2024 The LAA is pleased to welcome Stuart Porter as a new LAA Inspector. Stuart attended an Assessment Day at LAA HQ in September.
