We provide a system whereby members can build an aircraft in the comfort of their own home (or wherever they choose) from either a set of plans or from a kit of parts. Every year around 100 newly-constructed aircraft are added to the LAA fleet, with members generally taking around 1 to 4 years to complete their kit projects. A whole range of aircraft is available to build, from single-seaters to four-seaters, aerobatic to amphibian, and WWI replica triplanes to gyroplanes. The LAA is tasked with ensuring that the designs members build meet minimum airworthiness requirements, appropriate to the type. Proposals for accepting other designs of aircraft can be put to the LAA, and a number of such types are accepted each year following a review of their airworthiness, amongst other things. This requires a member to champion the type through the process, arranging for the necessary technical information to be passed to the Engineering department and to build and test the first example. Similarly, it is possible for a member to build an aircraft of their own design. LAA provides support for this (see the Designing aircraft section), but due to limited resources only the most promising/developed designs can be advanced through the system. Building Aircraft One of the founding principles of the LAA is to provide for members wishing to build their own aircraft, either for their own education or to enable them to own an affordable aircraft. Of course, whichever type you choose it is usually possible to customise it to your liking using the LAA’s modification system. So if it’s an elaborate avionics suite that takes your fancy or an automotive engine conversion, there’s a route to investigating whether it’s possible. If you like the idea of building, but feel you lack the skills, then there are courses on various aspects of aircraft building to help bring you up to speed. Your Inspector is also a fantastic mine of information and generally will be your first port of call for technical information. Of course, the LAA also has a pool of full-time engineers who can be contacted for advice.

< Back LAA Alert for Rotax 900 series engines regarding the oil spray nozzle 18 Dec 2024 Inspection and/or Replacement of Oil Spray Nozzle On 16.12.24, Rotax issued a new MANDATORY Service Bulletin SB 912 i-016/SB 915 i-016 / SB 916 i-006 which calls for urgent action for engines of specified models within certain serial number ranges, if the engine has run for less than 200 hours from new, or engines which have been fitted with specific overhaul kits supplied between 01.01.22 and 31.10.24 inclusive. The bulletin concerns problems with a possible full or partial blockage of the oil spray nozzle due to an excessive application of Loctite at the manufacturing stage, when assembling the sprag clutch housing. This can lead to inadequate cooling of the stator assembly, potentially causing loss of electrical power to the engine’s ECU.

Permit Aircraft Electrics - Basic Course Price Member - £216, Non-Member - £236 (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 New dates tbc Times Arrival 09:00.

< Back The New Permit Revalidation System - Step-by-Step Guide 9 Apr 2025 The new LAA Permit to Fly revalidation system will go live on 15th April 2025. This streamlined, fully online process offers an easier and faster way for aircraft Owners and Inspectors to handle Permit to Fly revalidations. Watch this video for a step-by-step guide on how to complete the online Permit Revalidation process, both as an Owner and as an Inspector. There are a few key considerations to ensure your revalidation under the new system goes smoothly: Please make sure you know your username and password before applying for your aircraft’s revalidation. 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 you submit the revalidation application. This is in order to provide a baseline for the online system. The 3-year check flight schedule will then apply subsequently to most aircraft types. Some aircraft will still require a check flight at every revalidation, these are: Aircraft cleared for glider tugging in their Operating Limitations document. Aircraft cleared for Night/IFR. Aircraft which have flown less than 12 hours since the previous revalidation inspection. You will not have to submit your CFS-1 Check Flight Schedule when applying through the new system. However, a CFS-1 will need to be completed for each check flight and stored with the aircraft’s documentation, so that it is available when needed. We encourage you submit your revalidation application through the new online system, as processing time is expected to be faster than an ‘old-style’ revalidation. If you still wish to make an ‘old-style’ application up until 15th May 2025, all 3 forms must be submitted by this date and you will only transition to the 3-year check flight schedule after your first revalidation through the new system. Note: The option to apply for revalidation in ‘My Aircraft Data’ on the LAA website may appear shortly before the go-live date on 15th April 2025 as our IT infrastructure is updated. However, we will only be able to process applications received on or after the official go-live date.

Modifying & Repairing Aircraft One of the main features of the LAA system is that modifications and repairs can be approved with significantly reduced costs compared with aircraft on Certificates of Airworthiness, where applicants would need to deal with the CAA or EASA. Since the engineering team are all ‘little aircraft’ experts, it is usually a straight-forward job to approve many types of change. Of course, with many of our members being so creative, sometimes the job takes a little more time and thought to approve! View current mod/repair application queue Modifcation Type Description Further Details Application Form Application Fee Category Changes Applications to change an aircraft’s category from a microlight to a ‘Group A’ aircraft (and vice versa) are allocated a modification number to record the change. If an engine or propeller change is required at the same time, then an application must be made as noted above. N/A LAA/ MOD 10 £206 Engine & Propeller Changes These are treated as Prototype or Repeat modifications, unless they appear on the PTL list for the type. Technical Leaflet TL 3.02 LAA/MOD 4 and LAA/MOD 5 * See below Avionics Installations These are not considered modifications, but in order to fulfil their legal obligations, owners are required to keep LAA up-to-date should radio details alter. A special system exists for the approval of radio changes that is separate from other modifications. Technical Leaflet TL 3.03 LAA/MOD 7 No charge for radio/transponder installations, but a £31 fee is chargeable for certified ADS-B Out applications STCs Where a change has previously been approved by means of a Supplemental Type Certificate (STC), LAA Engineering then only needs to investigate any installation/compatibility issues rather than the change itself. N/A LAA/MOD 13 £52 The Trivial Change Sometimes a change is so trivial that no application is required and there is no need to inform the Engineering department. Technical Leaflet TL 3.10 N/A N/A Manufacturers' Modifications Kit manufacturers and plans suppliers often have long lists of optional modifications that can be fitted and during the lifetime of a type product improvements are introduced. Generally, LAA-accepted optional items are listed on the TADS for the type. N/A N/A N/A The Standard Modification This is a modification that is very well defined and is applicable to a particular aircraft or engine type or types. Members may nominate new Standard Modifications using form LAA/MOD 9; however, LAA Engineering may choose to convert popular Repeat modifications into Standard Modifications. Technical Leaflet TL 3.06 LAA/MOD 1 Variable, see individual mods for details The Repeat Modification A modification that has already been approved on one aircraft as a Prototype modification. Note that a Repeat modification must identically replicate the original Prototype modification including fasteners and positions of parts and should generally be on the same aircraft type as the original. Technical Leaflet TL 3.07 and TL 3.17 LAA/MOD 11 * See below The Prototype ("normal") Modification This is a normal modification application made in the usual way and is applicable only to the aircraft for which the application is made. Technical Leaflet TL 3.01 LAA/MOD 2 and LAA/MOD3 * See below * All prototype modifications (including engine and propeller changes) attract a minimum fee of £103 which covers up to two hours' work; all repeat modifications (including engine and propeller changes) attract a minimum fee of £52 which covers up to one hour's work. Thereafter, work is charged at £57/hour in either case. See the relevant Technical Leaflet for the type of modification for further details.
