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), an LAA Inspector can sign off the change. Technical Leaflet TL 3.29 N/A N/A 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.

< Back Alert A-04-2025 - Jabiru Flywheel Bolts 12 Jun 2025 LAA Alert A-04-2025 - Jabiru Flywheel Bolts LAA Alert A-04-2025 has been published on the LAA website (and is also attached), highlighting the Installation Procedure, Torque Checks and Replacement Interval for Flywheel Attachment Bolts on aircraft equipped with Jabiru 2200, 3300 and 5100 engines, and withdrawal of LAA Alert AWA/20/15. With the advice in JSB-012 (Issue 9 onward) having been promulgated by Jabiru, LAA has withdrawn Alert AWA/20/15, which means that provided the advice in JSB-012 Issue 9 or subsequent is followed, along with regular bolt torque checks at every 100 hours and annual check as called for in the Engine Maintenance Manual, the recommended bolt life is as stated in the Engine Maintenance Manual (currently 500 hrs). For LAA aircraft having the flywheel bolts replaced, or torque checked, the work must be overseen and signed-for by a suitably approved LAA Inspector. Engine logbook entries must be made and certified with a PMR statement referencing JSB-012 in the logbook white pages, as well as an entry in the logbook pink pages (or equivalent method for tracking continued airworthiness compliance).

< Back New Permit Revalidation System Announcement 20 Mar 2025 The new Permit Revalidation System is coming on 15th April - watch the announcement video below to find out more! https://www.youtube.com/watch?v=qO-XPiiNxjg 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

Lycoming Lycoming engines in certain specific airframe types have been approved by the CAA for the use of unleaded Mogas, using the process described in CAP747 , See Section 2, Part 4, General Concession 5. This involves purchasing an STC (Supplemental Type Certificate) from either the EAA or Petersen Aviation in the USA and carrying out the actions called for by the STC. The procedures stated in CAP747 may be followed for LAA aircraft but only for aircraft with the exact same engine/airframe combinations quoted on in CAP747.. An LAA inspector must check that the aircraft operator has obtained a copy of CAP747, Section 2, Part 4, GC5 and of the appropriate STC and complied with the actions called for therein, and signed off a suitable logbook entry accordingly before the aircraft may be flown with unleaded Mogas.

Rotax Fuel Injected 912 iS / 915 iS Installation & Operation Price Member - £224, Non-Member - £244 Duration Arrival 09:30. Finish 17:00. < Back About the Course With the growth of interest in the fuel-injected Rotax 912 and 915 iS series engines, it has become apparent that there is a lot of confusion and misunderstanding about the installation and operation of these engines and the way that the latest built-in systems work. Electronics and Rotax iRMT certified engineer, John Barrott, was an early installer of a 912iS and found it difficult to find accurate information on best practice. Working with UK Rotax agents CFS and LAA Engineering, John has built up a comprehensive understanding of the iS engines and has developed a course around this to provide help and advice on the installation and operation of this new generation of aero engines. The course is classroom (not workshop) based. Your Instructor John Barrott Dates Saturday 21 February 2026 Times Arrival 09:30. Finish 17:00.
