Modification & Repair Worklist Below is a list of modification and repair applications that are awaiting review by our engineers. Un-allocated applications are reviewed weekly and those approaching the top of the list will be allocated to an engineer - this helps to balance individual engineer's workloads more evenly. 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. Our apologies for the current length of the work queue which has been due to staff absences combined with a high number of new and returning applications. We're working hard to get through the projects and are looking to put additional resource into clearing the backlog. Thanks for your patience.

< Back Alert 05-2024 - Rotax Oil Spray Nozzles - upissued to Issue 2 24 Jul 2025 LAA Alert 05-2024 - Inspection and/or Replacement of Oil Spray Nozzle in some Rotax 900 series engines - upissued to Issue 2 On 16.12.24, Rotax issued a MANDATORY Service Bulletins SB 912 i-016/SB 915 i-016 / SB 916 i-006 and SB-912 i-016iS / SB-915 i-016iS / SB-916 i-006iS which call 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. Therefore, LAA Alert A-05-2024 was issued on 17th December 2024 regarding this. Subsequently, a revision to the Rotax Service Bulletins was issued on 20.12.24, entitled MANDATORY Alert Service Bulletins ASB 912 i-016 R1/ASB 915 i-016 R1 / ASB 916 i-006 R1 and ASB-912 i-016iS R1 / ASB-915 i-016iS R1 and ASB-916 i 006iS R1. Therefore, on 23rd July 2025, LAA Alert A-05-2024 was upissued to Issue 2, which now supersedes Issue 1. A-05-2024 Issue 2 can be found HERE and is also found below. 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.

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 3.06 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.
