< 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 With the advice in JSB-012 (Issue 9 onward) having been promulgated by Jabiru, LAA has withdrawn Alert AWA/20/15, which means that provided the advice in JSB-012 Issue 9 or subsequent is followed, along with regular bolt torque checks at every 100 hours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 Eurofox Rudder Pedal Failures - LAA Standard Modification Approved & MTD-05-2025 Issue 4 19 Jan 2026 LAA Standard Modification SM16826 provides a terminating action to the 10-hour inspections required in LAA MTD-05-2025, which has now been up-issued to ISSUE 4 The LAA Standard Modification – SM16826 ‘ Reinforcement of Rudder Pedal to Torque Tube Joints ’ has been through our internal review process and is now formally approved. SM16826 strengthens all 4 pedal joints by the addition of welded steel, wrap-around finger plates. Incorporating this standard modification provides a terminating action to the 10-hour inspections required in LAA MTD-05-2025, which has now been up-issued to Issue 4. The CAA have also confirmed that incorporating this modification will be a terminating action for CAA MPD-2026-002-E and we expect the MPD to be upissued this week to reflect this. Once Standard Modification SM16826 is completed, owners will need to submit an LAA/MOD 1 Form ( Standard Mod Incorporation ) to let us know that the modification has been embodied, so that we can update our records at LAA HQ. A copy of Form LAA/MOD 1 is here . As a CAA-approved welder is required for this modification, owners have been provided with a list of CAA welders known to the LAA.

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.
