< Back Alert A-08-2025 - Gen 4 Jabiru 3300 Engine Crankshafts 25 Jul 2025 LAA Alert A-08-2025 - Gen 4 Jabiru 3300 Engine Crankshafts On 11.4.25, Jabiru Aircraft Pty Ltd issued a new Service Bulletin, JSB 046, which applies to specific Jabiru 3300 engines and requires the replacement of the crankshafts on engines within certain serial number ranges, which they state were supplied between April 2017 and June 2024. Jabiru regards the Bulletin as mandatory. The Bulletin advises that Jabiru has identified that, as a result of an issue with heat treatment, crankshafts supplied with the affected engines are in some cases susceptible to failure. Jabiru have specified that the crankshaft must be replaced by a crankshaft of the later, improved design. Affected crankshafts must be replaced prior to 15th December 2026, or 150 hours total time in service (TTIS), whichever occurs later. A-08-2024 can be found HERE and is also shown below.

< Back LAA Alert A-13-2025 - CZAW SportCruiser Nose-Leg Failures 10 Dec 2025 LAA Alert A-13-2025 - CZAW SportCruiser Nose-Leg Failures LAA Engineering has issued Alert A-13-2025 to highlight the recent issues of SportCruiser Nose-Leg Failures. Two SportCruisers have recently suffered nose landing gear collapses, resulting in propeller strikes and airframe damage. Inspections have revealed evidence of cracking and possible weld-related weakness. Owners and Inspectors should carry out frequent checks for cracks, corrosion, and deformation on the nose-leg, paying particular attention to weld points. If any abnormalities are detected, the aircraft must not be flown and LAA Engineering contacted. Please refer to the Alert here for full details and recommended checks.

< Back MTD-05-2024 - Jabiru Distributor Caps - Issue 2 23 Jul 2025 MTD-05-2024 - Jabiru Distributor Caps - has been upissued to Issue 2 today. This MTD can be found HERE and is also available below. On 10th July 2024, LAA Engineering published Issue 1 of MTD-05-2024. This was published due to apparent variations in the design of the distributor caps and rotor arms on Jabiru 2200 engines, which meant that, in some cases, there was insufficient clearance between the rotor arm and centre boss of the distributor cap, causing the contact button of the distributor cap to be flattened against its range of travel by the rotor arm, which causes extremely accelerated wear leading to ignition issues and potential engine failures. Today, Issue 2 of MTD-05-2024 has been issued, superseding Issue 1. Issue 1 of MTD-05-2024 detailed a method for ensuring sufficient clearance between the centre boss of the distributor cap and the rotor arm. This method has now been superseded by Jabiru’s Service Bulletin JSL050. LAA MTD-05-2024 Jabiru distributor cap Iss 2 .pdf Download PDF • 294KB Next Previous

< Back LAA Alert issued for Lycoming Engines 28 Nov 2024 The LAA has issued Alert A-02-2024 (link below) to highlight the recent Lycoming Airworthiness Directive regarding connecting rod bushings and connecting rod assemblies. The FAA has issued a new airworthiness directive (AD) for models of Lycoming engines that have an affected part installed and are assembled within the ship date range, as specified in Table 1 to paragraph (c) of this Airworthiness Directive (AD 2024-21-02). The AD comes into effect on 5th December 2024. This AD was prompted by several reports of connecting rod failures which resulted in uncontained engine failure and in-flight shutdowns. The AD requires repetitive oil inspections for bronze metal particulates at each oil change, and if found, additional inspections of the connecting rod bushings for damage, proper fit, movement, and wear, and replacement if necessary. The first oil inspection must take at the next oil change or within 4 months after the AD becomes effective i.e. 5th April 2025, whichever occurs first. As terminating action to the connecting rod bushing inspections, this AD requires replacement of the connecting rod bushings with parts eligible for installation.

< Back Mandatory Technical Directive issued for Rotax 914 powered Eurofox aircraft 29 May 2024 Mandatory Technical Directive, MTD-03-2024 has been issued today to introduce mandatory disabling of cabin heat on examples of the type fitted with Rotax 914 (and derivative) engines. This follows an in-service occurrence of carbon monoxide entering the cabin due to leaks from the exhaust system. The MTD must be carried out before flight on or after 5th June 2024. This MTD has been emailed to all affected owners. Next Previous

< Back The New Permit Revalidation System 28 Feb 2025 As the weather improves and the days grow longer, the flying season is just around the corner. Although you may already be thinking about all your usual flying preparations, there is one extra exciting update Owners and Inspectors alike should keep in mind this year: the launch of the new Permit Revalidation System. A flow chart of the new Permit Revalidation Process This new system will be fully online, and submission of your revalidation application will be via the LAA website under the “My Aircraft Details” section. Therefore, before arranging for an inspection this year, please make sure you can access your LAA member page. You can do this by going on www.lightaircraftassociation.co.uk and clicking on the Login button at the top left of the page and checking that your aircraft details are correct. If you have any issues with your login or aircraft details, please contact the LAA Office on 01280 846 786 or via email at [email protected] Screenshot showing where to login on the LAA website Screenshot showing the ‘My Aircraft Details’ button once you have logged into the LAA website Screenshot showing the button to start apply of your Permit to Fly Revalidation in the ‘My Aircraft Data’ area Applying for revalidation under the new system will be straightforward. Aircraft owners will begin the process by selecting their Inspector. Once selected, the Inspector will be notified that an application is awaiting their attention. After the Inspector submits their airworthiness review, the Owner will be prompted to pay for the revalidation, at which point the application will be sent instantly to LAA Engineering for issue. We are also planning to reduce the requirement for a check flight from one to three years for most aircraft types. However, Inspectors will also have the flexibility to request a check flight as part of the revalidation, if deemed necessary. Additionally, once the new system has launched, Inspectors will be able to issue PFRCs up to two years past the expiry of the Certificate of Validity. Please note, these changes, along with the new check flight cycle, will take effect only once the new system is officially launched. As we get closer to launch in April, more guidance, including a video and notes, will be shared with Owners and Inspectors, ensuring a smooth transition to the new Permit Revalidation System. Stay tuned for more! Next Previous

< Back Mandatory Technical Directive issued for Supermarine Spitfire mk26 and mk26a 16 Feb 2024 It has been found that there is potential for the fin of the Supermarine Spitfire Mk26 and 26B to be misaligned during build, due to a build-up of tolerances in the fin and its attachment, possibly leading to a mis-rigging of the rudder and failure to achieve the desired range of rudder travel. This could possibly result in degraded controllability in flight and on take-off and landing. In the interests of safety MTD 01-2024 calls for mandatory checks to be made on the fin alignment and rudder range of movement. Next Previous
