< 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.

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 7 February 2026 Times Arrival 09:00.

< 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

Jabiru Engine Course Price Member - £206, Non-Member - £226 Duration Arrival 09:00. Finish 17:00. < Back About the Course It is widely accepted that a good working knowledge of an engine will help a pilot to service and maintain it to a satisfactory standard. This course is designed to give pilots sufficient knowledge to be confident that their engines are both serviceable and airworthy and; if an issue is detected, to know whether they have the ability to resolve the issue or need to seek assistance. The course will also cover the common engine weaknesses and the important Jabiru modifications. The course primarily focuses on the 4 and 6 cylinder generation 1-3 engines. The course will also benefit owners of the latest generation 4 engine, but information will be limited due to the overall hours flown to date for this type of engine. The Aim of the Course The aim of the course is to give Jabiru engine operators sufficient knowledge to maintain and operate their engines. Method A classroom slide presentation will be given , supported by a demonstration engine and parts, detailing the build of a Jabiru engine from the crankshaft up. The slide presentation will also use the knowledge gained from the virtual build and cover how to check for engine serviceability prior to flight. Course Instructor: Clive James. Clive has owned and operated a Jabiru for over 20 years and in that time has worked on many engines, including 4 and 6 cylinder engines. Clive also provides technical assistance to many Jabiru engine owners, helping them maintain their engines to an airworthy standard.
