Jabiru Engine Course Price Member - £213, Non-Member - £233 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. Your Instructor Clive James Dates TBC Times Arrival 09:00.

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.

Continuing Airworthiness Information One of the key strengths of the LAA's system is that we can monitor the fleet centrally and keep track of airworthiness incidents from around the world. Where necessary, we can then let our owners know, to help them keep flying safely.
