Modification & Repair Worklist Below is a list of modification and repair applications that are awaiting review by our engineers. 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.

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 Saturday 5 December 2026 Times Arrival 09:00.

Permit Aircraft Electrics - Advanced Course Price Member - £224, Non-Member - £244 (includes printed course material) Duration Arrival 09:00. Finish 17:00. < Back About the Course The Basics course covers simple DC theory and concentrates on the practical aspects of installing a basic permit aircraft electrical system. 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. This Advanced course builds on the Basics course by providing more detail about component selection and options and the use of integrated power management systems within permit aircraft. The course takes the simple systems design introduced in the Basics course and explores options for creating more complex electrical systems including the use of dual and essential system bus bars. The course introduces fault tolerant design considerations, thus allowing attendees to consider safety and fault analysis in their own designs. As a tool for understanding this aspect of the course, it will take an introductory look into the requirements of electrical systems for those wishing to fly their aircraft under IFR. What this course will try to do is: Explain power generation and distribution options in a light aircraft More advanced consisderations into component selection Discuss circuit protection devices and systems Explain failure modes and reliability issues Introduce interference and EMC issues Show correct grounding and screening techniques Provide you with the knowledge to plan an installation and create the necessary documentation Warn about the ‘gotcha’ areas and the things to look out for What the course will not do is: Turn you overnight into an expert Enable you to fault find on an undocumented aircraft installation Delve inside avionics boxes It will be useful, but not essential, for people to have previously attended the Basic course. In order to make the best of this course, if you have not attended the basics course, you will need to understand basic DC theory; Ohms Law and the Power Law. Please note that this course is primarily a classroom based course, as you will already have the practical skills you need, which are covered in the basics course.

An Introduction to Aircraft Flying Qualities Price £500 for members, £550 for non-members Duration 09h00 to 17h00 both days < Back About the Course All aircraft need good flying qualities to enable safe flight. Flying qualities – the response of an aircraft to the pilots control inputs - are influenced by key design characteristics of the aircraft including the wings, fuselage, empennage, mass and balance, control systems, propulsion systems, or high lift devices and landing gear where fitted. This course describes how the design (and construction) of a fixed wing light aircraft may positively or negatively impact flying qualities. The course begins with a description of the underlying theory of stability & control, design guidelines and relevant certification standards for a light aircraft. Examples and accident case studies are used to support the theory. Test methods used to assess flying qualities are described and practical ‘hands on ‘ exercises are performed using a fully immersive Virtual Reality + Motion simulator to experience the effects of design changes on flying qualities. This ‘hands-on’ course is conducted over two full days with day one covering longitudinal stability and stalls with day two covering lateral/directional stability and spins. The course finishes with a summary of the theory and exercises conducted plus recommended references for further study. Course tutor is Dr Mike Bromfield. Mike is an Aerospace Systems & Human Factors Engineer with Myriad Business Ltd. He is also an Associate Professor (Honorary) in Aerospace and Flight Safety Researcher at the University of Birmingham and a Chartered Engineer and Chartered Ergonomics/Human Factors Specialist. He is a private pilot and a trained flight test engineer.

< Back Positive Progress 11 Sept 2026 Positive progress on the investigation into the tailplane attachment bolt hole positioning issue We wanted to provide a further update on the investigation into the tailplane attachment bolt hole positioning issue identified in some RV aircraft, and to share the encouraging progress that has been made. Since issuing MTD-07-2026 on 19th August and the revised Issue 2 on 25th August, which included a helpful relaxation of one of the edge-distance limits, we have received around twenty reports from owners whose aircraft were found to be outside the published criteria. Van's Aircraft has received more than sixty similar notifications following the release of Service Bulletin SB-00134. Many of these reports have provided valuable data, which is helping build a clearer understanding of the issue across the wider RV fleet. Over recent weeks, LAA Engineering and Van's Engineering Team have been working closely together, reviewing these reports on a daily basis. By examining the various types of edge-margin discrepancies in detail, we have been able to develop a much better understanding of the structural implications and the most appropriate solutions. Following a very productive meeting on 9th September with Van's Chief Engineer, Rian Johnson, LAA Engineering will now reassess all reported LAA cases in light of this latest technical work. We are optimistic that a number of aircraft may be able to return to flight immediately without further action. Others may require only limited rework, while a smaller number may need more extensive rectification. These reported cases are our highest priority, and we intend to provide individual responses to affected owners by 18 September 2026. Where a straightforward solution is not immediately available, we will look to Van’s for a proposal of how to deal with the individual aircraft. A particularly positive development is that Van's has completed additional finite element analysis of the affected structure and, based on these findings, has released Revision 2.1 of Service Bulletin SB-00134, dated 4th September. This latest revision introduces further relaxations to some of the bolt-position criteria, reflecting increased confidence in the structural capability of the design. In certain cases, aircraft previously considered non-compliant may now be acceptable for continued operation, subject to periodic inspections. We are currently awaiting some additional technical data relating to Service Bulletin revisions 2.0 and 2.1 before publishing MTD-07-2026 at Issue 3. Until the revised MTD is issued, owners carrying out MTD-07-2026 Issue 2 must continue to apply the criteria contained within SB-00134 Revision 1 and continue reporting any non-conformances to both the LAA and Van's. We are in the process of updating MTD-07-2026 to reflect the latest engineering findings from Van's and to incorporate any additional improvements that can simplify inspections and minimise disruption to owners. Our aim is to provide clear, practical guidance that supports both safety and continued flying activity wherever possible. If your aircraft is found to be non-conforming, we would be grateful if you could also include photographs of both bolt groups from above and below (using a mirror or endoscope where necessary). These images are proving extremely valuable in helping our engineers assess each case efficiently and determine whether any corrective action is required. We appreciate the patience and cooperation shown by RV owners throughout this process. The close collaboration between owners, the LAA and Van's has already produced significant progress, and we remain committed to restoring aircraft to service safely and as quickly as possible.
