Modification & Repair Worklist Below is a list of modification and repair applications that are awaiting review by our engineers. Un-allocated applications are reviewed weekly and those approaching the top of the list will be allocated to an engineer - this helps to balance individual engineer's workloads more evenly. 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. Our apologies for the current length of the work queue which has been due to staff absences combined with a high number of new and returning applications. We're working hard to get through the projects and are looking to put additional resource into clearing the backlog. Thanks for your patience.

Armstrong/Isaacs Bursary 2027 Bursary applications now open! Deadline : end of February 2027 Five bursaries of up to £1,500 are offered every year to support young pilots already in PPL training. To qualify for these bursaries you must be under 30, are required to already have reached ‘first solo’ standard, have completed a minimum of five hours solo training and have gained the necessary medical and ground qualifications to continue your training. Application form can be found here Armstrong/Isaacs bursaries are funded from the Armstrong/Isaacs Fund, which is based on a major donation from David Armstrong, who was a founder member of the original ULAA in 1947, a lifelong member of the LAA’s predecessor the PFA and the latter’s chairman from 1960 to 1964. His legacy, co-named with that of aircraft designer and builder John Isaacs, has, since 1998 enabled many young prospective pilots to gain their PPL. And of course, from kind donations from our members.

Weight & Balance The subject of Weight and Balance covers at least four distinct procedures: weighing an aircraft, calculating its empty weight and centre of gravity (CG), establishing the worst forward and aft CG loading cases according to an appropriate design code and calculating weights and centres of gravity for an actual flight. This section includes guidance notes on each of these aspects, forms and worked examples (imperial or metric) for recording and calculating empty weight and CG, as well as worst forward and aft CG cases and an Excel based spreadsheet that makes the weight and CG calculations for you. The table on the spreadsheet is set out in the same layout as the Loading Examples tables. This spreadsheet can, of course, also be used for carrying out calculations for an actual flight. Simply input the actual weights of the items to be loaded rather than the standard occupant or maximum fuel and baggage weights. Remember, it is important to check that the CG remains within limits with no usable fuel as well as with the loaded fuel in the tanks, even though it will not be your intention of running the tank dry. The calculator generates two sets of weight and CG values for this purpose. Weight & Balance arrangements for gyroplanes are different to those of aeroplanes and a special type of report is used, unless the manufacturers concerned provides their own special schedule in which case this should be used instead. Before accessing the documents below, please ensure you have read Technical Leaflet 3.16 - Weight and Balance Guidance Notes .

< Back MTD-07-2026 - Vans Horizontal Stabiliser Attach Position - Issue 2 25 Aug 2026 MTD-07-2026 Issue 2 Horizontal Stabiliser Forward Attach Bolt Position - Van’s SB 00134 Revision-1 MTD-07-2026 has been upissued to Issue 2 in order to align with the re-issue of Vans SB 00134 at Revision 1 on 22.8.26. This revision of the SB, and MTD-07-2026 Issue 2, allow a slightly further reduced spanwise edge margin on the outboard bolt holes to the ends of F-710B, providing the outboard bolt hole falls entirely within the width of the longeron’s flange. MTD-07-2026 also provides additional guidance in the notes section about how to carry out the measurements without removing the bolts. The inspection is to be carried out in accordance with Van’s SB 00134 Revision 1, with the results recorded on the Appendix A table of MTD-07-2026 Issue 2. As this MTD is mandatory for applicable Van’s RV aircraft operating on an LAA Permit to Fly, the required inspection must be completed within the next 10 flying hours or 90 days from the effective date of the MTD, whichever occurs first. If all bolt-hole positions are within the acceptable limits, compliance can be certified and recorded in the aircraft logbook. If any bolt-hole position falls outside the permitted limits, the aircraft must not be flown and the results must be referred to Van’s Aircraft and LAA Engineering for further advice. For aircraft which have already been checked and found satisfactory in accordance with MTD-07-2026 Issue 1, no further action is required. Please refer to the MTD below for full applicability and compliance requirements. 20260825 - MTD-07-2026 - Vans Horizontal Stabiliser Attach Position Iss 2 .pdf Download PDF • 476KB SB 00134 - Horizontal Stabilizer Forward Attach Bolts - Rev 1 .pdf Download PDF • 1.57MB Next Previous
