< Back MTD-02-2026 Issue 1 Published - Cracking in E-Props Durandal HexMc® Propeller Hubs 26 Jun 2026 MTD-02-2026 - Cracking in E-Props Durandal HexMc® Propeller Hubs This MTD is applicable to all aircraft operating under an LAA Permit to Fly fitted with an E-Props Durandal 3-blade propeller hub. A safety concern has been identified with certain HexMc® hubs where cracks may develop near the blade bolt areas, likely linked to over-tightening and possible manufacturing issues in specific production batches. Any HexMc® hub found to be cracked must be replaced with a serviceable, uncracked hub or the propeller replaced with an alternative propeller approved for that aircraft. Replacement hubs may be available from E-Props. Owners of cracked hubs are advised to contact E-Props directly before purchasing replacements. Within 10 flying hours or by the next Airworthiness Review, whichever is sooner, it must be determined whether the propeller hub is of an affected type and an initial inspection carried out by an LAA Inspector. If affected, ongoing inspections are required annually or every 50 flight hours. Please refer to the below Mandatory Technical Directive for full details, compliance times, and certification requirements. This MTD can be found HERE and is also available below. 20260625 - MTD-02-2026 Cracking in E-Props Propeller Hubs .pdf Download PDF • 459KB Next Previous

< Back MTD-04-2025 published Rans Control Linkage Rod End Connector Washers 13 Nov 2025 MTD-04-2025 - Replacement of all plastic control linkage rod end connector washers with metal washers During an inspection of an early Rans S6, all plastic washers between the bolt and bearing of the flap and aileron control linkage rod end connectors were found to be split or missing. This issue is identified in Rans’ service bulletin 012390-03. As plastic washers are susceptible to failure due to wear and embrittlement, this MTD is raised to mandate the replacement of all plastic control linkage rod end connector washers with metal washers. These washers prevent the rod end from disconnecting in the event of bearing failure. The washers fitted must be larger than the diameter of the bearing. Refer to here for a diagram. MTD-04-2025 can be found here and is found below. Note: Do not re-use nyloc or other self-locking nuts if their locking ability has become compromised.

< Back LAA Alert A-14-2025 - Eurofox Fuel Line Disconnected In-Flight 11 Dec 2025 LAA Alert A-14-2025 - Eurofox Fuel Line Disconnected In-Flight A non-LAA, Factory-Built Eurofox with a Rotax 915, fuel-injected engine experienced an in-flight engine shut down due to the high pressure (4.5 Bar) fuel hose connecting the high-pressure fuel pump unit to the master fuel valve becoming detached from the master fuel valve during flight. This resulted in the engine stopping and a serious fuel leak in the cockpit. It is believed that a combination of the fitting’s shallow barbs, and a small fuel leak of high-pressure fuel through the scratched/cut hose lubricated the fitting’s brass surface and allowed the hose to slide off the fitting. Owners and Inspectors should pay close attention to fuel hose condition and attachment security during inspections. Any signs of movement, wear, or mismatch between hose and fitting must be addressed before the aircraft flies again. Please refer to the attached Alert here for full details and recommended checks.

Over the years this has led to several commercially successful kitplanes (Europa, Streak Shadow, Sherwood Ranger), as well as designs that have been released for plans-building (Flitzer, Isaacs Fury, FRED) and a whole range of fascinating on-off personal aircraft – the Acro Advanced, Bonsall Mustang, Mickleburgh Sparrow to name just a few. There will always be LAA’ers keen on the ‘retro’ look, but with ever-increasing fuel costs we foresee a greater emphasis in future on aircraft exploring higher efficiency, alternative powerplants (electric?) and renewable materials. High hangarage fees mean that aircraft enthusiasts are more than ever interested in folding or de-riggable aircraft that can be kept at home. Using the information provided by clicking the links below, the LAA hopes to stimulate interest in light aircraft design, help potential designers through the process and encourage the development of high quality designs. With the decline in UK manufacturing over the recent decades, it seems more than ever important to keep alive a thread of creativity and enthusiasm for design and development. For some, the ability to bring a personal design from first concept to a flying prototype provides the ultimate source of satisfaction within the LAA scene. Designing Aircraft Since its formation in 1948, one of the stated aims of the LAA has been to encourage the designing and building of new types of light aircraft. For our own purposes, we in LAA Engineering have been producing a series of Excel spreadsheets to use as tools in the verification of calculations in the many aircraft design submissions we deal with. The spreadsheets have been designed to carry out the various calculations that are necessary during the design of light aircraft. Some of them have been written against specific paragraphs in the design code CS-VLA, whereas others, for example, cover areas related to the development of aircraft undergoing flight testing. In addition, simple spreadsheets for straightforward mathematical calculations have been written. It is for information and educational purposes that these spreadsheets are now available to LAA members on the LAA web site. Use the buttons below for more information on each design stage: Preliminary Design Detail Design Certification/Approval

Pilot Coaching Scheme LAA DTO The LAA is a CAA Declared Training Organisation (DTO). Our enjoyment of flying, and the ability to share that with others, carries with it a responsibility to maintain good standards of flying and airmanship. The Pilot Coaching Scheme (PCS) provides coaches to assist with specific courses and any general training need. COACHES The LAA has the Pilot Coaching Scheme - all Coaches are current CAA and Part 21-FCL certified Class Rating Instructors, Flight Instructors, or Flight Examiners. They’re also your trainer, confidante and mentor throughout the process of you learning to fly your aircraft. FIND A COACH Click on the button below to go to a map of all the LAA Coaches. You can find out their location, contact details, photograph and a short profile about them. Most coaches are happy to travel reasonable distances to accommodate your needs. WHY HAVE THE PCS? Statistics show that for LAA aircraft, the transition of a pilot onto a new aircraft type is a frequent source of accidents, more so than the aircraft's initial test flying phase. The same is true of the first flight of any unfamiliar aircraft, whether it is a home-built, vintage, or microlight. HOW IT WORKS Most LAA coaches have completed all differences themselves applicable to LAA types, so they can provide your differences or familiarisation training - though naturally, before doing so, they may need the opportunity to fly the aircraft sufficiently to acquaint themselves with the individual model concerned. WHAT DOES THE PCS OFFER? The PCS offers Licence Revalidation & Renewals, Differences Training, Familiarisation Training, Type Conversions, Licence Migrations and much more! Click the button below to find out what each of these means in detail.

< Back MTD-06-2025 published - Europa Tailplane Torque Tube Mod Failure 16 Dec 2025 Ref: LAA Mandatory Technical Directive MTD-06-2025 – Europa Tailplane Torque Tube Clamp Mod A recent inspection of a Europa fitted with the tailplane torque tube clamp modification, LAA MOD 10623, revealed both halves of the clamp had broken and fallen apart. These clamps are intended to prevent relative movement between the tailplane torque tube, the tailplane drive plates and the central drive horn, on which the mass balance arm is mounted. Failure of these clamps could allow free play to develop, potentially leading to taper pin hole damage, tailplane flutter, or jamming of the pitch control mechanism. An inspection must be carried out within the next 5 flying hours to determine whether MOD 10623 is fitted. If MOD 10623 clamps are fitted, making use of a light source and mirror as necessary, inspect the alloy clamp blocks for any signs of cracking (in particular along the sharp corner between the bolt flanges and main body), for any signs of looseness or relative movement between the parts and for any other abnormalities. If any of these are detected, the aircraft must not be flown and LAA Engineering must be contacted. This must be repeated at intervals not exceeding 25 flight-hours or the next Permit revalidation inspection, whichever occurs first, for as long as MOD 10623 remains fitted. Please refer to the below Mandatory Technical Directive for full details, compliance times, and certification requirements. This MTD can be found HERE and is also available below.
