< Back Carbon Monoxide in Piston Engine Aircraft Consultation 22 Feb 2024 In recent years, the CAA has been actively engaged in raising pilot awareness of carbon monoxide (CO) in general aviation (GA) and has undertaken multiple initiatives to promote prevention and detection measures to mitigate the risk. We have now launched a public consultation seeking stakeholder views on: the barriers pilots face in obtaining an active CO detector, the role that maintenance plays in combatting CO, the importance of protecting passengers from CO, and whether active CO detectors ought to be mandatory for some operations. The consultation closes on 20 March 2024. We invite stakeholders to give us your views . Next Previous

< Back MTD-04-2025 upissued to Issue 2 - Rans Control Linkage Rod End Connector Safety Washers 18 Nov 2025 MTD-04-2025 Issue 2 - Rans Control Linkage Rod End Connector Safety Washers MTD-04-2025 Issue 1 was recently published to mandate the replacement of all plastic control linkage rod end connector washers with metal washers . It has become apparent that the washers specified in this MTD are not suitable to replace the plastic washers due to their dimensions. MTD-04-2025 Issue 2 has been raised in order to amend the specification of the metal washers that must used to replace plastic washers. Therefore, MTD-04-2025 Issue 2 supersedes Issue 1. Issue 1 of this MTD is now cancelled. Please refer to the attached MTD document for full details and compliance instructions, which can also be found on the LAA website HERE .

< Back LAA Alert for some models of Rotax Engines 1 Mar 2025 LAA Alert A-02-2025 has been published on the LAA website (and is also attached), highlighting a recent service bulletin published by Rotax regarding the inspection and/or replacement of the crankcase and/or gearbox housing on affected engines. Rotax has identified a potential manufacturing issue affecting the hardness values of the crankcase and/or gearbox housing materials in certain engines. These components may not meet the required specifications for material hardness, which could lead to reduced component durability and/or potential oil leakage. Rotax regards this bulletin as mandatory. A-02-2025 - Rotax Crankcase .pdf Download PDF • 220KB Next Previous

< Back Mandatory Technical Directive issued for Eurofox aircraft 6 Dec 2024 Inspection of Trim Tab Operating Cable Attachment to Prevent In-Flight Failures and replacement with Improved Design of Cable Attachment In 2016, the LAA issued an Alert, LAA/AWA/16/08 , regarding reported problems with the thin stranded steel elevator trim cable on Eurofox aircraft fraying at the attachment point to the trim tab operating horn, where the design forced the cable to be bent around the sharp edges of the clevis. The 2016 Alert also provided a link to, and served to promulgate, the Eurofox UK Service Bulletin on the subject, SB 04/2016 . Recently we’ve been advised of a potentially serious incident of elevator flutter on a Eurofox while towing a glider, which was caused by the trim cable failing altogether in flight where it passes around the trim tab operating horn clevis. This resulted in violent shaking of the elevator with serious potential for structural damage or loss of control. Since the cable had evidently frayed considerably before failing altogether, this occurrence highlights the importance inspecting the trim cable for signs of fraying at this point at each pre-flight and maintenance check, and, as the service bulletin explains, of keeping the clevis free-moving about its attachment to the tab so the clevis remains in line with the cable as the tab moves. This minimises the relative movement between the two which if occurring, would accelerate the wear on the cable. Eurofox UK advises that since the issue of the 2016 Service Bulletin, they have revised the design of the cable attachment clevis so that the cable now passes around a circular bush rather than being forced into two sharp bends, which reduces the wear on the cable and tendency to fray and eventually break. MTD-07-2024 , issued today, requires Owners/Operators to check whether the old or new design of clevises are fitted and for any signs of trim cable fraying before further flight. Owners/Operators must obtain and use a copy of the up-issued AEROPRO Checklist - B Service/Maintenance plan (Update Nov 2024 LAA aircraft) before the next 50-hour check. Finally, the trim cable system must be replaced immediately if any trim cable fraying is found, as detailed in the MTD. Furthermore, all Eurofoxes with the old-style of clevis must have the trim cable system replaced, as described in the MTD, by 1st June 2025.

Detail Design Having worked out a promising-looking layout, initial three-view and performance and weight specifications, now is the stage where the hard work begins of transforming concepts to working drawings. Essential decisions have to be made about types of material to be used, the structural arrangement, exact choice of powerplant and so on. You’ll probably need to make a cockpit mock-up to check the ergonomics and control system arrangements, and maybe build a flying radio controlled model of the design to give faith in the handling characteristics. With the basic geometry laid out, stress calculations and assembly drawings come next, then drawings of individual piece parts. Keep an up-to-date tally on weights. As the drawings get more detailed you must re-evaluate whether you are going to meet your original targets in terms of weight, strength and aerodynamic cleanliness, whether you need to re-visit your original assumptions or re-design from scratch. Is there a way that the part or assembly can be made more easily, more cheaply, lighter, stronger, more fatigue or corrosion resistant? Fewer parts and fewer joints generally means fewer problems and less weight. Can you use off the shelf parts rather than having to make them specially? Are there other aeroplanes around that have already solved a particular problem in a clever way? Will the aircraft be easy to inspect in service, easy to repair if it gets damaged? Can it be broken down for transportation? If the handling isn’t quite right when the prototype is test flown, does the design make provision for ‘tweaks’ to put it right? Does the design include reserves of strength to cope with weight growth in service and more powerful engines, or is everything pared down to the minimum? Design Tutorials

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.

< Back MTD-03-2025 - Marquart Charger Aileron Slave Strut 25 Jul 2025 LAA MTD-03-2025 - Marquart Charger Aileron Slave Strut The starboard aileron slave strut on Marquart Charger G-BHBT failed at the AN490 threaded fitting welded into the bottom end. A large proportion of the cross-section was cracked due to fatigue prior to final failure. The root cause of the fatigue cracking was probably flutter. Due to the difficulty of reliably inspecting for fatigue cracking at the base of threads, it has been decided to withdraw this strut design from the UK fleet.
