< Back MTD-01-2025 ISSUE 2 published - Zenair Tailplane Brackets 28 Aug 2025 MTD-01-2025 - 'Inspection of horizontal stabiliser (tailplane) attachment brackets and associated hardware for cracks, looseness and other forms of distress' for Zenair CH601, CH650, CH701, CH750 and variants of these four models has been upissued to Issue 2. This is in order to correct an error in the 'Effective Date' of this MTD. This MTD can be found HERE and is also available below. A number of cases have been found whereby the structural integrity of the horizontal stabiliser mountings on the Zenair types identified above have been compromised by one or more of the following: cracking of the attachment brackets oversize holes loose rivets distorted and chafed brackets. These problems could occur due to a number of factors including poor build quality, a build-up of tolerances in the positioning or dimensions of the brackets, improper assembly, rough treatment or in-flight vibration. Failure of a tailplane attachment could result in degraded controllability in flight or loss of control. Special inspections of this area have been recommended by Zenair since January 2017, in their document ‘Mandatory Action. Jan. 2017 – Inspection of Horizontal Stabilizer tail attachment brackets’. This Mandatory Technical Directive mandates this safety action for aircraft operating on LAA Permits to Fly. 20250828 - MTD-01-2025 - Zenair Tailplane Brackets - Issue 2 .pdf Download PDF • 183KB Next Previous

< Back LAA Alert - FAA issues AD for Piper rudder posts 14 Feb 2025 Replacement of rudder posts not made from 4130N On 13.02.25, FAA issued Airworthiness Directive 2025-02-11 which requires the replacement of the rudder post on a large number of Piper types, where the part is not made from 4130N steel. Compliance time varies between 2 years and 10 years depending on whether a beacon light is fitted to the top of the fin post and depending on the power of the engine installed. LAA Alert A-01-2025 has been created to communicate this to potentially affected owners. A-01-2025 Piper rudder post AD .pdf Download PDF • 196KB Next Previous

< Back LAA Alert A-13-2025 - CZAW SportCruiser Nose-Leg Failures 10 Dec 2025 LAA Alert A-13-2025 - CZAW SportCruiser Nose-Leg Failures LAA Engineering has issued Alert A-13-2025 to highlight the recent issues of SportCruiser Nose-Leg Failures. Two SportCruisers have recently suffered nose landing gear collapses, resulting in propeller strikes and airframe damage. Inspections have revealed evidence of cracking and possible weld-related weakness. Owners and Inspectors should carry out frequent checks for cracks, corrosion, and deformation on the nose-leg, paying particular attention to weld points. If any abnormalities are detected, the aircraft must not be flown and LAA Engineering contacted. Please refer to the Alert here for full details and recommended checks.

We provide a system whereby members can build an aircraft in the comfort of their own home (or wherever they choose) from either a set of plans or from a kit of parts. Every year around 100 newly-constructed aircraft are added to the LAA fleet, with members generally taking around 1 to 4 years to complete their kit projects. A whole range of aircraft is available to build, from single-seaters to four-seaters, aerobatic to amphibian, and WWI replica triplanes to gyroplanes. The LAA is tasked with ensuring that the designs members build meet minimum airworthiness requirements, appropriate to the type. Proposals for accepting other designs of aircraft can be put to the LAA, and a number of such types are accepted each year following a review of their airworthiness, amongst other things. This requires a member to champion the type through the process, arranging for the necessary technical information to be passed to the Engineering department and to build and test the first example. Similarly, it is possible for a member to build an aircraft of their own design. LAA provides support for this (see the Designing aircraft section), but due to limited resources only the most promising/developed designs can be advanced through the system. Building Aircraft One of the founding principles of the LAA is to provide for members wishing to build their own aircraft, either for their own education or to enable them to own an affordable aircraft. Of course, whichever type you choose it is usually possible to customise it to your liking using the LAA’s modification system. So if it’s an elaborate avionics suite that takes your fancy or an automotive engine conversion, there’s a route to investigating whether it’s possible. If you like the idea of building, but feel you lack the skills, then there are courses on various aspects of aircraft building to help bring you up to speed. Your Inspector is also a fantastic mine of information and generally will be your first port of call for technical information. Of course, the LAA also has a pool of full-time engineers who can be contacted for advice.

< 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.

< Back Mandatory Technical Directive issued for Jabiru 2200 engines 10 Jul 2024 Mandatory Technical Directive, MTD-05-2024 has been issued today to introduce mandatory checks on the clearance between the distributor cap and rotor arm in Jabiru 2200 engines where the cap or rotor have recently been changed (or following subsequent changes). This follows an in-service finding where differences in distributor cap design were found which lead to extreme wear in the components causing the engine to stop. The MTD must be carried out before further running of the engine on or after 10th July 2024 on Jabiru 2200 engines where the distributor cap and/or rotor arm has been changed in the last 20 engine hours, or are subsequently changed. The checks are also recommended on all other Jabiru 2200 engines. Next Previous

< 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
