< Back Van's Aircraft laser-cut parts - update 20 Oct 2023 Since our mention of this issue in the August edition of Light Aviation , Van’s Aircraft have been toiling away analysing and testing various structural elements to establish the effect that the laser cutting of parts has had on their strength and fatigue life. Detailed updates can be found on their website, but understandably UK builders and operators are seeking clarity on what the endgame will be on this issue. As the issue generally affects potential fatigue life, there is no immediate need to take action. In discussion with Rian Johnson, Van’s President and Chief Engineer, he tells us that they’re working on service information for the fleet that they expect to be published by the end of the year. Having worked closely with Van’s over many years, our expectation is that we will endorse their position. Next Previous

< Back Mandatory Technical Directive issued for Pioneer aircraft 6 Mar 2024 The control horn on the elevator trim tab on a Pioneer 300 failed in flight, which resulted in sever trim tab flutter. A safe landing was made and there was no further damage to the aircraft. MTD-02-2024 requires the checking of this horn on all Pioneer variants to ensure that it is of the correct design standard and recommends regular checks for free-play in the system. 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.

< 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 The New Permit Revalidation System - Step-by-Step Guide 9 Apr 2025 The new LAA Permit to Fly revalidation system will go live on 15th April 2025. This streamlined, fully online process offers an easier and faster way for aircraft Owners and Inspectors to handle Permit to Fly revalidations. Watch this video for a step-by-step guide on how to complete the online Permit Revalidation process, both as an Owner and as an Inspector. https://www.youtube.com/watch?v=rOGRQ89dOA8 There are a few key considerations to ensure your revalidation under the new system goes smoothly: Please make sure you know your username and password before applying for your aircraft’s revalidation. If you have forgotten your login details, please contact the LAA Office. All aircraft using the new system for the first time will require a check flight no older than 3 months at the time you submit the revalidation application. This is in order to provide a baseline for the online system. The 3-year check flight schedule will then apply subsequently to most aircraft types. Some aircraft will still require a check flight at every revalidation, these are: Aircraft cleared for glider tugging in their Operating Limitations document. Aircraft cleared for Night/IFR. Aircraft which have flown less than 12 hours since the previous revalidation inspection. You will not have to submit your CFS-1 Check Flight Schedule when applying through the new system. However, a CFS-1 will need to be completed for each check flight and stored with the aircraft’s documentation, so that it is available when needed. We encourage you submit your revalidation application through the new online system, as processing time is expected to be faster than an ‘old-style’ revalidation. If you still wish to make an ‘old-style’ application up until 15th May 2025, all 3 forms must be submitted by this date and you will only transition to the 3-year check flight schedule after your first revalidation through the new system. Note: The option to apply for revalidation in ‘My Aircraft Data’ on the LAA website may appear shortly before the go-live date on 15th April 2025 as our IT infrastructure is updated. However, we will only be able to process applications received on or after the official go-live date.

< Back Mandatory Technical Directive issued for many Zenair types 14 Jan 2025 MTD-01-2025 - 'Inspection of horizontal stabiliser (tailplane) attachment brackets and associated hardware for cracks, looseness and other forms of distress' is issued for Zenair CH601, CH650, CH701, CH750 and variants of these four models. 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. MTD-01-2025 - Zenair Tailplane Brackets .pdf Download PDF • 162KB Next Previous
