< 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

< 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 A-15-2025 Glasair Rudder Pedal Bearing Failures 23 Dec 2025 LAA Alert A-15-2025 Glasair Rudder Pedal Bearing Failures A recent social media report has brought attention to two rudder pedal bearing failure events on a non-LAA Glasair. These bearings attach each rudder pedal assembly to the bearing support ribs. Owners and Inspectors should carry out frequent inspections of these bearings for signs of cracking, breaking, excessive play or any other abnormalities. Pilots should also conduct effective full-and-free movement checks during taxiing to ensure correct rudder pedal operation prior to take-off. If there are any doubts on the bearings’ condition, age, or origin, they should be replaced with newly made ones. Instructions on how to make new bearings from a 3/4" UHMWPE sheet can be found in the Stoddard-Hamilton Instruction Manual. Please refer to the LAA Alert A-15-2025 HERE or below for full details and recommended checks. A-15-2025 Glasair Rudder Pedal Bearing Failures .pdf Download PDF • 309KB Next Previous

< Back New LAA Inspector - Tomas del Carpio 15 Aug 2025 We are pleased to welcome Tomas del Carpio as a new LAA Inspector, having attended an LAA Inspector Assessment Day at Turweston recently. Living in the historic village of the former RAF Upper Heyford base, aviation is a part of Tomas’ life even outside of my daily job of restoring and maintaining vintage and modern light aircraft. He has been in the aircraft maintenance industry since 2008 but the age range of aircraft. He has worked on spans more than a century of aviation history. From helping to restore an original AVRO 504 to carrying out advanced composite carbon fibre repairs on a Diamond DA42, his experience covers a broad and diverse spectrum of aircraft types and technologies - both certified and non-certified. Whether it’s performing an engine change on a King Air in the dusty heat of Malta or changing a tyre on a stranded PA-28 in a muddy field in Kent, He has encountered a wide variety of challenges and learned something valuable from each one. Tomas is always happy to help and share his knowledge and experience whether it’s offering technical advice over the phone or getting hands-on with something more involved. Next Previous

< Back Eurofox Rudder Pedal Failures - LAA Standard Modification Approved & MTD-05-2025 Issue 4 19 Jan 2026 LAA Standard Modification SM16826 provides a terminating action to the 10-hour inspections required in LAA MTD-05-2025, which has now been up-issued to ISSUE 4 The LAA Standard Modification – SM16826 ‘ Reinforcement of Rudder Pedal to Torque Tube Joints ’ has been through our internal review process and is now formally approved. SM16826 strengthens all 4 pedal joints by the addition of welded steel, wrap-around finger plates. Incorporating this standard modification provides a terminating action to the 10-hour inspections required in LAA MTD-05-2025, which has now been up-issued to Issue 4. The CAA have also confirmed that incorporating this modification will be a terminating action for CAA MPD-2026-002-E and we expect the MPD to be upissued this week to reflect this. Once Standard Modification SM16826 is completed, owners will need to submit an LAA/MOD 1 Form ( Standard Mod Incorporation ) to let us know that the modification has been embodied, so that we can update our records at LAA HQ. A copy of Form LAA/MOD 1 is here . As a CAA-approved welder is required for this modification, owners have been provided with a list of CAA welders known to the LAA.
