< Back Inspector Renewal 19 Mar 2024 It's that time of year again! LAA Inspector Authorisations lapse at the end of this month. Renewing is simple, available both on and offline. In order to renew this year, Inspectors need to carry out two simple steps, which are as follows: Complete and sign the ' Inspector Declaration, ' which was emailed to all Inspectors on 4th March, and return to LAA Engineering, either as a scanned document or in the post. Pay the Inspector Renewal Fee , which is £40 and covers administration of an Inspector Authorisation throughout the year. (For Inspectors of Factory Built Gyroplanes, there is no longer an additional fee. All Inspectors pay £40). Inspectors can pay via the LAA shop, found here , or by giving us a call with their payment card details. Alternatively, Inspectors can pay by Bank Transfer. Inspectors' continuing support is crucial and we sincerely hope that all Inspectors will renew. Next Previous

< Back LAA Alert A-02-2026 - MCR-01 Tailplane Mounting Corrosion 23 Jul 2026 Alert A-02-2026 - MCR-01 Corrosion of Aluminium Alloy Wing and Tailplane Attachment Brackets This Alert has been issued following the discovery of significant corrosion affecting the tailplane attachment brackets on an MCR-01 aircraft. Owners should mitigate the risk by rigorous inspections and taking suitable preventative measures. In addition to the existing requirement for periodic wing removal and inspection, we strongly recommend that the tailplane is also removed at the similar intervals for clearer view of the attachments. Owners of MCR-01 aircraft are strongly advised to include this advice in their aircraft’s maintenance schedules. Please refer to the Alert A-02-2026 HERE or below for full details and recommended checks. A-02-2026 - MCR-01 Tailplane Mounting Corrosion .pdf Download PDF • 319KB Next Previous

< 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.

< Back MTD-06-2024 Issue 2 - Pietenpol Air Camper Wing Rear Strut Internal Corrosion 24 Jul 2026 MTD-06-2024 Issue 2 – Pietenpol Air Camper Wing Rear Strut Internal Corrosion Issue 1 of this MTD, issued in 2024, required inspection of the rear 'Jim Wills' type struts for corrosion, replacement of any corroded struts, and the drilling of a single drain hole in the end cap of each strut. MTD-06-2024 Issue 2 supersedes Issue 1 and introduces revised drain hole requirements based on feedback from the field. Aircraft fitted with Jim Wills rear wing struts must have the struts inspected for internal and external corrosion. For aircraft that have not previously complied with Issue 1, the requirements of Issue 2 must be completed before next flight. For aircraft that have already complied with Issue 1, the additional requirements introduced in Issue 2 must be completed by 31st December 2027. Please refer to the MTD-06-2024 Issue 2 document for full applicability, aircraft identification guidance, and compliance requirements.

< 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 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
