< Back MTD-04-2025 published Rans Control Linkage Rod End Connector Washers 13 Nov 2025 MTD-04-2025 - Replacement of all plastic control linkage rod end connector washers with metal washers During an inspection of an early Rans S6, all plastic washers between the bolt and bearing of the flap and aileron control linkage rod end connectors were found to be split or missing. This issue is identified in Rans’ service bulletin 012390-03. As plastic washers are susceptible to failure due to wear and embrittlement, this MTD is raised to mandate the replacement of all plastic control linkage rod end connector washers with metal washers. These washers prevent the rod end from disconnecting in the event of bearing failure. The washers fitted must be larger than the diameter of the bearing. Refer to here for a diagram. MTD-04-2025 can be found here and is found below. Note: Do not re-use nyloc or other self-locking nuts if their locking ability has become compromised.

< Back Alert 05-2024 - Rotax Oil Spray Nozzles - upissued to Issue 2 24 Jul 2025 LAA Alert 05-2024 - Inspection and/or Replacement of Oil Spray Nozzle in some Rotax 900 series engines - upissued to Issue 2 On 16.12.24, Rotax issued a MANDATORY Service Bulletins SB 912 i-016/SB 915 i-016 / SB 916 i-006 and SB-912 i-016iS / SB-915 i-016iS / SB-916 i-006iS which call for urgent action for engines of specified models within certain serial number ranges, if the engine has run for less than 200 hours from new, or engines which have been fitted with specific overhaul kits supplied between 01.01.22 and 31.10.24 inclusive. Therefore, LAA Alert A-05-2024 was issued on 17th December 2024 regarding this. Subsequently, a revision to the Rotax Service Bulletins was issued on 20.12.24, entitled MANDATORY Alert Service Bulletins ASB 912 i-016 R1/ASB 915 i-016 R1 / ASB 916 i-006 R1 and ASB-912 i-016iS R1 / ASB-915 i-016iS R1 and ASB-916 i 006iS R1. Therefore, on 23rd July 2025, LAA Alert A-05-2024 was upissued to Issue 2, which now supersedes Issue 1. A-05-2024 Issue 2 can be found HERE and is also found below. The bulletin concerns problems with a possible full or partial blockage of the oil spray nozzle due to an excessive application of Loctite at the manufacturing stage, when assembling the sprag clutch housing. This can lead to inadequate cooling of the stator assembly, potentially causing loss of electrical power to the engine’s ECU.

< Back Nick Stone appointed as the LAA's Head of Airworthiness 24 Oct 2023 The LAA is pleased to announce the appointment of Nick Stone as the LAA’s Head of Airworthiness. Nick brings a vast wealth of aircraft knowledge as well as a real world understanding of the need for good process and procedure. Having started his career in the Royal Air Force, Nick went on to work in the aerospace industry working in the UK with British Aerospace and Slingsby Aviation at various sites and projects, as an inspector, methods engineer and quality engineer. Nick then moved to the United States at Eastern Airlines in Miami Florida, Learjet in Wichita Kansas and Chihuahua Mexico as inspection/Quality representative of Shorts Aerospace (Bombardier Aerospace). Following a downturn in the British Aerospace industry he then took an opportunity to move into the nuclear industry working in both reprocessing and power generation. Throughout Nick's working life the one constant has been a passion for aviation. Having started as a volunteer at a local aircraft museum at 14, Nick started flying at the age of 16 in gliders and has a private pilot’s licence PPL(A). Prior to becoming an LAA inspector Nick spent many years building, rebuilding, and restoring vintage aircraft, the more unusual the better. “As an LAA inspector I understand the need to move forward and change and adapt to an ever changing but exciting world. Having run my own aircraft restoration company for the last seven years I always felt it is important to understand your customers”. LAA CEO Simon Tilling said, “Nick is a great addition to the LAA staff. I and the rest of the team are looking forward to working with him in the near future” Next Previous

< 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 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

Air to Ground Radio Operator's Course Price Member - £320, Non-Member - £340 (Additional fee of £50 to CAA for ROCC certificate) Duration Day 1: 09:15 for 09:30 PROMPT start. Finish 17:00 (approx). Day 2: 08:30 PROMPT start. Finish 16:00 < Back About the Course About the Course This course, held at Popham Airfield is hosted by Chris Thompson, an experienced AGCS person, CAA examiner, and LAA member. It will provide both the theoretical and practical training required to sit the examinations for the CAA Radio Operator's Certificate of Competence (ROCC) qualification required by operators of ground-based radio equipment at flying sites and events where an air-to-ground radio service is provided. The course is in two parts. Day One is made up of the core training and radio procedures practice on simulated ground-to-air communications. Day Two will consist of the CAA written and practical examinations which will allow candidates to directly apply for the CAA ROCC Certificate. Why two days? This course spends a good deal of time giving background to your practical usage of the ROCC Certificate. The Practical exam is highly developed to give a representation of what it is like to operate an Air/Ground service when you commence any future employment. All delegates SHOULD have some basic knowledge of GA airfield circuit procedures and a level 6 English language proficiency or you may find this course difficult. AGCS RADIO OPERATOR'S CERTIFICATE OF COMPETANCE - IMPORTANT NOTES: Note 1 - This Course is to enable a person to operate a Ground Radio Station running AGCS (Air-Ground-Communication-Service) and not be confused with an aircraft FRTOL (the Flight Radio Telephony Operator Licence, which is required to operate the radio in an aircraft). Note 2 - All ROCC Certificates currently in existence are valid until 31st December 2028. The CAA CAP2192 (July 2021) stating an end date of 31st December 2025 is no longer valid and has been superseded. Note 3 - All new ROCC issued will be valid until 31st December 2028. The revalidation process is under review by the CAA and will be notified here when available. Note 4 - The only pre-requisites that the CAA state for an ROCC “Air Ground” Course are that the applicant should be over the age of 18 and pass the exams. The CAA are no longer using the “paper” application process and are now only using the CAA online Portal. You must have a CAA Portal Username and Verified ID to submit your ROCC application. This can be done by visiting the CAA Portal (search Google for https://portal.caa.co.uk .) website and supplying them with the required documentation. The instructions for this are on the CAA website and not part of the LAA course process. Note 5 -You will be asked to bring your verified Portal Username to the course. Without this, any exam results will not be able to be processed by your Examiner and the CAA. Note 6 - The course also assumes that you speak English to level 6 (CEFR/C2) and that you will have a basic understanding of airfield and light aircraft circuit procedures, hence a "pilot" background is best. Note 7 - This AGCS ROCC "Air/Ground" course should not be confused with other ROCC types, OCS, PARA,CDO, FDD, and OPC as these are not part of the LAA mandate. Note 8 - There will be an additional fee of £50.00 to the CAA for the issue of the ROCC certificate.
