< Back LAA Alert issued for Lycoming Engines 28 Nov 2024 The LAA has issued Alert A-02-2024 (link below) to highlight the recent Lycoming Airworthiness Directive regarding connecting rod bushings and connecting rod assemblies. The FAA has issued a new airworthiness directive (AD) for models of Lycoming engines that have an affected part installed and are assembled within the ship date range, as specified in Table 1 to paragraph (c) of this Airworthiness Directive (AD 2024-21-02). The AD comes into effect on 5th December 2024. This AD was prompted by several reports of connecting rod failures which resulted in uncontained engine failure and in-flight shutdowns. The AD requires repetitive oil inspections for bronze metal particulates at each oil change, and if found, additional inspections of the connecting rod bushings for damage, proper fit, movement, and wear, and replacement if necessary. The first oil inspection must take at the next oil change or within 4 months after the AD becomes effective i.e. 5th April 2025, whichever occurs first. As terminating action to the connecting rod bushing inspections, this AD requires replacement of the connecting rod bushings with parts eligible for installation.

< Back MTD-03-2025 - Marquart Charger Aileron Slave Strut 25 Jul 2025 LAA MTD-03-2025 - Marquart Charger Aileron Slave Strut The starboard aileron slave strut on Marquart Charger G-BHBT failed at the AN490 threaded fitting welded into the bottom end. A large proportion of the cross-section was cracked due to fatigue prior to final failure. The root cause of the fatigue cracking was probably flutter. Due to the difficulty of reliably inspecting for fatigue cracking at the base of threads, it has been decided to withdraw this strut design from the UK fleet.

< Back New LAA Inspectors - Umberto Izzo & Simon Boynett 26 Jan 2024 It is time to introduce you to two more new LAA Inspectors - Umberto Izzo and Simon Boynett, who both attended an LAA Inspector Assessment Day in December, with our Chief Inspector, Lucy. Umberto's experience is mainly in general aviation and microlight aircraft (metal, fabric and composites), either Lycoming, Continental or Rotax-powered. He is also IRMT-approved. He owns a share in Jodel 1050. Simon is a retired Licensed Aircraft Engineer with 44 years of experience working on Commercial Passenger and Cargo aircraft. He has a B1 and B2 CAA licence (Airframes, Engines and Electrical generation systems) B2 (Avionics, Auto flight, Auto land systems, Radio and Radar). In addition to this, he has an FAA issued A & P licence. He put a lot of blood, sweat and tears into building his own Vans RV 7, that he still loves to fly today as often as he can. Although retired, he still has aeroplanes and safety in his blood and looks forward to helping others to keep the high standards the LAA require, and to advise and certify Maintenance and Permit to Fly revalidation inspections.

< 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 International Women in Engineering Day 23 Jun 2023 To mark this year’s International Women in Engineering Day, the UK Civil Aviation Authority had a chat with Lucy Wootton, our Chief Inspector. Simon Tilling, our CEO said: “The LAA are really proud of Lucy and the work she is doing to improve the service we offer to our members. We would be very keen to hear from more women who want to consider a career in light aviation” Learn more about how Lucy’s career has developed to encompass gliding, powered flying and aeronautical engineering.

< 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

< Back Gyroplanes to join the new online Permit Revalidation System 17 Jun 2025 The new online Permit Revalidation system has been in place for fixed-wing aircraft on the LAA fleet since 15th April 2025 and now it is time to add Gyroplanes, both amateur-built and factory-built. Therefore, we are pleased to announce that gyroplane Owners and Inspectors will be able to use the online Permit Revalidation system from 22nd July 2025! The Permit Revalidation Process for gyroplanes will follow the same three steps as for fixed-wing aircraft, shown in the graphic below. The only differences will be small changes to the questions in line with the requirements for gyroplanes, such as asking about the rotor and rotor-head. Where do I find more information? If you are a Gyroplane Owner or Inspector, then please talk to your friends that own and inspect fixed-wing aircraft, as many of them will have been through this new process. There is lots of information to help you: Technical Leaflet 2.00 – Revalidating an Aircraft’s Permit to Fly , will be updated on 22nd July to include information regarding gyroplanes A detailed step-by-step video guide is available on the LAA’s YouTube channel, called ‘ Online Permit Revalidation Explained .’ A list of Frequently Asked Questions is available on the LAA website. Again, these will be updated on 22nd July to include Gyroplanes For more information, click HERE . Note: the 22nd July is a hard deadline, so LAA Engineering will not accept applications made under the old system from that date. Changes to Permit Revalidation Fees for Gyroplane Owners From 22nd July, Permit Revalidation Fees for gyroplanes will be based on Maximum Take Off Weight (MTOW), rather than Factory Built Gyroplanes always having a fee of £323. This is in line with the charging regime for fixed-wing aircraft. The current charges are as follows: Up to 450kg - £241 451-999kg - £292 1000kg & above - £323 Note: For FBGs - if the last Permit revalidation was not administered by the LAA, an extra fee of £155 applies Next Previous

< Back MTD-05-2025 Eurofox Rudder Pedal Cracking 19 Nov 2025 MTD-05-2025 Eurofox Rudder Pedal Cracking - Mandatory Inspection requirements, which must be completed before your next flight There have been two reported instances in the UK of Eurofox aircraft experiencing cracking at the right-foot rudder pedal on the starboard seat side, where it is welded to the rudder pedal torque tube, leading to the pedal no longer being rigidly attached to the torque tube. On at least one of these instances, aircraft handling was negatively affected, reducing yaw authority and seriously degrading flight safety. Note that failure of the starboard side right-foot rudder pedal results in loss of rudder control, even when the aircraft is flown from the Pilot in Command position i.e. from the port seat side. Please refer to the MTD-05-2025 document below for full details of the mandatory inspection requirements, which must be completed before your next flight and subsequently at intervals not exceeding 10 flight-hours or the next Permit Revalidation inspection, whichever occurs first.
