< 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 Mandatory Technical Directive issued for Sting S4 29 Sept 2023 LAA has been working with TL StingUK to correct an issue found during the flight testing of the factory-built version of the aircraft. It was found that the type would consistently drop the starboard wing more than the permitted maximum during a wings-level stall. LAA Mandatory Technical Directive MTD-01-2023 has been issued that requires the installation of a stall strip on the starboard wing and two stall strips on the port wing, along with restricting the elevator travel, in accodance with TL StingUK service bulletins 0002 and 0003, before further flight.

< Back MTD-04-2025 upissued to Issue 2 - Rans Control Linkage Rod End Connector Safety Washers 18 Nov 2025 MTD-04-2025 Issue 2 - Rans Control Linkage Rod End Connector Safety Washers MTD-04-2025 Issue 1 was recently published to mandate the replacement of all plastic control linkage rod end connector washers with metal washers . It has become apparent that the washers specified in this MTD are not suitable to replace the plastic washers due to their dimensions. MTD-04-2025 Issue 2 has been raised in order to amend the specification of the metal washers that must used to replace plastic washers. Therefore, MTD-04-2025 Issue 2 supersedes Issue 1. Issue 1 of this MTD is now cancelled. Please refer to the attached MTD document for full details and compliance instructions, which can also be found on the LAA website HERE .

< Back Alert A-04-2025 - Jabiru Flywheel Bolts 12 Jun 2025 LAA Alert A-04-2025 - Jabiru Flywheel Bolts LAA Alert A-04-2025 has been published on the LAA website (and is also attached), highlighting the Installation Procedure, Torque Checks and Replacement Interval for Flywheel Attachment Bolts on aircraft equipped with Jabiru 2200, 3300 and 5100 engines, and withdrawal of LAA Alert AWA/20/15. With the advice in JSB-012 (Issue 9 onward) having been promulgated by Jabiru, LAA has withdrawn Alert AWA/20/15, which means that provided the advice in JSB-012 Issue 9 or subsequent is followed, along with regular bolt torque checks at every 100 hours and annual check as called for in the Engine Maintenance Manual, the recommended bolt life is as stated in the Engine Maintenance Manual (currently 500 hrs). For LAA aircraft having the flywheel bolts replaced, or torque checked, the work must be overseen and signed-for by a suitably approved LAA Inspector. Engine logbook entries must be made and certified with a PMR statement referencing JSB-012 in the logbook white pages, as well as an entry in the logbook pink pages (or equivalent method for tracking continued airworthiness compliance).

< 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.
