< Back Mandatory Technical Directive issued for Jabiru 2200 engines 10 Jul 2024 Mandatory Technical Directive, MTD-05-2024 has been issued today to introduce mandatory checks on the clearance between the distributor cap and rotor arm in Jabiru 2200 engines where the cap or rotor have recently been changed (or following subsequent changes). This follows an in-service finding where differences in distributor cap design were found which lead to extreme wear in the components causing the engine to stop. The MTD must be carried out before further running of the engine on or after 10th July 2024 on Jabiru 2200 engines where the distributor cap and/or rotor arm has been changed in the last 20 engine hours, or are subsequently changed. The checks are also recommended on all other Jabiru 2200 engines. Next Previous

< Back New LAA Inspector - Ben Davis 27 Nov 2025 We are pleased to welcome Ben Davis as a new LAA Inspector, having attended an LAA Inspector Assessment Day at Turweston recently. Ben has been an aircraft owner for about twenty years and has become something of a fan of the (mighty) Alpi Pioneer series. He’s owned several and flown several more. Ben has also refurbished and upgraded a number of Pioneers with new avionics, autopilots, and instruments. Along the way, he has owned and improved a Europa and a few other types, but he always seems to find his way back to a Pioneer! Ben also enjoys staring out of the front window of little biz jets. With a background in electronics, moving into avionics was a natural step for him. Ben is a Rotax iRMT (Line & Heavy), a BMAA Inspector, and now also an LAA Inspector, combining his technical background with years of hands-on experience. Ben is based at Finmere, just a short hop from LAA HQ, and is always happy to help other owners with maintenance, upgrades, or just a good aviation chat. You can find him sharing projects and flying adventures on social media as @benfly79. Next Previous

< 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 uAVionix AV30E approved as a back-up EFIS 8 Jun 2023 We've recently added the uAvionix AV30E to our list of approved backup EFIS units for use in Permit aircraft. The EFIS units listed in TL3.20 may be used without further reference to LAA Engineering, although your LAA inspector will need to make a Permit Maintenance Release (PMR) entry in the airframe logbook quoting this Technical Leaflet reference.

< Back LAA Alert A-14-2025 - Eurofox Fuel Line Disconnected In-Flight 11 Dec 2025 LAA Alert A-14-2025 - Eurofox Fuel Line Disconnected In-Flight A non-LAA, Factory-Built Eurofox with a Rotax 915, fuel-injected engine experienced an in-flight engine shut down due to the high pressure (4.5 Bar) fuel hose connecting the high-pressure fuel pump unit to the master fuel valve becoming detached from the master fuel valve during flight. This resulted in the engine stopping and a serious fuel leak in the cockpit. It is believed that a combination of the fitting’s shallow barbs, and a small fuel leak of high-pressure fuel through the scratched/cut hose lubricated the fitting’s brass surface and allowed the hose to slide off the fitting. Owners and Inspectors should pay close attention to fuel hose condition and attachment security during inspections. Any signs of movement, wear, or mismatch between hose and fitting must be addressed before the aircraft flies again. Please refer to the attached Alert here for full details and recommended checks.

< 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 Van's Aircraft laser-cut parts - update 20 Oct 2023 Since our mention of this issue in the August edition of Light Aviation , Van’s Aircraft have been toiling away analysing and testing various structural elements to establish the effect that the laser cutting of parts has had on their strength and fatigue life. Detailed updates can be found on their website, but understandably UK builders and operators are seeking clarity on what the endgame will be on this issue. As the issue generally affects potential fatigue life, there is no immediate need to take action. In discussion with Rian Johnson, Van’s President and Chief Engineer, he tells us that they’re working on service information for the fleet that they expect to be published by the end of the year. Having worked closely with Van’s over many years, our expectation is that we will endorse their position. Next Previous

< Back New LAA Inspector - Ian Pattingale 6 Feb 2024 It is time to introduce you to the final new LAA Inspector from the recent batch of LAA Inspector Assessment Days - Ian Pattingale. Ian spent 9 years in the RAF as a propulsion technician, after a brief spell as a Development Engineer. He then spent the following 30 years at British Airways in various roles from aircraft Technical Instructor to B737 Flight Test Engineer. His current job is as an Engineer in London Heathrow Engineering Operations, where we are responsible for providing serviceable aircraft to support the flying programme. He's a keen glider pilot with a current 'Full Cat' instructor rating, as well as a 'Senior Inspector/Chief Engineer (ARC Signatory)' on wood, composite and metal airframes for gliders. In addition, he's a B1 Licensed, with current B777 ratings . As a member of the Vintage Gliding Club, Ian is keen to promote the continuing airworthiness of 'vintage' glider types - a current project that I am working on is the restoration of a 1976 Schleicher ASK18 to a fully airworthy flying condition.
