< Back LAA Alert for Rotax 900 series engines regarding the oil spray nozzle 18 Dec 2024 Inspection and/or Replacement of Oil Spray Nozzle On 16.12.24, Rotax issued a new MANDATORY Service Bulletin SB 912 i-016/SB 915 i-016 / SB 916 i-006 which calls 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. 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 MTD-05-2024 - Jabiru Distributor Caps - Issue 2 23 Jul 2025 MTD-05-2024 - Jabiru Distributor Caps - has been upissued to Issue 2 today. This MTD can be found HERE and is also available below. On 10th July 2024, LAA Engineering published Issue 1 of MTD-05-2024. This was published due to apparent variations in the design of the distributor caps and rotor arms on Jabiru 2200 engines, which meant that, in some cases, there was insufficient clearance between the rotor arm and centre boss of the distributor cap, causing the contact button of the distributor cap to be flattened against its range of travel by the rotor arm, which causes extremely accelerated wear leading to ignition issues and potential engine failures. Today, Issue 2 of MTD-05-2024 has been issued, superseding Issue 1. Issue 1 of MTD-05-2024 detailed a method for ensuring sufficient clearance between the centre boss of the distributor cap and the rotor arm. This method has now been superseded by Jabiru’s Service Bulletin JSL050. LAA MTD-05-2024 Jabiru distributor cap Iss 2 .pdf Download PDF • 294KB 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 LAA Alert - FAA issues AD for Piper rudder posts 14 Feb 2025 Replacement of rudder posts not made from 4130N On 13.02.25, FAA issued Airworthiness Directive 2025-02-11 which requires the replacement of the rudder post on a large number of Piper types, where the part is not made from 4130N steel. Compliance time varies between 2 years and 10 years depending on whether a beacon light is fitted to the top of the fin post and depending on the power of the engine installed. LAA Alert A-01-2025 has been created to communicate this to potentially affected owners. A-01-2025 Piper rudder post AD .pdf Download PDF • 196KB 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.
