< 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 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.
