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. MTD-03-2025 can be found HERE and is found below.
