Affects Main Landing Gear On AB139 And AW139 Models
On November 11, 2024, the European Union Aviation Safety Agency issued an Emergency Airworthiness Directive (EAD) affecting all serial numbers of AB139 and AW139 helicopters. The AD affects the main landing gear (MLG) shock absorber assembly. There have been reported instances of a broken eye end of the MLG shock absorber piston rod, which subsequent investigation determined the cause was fatigue cracking.
