A design deficiency has been identified, affecting some specific main cabin floor panel installations on AB139 and AW139 helicopters. This condition, if not corrected, could, in case of an emergency landing, lead to failure of the affected seats, as defined in this AD, possibly resulting in injury to helicopter occupants. To address this potential unsafe condition, as a temporary measure, until an improved cabin floor panel design solution is made available, Leonardo identified the affected configurations and helicopters, and published the ASB, providing seat removal instructions.
For the reasons described above, this AD requires removal of the affected seat(s).
