Airworthiness Directives; Dornier Model 328-100 Series Airplanes Equipped With Burns Aerospace Corporation Passenger Seats

This amendment revises an existing airworthiness directive (AD), applicable to certain Dornier Model 328-100 series airplanes, that currently requires modification of the restraining systems of certain passenger seats by replacing anchor point fasteners with fasteners that are able to withstand required 16g load conditions. That AD was prompted by a report indicating that the restraining systems on these seats failed to meet 16g test load requirements during dynamic testing. The actions specified by that AD are intended to prevent the fasteners from failing, which could result in release of the seat restraint and consequent injury to passengers. This amendment revises the applicability of the existing AD to specify serial numbers of the affected passenger seats.
