AD 97-18-08 62 FR 46184 Active

This amendment adopts a new airworthiness directive (AD) that is applicable to certain British Aerospace (Jetstream) Model 4101 airplanes. This action requires a visual inspection to detect wear damage of the drag brace of the main landing gear (MLG), and replacement of any worn parts with new or serviceable parts. This action also requires an inspection to determine whether there is movement in the spherical bearing of the lower link of the drag brace, certain measurements of the drag brace, and repetitive inspections, if necessary. This amendment is prompted by reports of loose spherical bearings in the links of the drag brace of the MLG. The actions specified in this AD are intended to prevent reduced structural integrity and potential collapse of the MLG due to loose spherical bearings and subsequent wear damage of the links of the drag brace.
