## Abstract

We are adopting a new airworthiness directive (AD) for the PZL Swidnik S. A. (PZL) Model W-3A helicopters. This AD results from mandatory continuing airworthiness information (MCAI) issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The MCAI states: "In PZL W-3A helicopter S/N 37.07.05, and previously also in the PZL W-3AS model helicopters, leakage was found in the pipe 37.59.006.00.00 installed in the pressure line of hydraulic system 2, in the part between the hydraulic block and the ground hydraulic unit panel. The hydraulic system in the part between hydraulic blocks and the ground hydraulic unit panel is used only during periodical inspections, for the performance of which it is required to use the hydraulic power unit. This condition, if not corrected, could result in a fire hazard." The actions specified in this AD are intended to prevent this unsafe condition.
