This AD applies to all PZL Świdnik S.A. Model PZL W-3A helicopters, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all PZL [Sacute]widnik S.A. Model PZL W-3A helicopters. This AD was prompted by a report of a cracked nose landing gear (NLG) bellcrank assembly. This AD requires a one-time inspection of the NLG bellcrank assembly for discrepancies and replacement if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
For purposes of this AD, affected NLG bellcrank assemblies have part number (P/N) 30.42.010.00.00.

For purposes of this AD, a “landing” is counted any time the helicopter lifts off into the air and then lands again regardless of the duration of the landing and regardless of whether the engine is shut down.
During the inspection required by paragraph (h) of this AD, if the NLG bellcrank assembly meets the criteria for replacement, as specified in Chapter II, paragraph 3., of Bulletin BO-37-18-292: Before further flight, replace the affected NLG bellcrank assembly and do all related investigative and corrective actions, in accordance with Chapter II, paragraph 4., of Bulletin BO-37-18-292.
As of the effective date of this AD: Do not install a bellcrank NLG assembly, P/N 30.42.010.00.00, on any helicopter unless the assembly has passed an inspection (no defects found), in accordance with paragraph (h) of this AD.
