## Summary

This document proposes to revise an existing airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A109C, A109E, and A109K2 helicopters. That AD currently requires inspecting the main rotor blade (blade) tip cap for bonding separation and a crack, and also requires a tap inspection of the tip cap for bonding separation in the blade bond area and a dye penetrant inspection of the tip cap leading edge along the welded joint line of the upper and lower tip cap skin shells for a crack. This action would require those same actions, but would correct a blade part number (P/N) that was stated incorrectly in the Applicability section of the existing AD. This proposal is prompted by the need to correct a blade P/N. The actions specified by the proposed AD are intended to prevent failure of a blade tip cap, excessive vibration, and subsequent loss of control of the helicopter.
