## Summary

This document proposes adopting a new airworthiness directive (AD) for MD Helicopters, Inc. (MDHI) Model 369A, OH-6A, 369D, 369E, 369F, 369FF, 369H, 369HE, 369HM, and 369HS helicopters. The proposed AD would require repetitive tap inspections of each tail rotor (T/R) blade abrasion strip. This proposal is prompted by an incident in which an abrasion strip separated from a T/R blade. The actions specified by the proposed AD are intended to prevent disbonding and subsequent separation of an abrasion strip from a T/R blade, which could result in vibration, loss of the T/R, and subsequent loss of control of the helicopter.
