What to do

Operators must remove from service any affected pins before further flight—immediately for Model 204B, 205A, 205A-1, 205B, and 212 helicopters since August 24, 2021, and before further flight after February 16, 2022, for Model 210 helicopters. Installation of these pins is prohibited on all affected helicopters. Special flight permits are not allowed.

Summary

FAA Airworthiness Directive 2022-02-02 is a final rule addressing unsafe conditions in Bell Textron Inc. Model 204B, 205A, 205A-1, 205B, 210, and 212 helicopters. It targets defective main rotor hub strap pins, part number 204-012-104-005 with serial number prefix "FNFS", which have been linked to a fatal accident due to pin failure causing rotor detachment.

What changed

This directive supersedes AD 2021-15-51 by expanding the applicability to include Model 210 helicopters in addition to the previously affected models. It continues the requirement to remove the defective pins from service and prohibits their installation on any affected helicopter models.

Why it matters

This AD is critical for aviation safety as failure of the specified pins can lead to main rotor blade detachment and loss of helicopter control. Operators, maintenance organizations, and compliance teams must address this to prevent accidents and ensure regulatory compliance.
