That AD applies to Bell Textron Inc. (type certificate previously held by Bell Helicopter Textron Inc.) Model 204B, 205A, 205A-1, 205B, 210, and 212 helicopters with a certain outboard main rotor hub strap pin (pin) installed. As published, the AD number specified in the regulatory text is incorrect. This document corrects that error. In all other respects, the original document remains the same. ## The airworthiness directive 1. The authority citation for part 39 continues to read as follows: 2. The FAA amends § 39.13 by: a. Removing Airworthiness Directive 2021-15-51, Amendment 39-21678 (86 FR 43406, August 9, 2021); and b. Adding the following new airworthiness directive: 2022-02-02 Bell Textron Inc. (Type Certificate Previously Held by Bell Helicopter Textron Inc.): Amendment 39-21899; Docket No. FAA-2021-1003; Project Identifier AD-2021-01141-R. ### (a) Effective Date This airworthiness directive (AD) is effective February 16, 2022. ### (b) Affected ADs This AD replaces AD 2021-15-51, Amendment 39-21678 (86 FR 43406, August 9, 2021) (AD 2021-15-51). ### (c) Applicability This AD applies to Bell Textron Inc. (type certificate previously held by Bell Helicopter Textron Inc.) Model 204B, 205A, 205A-1, 205B, 210, and 212 helicopters, certificated in any category, with an outboard main rotor hub strap pin (pin) part number 204-012-104-005 with a serial number prefix “FNFS” installed. ### (d) Subject Joint Aircraft System Component (JASC) Code: 6200, Main Rotor System. ### (e) Unsafe Condition This AD was prompted by a fatal accident in which a pin sheared off during flight, which resulted in the main rotor blade and the main rotor head detaching from the helicopter. The FAA is issuing this AD to address this unsafe condition and prevent loss of control of the helicopter. ### (f) Compliance Comply with this AD within the compliance times specified, unless already done. ### (g) Required Actions (1) For Model 204B, 205A, 205A-1, 205B, and 212 helicopters: (i) Before further flight from August 24, 2021 (the effective date of AD 2021-15-51), remove from service any pin that is identified in paragraph (c) of this AD. (ii) After August 24, 2021 (the effective date of AD 2021-15-51), do not install any pin that is identified in paragraph (c) of this AD on any helicopter. (2) For Model 210 helicopters: (i) Before further flight after the effective date of this AD, remove from service any pin that is identified in paragraph (c) of this AD. (ii) As of the effective date of this AD, do not install any pin that is identified in paragraph (c) of this AD on any helicopter. ### (h) Special Flight Permits Special flight permits are prohibited. ### (i) Alternative Methods of Compliance (AMOCs) (1) The Manager, DSCO Branch, Compliance & Airworthiness Division, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the manager of the DSCO Branch, send it to the attention of the person identified in paragraph (j) of this AD. Information may be emailed to: 9-ASW-190-COS@faa.gov.

The incorrectly specified AD number was FAA-2021-1003; the correct AD number is 2022-02-02. ### Correction of Publication This document corrects an error and correctly adds the AD as an amendment to 14 CFR 39.13. Although no other part of the preamble or regulatory information has been corrected, the FAA is publishing the entire rule in the Federal Register. The effective date of this AD remains February 16, 2022. Since this action only corrects the AD number, it has no adverse economic impact and imposes no additional burden on any person. Therefore, the FAA has determined that notice and public comment procedures are unnecessary. ### Adoption of the Correction Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: ## Affected data sheets (2) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS H1SW](https://openairdocs.org/tcds/H1SW): Bell Textron Inc.; names 5 of 5 models: 205A, 205B, 204B, 205A-1, 210 - [TCDS H4SW](https://openairdocs.org/tcds/H4SW): Bell Textron Inc.; names 1 of 4 models: 212 ## Registered aircraft it may apply to (OpenAirDocs) Matched by airframe and engine model; the AD's applicability may narrow it by serial number, part number or equipment. - Aircraft: 129 (129 by airframe model, 0 by engine model) - Makers: Bell 118, Bell Helicopter Textron 9, Bell/Southwest Florida Aviatio 2 Models with the most aircraft: - [Bell 205A-1](https://openairdocs.org/model/bell-205a-1): 56 aircraft (airframe model) - [Bell 212](https://openairdocs.org/model/bell-212): 54 aircraft (airframe model) - [Bell 204-B](https://openairdocs.org/model/bell-204-b): 7 aircraft (airframe model) - [Bell Helicopter Textron 212](https://openairdocs.org/model/bell-helicopter-textron-212): 5 aircraft (airframe model) - [Bell Helicopter Textron 210](https://openairdocs.org/model/bell-helicopter-textron-210): 3 aircraft (airframe model) - [Bell/Southwest Florida Aviatio 205 A1](https://openairdocs.org/model/bell-southwest-florida-aviatio-205-a1): 2 aircraft (airframe model) - [Bell 205B](https://openairdocs.org/model/bell-205b): 1 aircraft (airframe model) - [Bell Helicopter Textron 205A-1](https://openairdocs.org/model/bell-helicopter-textron-205a-1): 1 aircraft (airframe model) All 8 models: https://openairdocs.org/ad/2022-02-02/models.md Every aircraft: https://openairdocs.org/ad/2022-02-02/aircraft.md ## Related documents - [AD 2022-06-03](https://openairdocs.org/ad/2022-06-03): Main Rotor System · Bell Textron 204B, 205A, 205A-1 and 3 more.
