Airworthiness Directives; Bell Textron Inc. (Type Certificate Previously Held by Bell Helicopter Textron Inc.) Helicopters
AGENCY:
Federal Aviation Administration (FAA), DOT.
ACTION:
Final rule; request for comments.
SUMMARY:
The FAA is superseding Airworthiness Directive (AD) 2022-02-02 which applied to certain 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 main rotor hub strap pin (pin) installed. AD 2022-02-02 required removing certain outboard pins from service and prohibited installing them on any helicopter. This AD expands the applicability to all affected pins, regardless if they are outboard or inboard. This AD also requires inspecting the removed pin for any deformation and if it is deformed, removing the mating strap fitting (fitting) from service. This AD was prompted by the discovery that AD 2022-02-02 inadvertently limited its applicability to only outboard pins when, in fact, all pins are subject to the unsafe condition and the determination that a deformed pin may have damaged the fitting. The FAA is issuing this AD to address the unsafe condition on these products.
DATES:
This AD is effective March 16, 2022.
The FAA must receive any comments on this AD by April 28, 2022.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued Emergency AD 2021-15-51 on July 6, 2021, and it published as a Final rule; request for comments on August 9, 2021 as Amendment 39-21678 (86 FR 43406) (AD 2021-15-51). AD 2021-15-51 applied to Bell Textron Inc. Model 204B, 205A, 205A-1, 205B, and 212 helicopters with a pin part number (P/N) 204-012-104-005 with a serial number (S/N) prefix "FNFS" installed. AD 2021-15-51 was prompted by a fatal accident of a Model 212 helicopter in which the affected pin sheared off during flight, resulting in the main rotor blade and the main rotor head detaching from the helicopter. The pin had accumulated only 20 total hours time-in-service (TIS). An inspection of a different Model 212 helicopter revealed that another pin installed, and made by the same manufacturer and with the same S/N prefix, was deformed; this pin had accumulated only 29 total hours TIS. Because an affected pin could also be installed on other helicopters, AD 2021-15-51 also applied to Model 204B, 205A, 205A-1, and 205B helicopters. Failure of a pin could result in the main rotor blade detaching from the helicopter and subsequent loss of control of the helicopter.
After AD 2021-15-51 was issued, it was determined that an affected pin could also be installed on Model 210 helicopters. Therefore, the FAA issued superseding AD 2022-02-02 (87 FR 1668, January 12, 2022) (AD 2022-02-02) which retained all of the requirements in AD 2021-15-51 and added Model 210 helicopters to the applicability. However, as published, the AD number in the regulatory text was incorrectly specified as FAA-2021-1003; the correct AD number was 2022-02-02. The FAA subsequently issued corrected AD 2022-02-02 (87 FR 7368, February 9, 2022) to correct the AD number.
Actions Since AD 2022-02-02 Was Issued
[top] Since the FAA issued AD 2022-02-02, it was discovered that the word "outboard" was inadvertently included in that AD's applicability, resulting in the possibility that corrective actions for the inboard pin may not be accomplished. Additionally, the FAA determined, after further review of the related service information, that inspecting the affected pin for any deformity and removing the fitting P/N 212-010-103-ALL or 204-012-103-ALL from service is required to address the unsafe condition. The FAA is issuing this AD to address the unsafe condition on these products.
FAA's Determination
The FAA is issuing this AD because the agency determined the unsafe condition described previously is likely to exist or develop in other products of the same type designs.
Related Service Information
The FAA reviewed Bell Alert Service Bulletins (ASBs), each Revision A and dated July 22, 2021:
• ASB 204B-21-74 for Model 204B helicopters, S/Ns 2001 through 2070 and 2196 through 2199;
• ASB 205-21-117 for Model 205A and 205A-1 helicopters, S/Ns 30001 through 30065, 30067 through 30165, 30167 through 30187, 30189 through 30296, and 30298 through 30332;
• ASB 205B-21-71 for Model 205B helicopters, S/Ns 30066, 30166, 30188, and 30297;
• ASB 210-21-14 for all Model 210 helicopters, and
• ASB 212-21-165 for Model 212 helicopters, S/Ns 30501 through 30999, 31101 through 31311, 32101 through 32142, and 35001 through 35103.
The ASBs specify removing all P/N 204-012-104-005 pins with an S/N prefix "FNFS" before further flight. The ASBs also specify inspecting removed pins for deformation and scrapping the fitting, P/N 212-010-103-ALL or 204-012-103-ALL, if the pin is deformed. The ASBs also specify that, although the investigation is still in progress, removing these pins from service is required. The ASBs state that these pins may not have been manufactured in accordance with the engineering design requirements and may therefore shear as a result of this nonconformance.
AD Requirements
This AD requires, before further flight, removing from service each pin P/N 204-012-104-005 with an S/N prefix "FNFS" and inspecting it for any deformation. If there is any deformation, this AD also requires removing the fitting from service before further flight. Finally, this AD prohibits installing the affected pin on any helicopter as of the effective date of this AD.
Interim Action
The FAA considers this AD to be an interim action. If final action is later identified, the FAA might consider further rulemaking.
Justification for Immediate Adoption and Determination of the Effective Date
Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 U.S.C. 551 et seq. ) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for "good cause," finds that those procedures are "impracticable, unnecessary, or contrary to the public interest." Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause.
An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies foregoing notice and comment prior to adoption of this rule because an affected pin was involved in a fatal accident in which the pin sheared off during flight, resulting in the main rotor blade and the main rotor head detaching from the helicopter. That pin had accumulated only 20 total hours TIS. An additional investigation revealed that another pin installed on a different helicopter and made by the same manufacturer and with the same S/N prefix was deformed. This pin had accumulated only 29 total hours TIS. The wording in AD 2022-02-02 could have caused an inboard pin with the same part number and S/N prefix, which is subject to the same unsafe condition, to be left in service. Failure of an affected pin could occur at any time without any previous indication, which could result in the failure of parts critical to the control of the helicopter. Thus, an urgent unsafe condition exists and corrective actions must be accomplished before further flight.
Accordingly, notice and opportunity for prior public comment are impracticable and contrary to the public interest pursuant to 5 U.S.C. 553(b)(3)(B). In addition, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days, for the same reasons the FAA found good cause to forgo notice and comment.
Comments Invited
The FAA invites you to send any written data, views, or arguments about this final rule. Send your comments to an address listed under ADDRESSES . Include "Docket No. FAA-2022-0157 and Project Identifier AD 2022-00193-R" at the beginning of your comments. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. The FAA will consider all comments received by the closing date and may amend this final rule because of those comments.
Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, to https://www.regulations.gov, including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact received about this final rule.
Confidential Business Information
CBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this AD contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this AD, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI as "PROPIN." The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this AD. Submissions containing CBI should be sent to Kuethe Harmon, Safety Management Program Manager, Certification & Program Management Section, DSCO Branch, Compliance & Airworthiness Division, FAA, 10101 Hillwood Pkwy., Fort Worth, TX 76177. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking.
Regulatory Flexibility Act
The requirements of the Regulatory Flexibility Act (RFA) do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without prior notice and comment, RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects 155 helicopters of U.S. Registry. Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates the following costs to comply with this AD.
[top] Replacing up to four pins takes about 20 work-hours and parts cost about $1,756 for four pins for an estimated cost of up to $3,456 per helicopter, and up to $535,680 for the U.S. fleet.
Replacing up to 4 fittings takes about 2 work-hours and parts cost about $14,400 for an estimated cost of up to $14,570 per helicopter, and up to $2,258,350 for the U.S. fleet.
The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency's authority.
The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701, General requirements. Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.
Regulatory Findings
This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a "significant regulatory action" under Executive Order 12866, and
(2) Will not affect intrastate aviation in Alaska.
