Airworthiness Directives; Bell Textron Inc. (Type Certificate 
Previously Held by Bell Helicopter Textron Inc.) Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2021-15-

[[Page 1669]]

51, which applied to Bell Textron Inc. (type certificate previously 
held by Bell Helicopter Textron Inc.) Model 204B, 205A, 205A-1, 205B, 
and 212 helicopters. AD 2021-15-51 required removing certain main rotor 
hub strap pins (pins) from service and prohibited installing them on 
any helicopter. Since the FAA issued AD 2021-15-51, it was determined 
that a defective pin could also be installed on Bell Textron Inc. Model 
210 helicopters. This AD continues the required actions in AD 2021-15-
51 and expands the applicability to add Model 210 helicopters. The FAA 
is issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective February 16, 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 a pin P/N 204-012-
104-005 with an S/N prefix ``FNFS'' sheared off during flight, which 
resulted 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 a notice of proposed rulemaking (NPRM) to amend 14 CFR part 
39 to supersede AD 2021-15-51. The NPRM published in the Federal 
Register on November 19, 2021 (86 FR 64832) and it proposed to continue 
to require all of the requirements of AD 2021-15-51 and add Model 210 
helicopters to the applicability.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the costs.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
requires adoption of the AD as proposed. Accordingly, the FAA is 
issuing this AD to address the unsafe condition on these products. 
Except for minor editorial changes, this AD is adopted as proposed in 
the NPRM.

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 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.

Interim Action

    The FAA considers this AD to be an interim action. If final action 
is later identified, the FAA might consider further rulemaking.

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.
    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.
    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

[[Page 1670]]

develop on products identified in this rulemaking action.

Regulatory Findings

    The FAA has determined that 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,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
