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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Bell Textron, Inc. (Type Certificate previously held by 
Bell Helicopter Textron, Inc.) (Bell) Model 204B, 205A, 205A-1, 205B, 
212, 214B, 214B-1, 412, 412CF, and 412EP helicopters. This proposed AD 
was prompted by a report of a shoulder harness seat belt comfort clip 
(comfort clip) interfering with the seat belt inertia reel. This 
proposed AD would require removing comfort clips from service and 
inspecting the seat belt shoulder harness (harness) for a rip or an 
abrasion. The FAA is proposing this AD to address the unsafe condition 
on these products.

DATES: The FAA must receive comments on this proposed AD by May 21, 
2020.

Discussion

    The FAA proposes to adopt a new AD for certain Bell Model 204B, 
205A, 205A-1, 205B, 212, 214B, 214B-1, 412, 412CF, and 412EP 
helicopters. This proposed AD was prompted by a series of service 
bulletins issued by Bell, reporting an issue with certain comfort clips 
part-numbers (P/Ns) D7LZ-6560286-A, D7LZ-6560286-B, and 504636-401, 
which are installed on seat belt assemblies. A design review by 
Leonardo S.p.A Helicopter (formerly Agusta S.p.A., Finmeccanica S.p.A.) 
indicates the use of the affected comfort clips could jeopardize, in 
cases of impact or deceleration, the correct functionality of the seat 
belt or the seat belt inertia reel.
    Bell Model 204B, 205A, 205A-1, 205B, and 212 helicopters were not 
delivered with comfort clips, but due to design similarity, the FAA has 
included them in this proposed AD because owners/operators may install 
the comfort clips post-delivery. Bell consequently reported in its 
service bulletins that it will stop delivering and selling the comfort 
clips.
    The actions of this proposed AD are intended to prevent the seat 
belt from locking, potentially resulting in injury to the occupant 
during an emergency landing.

Related Service Information

    The FAA reviewed Bell Alert Service Bulletin (ASB) 204B-15-70 for 
Model 204B helicopters, Bell ASB 205-15-113 for Model 205A and 205A-1 
helicopters, Bell ASB 205B-15-66 for Model 205B helicopters, Bell ASB 
212-15-156 for Model 212 helicopters, Bell ASB 412-15-170 for Model 412 
and 412EP helicopters, and Bell ASB 412CF-15-60 for Model 412CF 
helicopters, all dated January 20, 2016. The FAA also reviewed Bell ASB 
214-15-76, dated January 11, 2016, for Model 214B and 214B-1 
helicopters. This service information specifies removing the comfort 
clips from all crew and passenger seat belt assemblies.

FAA's Determination

    The FAA is proposing this AD after evaluating all the relevant 
information and determining that the unsafe condition described 
previously is likely to exist or develop in other products of the same 
type design.

Proposed AD Requirements

    This proposed AD would require, within 50 hours time-in-service 
(TIS), removing from service each comfort clip P/Ns D7LZ-6560286-A, 
D7LZ-6560286-B, and 504636-401, from the seat belt assembly and 
inspecting each harness for a rip and an abrasion. If there is a rip or 
abrasion, this proposed AD would require removing the harness from 
service before further flight.
    After the effective date of this AD, this proposed AD would 
prohibit installing any comfort clip P/Ns D7LZ-6560286-A, D7LZ-6560286-
B, or 504636-401 on any helicopter.

Differences Between This Proposed AD and the Service Information

    The service information specifies a compliance time of within 100 
flight hours or no later than February 21, 2016, and does not specify 
inspecting each harness for a rip or an abrasion. This proposed AD 
would require a compliance time of within 50 hours TIS and would 
require inspecting each harness for a rip or an abrasion. The FAA 
determined that including an

[[Page 19114]]

inspection for harness damage is necessary to correct the unsafe 
condition.

Costs of Compliance

    The FAA estimates that this proposed AD would affect 210 
helicopters of U.S. registry. The FAA estimates that operators may 
incur the following costs in order to comply with this AD. Labor costs 
are estimated at $85 per work-hour.
    Removing a comfort clip would take about 0.5 work-hour, for an 
estimated cost of $43 per clip.
    Inspecting a harness would take about 0.25 work-hour, for an 
estimated cost of $21 per harness.
    If required, replacing a harness would take about 1 work-hour and 
parts would cost about $1,050 for an estimated cost of $1,135 per 
harness.

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

    The FAA determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (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.
