Airworthiness Directives; Bell Helicopter Textron Canada Limited
Model 206A, 206B, 206L, 206L-1, 206L-3, 206L-4, 222, 222B, 222U, 230,
407, 427, and 430 Helicopters

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a superseding airworthiness directive (AD) for
the specified Bell Helicopter Textron Canada Limited (BHTC) Model 206A,
206B, 206L, 206L-1, 206L-3, 206L-4, 222, 222B, 222U, 230, 407, 427, and
430 helicopters. That AD currently requires replacing each affected
tail rotor blade (blade) with an airworthy blade that has a serial
number not listed in the Rotor Blades, Inc. (RBI) document that is
attached to each of the Bell Helicopter Textron Alert Service Bulletins
(ASBs) listed in the applicability section of the AD. That AD results
from mandatory continuing airworthiness information (MCAI) issued by
the aviation authority of Canada. The MCAI states that there have been
three reports of blade tip weights departing from the blade during
flight. Since issuing that AD, BHTC has issued revised service
information to correct part numbers and serial numbers listed in the
RBI document that is attached to each BHTC ASB and to add additional
part-numbered and serial-numbered blades to the list. The actions of
this AD are intended to prevent loss of a blade tip weight, loss of a
blade, and subsequent loss of control of the helicopter.

DATES: This AD becomes effective on April 24, 2009.
The incorporation by reference of certain publications is approved
by the Director of the Federal Register as of April 24, 2009.
We must receive comments on this AD by June 8, 2009.

SUPPLEMENTARY INFORMATION:

Discussion

On October 31, 2007, the FAA issued AD 2007-19-52, Amendment 39-
15264 (72 FR 65221, November 20, 2007), to publish Emergency AD 2007-
19-52, which made the AD effective to all persons except those to whom
it was made immediately effective on September 14, 2007. That AD
requires, before further flight, removing and replacing each affected
blade with an airworthy blade. That action was prompted by three
reports of blade tip weights being slung from the blades during
flights, causing significant vibration.
Since issuing that AD, BHTC has revised the ASBs based on revisions
to the RBI documents that are attached to the ASBs to add blade serial
numbers to the applicability. Also, the ASBs have been revised to add
clarification to the applicability by adding specific part number dash
numbers.
Transport Canada, which is the aviation authority for Canada, has
issued Transport Canada AD No. CF-2007-21, dated September 13, 2007, to
correct an unsafe condition for the BHTC Model 206A, 206B, 206L, 206L-
1, 206L-3, 206L-4, 222, 222B, 222U, 230, 407, 427, and 430 helicopters.
The MCAI states that there have been three reports of blade tip weights
departing from the blade during flight. The actions are intended to
prevent loss of a blade tip weight, loss of a blade, and subsequent
loss of control of the helicopter. Although the BHTC ASBs have been
revised since they were referenced in our AD 2007-19-52, the Transport
Canada AD has not been revised.
You may obtain further information by examining the MCAI and any
related service information in the AD docket.

Related Service Information

BHTC has issued the following:
ASB No. 206-07-116, Revision A, dated September 19, 2007,
for BHTC Model 206 A/B series helicopters;
ASB No. 206L-07-148, Revision A, dated September 19, 2007,
for BHTC Model 206L series helicopters;
ASB No. 222-07-106, Revision C, dated September 20, 2007,
for BHTC Model 222 and 222B helicopters;
ASB No. 222U-07-77, Revision C, dated September 20, 2007,
for BHTC Model 222U helicopters;
ASB No. 230-07-38, Revision C, dated September 20, 2007,
for BHTC Model 230 helicopters;
ASB No. 407-07-81, Revision A, dated September 19, 2007,
for BHTC Model 407 helicopters;
ASB No. 427-07-18, Revision A, dated September 19, 2007,
for BHTC Model 427 helicopters; and
ASB No. 430-07-41, Revision C, dated September 20, 2007,
for BHTC Model 430 helicopters.
All of the ASBs contain a letter from RBI indicating that certain
blades processed by RBI may be missing the adhesive applied to the tip
weight screw during the weight and balance process. Since the issuance
of AD 2007-19-52, some ASBs have been revised to include additional
blade part numbers and serial numbers that require inspection, as well
as to clarify the part number applicability by adding specific part
number ``dash numbers.'' Additionally, the ASBs' revisions specify
marking the blade with an ``L'' once inspection determines that the
blade is airworthy. The actions described in the MCAI are intended to
correct the same unsafe condition as that identified in the service
information.

[[Page 16113]]

FAA's Evaluation and Unsafe Condition Determination

These helicopters have been approved by the aviation authority of
Canada and are approved for operation in the United States. Pursuant to
our bilateral agreement with Canada, they have notified us of the
unsafe condition described in the MCAI. We are issuing this AD because
we evaluated all information provided by Transport Canada and
determined the unsafe condition exists and is likely to exist or
develop on other helicopters of these same type designs.

Differences Between This AD and the MCAI

The actions required by this AD only apply to those blades listed
in the RBI document that is attached to the ASBs listed in paragraph
(c). The MCAI allows use of those ASBs, or ``later revisions approved
by Chief, Continuing Airworthiness, Transport Canada.''

Costs of Compliance

We estimate that this AD will affect about 3,741 helicopters of
U.S. registry. We also estimate that it will take about 2 work-hours
per helicopter to determine if an affected blade is installed. The
average labor rate is $80 per work-hour. The ASB contains a warranty
statement that owners or operators of BHTC helicopters who comply with
the instructions in the ASB will be eligible to return defective blades
identified by serial number in the compliance section to their nearest
RBI facility for inspection and repair at no cost. Based on these
figures, we estimate the total cost impact of the AD on U.S. operators
to be $598,560, assuming all shipping, inspection, and repair costs are
paid by RBI or BHTC.

FAA's Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of
this AD. We find that the risk to the flying public justifies waiving
notice and comment prior to adoption of this rule because loss of a
blade tip weight during flight can adversely affect the controllability
and structural integrity of the helicopter. Also, determining if an
affected blade is installed and replacing any affected blade before
further flight is required. Therefore, we have determined that notice
and opportunity for public comment before issuing this AD are
impracticable and that good cause exists for making this amendment
effective in fewer than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight
safety, and we did not precede it by notice and opportunity for public
comment. However, we invite you to send us any written data, views, or
arguments concerning this AD. Send your comments to an address listed
under the ADDRESSES section of this AD. Include ``Docket No. FAA-2009-
0301; Directorate Identifier 2008-SW-69-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of this AD. We will
consider all comments received by the closing date and may amend this
AD because of those comments.
We will post all comments we receive, without change, to http://
www.regulations.gov including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.

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.
We are 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 helicopters identified in this
rulemaking action.

Regulatory Findings

We 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.
Therefore, I certify this AD:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979); 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.
We prepared an economic evaluation of the estimated costs to comply
with this AD and placed it in the AD docket.

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

Reason

(d) The mandatory continuing airworthiness information (MCAI)
states that there have been three reports of blade tip weights
departing from the blade during flight. This AD corrects part
numbers and serial numbers of blades, and adds additional blades to
the previous AD listing, based on revised ASBs issued by Bell
Helicopter Textron Canada Limited. The actions required by this AD
are intended to prevent loss of a blade tip weight, loss of a blade,
and subsequent loss of control of the helicopter.

Actions and Compliance

(e) Before further flight, unless already accomplished, replace
any affected blade with an airworthy blade. An airworthy blade is
one that has a part number and a serial number that is not listed in
the RBI document that is attached to each ASB listed in the
Applicability section of this AD.

Differences Between This AD and the MCAI AD

(f) The actions required by this AD only apply to those blades
listed in the RBI document that is attached to the ASBs listed in
paragraph (c). The MCAI allows use of those ASBs, or ``later
revisions approved by Chief, Continuing Airworthiness, Transport
Canada.''
