FOR FURTHER INFORMATION CONTACT: Sharon Miles, Aviation Safety Engineer, VerDate Aug<31>2005 15:17 Nov 19, 2007 Jkt 214001 FAA, Rotorcraft Directorate, Regulations and Guidance Group, Fort Worth, Texas 76193–0111, telephone (817) 222–5122, fax (817) 222–5961. SUPPLEMENTARY INFORMATION: On September 14, 2007, the FAA issued Emergency AD 2007–19–52 for the specified BHTC model helicopters, which requires replacing each affected part-numbered and serial-numbered blade with an airworthy blade with a serial number not listed in the RBI attachment to the BHTC ASB, listed in the applicability section of this AD. That action was prompted by three incidents in which blade tip weights were slung from the blades during flight causing significant vibration. The failures have occurred on blades being returned to service from RBI, from as short as 12 minutes since repair to as long as 400 hours time-in-service. An investigation indicates that the tip weights were missing the adhesive that should have been applied during the weight-and-balance process on these blades. This condition, if not corrected, could result in loss of a blade tip weight, loss of a blade, and subsequent loss of control of the helicopter. Transport Canada, the airworthiness authority for Canada, notified the FAA that an unsafe condition may exist on these helicopter models. Transport Canada advises of three reports of balance weights departing from the blades during flight. They also advise that they determined in the investigation that the unsafe condition results from the loss of the tip weights and that the failure can occur at any time. BHTC has issued the following Alert Service Bulletins (ASBs): • No. 206–07–116, dated September 11, 2007, for BHTC Model 206 A/B series helicopters; • No. 206L–07–148, dated September 11, 2007, for BHTC Model 206L series helicopters; • No. 222–07–106, Revision A, dated September 13, 2007, for BHTC Model 222 and 222B helicopters; • No. 222U–07–77, Revision A, dated September 13, 2007, for BHTC Model 222U helicopters; • No. 230–07–38, Revision A, dated September 13, 2007, for BHTC Model 230 helicopters; • No. 407–07–81, dated September 11, 2007, for BHTC Model 407 helicopters; • No. 427–07–18, dated September 11, 2007, for BHTC Model 427 helicopters; and • No. 430–07–41, Revision A, dated September 13, 2007, for BHTC Model 430 helicopters. PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 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 screws during the weight and balance process. Transport Canada classified the ASBs as mandatory and issued AD No. CF–2007–21, dated September 13, 2007, to ensure the continued airworthiness of these helicopters in Canada. Paragraph (a) of the AD states that you must replace any affected blade with an airworthy blade with a serial number not listed in the applicability section of this AD. The serial numbers are not directly listed in the applicability section of this AD. The ASBs for the various model helicopters are listed in the applicability section. The affected part and serial numbers are listed in the RBI attachment to each of the BHTC ASBs listed in the applicability section of this AD. We have clarified that language in the AD and have determined that this change will neither increase the economic burden on any operator nor increase the scope of the AD. These helicopter models are manufactured in Canada and are type certificated for operation in the United States under the provisions of 14 CFR 21.29 and the applicable bilateral agreement. Pursuant to the applicable bilateral agreement, Transport Canada has kept the FAA informed of the situation described above. The FAA has examined the findings of Transport Canada, reviewed all available information, and determined that AD action is necessary for products of these type designs that are certificated for operation in the United States. Since the unsafe condition described is likely to exist or develop on other BHTC model helicopters of these same type designs, the FAA issued Emergency AD 2007–19–52 to prevent loss of a blade tip weight, loss of a blade, and subsequent loss of control of the helicopter. The AD requires before further flight, removing and replacing each affected blade with an airworthy blade. The actions must be accomplished for the blade part numbers with serial numbers listed in the RBI attachment to the ASBs described previously. The short compliance time involved is required because the previously described critical unsafe condition can adversely affect the structural integrity and controllability of the helicopter. Therefore, removing and replacing each affected blade with an airworthy blade is required before further flight, and this AD must be issued immediately. Since it was found that immediate corrective action was required, notice E:\FR\FM\20NOR1.SGM 20NOR1 Federal Register / Vol. 72, No. 223 / Tuesday, November 20, 2007 / Rules and Regulations and opportunity for prior public comment thereon were impracticable and contrary to the public interest, and good cause existed to make the AD effective immediately by individual letters issued on September 14, 2007, to all known U.S. owners and operators of the specified BHTC model helicopters. These conditions still exist, and the AD is hereby published in the Federal Register as an amendment to 14 CFR 39.13 to make it effective to all persons. The FAA estimates that this AD will affect 3741 helicopters of U.S. registry, and it will take about 2 hours to determine if a blade is affected per helicopter at an average labor rate of $80 per work hour. The ASB contains a warranty statement that owners or operators of Bell 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 $589,560, assuming all shipping, inspection, and repair costs are paid by RBI or Bell. Comments Invited This AD is a final rule that involves requirements that affect flight safety and was not preceded by notice and an opportunity for public comment; however, we invite you to submit any written data, views, or arguments regarding this AD. Send your comments to an address listed under ADDRESSES. Include ‘‘Docket No. FAA–2007–0179; Directorate Identifier 2007–SW–36–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the AD. We will consider all comments received by the closing date and may amend the AD in light of those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact with FAA personnel concerning this AD. Using the search function of the docket web site, you can find and read the comments to any of our dockets, including the name of the individual who sent the comment. You may review the DOT’s complete Privacy Act Statement in the Federal Register published on April 11, 2000 (65 FR 19477–78). 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 products identified in this rulemaking action. Regulatory Findings We have 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 the regulation: 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. See the AD docket to examine the economic evaluation. List of Subjects in 14 CFR Part 39 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.

SUPPLEMENTARY INFORMATION: On September 14, 2007, the FAA issued Emergency AD 2007–19–53 for the specified model helicopters, which requires replacing each affected partnumbered and serial-numbered blade with an airworthy blade with a serial number not listed in the applicability of this AD. That action was prompted by three incidents in which blade tip weights were slung from the blades during flight causing significant vibration. The failures have occurred on blades being returned to service from Rotor Blades, Inc. (RBI), from as short as 12 minutes since repair to as long as 400 hours time-in-service. An investigation indicates that the tip weights were missing the adhesive that should have been applied during the weight-andbalance process on these blades. This condition, if not corrected, could result in loss of a blade tip weight, loss of a blade, and subsequent loss of control of the helicopter. BHTI has issued the following Alert Service Bulletins (ASB): • No. 204–07–61 for BHTI Model 204 helicopters, • No. 205–07–95 for BHTI Model 205 helicopters, • No. 205B–07–46 for BHTI Model 205B helicopters, • No. 212–07–125 for BHTI Model 212 helicopters, and • No. 412–07–123 for BHTI Model 412 helicopters. All the ASBs are dated September 11, 2007, and contain a letter from RBI indicating certain blades processed by RBI may be missing the adhesive applied to the tip weight screws during the weight and balance process. Emergency AD 2007–19–53 had the Model 230 helicopters incorrectly linked to ASB No. 412–07–123; that ASB is for Model 412 helicopters. We have made that correction in this AD and determined that this change will neither increase the economic burden on any operator nor increase the scope of the AD. Since the unsafe condition described is likely to exist or develop on other specified BHTI model helicopters of these same type designs, the FAA issued Emergency AD 2007–19–53 to prevent loss of a blade tip weight, loss of a blade, and subsequent loss of control of the helicopter. The AD requires replacing each affected blade with an airworthy blade. The short compliance E:\FR\FM\20NOR1.SGM 20NOR1

rotor blade (blade) with an airworthy blade with a serial number not
listed in the Rotor Blades, Inc. (RBI), attachment to the BHTC Alert
Service Bulletin (ASB), listed in the applicability section of this AD.
This amendment is prompted by three incidents in which blade tip
weights were slung from blades during flight causing significant
vibration. The actions specified are intended to prevent loss of a
blade tip weight, loss of a blade, and subsequent loss of control of
the helicopter.

DATES: Effective December 5, 2007, to all persons except those persons
to whom it was made immediately effective by Emergency AD 2007-19-52,
issued on September 14, 2007, which contained the requirements of this
amendment.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of December 5, 2007.
Comments for inclusion in the Rules Docket must be received on or

SUPPLEMENTARY INFORMATION: On September 14, 2007, the FAA issued
Emergency AD 2007-19-52 for the specified BHTC model helicopters, which
requires replacing each affected part-numbered and serial-numbered
blade with an airworthy blade with a serial number not listed in the
RBI attachment to the BHTC ASB, listed in the applicability section of
this AD. That action was prompted by three incidents in which blade tip
weights were slung from the blades during flight causing significant
vibration. The failures have occurred on blades being returned to
service from RBI, from as short as 12 minutes since repair to as long
as 400 hours time-in-service. An investigation indicates that the tip
weights were missing the adhesive that should have been applied during
the weight-and-balance process on these blades. This condition, if not
corrected, could result in loss of a blade tip weight, loss of a blade,
and subsequent loss of control of the helicopter.
Transport Canada, the airworthiness authority for Canada, notified
the FAA that an unsafe condition may exist on these helicopter models.
Transport Canada advises of three reports of balance weights departing
from the blades during flight. They also advise that they determined in
the investigation that the unsafe condition results from the loss of
the tip weights and that the failure can occur at any time.
BHTC has issued the following Alert Service Bulletins (ASBs):
No. 206-07-116, dated September 11, 2007, for BHTC Model
206 A/B series helicopters;
No. 206L-07-148, dated September 11, 2007, for BHTC Model
206L series helicopters;
No. 222-07-106, Revision A, dated September 13, 2007, for
BHTC Model 222 and 222B helicopters;
No. 222U-07-77, Revision A, dated September 13, 2007, for
BHTC Model 222U helicopters;
No. 230-07-38, Revision A, dated September 13, 2007, for
BHTC Model 230 helicopters;
No. 407-07-81, dated September 11, 2007, for BHTC Model
407 helicopters;
No. 427-07-18, dated September 11, 2007, for BHTC Model
427 helicopters; and
No. 430-07-41, Revision A, dated September 13, 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 screws during the weight and balance process. Transport Canada
classified the ASBs as mandatory and issued AD No. CF-2007-21, dated
September 13, 2007, to ensure the continued airworthiness of these
helicopters in Canada.
Paragraph (a) of the AD states that you must replace any affected
blade with an airworthy blade with a serial number not listed in the
applicability section of this AD. The serial numbers are not directly
listed in the applicability section of this AD. The ASBs for the
various model helicopters are listed in the applicability section. The
affected part and serial numbers are listed in the RBI attachment to
each of the BHTC ASBs listed in the applicability section of this AD.
We have clarified that language in the AD and have determined that this
change will neither increase the economic burden on any operator nor
increase the scope of the AD.
These helicopter models are manufactured in Canada and are type
certificated for operation in the United States under the provisions of
14 CFR 21.29 and the applicable bilateral agreement. Pursuant to the
applicable bilateral agreement, Transport Canada has kept the FAA
informed of the situation described above. The FAA has examined the
findings of Transport Canada, reviewed all available information, and
determined that AD action is necessary for products of these type
designs that are certificated for operation in the United States.
Since the unsafe condition described is likely to exist or develop
on other BHTC model helicopters of these same type designs, the FAA
issued Emergency AD 2007-19-52 to prevent loss of a blade tip weight,
loss of a blade, and subsequent loss of control of the helicopter. The
AD requires before further flight, removing and replacing each affected
blade with an airworthy blade. The actions must be accomplished for the
blade part numbers with serial numbers listed in the RBI attachment to
the ASBs described previously. The short compliance time involved is
required because the previously described critical unsafe condition can
adversely affect the structural integrity and controllability of the
helicopter. Therefore, removing and replacing each affected blade with
an airworthy blade is required before further flight, and this AD must
be issued immediately.
Since it was found that immediate corrective action was required,
notice

[[Page 65223]]

and opportunity for prior public comment thereon were impracticable and
contrary to the public interest, and good cause existed to make the AD
effective immediately by individual letters issued on September 14,
2007, to all known U.S. owners and operators of the specified BHTC
model helicopters. These conditions still exist, and the AD is hereby
published in the Federal Register as an amendment to 14 CFR 39.13 to
make it effective to all persons.
The FAA estimates that this AD will affect 3741 helicopters of U.S.
registry, and it will take about 2 hours to determine if a blade is
affected per helicopter at an average labor rate of $80 per work hour.
The ASB contains a warranty statement that owners or operators of Bell
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 $589,560, assuming all
shipping, inspection, and repair costs are paid by RBI or Bell.

Comments Invited

This AD is a final rule that involves requirements that affect
flight safety and was not preceded by notice and an opportunity for
public comment; however, we invite you to submit any written data,
views, or arguments regarding this AD. Send your comments to an address
listed under ADDRESSES. Include ``Docket No. FAA-2007-0179; Directorate
Identifier 2007-SW-36-AD'' at the beginning of your comments. We
specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of the AD. We will consider all
comments received by the closing date and may amend the AD in light of
those comments.
We will post all comments we receive, without change, to https://
www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact
with FAA personnel concerning this AD. Using the search function of the
docket web site, you can find and read the comments to any of our
dockets, including the name of the individual who sent the comment. You
may review the DOT's complete Privacy Act Statement in the Federal
Register published on April 11, 2000 (65 FR 19477-78).

Regulatory Findings

We have 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 the regulation:
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. See the AD docket to examine the economic evaluation.

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 products identified in this
rulemaking action.
