Model OH–13H (Tomcat Mark 5A, 6B, 6C) Helicopters Federal Aviation Administration, DOT. ACTION: Final rule. AGENCY: SUMMARY: This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron (Bell) Model 47D1, 47G, 47G–2, 47G–2A, 47G–2A–1, 47G–3, 47G–3B, 47G–3B–1, 47G–3B–2, 47G–3B–2A, 47G–4, 47G–4A, 47G–5, 47G–5A and Coastal Helicopters, Inc. Model OH–13H (Tomcat Mark 5A, 6B, 6C) helicopters that have a certain scissors assembly or weld assembly scissors bracket installed. The AD requires, within 60 days, determining and recording the total hours time-inservice (TIS) for each Parts Manufacturer Approval (PMA)produced scissors assembly and weld assembly scissors bracket and establishes a life limit for each affected part. This amendment is prompted by the need to establish a life limit on scissors assemblies and weld assembly scissors brackets produced under PMA No. PQ808SW or installed per Supplemental Type Certificate (STC) No. SH2772SW. The actions specified by this AD are intended to establish a life limit to prevent using a scissors assembly or weld assembly scissors bracket past it’s life limit, which could result in failure of the part and subsequent loss of control of the helicopter. Effective November 21, 2005. You may get the service information identified in this AD from Texas Helicopter Co., Inc., P.O.

FOR FURTHER INFORMATION CONTACT: Marc Belhumeur, Aviation Safety Engineer, FAA, Rotorcraft Directorate, Rotorcraft Certification Office, Fort Worth, Texas 76193–0170, telephone (817) 222–5177, fax (817) 222–5783. SUPPLEMENTARY INFORMATION: A proposal to amend 14 CFR part 39 to include an AD for the specified model helicopters was published in the Federal Register on July 6, 2005 (70 FR 38817). That action proposed to require, within 60 days, determining and recording the total hours TIS for each PMA-produced scissors assembly and weld assembly scissors bracket and establishing a life limit for each affected part. We have reviewed Texas Helicopter Co., Inc. (THC) Service Bulletin No. SB 003, dated December 1, 2002. THC holds STC No. SH2772SW and produces parts under PMA No. PQ808SW. That service bulletin was issued to clarify maintenance inspections and retirement schedules. The service bulletin specifies maintaining Bell Model 47 series and all other helicopters utilizing a 74–150– 259–1M or 74–150–259–3M control installation per STC SH2772SW or 74– 150–117–13M scissors bracket weld assembly as PMA replacement, in accordance with THC Instructions For Continued Airworthiness (ICA), Doc. No. THC 2002–22 Rev. 0, dated December 1, 2002. Those ICAs refer to STC SH2772SW and contain the mandatory retirement times for the scissor assembly and weld assembly scissors bracket in the Airworthiness Limitations section. Interested persons have been afforded an opportunity to participate in the making of this amendment. No comments were received on the proposal or the FAA’s determination of the cost to the public. The FAA has determined that air safety and the public interest require the adoption of the rule as proposed. Based on the manufacturer’s production estimate, this AD will affect 350 helicopters of U.S. registry. Determining and recording the initial hours TIS of each scissors assembly will PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 60205 take 1 hour, replacing a scissors assembly will take 2 hours, and replacing a weld assembly scissors bracket will take 8 hours. The average labor rate is $65 per work hour. Required parts will cost approximately $1,300 for the 2 scissors assemblies required per helicopter and $2,500 for each weld assembly scissors bracket required per helicopter. Based on these figures, the total cost impact of the AD on U.S. operators is $1,580,250, assuming all operators determine and record the hours TIS once, and replace the scissors assembly and weld assembly scissors bracket once. 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 DMS 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.

SUMMARY: This amendment adopts a new airworthiness directive (AD) for 
Bell Helicopter Textron (Bell) Model 47D1, 47G, 47G-2, 47G-2A, 47G-2A-
1, 47G-3, 47G-3B, 47G-3B-1, 47G-3B-2, 47G-3B-2A, 47G-4, 47G-4A, 47G-5, 
47G-5A and Coastal Helicopters, Inc. Model OH-13H (Tomcat Mark 5A, 6B, 
6C) helicopters that have a certain scissors assembly or weld assembly 
scissors bracket installed. The AD requires, within 60 days, 
determining and recording the total hours time-in-service (TIS) for 
each Parts Manufacturer Approval (PMA)-produced scissors assembly and 
weld assembly scissors bracket and establishes a life limit for each 
affected part. This amendment is prompted by the need to establish a 
life limit on scissors assemblies and weld assembly scissors brackets 
produced under PMA No. PQ808SW or installed per Supplemental Type 
Certificate (STC) No. SH2772SW. The actions specified by this AD are 
intended to establish a life limit to prevent using a scissors assembly 
or weld assembly scissors bracket past it's life limit, which could 
result in failure of the part and subsequent loss of control of the 
helicopter.

DATES: Effective November 21, 2005.

5783.

SUPPLEMENTARY INFORMATION: A proposal to amend 14 CFR part 39 to 
include an AD for the specified model helicopters was published in the 
Federal Register on July 6, 2005 (70 FR 38817). That action proposed to 
require, within 60 days, determining and recording the total hours TIS 
for each PMA-produced scissors assembly and weld assembly scissors 
bracket and establishing a life limit for each affected part.
    We have reviewed Texas Helicopter Co., Inc. (THC) Service Bulletin 
No. SB 003, dated December 1, 2002. THC holds STC No. SH2772SW and 
produces parts under PMA No. PQ808SW. That service bulletin was issued 
to clarify maintenance inspections and retirement schedules. The 
service bulletin specifies maintaining Bell Model 47 series and all 
other helicopters utilizing a 74-150-259-1M or 74-150-259-3M control 
installation per STC SH2772SW or 74-150-117-13M scissors bracket weld 
assembly as PMA replacement, in accordance with THC Instructions For 
Continued Airworthiness (ICA), Doc. No. THC 2002-22 Rev. 0, dated 
December 1, 2002. Those ICAs refer to STC SH2772SW and contain the 
mandatory retirement times for the scissor assembly and weld assembly 
scissors bracket in the Airworthiness Limitations section.
    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were received on the 
proposal or the FAA's determination of the cost to the public. The FAA 
has determined that air safety and the public interest require the 
adoption of the rule as proposed.
    Based on the manufacturer's production estimate, this AD will 
affect 350 helicopters of U.S. registry. Determining and recording the 
initial hours TIS of each scissors assembly will take 1 hour, replacing 
a scissors assembly will take 2 hours, and replacing a weld assembly 
scissors bracket will take 8 hours. The average labor rate is $65 per 
work hour. Required parts will cost approximately $1,300 for the 2 
scissors assemblies required per helicopter and $2,500 for each weld 
assembly scissors bracket required per helicopter. Based on these 
figures, the total cost impact of the AD on U.S. operators is 
$1,580,250, assuming all operators determine and record the hours TIS 
once, and replace the scissors assembly and weld assembly scissors 
bracket once.

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 DMS 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.
