Airworthiness Directives; Bell Helicopter Textron Canada Model 430 Helicopters, 29-32 [E7-25389]

Download as PDF Federal Register / Vol. 73, No. 1 / Wednesday, January 2, 2008 / Rules and Regulations operate and maintain the aircraft in conformance with regulations and with requirements for operation and maintenance of the product. • AIRBUS Comment (d): Airbus noted that the special conditions consider only interference between the Passenger Information and Entertainment Domain (PIED) and the Airline Information Domain or Aircraft Control Domain. It notes there is no requirement for protecting the Aircraft Control Domain from the Airline Information Domain, if this one is considered less trusted than the Aircraft Control Domain. As an example, it said that the Airline Information Domain could implement portable electronic flight bags. FAA Response: These special conditions address only the interfaces between the passenger domain (PIED) and other aircraft systems and networks. Other interfaces and accesses are addressed by current regulations and policy, and by another proposed special conditions. • AIRBUS Comment (e): Airbus said that, depending on the meaning of ‘‘unauthorized external access,’’ these special conditions may be redundant to proposed special conditions 25–07–02– SC (see comment ‘‘b’’ about 25–07–02– SC). FAA Response: These special conditions are not redundant. The passenger PIED and its security implementation are part of the airplane model and type design, and are not considered ‘‘external’’ to the aircraft. In reviewing the Boeing-proposed 787 network architecture and design during development of these special conditions, we determined the need for two separate special conditions. To ensure appropriate security protection of the aircraft and its systems, one special condition was needed for access from the passenger domain, and one for access from sources external to the airplane. • AIRBUS proposed text revision: Airbus proposed the following revised wording for these special conditions. pwalker on PROD1PC71 with RULES The applicant shall ensure that security threats from all points within the Passenger Information and Entertainment Domain, are identified and risk mitigation strategies are implemented to protect the Aircraft Control Domain and Airline Information Services Domain from adverse impacts reducing the aircraft safety. FAA Response: As noted previously, the purpose of these special conditions is to ensure security protection from all inadvertent or malicious changes to, and all adverse impacts to, airplane systems, networks, hardware, software, and data from accesses through the passenger domain. We do not believe the VerDate Aug<31>2005 19:41 Dec 31, 2007 Jkt 214001 commenter’s proposal is specific enough to achieve this purpose, and we will retain the current wording. Applicability As discussed above, these special conditions are applicable to the 787. Should Boeing apply at a later date for a change to the type certificate to include another model on the same type certificate incorporating the same novel or unusual design features, these special conditions would apply to that model as well. Conclusion This action affects only certain novel or unusual design features of the 787. It is not a rule of general applicability.

ACTION: Final rule. AGENCY: PO 00000 Frm 00029 Fmt 4700 Sfmt 4700 29 SUMMARY: This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 430 helicopters that requires replacing a certain servo actuator-toactuator support attachment bolt (bolt) with an airworthy bolt. This action also requires establishing a retirement life for certain bolts and recording the retirement life on a component history card or equivalent record. This amendment is prompted by further evaluation of certain fatigue-critical parts, resulting in establishing a life limit of 5,000 hours for the affected bolts. The actions specified by this AD are intended to prevent fatigue failure of the bolt and subsequent loss of control of the helicopter. DATES: Effective February 6, 2008. ADDRESSES: You may get the service information identified in this AD from Bell Helicopter Textron Canada, 12,800 Rue de l’Avenir, Mirabel, Quebec J7J1R4, telephone (450) 437–2862 or (800) 363–8023, fax (450) 433–0272. Examining the Docket: You may examine the docket that contains this AD, any comments, and other information on the Internet at https:// www.regulations.gov or at the Docket Operations office, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC.

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 16, 2007 (72 FR 38797). That action proposed to require replacing a certain bolt with an airworthy bolt. That action also proposed establishing a retirement life for certain bolts and recording the retirement life on a component history card or equivalent record. Transport Canada, the airworthiness authority for Canada, notified the FAA that an unsafe condition may exist on BHTC Model 430 helicopters, serial numbers 49001 through 49106. Transport Canada advises of the need to establish a new airworthiness life limitation of 5,000 hours for the three servo actuator support attachment bolts and to replace the three affected bolts. Bell Helicopter Textron has issued Alert Service Bulletin No. 430–05–33, dated February 16, 2005 (ASB). The ASB introduces a retirement life of 5,000 hours for the bolts. The ASB states E:\FR\FM\02JAR1.SGM 02JAR1 30 Federal Register / Vol. 73, No. 1 / Wednesday, January 2, 2008 / Rules and Regulations pwalker on PROD1PC71 with RULES that since these bolts have not been listed in the Helicopter Component Replace record, it is difficult to determine with accuracy the actual number of hours accumulated on fielded bolts. Also, the ASB states that Bell has elected to replace all the fielded bolts, part number (P/N) 50–047C8–31. Transport Canada classified this ASB as mandatory and issued AD No. CF– 2005–09, dated April 14, 2005, to ensure the continued airworthiness of these helicopters in Canada. This helicopter model is manufactured in Canada and is 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 us informed of the situation described above. We have examined the findings of Transport Canada, reviewed all available information, and determined that AD action is necessary for products of this type design that are certificated for operation in the United States. 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 with two changes. We corrected a paragraph under the ADDRESSES section in the preamble to reflect the correct address for getting the service information. Also, we added a Note to the AD stating that there is service information that pertains to the subject of the AD. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD. We estimate that this AD will affect 54 helicopters of U.S. registry, and the required actions will take about 2 work hours per helicopter to replace 3 bolts at an average labor rate of $80 per work VerDate Aug<31>2005 19:41 Dec 31, 2007 Jkt 214001 hour. Required parts will cost about $243 for each bolt. Based on these figures, we estimate the total cost impact of the AD on U.S. operators to be $ $48,006, assuming that the recordkeeping cost would be negligible. 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 List of Subjects in 14 CFR Part 39 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. Air transportation, Aircraft, Aviation safety, Safety. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety.

SUPPLEMENTARY INFORMATION: This rule makes the following corrections to the Export Administration Regulations: Address Changes—Removal of P.O. Box Address for BIS in Washington, DC and Change in Location for BIS San Jose Field Office BIS will no longer accept materials sent to post office box 273 in PO 00000 Frm 00032 Fmt 4700 Sfmt 4700 Washington, DC. In lieu of P.O. Box 273, materials may be sent via courier to Room 2705, 14th Street and Pennsylvania Ave., NW., Washington, DC 20230. To reflect this update, this rule removes references to P.O. Box 273 in parts 730, 740, 743, 748, 752, 754, and 774 and replaces those references with Room 2705, where applicable. Furthermore, this rule updates the address, phone number, and fax number for the San Jose field office in §§ 730.8 (how to proceed and where to get help) and 748.2 (obtaining forms; mailing addresses). Part 740—Reinsertion of Footnotes On March 25, 1996, BIS (then the Bureau of Export Administration, or BXA) published an interim rule (61 FR 12714) which rewrote and reorganized the Export Administration Regulations. The rewrite created part 740 for license exceptions, which included § 740.4 for temporary imports, exports and reexports (TMP) and § 740.7 for gift parcels and humanitarian donations (GFT). On December 4, 1996, BIS published a subsequent revision (61 FR 64272) to the EAR that redesignated TMP as § 740.8 and GFT as § 740.11. When TMP and GFT were redesignated, one footnote to paragraph (b)(1)(iv) in TMP (now § 740.9(b)(1)(iv)) and one footnote to paragraph (a)(1) in GFT (now § 740.12(a)(1)) were inadvertently omitted. This rule reinserts the footnote by ‘‘Commerce Form 7513’’ in § 740.9(b)(1)(iv) and the footnote by ‘‘gift parcel’’ in § 740.12(a)(1)). Part 740—Removal of Certain Countries from Country Group D Country Group D, as found in Supplement No. 1 to part 740, contains countries listed as countries of concern due to national security, nuclear, chemical and biological, and/or missile technology reasons. An ‘‘x’’ in a particular column indicates the reason(s) that applies to a particular country. On August 5, 1997, BIS (then BXA) published a final rule (62 FR 42047) which removed the ‘‘x’’ in the D:2 column for Algeria, Andorra, Comoros, Djibouti, Micronesia, and Vanuatu, to reflect their status as signatories of the Nuclear NonProliferation Treaty. As a result of that rule, those six countries did not have an ‘‘x’’ in any of the columns in Country Group D. However, the rule did not remove those countries’ names from the list of countries in that country group. Therefore, this rule removes references to those six countries from Country Group D.

Airworthiness Directives; Bell Helicopter Textron Canada Model 
430 Helicopters

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD) for 
Bell Helicopter Textron Canada (BHTC) Model 430 helicopters that 
requires replacing a certain servo actuator-to-actuator support 
attachment bolt (bolt) with an airworthy bolt. This action also 
requires establishing a retirement life for certain bolts and recording 
the retirement life on a component history card or equivalent record. 
This amendment is prompted by further evaluation of certain fatigue-
critical parts, resulting in establishing a life limit of 5,000 hours 
for the affected bolts. The actions specified by this AD are intended 
to prevent fatigue failure of the bolt and subsequent loss of control 
of the helicopter.

DATES: Effective February 6, 2008.

ADDRESSES: You may get the service information identified in this AD 
from Bell Helicopter Textron Canada, 12,800 Rue de l'Avenir, Mirabel, 
Quebec J7J1R4, telephone (450) 437-2862 or (800) 363-8023, fax (450) 
433-0272.
    Examining the Docket: You may examine the docket that contains this 
AD, any comments, and other information on the Internet at https://
www.regulations.gov or at the Docket Operations office, West Building 
Ground Floor, Room W12-140, 1200 New Jersey Avenue, SE., Washington,

FOR FURTHER INFORMATION CONTACT: Sharon Miles, Aviation Safety 
Engineer, FAA, Rotorcraft Directorate, Regulations and Guidance Group, 
Fort Worth, Texas 76193-0111, telephone (817) 222-5122, fax (817) 222-
5961.

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 16, 2007 (72 FR 38797). That action proposed 
to require replacing a certain bolt with an airworthy bolt. That action 
also proposed establishing a retirement life for certain bolts and 
recording the retirement life on a component history card or equivalent 
record.
    Transport Canada, the airworthiness authority for Canada, notified 
the FAA that an unsafe condition may exist on BHTC Model 430 
helicopters, serial numbers 49001 through 49106. Transport Canada 
advises of the need to establish a new airworthiness life limitation of 
5,000 hours for the three servo actuator support attachment bolts and 
to replace the three affected bolts.
    Bell Helicopter Textron has issued Alert Service Bulletin No. 430-
05-33, dated February 16, 2005 (ASB). The ASB introduces a retirement 
life of 5,000 hours for the bolts. The ASB states

[[Page 30]]

that since these bolts have not been listed in the Helicopter Component 
Replace record, it is difficult to determine with accuracy the actual 
number of hours accumulated on fielded bolts. Also, the ASB states that 
Bell has elected to replace all the fielded bolts, part number (P/N) 
50-047C8-31. Transport Canada classified this ASB as mandatory and 
issued AD No. CF-2005-09, dated April 14, 2005, to ensure the continued 
airworthiness of these helicopters in Canada.
    This helicopter model is manufactured in Canada and is 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 us informed 
of the situation described above. We have examined the findings of 
Transport Canada, reviewed all available information, and determined 
that AD action is necessary for products of this type design that are 
certificated for operation in the United States.
    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 with two changes. We corrected a 
paragraph under the ADDRESSES section in the preamble to reflect the 
correct address for getting the service information. Also, we added a 
Note to the AD stating that there is service information that pertains 
to the subject of the AD. We have determined that these changes will 
neither increase the economic burden on any operator nor increase the 
scope of the AD.
    We estimate that this AD will affect 54 helicopters of U.S. 
registry, and the required actions will take about 2 work hours per 
helicopter to replace 3 bolts at an average labor rate of $80 per work 
hour. Required parts will cost about $243 for each bolt. Based on these 
figures, we estimate the total cost impact of the AD on U.S. operators 
to be $ $48,006, assuming that the recordkeeping cost would be 
negligible.

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.
