Download as PDF 31393 Proposed Rules Federal Register Vol. 70, No. 104 Wednesday, June 1, 2005 This section of the FEDERAL REGISTER contains notices to the public of the proposed issuance of rules and regulations. The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2004–19565; Directorate Identifier 2004–NM–104–AD] RIN 2120–AA64 Airworthiness Directives; Gulfstream Aerospace LP Model Galaxy and Gulfstream 200 Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Proposed rule; withdrawal. AGENCY: SUMMARY: The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Galaxy and Gulfstream 200 airplanes. That action would have required inspecting for incorrect torque of the retaining bolt of the aft trunnion of the main landing gear (MLG), and for associated damage to certain components, and adjustments or repairs if necessary. Since the issuance of the NPRM, we have received new data that the identified unsafe condition has been corrected on 100% of the affected worldwide fleet. Accordingly, the NPRM is withdrawn. ADDRESSES: You can examine the AD docket on the Internet at https:// dms.dot.gov, or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647–5227) is located on the plaza level of the Nassif Building at the U.S. Department of Transportation, 400 Seventh Street SW., room PL–401, Washington, DC. This docket number is FAA–2004–19565; the directorate identifier for this docket is 2004–NM– 104–AD. FOR FURTHER INFORMATION CONTACT: Dan Rodina, Aerospace Engineer, International Branch, ANM–116, FAA, Transport Airplane Directorate, 1601 VerDate jul<14>2003 14:50 May 31, 2005 Jkt 205001 Lind Avenue, SW., Renton, Washington 98055–4056; telephone (425) 227–2125; fax (425) 227–1149. SUPPLEMENTARY INFORMATION: Discussion We proposed to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) with a notice of proposed rulemaking (NPRM) for a new AD for certain Gulfstream Aerospace LP Model Galaxy and Gulfstream 200 airplanes. That NPRM was published in the Federal Register on November 10, 2004 (69 FR 65095). The NPRM would have required inspecting for incorrect torque of the retaining bolt of the aft trunnion of the main landing gear (MLG), and for associated damage to certain components, and adjustments or repairs if necessary. The NPRM was prompted by a report of a rumbling sound heard by the flightcrew during takeoff, and the rumbling stopped after the MLG was retracted. The proposed actions were intended to prevent damage to the retaining bolt and bearing of the aft trunnion of the MLG, which could result in reduced structural integrity of the MLG and consequent reduced controllability of the airplane on the ground. Actions Since NPRM Was Issued Since the issuance of that NPRM, the airplane manufacturer has provided us with data that indicate that the identified unsafe condition (damage to the retaining bolt and bearing of the aft trunnion of the MLG, which could result in reduced structural integrity of the MLG and consequent reduced controllability of the airplane on the ground) has already been corrected on 100% of the affected worldwide fleet. The actions required by the NPRM have been accomplished on all affected airplanes; therefore, the unsafe condition no longer exists on the subject airplanes. FAA’s Conclusions Upon further consideration, we have determined that the actions that would have been required by the NPRM have already been done on all affected airplanes, and the identified unsafe condition has been corrected. Accordingly, the NPRM is withdrawn. Withdrawal of the NPRM does not preclude the FAA from issuing another related action or commit the FAA to any course of action in the future. PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 Regulatory Impact Since this action only withdraws an NPRM, it is neither a proposed nor a final rule and therefore is not covered under Executive Order 12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety. The Withdrawal Accordingly, we withdraw the NPRM, Docket No. FAA–2004–19565; Directorate Identifier 2004–NM–104– AD, which was published in the Federal Register on November 10, 2004 (69 FR 65095). Issued in Renton, Washington, on May 23, 2005. Ali Bahrami, Manager, Transport Airplane Directorate, Aircraft Certification Service.

Discussion What events have caused this proposed AD? The FAA has received reports of chafing conditions in the powerplant left hand and right hand engine assembly cable, wire, and hose routing clearance. The incidents of chafing have been reported on airplane serial numbers: RB–20, RB–50, and RB– 101. Investigation revealed that the areas of concern include control cables, wiring harnesses, fluid and drain hoses, and support structure. Further, FAA has determined that the cause of the unsafe condition relates to the design and quality control. Raytheon has developed a kit and service information to correct the chafing conditions. What is the potential impact if FAA took no action? The existence of chafing conditions in the engine installation could result in leaking flammable fluids near an ignition source. This failure could lead to fire damage or loss of airplane control. Is there service information that applies to this subject? Raytheon has issued Service Bulletin No. SB 71–3685, Issued May 2005. What are the provisions of this service information? The service bulletin includes procedures for correcting chafing conditions in the engine installation. FAA’s Determination and Requirements of This Proposed AD What has FAA decided? We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other products of this same type design. For this reason, we are proposing AD action. What would this proposed AD require? This proposed AD would require you to incorporate the actions in the previously-referenced service bulletin. How does the revision to 14 CFR part 39 affect this proposed AD? On July 10, 2002, we published a new version of 14 CFR part 39 (67 FR 47997, July 22, 2002), which governs FAA’s AD system. This regulation now includes material that relates to altered products, special flight permits, and alternative methods of compliance. This material previously was included in each individual AD. Since this material is included in 14 CFR part 39, we will not include it in future AD actions. Costs of Compliance How many airplanes would this proposed AD impact? We estimate that this proposed AD affects 74 airplanes in the U.S. registry. What would be the cost impact of this proposed AD on owners/operators of the affected airplanes? We estimate the following costs to do this proposed installation of the kit to correct chafing conditions in the engine installation: Labor cost Parts cost Total cost per airplane Total cost on U.S. operators 16 work hours × $65 = $1,040 .................................................................................................... $1,775 $2,815 $208,310 VerDate jul<14>2003 14:50 May 31, 2005 Jkt 205001 PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 E:\FR\FM\01JNP1.SGM 01JNP1 Federal Register / Vol. 70, No. 104 / Wednesday, June 1, 2005 / Proposed Rules The labor and part costs are covered by Raytheon Aircraft Company warranty. Authority for This Rulemaking What authority does FAA have for issuing this rulemaking action? 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 AD. Regulatory Findings Would this proposed AD impact various entities? We have 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. Would this proposed AD involve a significant rule or regulatory action? For the reasons discussed above, I certify that this proposed 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 a summary of the costs to comply with this proposed AD (and other information as included in the Regulatory Evaluation) and placed it in the AD Docket. You may get a copy of this summary by sending a request to us at the address listed under ADDRESSES. Include ‘‘AD Docket FAA–2005–21239; Directorate Identifier 2005–CE–27–AD’’ in your request.

Discussion

    What events have caused this proposed AD? The FAA has received 
reports of chafing conditions in the powerplant left hand and right 
hand engine assembly cable, wire, and hose routing clearance. The 
incidents of chafing have been reported on airplane serial numbers: RB-
20, RB-50, and RB-101.
    Investigation revealed that the areas of concern include control 
cables, wiring harnesses, fluid and drain hoses, and support structure. 
Further, FAA has determined that the cause of the unsafe condition 
relates to the design and quality control.
    Raytheon has developed a kit and service information to correct the 
chafing conditions.
    What is the potential impact if FAA took no action? The existence 
of chafing conditions in the engine installation could result in 
leaking flammable fluids near an ignition source. This failure could 
lead to fire damage or loss of airplane control.
    Is there service information that applies to this subject? Raytheon 
has issued Service Bulletin No. SB 71-3685, Issued May 2005.
    What are the provisions of this service information? The service 
bulletin includes procedures for correcting chafing conditions in the 
engine installation.

FAA's Determination and Requirements of This Proposed AD

    What has FAA decided? We have evaluated all pertinent information 
and identified an unsafe condition that is likely to exist or develop 
on other products of this same type design. For this reason, we are 
proposing AD action.
    What would this proposed AD require? This proposed AD would require 
you to incorporate the actions in the previously-referenced service 
bulletin.
    How does the revision to 14 CFR part 39 affect this proposed AD? On 
July 10, 2002, we published a new version of 14 CFR part 39 (67 FR 
47997, July 22, 2002), which governs FAA's AD system. This regulation 
now includes material that relates to altered products, special flight 
permits, and alternative methods of compliance. This material 
previously was included in each individual AD. Since this material is 
included in 14 CFR part 39, we will not include it in future AD 
actions.

Costs of Compliance

    How many airplanes would this proposed AD impact? We estimate that 
this proposed AD affects 74 airplanes in the U.S. registry.
    What would be the cost impact of this proposed AD on owners/
operators of the affected airplanes? We estimate the following costs to 
do this proposed installation of the kit to correct chafing conditions 
in the engine installation:

Authority for This Rulemaking

    What authority does FAA have for issuing this rulemaking action? 
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 AD.

Regulatory Findings

    Would this proposed AD impact various entities? We have 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.
    Would this proposed AD involve a significant rule or regulatory 
action? For the reasons discussed above, I certify that this proposed 
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 a summary of the costs to comply with this proposed AD 
(and other information as included in the Regulatory Evaluation) and 
placed it in the AD Docket. You may get a copy of this summary by 
sending a request to us at the address listed under ADDRESSES. Include 
``AD Docket FAA-2005-21239; Directorate Identifier 2005-CE-27-AD'' in 
your request.
