[Federal Register: October 29, 2009 (Volume 74, Number 208)] [Rules and Regulations] [Page 55755-55757] From the Federal Register Online via GPO Access [wais.access.gpo.gov] [DOCID:fr29oc09-2] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2009-0314; Directorate Identifier 2008-NM-196-AD; Amendment 39-16066; AD 2009-22-13] RIN 2120-AA64 Airworthiness Directives; Boeing Model 767-200, -300, -300F, and -400ER Series Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain Boeing Model 767-200, -300, -300F, and -400ER series airplanes. This AD requires an inspection to determine if certain motor operated valve actuators for the fuel tanks are installed, and related investigative and corrective actions if necessary. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent an ignition source inside the fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. DATES: This AD is effective December 3, 2009. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of December 3, 2009. ADDRESSES: For service information identified in this AD, contact Boeing Commercial Airplanes, Attention: Data & Services Management, P.O.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to certain Boeing Model 767-200,-300, -300F, and -400ER series airplanes. That NPRM was published in the Federal Register on April 7, 2009 (74 FR 15681). That NPRM proposed to require an inspection to determine if certain motor operated valve actuators for the fuel tanks are installed, and related investigative and corrective actions if necessary. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received. Request To Include an Additional Part Number for Serviceable MOV Actuators ABX Air asks that the NPRM include part number (P/N) MA30A1001 as a serviceable actuator acceptable for installation. ABX states that the NPRM would not allow serviceable actuators having part number MA30A1001 to be installed. ABX adds that requiring installation of only new MOV actuators having P/N MA30A1001 would impose an undue burden on operators. We agree to include installation of serviceable MOV actuators having P/N MA30A1001 in this AD. The intent of the AD is to replace MOV actuators having P/N MA20A1001-1 with a new or serviceable replacement part. We have revised paragraph (h) of this AD to allow installation of serviceable MOV actuators having P/N MA30A1001. Request To Include Revision 1 of the Reference Service Bulletin Boeing asks that paragraphs (c), (g)(1), (g)(2), and (h) of the NPRM be changed to include Revision 1 of Boeing Alert Service Bulletin 767-28A0090, in addition to the original issue, dated July 3, 2008, referred to for the applicability and accomplishing the actions in the NPRM. Boeing states that operators will be burdened with tracking incorporation of Revision 1 as an alternative method of compliance if it is not included in the final rule. We do not agree to include Revision 1 of the referenced service bulletin in this AD, since a revision to Boeing Alert Service Bulletin 767-28A0090, dated July 3, 2008, has not yet been issued. Boeing has informed us that the revision to Boeing Alert Service Bulletin 767- 28A0090, when issued, will not have additional work to be performed and will not expand the scope of the AD. Since Boeing Alert Service Bulletin 767-28A0090 is expected to be revised after issuance of this AD, we might consider approving the revised service bulletin as an alternative method of compliance (AMOC), as provided by paragraph (i)(1) of this AD. Request To Revise the Costs of Compliance Section Boeing also asks that we consider revising the Costs of Compliance section specified in the NPRM to project more accurate cost estimates. Boeing states that the cost estimates do not seem accurate. Boeing adds that the parts costs for the replacement are substantial, and, when the replacement parts costs are added to the costs of labor, estimated work-hours, and the total number of airplanes affected, the cost estimates would be substantially higher than the estimate in the NPRM. We agree that the work-hours for the inspection should be higher than estimated in the NPRM. We have determined that it takes between 2 and 4 work-hours to perform the inspection, [[Page 55756]] depending on airplane configuration. We have changed the Costs of Compliance section (below) to expand the work-hour estimate. We do not agree that the parts cost for replacement should be included. The data in the Costs of Compliance section are limited only to the cost of actions actually required by the AD. The cost analysis in AD rulemaking actions does not include the costs of ``on-condition'' actions (e.g., ``repair or replace, if necessary'') or replacement parts that are necessary when doing those on-condition actions. Regardless of AD direction, those actions would be required to correct an unsafe condition identified in an airplane and ensure operation of that airplane in an airworthy condition. Therefore, we have made no change to the AD in this regard. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We also determined that these changes will not increase the economic burden on any operator or increase the scope of the AD. Costs of Compliance We estimate that this AD affects 397 airplanes of U.S. registry. We also estimate that it takes between 2 and 4 work-hours per product to comply with this AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be between $63,520 and $127,040, or between $160 and $320 per product. 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. Regulatory Findings 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 this AD: (1) Is not a ``significant regulatory action'' under Executive Order 12866, (2) Is not a ``significant rule'' under 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. You can find our regulatory evaluation and the estimated costs of compliance in the AD Docket.
