RIN 2120-AA64
 AGENCY: Federal Aviation Administration, DOT.
 ACTION: Final rule.
 SUMMARY: This amendment adopts a new airworthiness directive (AD), applicable to certain Model EMB-135 and -145 series airplanes. This AD requires modification of the pitch trim system, which includes replacing certain components of the system with new or serviceable components, and upgrading certain software to a newer version. This action is necessary to prevent the temporary loss of the pitch trim command, which could result in reduced controllability of the airplane and consequent injury to the flightcrew and passengers. This action is intended to address the identified unsafe condition.
 DATES: Effective January 26, 2005. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of January 26, 2005.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an airworthiness directive (AD) that is applicable to certain Model EMB-135 and -145 series airplanes was published in the 
                    **Federal Register**
                     on February 6, 2004 (69 FR 5759). That action proposed to require modification of the pitch trim system, which includes replacing certain components of the system with new or serviceable components, and upgrading certain software to a newer version. Comments Interested persons have been afforded an opportunity to participate in the making of this amendment. Due consideration has been given to the comments received. Request To Include New Revision of Service Bulletin 145-31-0042 One commenter requests that we use EMBRAER Service Bulletin 145-31-0042, Revision 01, dated January 7, 2004, as the appropriate source of service information for replacing certain integrated computers (IC) in paragraph (b)(4) of the proposed AD. The commenter states that the ICs in this service bulletin are upgrades, and classified as optional replacements for the IC-600 computers referenced in EMBRAER Service Bulletin 145-31-0033, Revision 03, dated August 25, 2003, which is the appropriate source of service information for replacing certain IC-600 computers per paragraph (b)(4) of the proposed AD. We partially agree with the commenter's request. We agree that EMBRAER Service Bulletin 145-31-0042, Revision 01, may be used as an optional source of service information for doing the actions in paragraph (b)(4) 
                    ( print page 76606)
                    of the AD. Additionally, the manufacturer has also issued Revision 02, dated June 23, 2004, and it may also be used as an optional source of service information. Since these revisions are not the only source of appropriate service information, operators may still choose to do the replacement in accordance with the service information in the proposed AD. Therefore, we have revised paragraph (b)(4) of this final rule to include EMBRAER Service Bulletin 145-31-0042, Revision 01 and Revision 02, as sources of service information for operators of airplanes listed in that service bulletin to choose as an optional way to replace the IC-600 computers as proposed in paragraph (b)(4). This optional replacement includes reidentifying IC-600 #1 and IC-600 #2, and loading a new configuration file to the IC-600 #1 and IC-600 #2 configuration modules. EMBRAER Service Bulletin 145-31-0042 references Honeywell Service Bulletin 7017000-22-6102, dated November 25, 2003, as an additional source of service information for accomplishing the upgrade and re-identification. EMBRAER Service Bulletin 145-31-0042 also contains other procedures that are not applicable to the IC-600 upgrade, but these actions are not required by this final rule. EMBRAER Service Bulletin 145-31-0042 specifies that the following service bulletins must be accomplished previously, as applicable, on the airplanes listed in these service bulletins: EMBRAER Service Bulletin 145-31-0020, Change 03, dated July 30, 2002, which contains procedures for replacing the IC-600 #1 and IC-600 #2, and the data acquisition unit (DAU); and for upgrading the engine indicating and crew alerting system (EICAS) to version 17.
                EMBRAER Service Bulletin 145-25-0210, dated March 30, 2001, which describes procedures for removing and/or replacing certain placards in the cockpit. These placards are related to the EICAS.
                EMBRAER Service Bulletin 145-45-0003, dated July 5, 2000, which describes procedures for modifying and re-identifying the central maintenance computer (CMC). This service bulletin refers to Vibro-Meter Service Bulletin 145-45-0503, dated March 20, 2000, as an additional source of service information for modifying and re-identifying the CMC. The Vibro-Meter service bulletin is included with EMBRAER Service Bulletin 145-45-0003. Request To Include New Revision of Service Bulletin 145LEG-27-0002 Another commenter requests that we refer to EMBRAER Service Bulletin 145LEG-27-0002, Revision 01, dated April 15, 2003, as the appropriate source of service information for accomplishing the actions in paragraphs (b)(1) and (b)(7) of the proposed AD on Model EMB-135BJ series airplanes. The commenter advises that this is the latest revision of the service bulletin with the most current information. We agree with the commenter. The new revision of the service bulletin identifies two new and improved horizontal stabilizer control units (HSCU), and reduces the number of airplanes to which this service bulletin applies. We have revised the applicability section, paragraphs (b)(1) and (b)(7), and Table 1 of the final rule to include references to EMBRAER Service Bulletin 145LEG-27-0002, Revision 01. We have also revised Table 2 of the final rule to include a reference to the original issue of EMBRAER Service Bulletin 145LEG-27-0002, dated February 5, 2003. EMBRAER Service Bulletin 145LEG-27-0002 is applicable to Model EMB-135BJ series airplanes, and describes procedures for replacing the HSCU with a new unit having improved features. This service bulletin also describes procedures for connecting the HSCU and the DAU (including the replacement of the pitch trim system circuit breakers with new circuit breakers sized for the new system load capacity, as applicable). Request To Extend Compliance Time One commenter, an airplane operator, requests that the compliance time for accomplishing the seven actions in paragraph (b) of the proposed AD be extended to better accommodate the commenter's existing maintenance program. The compliance time, as proposed, is: “Within 18 months or 5,000 flight hours after the effective date of this AD, whichever occurs first.” The commenter requests that the statement be revised to say, “Within 18 months or 5,000 flight hours after the effective date of this AD, whichever occurs later,” or, “Within 36 months or 5,000 flight hours after the effective date of this AD, whichever occurs first.” The commenter states that 5,000 flight hours work better with its existing maintenance program, and that 36 months is approximately equivalent to 5,000 flight hours for its operation. The commenter requests the extension in order to comply with the requirements of the proposed AD in a smooth and effective manner, and to reduce the time and effort to the commenter and the FAA in requesting and addressing alternative methods of compliance (AMOCs). We do not agree with the commenter's request to extend the compliance time. The commenter provides no technical justification that extending the compliance time will still maintain an appropriate level of safety. In developing an appropriate compliance time for this proposed AD, we considered safety issues as well as the recommendations of the manufacturer and the Departmento de Aviacao Civil, (which is the airworthiness authority for Brazil), the availability of necessary parts, and the practical aspects of accomplishing the required actions within an interval of time that corresponds to the normal maintenance schedules of most affected operators. We do not find it necessary to change this proposal in this regard; however, the commenter still may apply for approval of an AMOC to extend the compliance time. Request To Shorten Compliance Time Another commenter supports the proposal and requests that the compliance time for accomplishing the proposed actions be shortened substantially. The commenter states that the unsafe condition is severe enough to warrant a more immediate compliance time. In addition, the commenter understands that the parts necessary to complete the modification are readily available and, therefore, the parts should be available to accomplish the proposed actions more quickly. We do not agree that the unsafe condition is severe enough to justify shortening the compliance time substantially. The proposed compliance time was determined to be appropriate in consideration of the safety implications, the average utilization rate of the affected fleet, the practical aspects of modifications during regular maintenance periods, and the availability of required modification parts. We do agree with the commenter that parts are available to accomplish the actions in the allotted time in the original NPRM. We have not revised the proposal to shorten the compliance time. Request To Remove “Interim Action” Another commenter, the airplane manufacturer, requests that we remove the section of the NPRM that describes this proposal as “interim action.” The commenter states that the corrective action in the proposal completely addresses the specific unsafe conditions identified during the development of the Brazilian airworthiness directive 
                    ( print page 76607)
                    and the FAA NPRM. In addition, the commenter states that recent pitch trim failures induced by airspeed miscompares will be addressed by a new HSCU that is under development. Therefore, the commenter believes that it is not appropriate to label this proposal as “interim action.” We agree that the NPRM was issued to correct the stated known unsafe condition. In stating that the proposal is “interim action,” we are advising the public that rulemaking on this subject may be issued in the future. This additional rulemaking could include a new HSCU that is under development. We have not changed the proposal to remove the reference to “interim action.” Conclusion After careful review of the available data, including the comments noted above, the FAA has determined that air safety and the public interest require the adoption of the rule with the changes described previously. The FAA has determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD. Cost Impact There are approximately 365 airplanes of U.S. registry affected by this AD. For all affected airplanes, we estimate that it will take approximately 1 work hour per airplane to replace the HSCU, and that the average labor rate is $65 per work hour. The manufacturer will provide replacement parts at no cost. Based on these figures, the cost impact of this replacement on U.S. operators is estimated to be $23,725, or $65 per airplane. For airplanes subject to EMBRAER Service Bulletin 145-27-0091, we estimate that it will take approximately 6 work hours per airplane to replace the horizontal stabilizer actuator, and that the average labor rate is $65 per work hour. The manufacturer will provide replacement parts at no cost. Based on these figures, the cost impact of this replacement is estimated to be $390 per airplane. For airplanes subject to EMBRAER Service Bulletin 145-31-0028, we estimate that it will take approximately 2 work hours per airplane to replace the aural warning unit, and that the average labor rate is $65 per work hour. Required parts will cost approximately $1,100 per airplane. Based on these figures, the cost impact of this replacement is estimated to be $1,230 per airplane. For airplanes subject to EMBRAER Service Bulletin 145LEG-31-0001 or 145-31-0033; or on which the optional action in EMBRAER Service Bulletin 145-31-0042 is done, we estimate that it will take between 1 and 6 work hours per airplane to install the new EICAS/electronic flight information system, and that the average labor rate is $65 per work hour. Required parts will cost between $10 and $25 per airplane. Based on these figures, the cost impact of this action is estimated to be between $75 and $415 per airplane. For airplanes subject to EMBRAER Service Bulletin 145LEG-27-0004 or 145-27-0096, we estimate that it will take between 4 and 5 work hours per airplane to replace the yoke pitch trim switch, and that the average labor rate is $65 per work hour. Required parts will cost between $1,042 and $1,056 per airplane. Based on these figures, the cost impact of this action is estimated to be between $1,302 and $1,381 per airplane. For airplanes subject to EMBRAER Service Bulletin 145-27-0073, we estimate that it will take approximately 3 work hours per airplane to replace the pitch trim back-up control switch, and that the average labor rate is $65 per work hour. Required parts will cost approximately $371 per airplane. Based on these figures, the cost impact of this replacement is estimated to be $566 per airplane. For airplanes subject to the requirements in EMBRAER Service Bulletin 145-27-0083, we estimate that it will take approximately 38 hours to accomplish the modifications, and that the average labor rate is $65 per work hour. Required parts will cost approximately $448. Based on these figures, the cost impact of these modifications is estimated to be $2,918 per airplane. For airplanes subject to the requirements in EMBRAER Service Bulletin 145-31-0020, we estimate that it will take between 9 and 56 hours to accomplish the proposed upgrade, and that the average labor rate is $65 per work hour. Required parts will cost between $3 and $5,100. Based on these figures, the cost impact of this action is estimated to be approximately between $588 and $8,740 per airplane. For all affected airplanes, we estimate that it will take between 1 and 3 hours per airplane to accomplish the connection between the HSCU and the DAU specified in EMBRAER Service Bulletin 145LEB-27-0002, and that the average labor rate is $65 per work hour. Required parts will cost between $3 and $52 per airplane. Based on these figures, the cost impact of this action is estimated to be between $24,820 and $90,155, or between $68 and $247 per airplane. The cost impact figures discussed above are based on assumptions that no operator has yet accomplished any of the requirements of this AD action, and that no operator would accomplish those actions in the future if this AD were not adopted. The cost impact figures discussed in AD rulemaking actions represent only the time necessary to perform the specific actions actually required by the AD. These figures typically do not include incidental costs, such as the time required to gain access and close up, planning time, or time necessitated by other administrative actions. Regulatory Impact The regulations adopted herein 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. Therefore, it is determined that this final rule does not have federalism implications under Executive Order 13132. For the reasons discussed above, I certify that this action (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. A final evaluation has been prepared for this action and it is contained in the Rules Docket. A copy of it may be obtained from the Rules Docket at the location provided under the caption
