 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2005-23145; Directorate Identifier 2000-NM-215-AD]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).
 ACTION: Notice of proposed rulemaking (NPRM).
 SUMMARY: The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all EMBRAER Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. The existing AD currently requires repetitive inspections to detect cracking or failure of the rod ends of the aileron power control actuator (PCA), and corrective actions if necessary. This proposed AD would require the same repetitive inspections of additional parts at new inspection intervals for certain airplanes; provide new corrective actions; and provide an optional terminating action for the proposed requirements. This proposed AD results from the issuance of mandatory continuing airworthiness information by the Brazilian airworthiness authority. We are proposing this AD to detect and correct cracking or breaking of the rod ends and connecting fittings of the aileron PCA, which could result in reduced controllability of the airplane.
 DATES: We must receive comments on this proposed AD by January 6, 2006.

                     section. Comments will be available in the AD docket shortly after the Docket Management System receives them. Discussion On March 16, 1999, we issued AD 99-05-04, amendment 39-11087 (64 FR 13892, March 23, 1999), for all EMBRAER Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. That AD requires repetitive inspections to detect cracking or failure of the rod ends of the aileron power control actuator (PCA), and corrective actions if necessary. That AD resulted from the issuance of mandatory continuing airworthiness information by the Brazilian civil aviation authority, the Departmento de Aviacao Civil (DAC). We issued that AD to detect and correct cracking or failure of the rod ends of the aileron PCA, which could result in reduced controllability of the airplane. Actions Since Existing AD Was Issued Since we issued AD 99-05-04, the DAC notified us that it has received additional reports of broken rod ends of the aileron PCA, involving part numbers (P/N) on which AD 99-05-04 did not apply. The rod ends were broken either at the aileron or at the wing side of the PCA. More recently, there have been reports of cracking in the aileron PCA fittings at the wing side. Failure/breaking of the aileron PCA rod ends or connecting fittings, if not corrected, could result in reduced controllability of the airplane. Relevant Service Information EMBRAER has issued the following service documents: 1. Service Bulletin 145-27-0054, Change 03, dated March 30, 2000; and Service Bulletin 145-27-0054, Change 
                    ( print page 72727)
                    04, dated February 14, 2005. For PCAs having certain P/Ns, these service bulletins describe procedures for repetitive visual inspections for cracking or failure of the aileron PCA rod ends and connecting fittings at the aileron connection points for the wing structure. Among other things, these service bulletins also describe procedures for corrective actions that include replacing PCAs that have cracked or failed rod ends with new PCAs, replacing cracked or failed fittings with new reinforced fittings, and replacing any aileron having any discrepancy found during the described inspections with a new or serviceable aileron. 2. Service Bulletin 145-57-0019, Change 02, dated May 3, 2001; and Service Bulletin 145-57-0019, Change 03, dated February 11, 2004. These service bulletins describe procedures for replacing all PCA connecting fittings with new, redesigned, and reinforced fittings in the half-wings, among other actions. EMBRAER recommends that these service bulletins be done at the same time as the actions in EMBRAER Service Bulletin 145-27-0061 and in EMBRAER Service Bulletin 145-27-0062 (both described below). 3. Service Bulletin 145-27-0061, Change 02, dated September 12, 2000; Service Bulletin 145-27-0061, Change 03, dated March 14, 2001; and Service Bulletin 145-27-0061, Revision 04, dated August 11, 2004. These service bulletins describe procedures for reinforcing the aileron PCA fittings and reidentifying the aileron. EMBRAER recommends that these service bulletins be done at the same time as the actions in EMBRAER Service Bulletins 145-57-0019 and 145-27-0062. 4. Service Bulletin 145-27-0062, Revision 03, dated December 11, 2002; and Service Bulletin 145-27-0062, Revision 04, dated March 8, 2004. For PCAs with certain P/Ns, these service bulletins describe procedures for replacing the aileron PCAs with new, improved aileron PCAs, among other actions. EMBRAER recommends that the actions in EMBRAER Service Bulletins 145-57-0019 and 145-27-0061 be done before the actions in these service bulletins. These service bulletins also specify that operators send the replaced PCAs to the parts manufacturer. 5. Service Bulletin 145-27-0063, dated March 30, 2000; Service Bulletin 145-27-0063, Change 01, dated October 2, 2000; Service Bulletin 145-27-0063, Change 02, dated March 22, 2002; Service Bulletin 145-27-0063, Change 03, dated May 27, 2004; Service Bulletin 145-27-0063, Revision 04, dated October 13, 2004; and Service Bulletin 145-27-0063, Revision 05, dated March 16, 2005. These service bulletins describe procedures for installing an aileron damper and modifying the hydraulic system, among other actions. 6. Subtask 27-12-01-212-002-A00 of the EMBRAER EMB-145 Aircraft Maintenance Manual. This subtask provides procedures for inspecting the aileron PCA rod ends and fitting lugs. The DAC mandated the service information and issued Brazilian airworthiness directive 1999-02-01R6, dated June 21, 2004, to ensure the continued airworthiness of these airplanes in Brazil. FAA's Determination and Requirements of the Proposed AD These airplane models are manufactured in Brazil and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DAC has kept the FAA informed of the situation described above. We have examined the DAC's findings, evaluated all pertinent information, and determined that AD action is necessary for airplanes of this type design that are certificated for operation in the United States. This proposed AD would supersede AD 99-05-04 and would continue to require repetitive inspections to detect cracking or failure of the rod ends of the aileron PCA, and corrective actions if necessary. This proposed AD would also: 1. Require the same repetitive inspections of additional P/Ns at new inspection intervals for certain airplanes; 2. Provide new corrective actions; 3. Require use of a new revision of the previously required service bulletin; and 4. Provide an optional terminating action for the proposed requirements. The proposed AD would require you to use the service information described previously to perform these actions. Differences Between the Proposed AD and the Brazilian Airworthiness Directive The Brazilian airworthiness directive does not give a compliance time for the initial inspection of the PCA rod ends and fittings. We would require that inspection to be done at the applicable time specified in the following table, “Compliance Times for Initial Inspection.” In developing an appropriate compliance time for this inspection, we considered the manufacturer's recommendation, the degree of urgency associated with the subject unsafe condition, the average utilization of the affected fleet, and the time necessary to perform the inspection (1 hour). We also considered that the referenced service bulletin (EMBRAER Service Bulletin 145-27-0054, Change 03, dated March 30, 2000), which contains the procedures for accomplishing the required inspection, has been available to all operators of the subject EMBRAER airplanes since March 2000. (EMBRAER Service Bulletin 145-27-0054, Change 03, was revised on February 14, 2005, to add two airplanes to the effectivity; we understand that the actions specified in the service bulletin have been accomplished on those two airplanes.) In light of all of these factors, we find that the initial inspection must be accomplished at the applicable time specified in the table below, which represents an appropriate interval of time allowable for affected airplanes to continue to operate without compromising safety. Table.—Compliance Times for Initial Inspection
For airplanes that have PCAs with these part numbers (P/N)—
Do the initial inspection—394900-1003 or 394900-1005
Within 3 days after the effective date of this AD.394900-1007
Within 14 days after the effective date of this AD.418800-1001, 418800-1003, 418800-9003, 418800-1005, 418800-9005, 418800-1007, or 418800-9007; and that have new reinforced PCA fittings installed in accordance with paragraph (k) or (l) of this AD
Within 500 flight hours after the effective date of this AD.
 
 
 The Brazilian airworthiness directive also does not give a compliance time for replacing cracked or failed PCA fittings or rod ends. This proposed AD would require replacing any cracked or failed part before further flight. In addition, the Brazilian airworthiness directive does not specify what operators should do when no cracked or failed aileron PCA rod ends or connecting fittings are found. This AD would require the inspection to be repeated at the intervals specified in the following table. Table.—Repeat Inspection Intervals
For airplanes that have PCAs with these part numbers (P/N)—
Repeat the inspection—394900-1003 or 394900-1005
At intervals not to exceed 25 flight hours or 3 days, whichever occurs later.394900-1007
At intervals not to exceed 100 flight hours or 14 days, whichever occurs later.418800-1001, 418800-1003, 418800-9003, 418800-1005, 418800-9005, 418800-1007, or 418800-9007; and that have new reinforced PCA fittings installed in accordance with paragraph (j) or (k) of this AD
At intervals not to exced 500 flight hours.
 These differences have been coordinated with the DAC and they are in agreement. Change to Existing AD This proposed AD would retain certain requirements of AD 99-05-04. Since AD 99-05-04 was issued, the AD format has been revised, and certain paragraphs have been rearranged. As a result, the corresponding paragraph identifiers have changed in this proposed AD, as listed in the following table: Revised Paragraph Identifiers
Requirement in AD 99-05-04
Corresponding requirement in this proposed ADParagraph (a)
Paragraph (f).Paragraph (b)
Paragraph (g).
 In addition, all references to a “detailed visual inspection” have been changed to refer to a “detailed inspection.” A definition of detailed inspection is included in Note 1 of the proposed AD. We have also removed the requirement in paragraph (c) of AD 99-05-04 to send a report of any cracked or failed rod end to the Manager, Atlanta Aircraft Certification Office, FAA. We no longer need this information from operators. Interim Action We consider this proposed AD interim action. If final action is later identified, we may consider further rulemaking then.

 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 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. For the reasons discussed above, I certify that the proposed 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 
                    ( print page 72729)
                    under the criteria of the Regulatory Flexibility Act. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. See the
