[Federal Register Volume 80, Number 188 (Tuesday, September 29, 2015)] [Rules and Regulations] [Pages 58354-58357] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2015-24249] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2015-2207; Directorate Identifier 2015-CE-003-AD; Amendment 39-18272; AD 2015-19-10] RIN 2120-AA64 Airworthiness Directives; M7 Aerospace LLC Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are superseding Airworthiness Directive (AD) 97-02-02 for certain Models SA26-AT, SA26-T, SA226-AT, SA226-T, SA226-T(B), SA226- TC, SA227-AC (C-26A), SA227-AT, SA227-BC (C-26A), SA227-CC, SA227-DC (C-26B), and SA227-TT airplanes. AD 97-02-02 required applying torque to the control column pitch bearing attaching nuts, inspecting the bearing assembly, inspecting the elevator control rod end bearing retainer/dust seals, and replacing or installing new parts as necessary. This new AD requires inspecting for movement and correct torque of the elevator control pivot bearing, inspecting the elevator control rod for damage and correct configuration, and replacing parts as necessary. This AD also requires a 10,000-hour time-in-service (TIS) repetitive replacement of the control column pivot bearing and elevator control rod bolt and requires replacement of the control column pivot bearing with the improved design by 35,000 hours TIS. This AD was prompted by loss of elevator control due to failure of the bolt attaching the elevator control rod to the elevator walking beam under the cockpit floor. We are issuing this AD to correct the unsafe condition on these products. DATES: This AD is effective November 3, 2015. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of November 3, 2015.

FOR FURTHER INFORMATION CONTACT: Andrew McAnaul, Aerospace Engineer, FAA, ASW-143 (c/o San Antonio MIDO), 10100 Reunion Place, Suite 650, San Antonio, Texas 78216; phone: (210) 308-3365; fax: (210) 308-3370; email: [email protected]. SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 97-02-02, Amendment 39-9886 (62 FR 2552, January 17, 1997), (``AD 97-02-02''). AD 97-02-02 applied to certain M7 Aerospace LLC Models SA26-AT, SA26-T, SA226-AT, SA226-T, SA226-T(B), SA226-TC, SA227-AC (C-26A), SA227-AT, SA227-BC (C-26A), SA227-CC, SA227-DC (C-26B), and SA227-TT airplanes. The NPRM published in the Federal Register on June 16, 2015 (80 FR 34326). The NPRM was prompted by an operator experiencing complete loss of elevator control due to failure of the bolt attaching the elevator control rod to the elevator walking beam under the cockpit floor. A follow-on inspection of the operator's fleet revealed a variety of hardware installed. Some hardware matched the illustrated parts catalog (IPC), some matched the AD 97-02-02 configuration, and some matched neither of those configurations. When AD 97-02-02 was issued, the IPC was never revised to match the hardware configuration called out in AD 97-02-02 or in the service information associated with that AD. Because of the conflict between the AD and the IPC configurations, an airplane that was in compliance with the requirements of AD 97-02-02 could have had an incorrect hardware configuration installed during routine maintenance after complying with the AD. The IPC has been updated and corrected by M7 Aerospace, LLC. Also, since we issued AD 97-02-02, the manufacturer developed an improved design for the control column pivot bearing and support structure that terminates the repetitive torque check and replacement of control column pivot bearings. The manufacturer also issued new service information that adds the 10,000-hour TIS repetitive replacement of the control column pivot bearing that is in the airworthiness limitations section (ALS) of the airplane maintenance manual (AMM) and (if this revision is mandated) requires the replacement of the pivot bearing with the improved design by 35,000 hours TIS that is in the supplemental inspections document (SID). Issuance of [[Page 58355]] the new service information, the revised IPC, and this AD will eliminate the conflicts between AD 97-02-02, the service information, the IPC, the ALS, and the SID. The NPRM (80 FR 34326, June 16, 2015) proposed to require inspecting for movement and correct torque of the elevator control pivot bearing, inspecting the elevator control rod for damage and correct configuration, and replacing parts as necessary. The NPRM also proposed to require a 10,000-hour TIS repetitive replacement of the control column pivot bearing and elevator control rod bolt and require replacement of the control column pivot bearing with the improved design by 35,000 hours TIS. Replacing the original control column pivot bearing with the improved design terminates the requirement to repetitively replace the original control column pivot bearing every 10,000 hours. We are issuing this AD to correct the unsafe condition on these products. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (80 FR 34326, June 16, 2015) or on the determination of the cost to the public. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes:Are consistent with the intent that was proposed in the NPRM (80 FR 34326, June 16, 2015) for correcting the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM (80 FR 34326, June 16, 2015). Relevant Service Information Under 1 CFR 51 We reviewed M7 Aerospace SA26 Series Service Bulletin No. 26-27-30- 046 R2, dated December 5, 2014; Fairchild Aircraft SA26 Series Service Bulletin No. 26-27-30-047, dated June 16, 1997; M7 Aerospace SA226 Series Service Bulletin No. 226-27-060 R2, dated December 5, 2014; Fairchild Aerospace SA226 Series Service Bulletin No. 226-27-061, dated June 16, 1997; M7 Aerospace SA227 Series Service Bulletin, No. 227-27- 041 R2, dated December 5, 2014; Fairchild Aircraft SA227 Series Service Bulletin No. 227-27-042, dated June 16, 1997; M7 Aerospace LLC SA227 Series Commuter Category Service Bulletin No. CC7-27-010 R2, dated December 5, 2014; and Fairchild Aircraft SA227 Series Commuter Category Service Bulletin No. CC7-27-011, dated June 16, 1997. The service information describes procedures for inspecting for movement and correct torque of the elevator control pivot bearing, inspecting the elevator control rod for damage, and replacing parts as necessary. The service information also adds a repetitive replacement of the control column pivot bearings at 10,000 hours TIS and requires replacement of the control column pivot bearing with the improved design within 35,000 hours TIS. This information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section of this AD. Costs of Compliance We estimate that this AD affects 360 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Inspection of torque on the 2 work-hours x $85 Not applicable......... $170 $61,200 control column pivot bearing. per hour = $170. Control column pivot bearing 8 work-hours x $85 $300................... 980 352,800 replacement. per hour = $680. New designed control column pivot 20 work-hours x $85 $2,450................. 4,150 1,494,000 bearing replacement. per hour = $1,700. Elevator rod end bolt replacement 4 work-hours x $85 $10.................... 350 126,000 per hour = $340. ---------------------------------------------------------------------------------------------------------------- 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 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), (3) Will not affect intrastate aviation in Alaska, and (4) 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. [[Page 58356]] Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD) 97-02-02, Amendment 39-9886 (62 FR 2552, January 17, 1997), and adding the following new AD: 2015-19-10 M7 Aerospace: Amendment 39-18272; Docket No. FAA-2015- 2207; Directorate Identifier 2015-CE-003-AD. (a) Effective Date This AD is effective November 3, 2015. (b) Affected ADs This AD supersedes AD 97-02-02, Amendment 39-9886 (62 FR 2552, January 17, 1997). (c) Applicability This AD applies to M7 Aerospace LLC Models SA26-AT, SA26-T, SA226-AT, SA226-T, SA226-T(B), SA226-TC, SA227-AC (C-26A), SA227-AT, SA227-BC (C-26A), SA227-CC, SA227-DC (C-26B), SA227-TT, all serial numbers, certificated in any category. (d) Subject Joint Aircraft System Component (JASC)/Air Transport Association (ATA) of America Code 27, Flight Controls. (e) Unsafe Condition AD 97-02-02 (62 FR 2552, January 17, 1997) (``AD 97-02-02'') resulted from reports of Fairchild SA227 series airplanes losing pitch control in-flight. This supersedure was prompted by an operator experiencing complete loss of elevator control because of failure of the bolt attaching the elevator control rod to the elevator walking beam under the cockpit floor. We are issuing this AD to prevent loss of pitch control, which if not corrected, could result in loss of airplane control. (f) Compliance Comply with this AD within the compliance times specified, unless already done. Models SA227-CC and SA227-DC, serial numbers 892, 893, and 895 and up, have the revised (modified) configuration. Since those airplanes are already in compliance, they do not have to do the actions in paragraphs (h) or (i) of this AD, including all subparagraphs. Those airplanes must still do the actions required in paragraph (j) of this AD, including all subparagraphs. (g) Credit for Actions Accomplished in Accordance With Previous Service Information This AD allows credit for the control column pivot bearing torque check and initial replacement required in paragraph (i)(2) of this AD and the elevator rod bolt inspection and initial replacement required in paragraphs (j)(1) and (j)(3)(i) of this AD, if done before November 3, 2015 (the effective date of this AD), following the procedures specified in the Accomplishment Instructions of the applicable service information listed in paragraphs (g)(1) through (g)(4) of this AD: (1) M7 Aerospace SA227 Commuter Category Service Bulletin No. CC7-27-010, original issue or revision 1.
