[Federal Register Volume 81, Number 8 (Wednesday, January 13, 2016)] [Rules and Regulations] [Pages 1494-1497] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2016-00004] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2015-1990; Directorate Identifier 2015-NM-027-AD; Amendment 39-18364; AD 2016-01-05] RIN 2120-AA64 Airworthiness Directives; The Boeing Company Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-400 series airplanes, as modified by a certain supplemental type certificate. This AD was prompted by the discovery of a design drawing error regarding placards that identified incorrect squibs and pressure switches for certain fire extinguisher bottles. This AD requires a detailed inspection of certain cargo placards to determine if they are the correct placards and in the correct location, a detailed inspection of the harnesses to verify that they are marked and installed correctly, and corrective action if necessary. We are issuing this AD to detect and correct incorrectly installed harnesses for the cargo fire suppression system bottles, which could result in an incorrect activation sequence of the bottles, the inability to suppress a cargo fire quickly, and a possible uncontrollable fire. DATES: This AD is effective February 17, 2016. [[Page 1495]] The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of February 17, 2016.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 737-400 series airplanes, as modified by a certain supplemental type certificate. The NPRM published in the Federal Register on July 2, 2015 (80 FR 38033). The NPRM was prompted by the discovery of a design drawing error regarding placards that identified incorrect squibs and pressure switches for certain fire extinguisher bottles. The NPRM proposed to require a detailed inspection of certain cargo placards to determine if they are the correct placards and in the correct location, a detailed inspection of the harnesses to verify that they are marked and installed correctly, and corrective action if necessary. We are issuing this AD to detect and correct incorrectly installed harnesses for the cargo fire suppression system bottles, which could result in an incorrect activation sequence of the bottles, the inability to suppress a cargo fire quickly, and a possible uncontrollable fire. Comments We gave the public the opportunity to participate in developing this AD. We have considered the comments received. The European Aviation Safety Agency stated that it is following the progress of this activity of the NPRM (80 FR 38033, July 2, 2015). Boeing stated that the NPRM does not address any Boeing designs; therefore, Boeing can neither review the data, nor comment on the content of the NPRM, and that no file attachment accompanies its comment. Conclusion We reviewed the relevant data, considered the comments received, 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 38033, July 2, 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 38033, July 2, 2015). Related Service Information Under 1 CFR Part 51 We reviewed Advanced Aircraft Extinguishers Service Bulletin TFA10- 26-0020, Revision IR, dated January 12, 2015. The service information describes procedures for a detailed inspection of Advanced Aircraft Extinguishers cargo fire protection system placards to determine if they are the correct placards and in the correct location, and applicable corrective actions; and a detailed inspection of the harnesses to verify that they are correctly marked and installed, and doing steps C.(5) through C.(11) of Advanced Aircraft Extinguishers Service Bulletin TFA10-26-0020, Revision IR, dated January 12, 2015, if necessary. This service 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. Costs of Compliance We estimate that this AD affects 3 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 ---------------------------------------------------------------------------------------------------------------- Detailed inspection................. 2 work-hours x $85 per N/A $170 $510 hour = $170. ---------------------------------------------------------------------------------------------------------------- We estimate the following costs to do any necessary corrective actions that will be required based on the results of the inspection. We have no way of determining the number of aircraft that might need these corrective actions: On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Cost per Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Corrective actions........................... 2 work-hours x $85 per hour = $900 $1,070 $170. ---------------------------------------------------------------------------------------------------------------- [[Page 1496]] According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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), (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.
