[Federal Register Volume 82, Number 193 (Friday, October 6, 2017)] [Proposed Rules] [Pages 46722-46724] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 2017-21366] [[Page 46722]] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2017-0905; Product Identifier 2017-NM-090-AD] RIN 2120-AA64 Airworthiness Directives; The Boeing Company Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to supersede Airworthiness Directive (AD) 2013-01- 02, which applies to certain The Boeing Company Model 747-100, 747- 100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes; and Model 757- 200, -200PF, and -300 series airplanes. AD 2013-01-02 requires replacing the control switches of certain cargo doors. Since we issued AD 2013-01-02, additional un-commanded cargo door operation has been reported. This proposed AD would require replacement of certain cargo door control switches with a new improved switch; installation of an arm switch in certain cargo doors; operational and functional tests; and applicable on-condition actions. This proposed AD would also add airplanes to the applicability. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by November 20, 2017.

Discussion On January 4, 2013, we issued AD 2013-01-02, Amendment 39-17316 (78 FR 4051, January 18, 2013) (``AD 2013-01-02''), for certain The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747- 200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes; and Model 757-200, -200PF, and -300 series airplanes. AD 2013-01-02 requires replacing the control switches of the forward, aft, and nose cargo doors of Model 747 airplanes; and replacing the control switches of cargo doors 1 and 2 of Model 757 series airplanes. AD 2013- 01-02 resulted from reports of problems associated with the uncommanded operation of cargo doors. We issued AD 2013-01-02 to prevent injuries to persons and damage to the airplane. Actions Since AD 2013-01-02 Was Issued Since we issued AD 2013-01-02, additional un-commanded cargo door operation has been reported. In the most recent report the switch had only been installed for 44 months. Testing of failed switches found that the cargo door control switch can remain actuated after released to the OFF position. We have determined that the replacements required by AD 2013-01-02 do not adequately address the identified unsafe condition and that new improved switches must be installed. With a new cargo door control and arm switch configuration installed, the operator must manually move both switches to operate the cargo door. Both switches are spring loaded to the off position and releasing either switch will stop the door operation. We have also determined that certain Model 757-200CB series airplanes and Model 747-8F and 747-8 series airplanes are affected by the identified unsafe condition and must be included in this proposed AD. Related Service Information Under 1 CFR Part 51 We reviewed the following Boeing service information. Boeing Service Bulletin 747-52-2307, dated May 23, 2017, and Boeing Service Bulletin 747-52-2308, dated June 5, 2017. This service information describes procedures for replacement of the nose, forward, and aft cargo door control switches with new improved switches, installation of an arm switch in the forward and aft cargo doors, a nose cargo door normal operational test, forward and aft cargo door open and close functional tests, and applicable on-condition actions. These documents are distinct since they apply to different airplane models in different configurations. Boeing Service Bulletin 757-52-0093, Revision 1, dated April 21, 2017. This service information describes procedures for replacement of the forward and aft cargo door control [[Page 46723]] switches with new improved switches, installation of an arm switch in the forward and aft cargo doors, an operational test of the No. 1 and No. 2 cargo doors, repetitive functional tests of the No. 1 and No. 2 cargo doors, and applicable on-condition actions. 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. FAA's Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of these same type designs. Proposed AD Requirements This proposed AD would retain none of the requirements of AD 2013- 01-02. This proposed AD would require accomplishing the actions identified as ``RC'' (required for compliance) in the Accomplishment Instructions of Boeing Service Bulletin 747-52-2307, dated May 23, 2017; Boeing Service Bulletin 747-52-2308, dated June 5, 2017; and Boeing Service Bulletin 757-52-0093, Revision 1, dated April 21, 2017; as applicable; except for any differences identified as exceptions in the regulatory text of this proposed AD. This proposed AD also would add airplanes to the applicability. For information on the procedures and compliance times, see this service information at https://www.regulations.gov by searching for and locating Docket No. FAA-2017-0905. Differences Between This Proposed AD and the Service Information The effectivity of Boeing Service Bulletin 757-52-0093, Revision 1, dated April 21, 2017, is limited to Model 757-200, -200CB, -200PF, and -300 series airplanes, line numbers 1 through 1050. However, the applicability of this proposed AD includes four additional Model 757 airplanes, variable numbers NP901 through NP904 inclusive. We have included this difference because of new findings related to these additional airplanes indicating they are subject to the identified unsafe condition. This difference has been coordinated with Boeing. Additionally, Boeing has indicated that Boeing Service Bulletin 757-52- 0093, Revision 1, dated April 21, 2017, will be revised to include the additional airplanes. We will consider including the revised service information, if available, in the final rule. Costs of Compliance We estimate that this proposed AD affects 584 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs for Required Actions ---------------------------------------------------------------------------------------------------------------- Cost on U.S. Action Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Replacement (Boeing Service 78 work-hours x $12,874 $19,504................ $273,056. Bulletin $85 per hour = 747[dash]52[dash]2307) (14 $6,630. airplanes). Replacement (Boeing Service 24 work-hours x 980 3,020.................. 283,880. Bulletin $85 per hour = 747[dash]52[dash]2308) (94 $2,040. airplanes). Replacement (Boeing Service 51 work-hours x 10,626 14,961................. 7,121,436. Bulletin $85 per hour = 757[dash]52[dash]0093) (476 $4,335. airplanes). Repetitive Test (Boeing 3 work-hours x 0 255 per test cycle..... 121,380 per test Service Bulletin $85 per hour = cycle. 757[dash]52[dash]0093) (476 $255 per test airplanes). cycle. ---------------------------------------------------------------------------------------------------------------- According to the manufacturer, some of the costs of this proposed 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 available 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. This proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. Regulatory Findings We 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 this 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), (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. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: [[Page 46724]] 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. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD) 2013-01-02, Amendment 39-17316 (78 FR 4051, January 18, 2013), and adding the following new AD: The Boeing Company: Docket No. FAA-2017-0905; Product Identifier 2017-NM-090-AD. (a) Comments Due Date We must receive comments by November 20, 2017. (b) Affected ADs This AD replaces AD 2013-01-02, Amendment 39-17316 (78 FR 4051, January 18, 2013) (``AD 2013-01-02'').
