AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 717-200 airplanes; Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40 and DC-10-40F airplanes; Model MD-10-10F and MD-10-30F airplanes; Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) airplanes; Model MD-88 airplanes; and Model MD-90-30 airplanes. This proposed AD was prompted by reports of latent air data transducer degradation. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate special compliance items (SCIs). We are proposing this AD to prevent erroneous air data information, which could lead to a mid-air collision within reduced vertical separation minimum (RVSM) airspace.

DATES:

We must receive comments on this proposed AD by October 27, 2014.

SUPPLEMENTARY INFORMATION:

Comments Invited

We invite you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2014-0624; Directorate Identifier 2014-NM-005-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments.

We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD.

Discussion

We have received reports of latent air data transducer degradation. This condition, if not corrected, could result in erroneous air data information, which could lead to a mid-air collision within reduced vertical separation minimum (RVSM) airspace.

Relevant Service Information

We reviewed the following service information, which describes procedures for doing a functional test of the captain's and first officer's altimeters.

  • Boeing Report No. MDC-02K1003, Trijet Special Compliance Item (SCI) Report 34-4, “Functional Test of the Captain and First Officer's Altimeter,” Revision K, dated February 1, 2013.
  • Boeing Report No. MDC-92K9145, Twinjet SCI Report 34-1—“Functional Test of the Captain and First Officer's Altimeter,” Revision M, dated February 5, 2013.

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 the same type design.

Proposed AD Requirements

This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate special compliance items (SCIs).

This proposed AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by section 91.403(c) of the Federal Aviation Regulations (14 CFR 91.403(c)). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, an operator might not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR Start Printed Page 5467391.403(c), the operator must request approval of an alternative method of compliance (AMOC) in accordance with the provisions of paragraph (i) of this proposed AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane.

Differences Between This Proposed AD and the Service Information

Boeing Report No. MDC-02K1003, Trijet SCI Report 34-4, “Functional Test of the Captain and First Officer's Altimeter,” Revision K, dated February 1, 2013, describes actions that apply to The Boeing Company Model MD-11 and MD-11F airplanes. Based on in-service data, we have determined that rulemaking action is unnecessary at this time for these airplanes. However, we might consider additional rulemaking if further data is received that identifies an unsafe condition on these airplanes.

Costs of Compliance

We estimate that this proposed AD affects 716 airplanes of U.S. registry.

We estimate the following costs to comply with this proposed AD:

Estimated Costs

ActionLabor costParts costCost per productCost on U.S. operators
Maintenance or inspection program revision1 work-hour × $85 per hour = $85$0$85$60,860

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 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.
