Start Preamble

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by reports of aileron and rudder control cables which may have tensions that are beyond allowable limits. This proposed AD would require revising the maintenance or inspection program to incorporate certification maintenance requirement tasks that introduce functional tests of the control cable tension. We are proposing this AD to detect and correct out-of-tolerance tension in the control cables, which, with certain system failures and environmental conditions, could result in reduced controllability of the airplane.

DATES:

We must receive comments on this proposed AD by December 22, 2016.

ADDRESSES:

You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:

Discussion

Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF-2016-06R1, dated July 25, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ”the MCAI”), to correct an unsafe condition for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. The MCAI states:

Recent in-service inspections have shown that aileron and rudder control cables may have tensions beyond allowable limits. Review of the technical documentation found that there are no maintenance tasks to detect and rectify out-of-tolerance tensions on these cables. Out of tolerance cables in combinations with certain system failures and environmental conditions could result in the degraded aircraft controllability.

* * * [This Canadian] AD was issued to mandate a revision to the approved maintenance schedule [maintenance or inspection program, as applicable] to introduce cable tension check [e.g., functional test,] as [certification maintenance requirement] tasks.

You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-9304.

This proposed AD would require revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (j)(1) of this proposed AD. The request should include a description of changes to the required actions that will ensure the continued operational safety of the airplane.

Related Service Information Under 1 CFR Part 51

We reviewed the following Bombardier, Inc. service information:

  • Temporary Revision (TR) 5-2-10, dated November 24, 2015, to Part 2, Section 5-10-40, of Bombardier Global Express XRS BD-700 Time Limits/Maintenance Checks.
  • TR 5-2-15, dated November 24, 2015, to Part 2, Section 5-10-40, of Bombardier Global 6000 GL 6000 Time Limits/Maintenance Checks.
  • TR 5-2-15, dated November 24, 2015, to Part 2, Section 5-10-40, of Bombardier Global 5000 GL 5000 Featuring Global Vision Flight Deck—Time Limits/Maintenance Checks.
  • TR 5-2-16, dated November 24, 2015, to Part 2, Section 5-10-40, of Bombardier Global 5000 BD-700 Time Limits/Maintenance Checks.
  • TR 5-2-47, dated November 24, 2015, to Part 2, Section 5-10-40, of Bombardier Global Express BD-700 Time Limits/Maintenance Checks.

The service information identifies airworthiness limitation tasks for functional tests of the cable tension of the aileron and rudder control cables. 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 and Requirements of This AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of these same type designs.

Costs of Compliance

We estimate that this proposed AD affects 60 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-hours × $85 per hour = $85 per airplane$0$85$5,100

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 AD will not have federalism implications under Executive Order 13132. This AD will Start Printed Page 78082not 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 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.

The initial compliance time for doing the tasks is specified in paragraph (h) of this AD. When the applicable temporary revision (TR) has been included in general revisions of the TLMC, the general revisions may be inserted in the maintenance or inspection program, and the applicable TR may be removed, provided the relevant information in the general revision is identical to that in the applicable TR.
