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.

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.

Bombardier, Inc.: Docket No. FAA-2016-9304; Directorate Identifier 2016-NM-028-AD.
We must receive comments by December 22, 2016.
This AD applies to Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes, certificated in any category, serial numbers 9002 through 9743 inclusive, and 9998.
This AD was prompted by reports of aileron and rudder control cables which may have tensions that are beyond allowable limits. We are issuing 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.
Within 30 days after the effective date of this AD, revise the maintenance or inspection program, as applicable, to incorporate certification maintenance requirement (CMR) tasks 27-11-35-101, 27-11-35-102, and 27-21-27-101 (for functional tests of the control cable tension) as specified in the applicable service information in paragraphs (g)(1) through (g)(5) of this AD. 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.
