Compliance
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Required actions
This paragraph restates the requirements of paragraph (g) of AD 2011-03-13, Amendment 39-16597 (76 FR 6539, February 7, 2011). Except for Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplane, serial number 10002, for airplanes that have accumulated 4,000 or less total flight hours as of March 14, 2011 (the effective date of AD 2011-03-13): Before the accumulation of 6,000 total flight hours, do a detailed inspection of the RTL for broken return springs and damage through the casing, or chafing of the casing of the primary actuator, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 670BA-27-055, Revision A, dated August 6, 2010. Before further flight, replace any broken return springs with new springs, and repair or replace with a new actuator any chafed or damaged primary actuator, as applicable, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 670BA-27-055, Revision A, dated August 6, 2010. Repeat the inspection thereafter at intervals not to exceed 6,000 flight hours. Accomplishment of the actions required by paragraph (j) of this AD terminates the requirements of this paragraph.
Unsafe condition
This AD was prompted by reports of failure of the rudder travel limiter (RTL) return spring. We are issuing this AD to prevent failure of the RTL, which would permit an increase of rudder authority beyond normal structural limits and consequently affect the controllability of the airplane.
Affected ADs
This AD supersedes AD 2011-03-13, Amendment 39-16597 (76 FR 6539, February 7, 2011).
