The FAA's summary their words, unchanged

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes; Model CL-600-2D15 (Regional Jet Series 705) airplanes; Model CL-600-2D24 (Regional Jet Series 900) airplanes; and Model CL- 600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by reports of damage to the protective coating and corrosion on the piston/axle of the main landing gear (MLG), caused by friction between the inboard axle sleeve and the axle thrust face. This AD requires revising the maintenance or inspection program, as applicable, to incorporate a detailed inspection of the MLG piston/axle for damage to the protective coating and for corrosion. We are issuing this AD to address the unsafe condition on these products.

Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: 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 adding the following new airworthiness directive (AD): 2018-22-12 Bombardier, Inc: Amendment 39-19485; Docket No. FAA-2018- 0551; Product Identifier 2018-NM-023-AD. (a) Effective Date This AD is effective December 12, 2018. (b) Affected ADs None. (c) Applicability This AD applies to Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, serial numbers 10002 and subsequent; Model CL-600-2D15 (Regional Jet Series 705) airplanes and Model CL-600-2D24 (Regional Jet Series 900) airplanes, serial numbers 15001 and subsequent; and Model CL-600-2E25 (Regional Jet Series 1000) airplanes, serial numbers 19001 and subsequent; certificated in any category. (d) Subject Air Transport Association (ATA) of America Code 32, Landing gear. (e) Reason This AD was prompted by reports of damage to the protective coating and corrosion found on the piston/axle of the main landing gear (MLG), caused by friction between the inboard axle sleeve and the axle thrust face. We are issuing this AD to address such damage, which could cause the axle to separate from the piston/axle, and ultimately lead to collapse of the landing gear during ground maneuvers or upon landing. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Maintenance or Inspection Program Revision Within 30 days after the effective date of this AD: Revise the maintenance or inspection program, as applicable, by incorporating CRJ Series Regional Jet Temporary Revision (TR) MRB-0059, dated March 20, 2015.The applicable maintenance or inspection program revision required by this paragraph may be done by inserting a copy of CRJ Series Regional Jet TR MRB-0059, dated March 20, 2015, into the maintenance requirements manual (MRM). When the information in CRJ Series Regional Jet TR MRB-0059, dated March 20, 2015, has been included in the general revisions of the MRM, the general revisions may be inserted in the MRM, and this TR may be removed, provided the relevant information in the general revision is identical to that in CRJ Series Regional Jet TR MRB-0059, dated March 20, 2015. The initial time for the task is at the applicable time specified in figure 1 to paragraphs (g) and (h) of this AD.
