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): 2019-15-09 Bombardier, Inc.: Amendment 39-19702; Docket No. FAA- 2019-0120; Product Identifier 2018-NM-167-AD. (a) Effective Date This AD is effective September 19, 2019. [[Page 41631]] (b) Affected ADs None. (c) Applicability This AD applies to Bombardier, Inc., Model DHC-8-400, -401, and -402 airplanes, certificated in any category, serial numbers (S/Ns) 4001 through 4547 inclusive, having outboard spoiler actuator mounting brackets with part numbers (P/Ns) 85714052-101 or 85714052- 102. (d) Subject Air Transport Association (ATA) of America Code 57, Wings. (e) Reason This AD was prompted by a report of a cracked outboard spoiler actuator mounting bracket. The FAA is issuing this AD to address cracking of the outboard spoiler actuator mounting brackets, which could cause inoperability or jam of a single spoiler panel and possible jam of the aileron circuit. This condition, if not corrected, could adversely affect the continued safe operation and landing of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Repetitive Inspections At the applicable time specified in paragraph (g)(1) or (g)(2) of this AD: Do a general visual inspection for cracks in the left and right outboard spoiler actuator mounting brackets having P/N 85714052-101 or 85714052-102 (belonging to assemblies having P/N 85714018-001 or P/N 85714018-002, respectively), in accordance with Section 3.B, Part A, of the Accomplishment Instructions of Bombardier Service Bulletin 84-27-72, Revision A, dated November 9, 2017. Repeat the inspection thereafter at intervals not to exceed 8,000 flight hours.

(2) For airplanes having 12,000 total flight hours or more as of the effective date of this AD: Within 6,000 flight hours after the effective date of this AD. (h) Part Replacement (1) If, during any inspection required by paragraph (g) of this AD, either the left or right outboard spoiler actuator mounting bracket is found cracked: Before further flight, replace both the left and right brackets with new bracket assemblies having P/N 85714018-003 or P/N 85714018-004, including doing all applicable related investigative actions and corrective actions, in accordance with Section 3.B, Part B, of the Accomplishment Instructions of Bombardier Service Bulletin 84-27-72, Revision A, dated November 9, 2017; except, where the service information specifies contacting Bombardier for corrective action, this AD requires accomplishing the action using a method approved by the Manager, New York ACO Branch, FAA; or Transport Canada Civil Aviation (TCCA); or Bombardier, Inc.'s TCCA Design Approval Organization (DAO). If approved by the DAO, the approval must include the DAO-authorized signature. (2) If, during any inspection required by paragraph (g) of this AD, no cracking is found on the left and right outboard spoiler actuator mounting brackets, and the left and right outboard spoiler actuator mounting brackets have not already been replaced per the requirements of paragraph (h)(1) of this AD: Replace both the left and right brackets with new bracket assemblies having P/N 85714018- 003 or P/N 85714018-004, including doing all applicable related investigative actions and corrective actions, at the applicable time specified in paragraph (h)(2)(i)or (h)(2)(ii) of this AD, in accordance with Section 3.B, Part B, of the Accomplishment Instructions of Bombardier Service Bulletin 84-27-72, Revision A, dated November 9, 2017; except, where the service information specifies contacting Bombardier for corrective action, this AD requires accomplishing the action using a method approved by the Manager, New York ACO Branch, FAA; or TCCA; or Bombardier, Inc.'s TCCA DAO.

(ii) For airplanes that have accumulated 34,000 total flight hours or more as of the effective date of this AD: Replace the outboard spoiler actuator mounting brackets within 6,000flight hours after the effective date of this AD. (i) Terminating Action for Repetitive Inspections Replacement of an outboard spoiler actuator mounting bracket, in accordance with the requirements of paragraph (h) of this AD, is terminating action for the repetitive inspections required by paragraph (g) of this AD for the replaced bracket.
