2018-20-20: Flilght Controls

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: [[Page 52143]] 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): 2018-20-20 Bombardier, Inc.: Amendment 39-19454; Docket No. FAA- 2018-0397; Product Identifier 2017-NM-163-AD. (a) Effective Date This AD is effective November 20, 2018. (b) Affected ADs None. (c) Applicability This AD applies to Bombardier, Inc., Model BD-700-1A10 and BD- 700-1A11 airplanes, certificated in any category, serial numbers 9492 through 9711 inclusive, 9713 through 9717 inclusive, 9719 through 9726 inclusive, 9728, 9730, 9732, 9733, 9743, and 9751. (d) Subject Air TransportAssociation (ATA) of America Code 27, Flight controls. (e) Reason This AD was prompted by a report of cracking at the fastener holes of the left-hand-side support bracket of the elevator bell crank for the control linkage in the vertical stabilizer. We are issuing this AD to address any cracking in the support bracket of the elevator bell crank, which could lead to detachment of the bracket and loss of functionality of the elevator on the affected side, and result in reduced controllability of the airplane. Failure of both brackets could result in loss of pitch control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Inspection, Measurement, and Corrective Action Within 60 months after the effective date of this AD, or before accumulating 7,500 total flight cycles, whichever occurs first: Do an eddy current inspection of the support brackets of the elevator bell crank, part number (P/N)GD248-8750-3 and P/N GD248-8750-4, for any cracking at the fastener holes, and do a measurement to confirm that the fastener hole diameters are within tolerance, as applicable, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 700-27-5009, Revision 02, dated June 15, 2018 (for Model BD-700-1A11 airplanes); or Bombardier Service Bulletin 700-27-6009, Revision 01, dated July 18, 2017 (for Model BD-700-1A10 airplanes). If any cracking is found or if any fastener hole is out of tolerance, before further flight, replace with a new support bracket, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 700-27-5009, Revision 02, dated June 15, 2018 (for Model BD-700-1A11 airplanes); or Bombardier Service Bulletin 700-27-6009, Revision 01, dated July 18, 2017 (for Model BD-700-1A10 airplanes).
