Airworthiness Directive · Amendment 39-21790 · Fuselage
Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
This AD applies to all Airbus Canada Limited Partnership (type certificate previously held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Model BD-500-1A10 and BD-500-1A11 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. This AD was prompted by a report of cracking in certain components on left and right sides of the aft wing-to-body fairing (WTBF) structure near the tie-rod attachment at a certain fuselage station; this cracking likely resulted from excessive tie-rod preload. This AD requires inspecting the aft WTBF structure for any cracking or damage, adjusting the load on the two tie-rods at a certain fuselage station, and repair if necessary, as specified in two Transport Canada Civil Aviation (TCCA) ADs, which are incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, Transport Canada Civil Aviation (TCCA) AD CF-2020-32, dated September 25, 2020 (TCCA AD CF-2020-32); or TCCA AD CF-2020-32R1, dated April 23, 2021 (TCCA AD CF-2020-32R1).
(1) Where TCCA AD CF-2020-32 and TCCA AD CF-2020-32R1 refer to its effective date, this AD requires using the effective date of this AD.
(2) Where TCCA AD CF-2020-32R1 refers to the effective date of TCCA AD CF-2020-32 (October 9, 2020), this AD requires using the effective date of this AD.
(3) Where paragraphs B. and E. of TCCA AD CF-2020-32 and Part II and V of TCCA AD CF-2020-32R1 specify to repair “any cracks or damage” at certain compliance times or intervals, this AD requires repairing any cracks or damage before further flight.
(4) Where TCCA AD CF-2020-32 and TCCA AD CF-2020-32R1 refer to hours air time, this AD requires using flight hours.
(5) Where table 1 of TCCA AD CF-2020-32 specifies a compliance time “for new aeroplanes with an aeroplane date of manufacture, as identified on the identification plate of the aeroplane, dated on or after the effective date of this AD” and table 1 of TCCA AD CF-2020-32R1 specifies a compliance time “for new aeroplanes with an aeroplane date of manufacture, as identified on the identification plate of the aeroplane, dated on or after the effective date of AD CF-2020-32 (9 October 2020),” for this AD use “for airplanes with a date of manufacture, as identified on the identification plate of the airplane, dated on or after the effective date of this AD.”
(6) Where TCCA AD CF-2020-32 and TCCA AD CF-2020-32R1 define the “applicable [aircraft maintenance publication] AMP [data module] DM,” replace the text “Airbus Canada Limited Partnership AMP DM BD500-A-J53-82-55-04AAA-720A-A (Aft fairing strut, Wing To Body Fairing (WTBF)—Install procedure) Issue 006, dated 26 June 2020, or later revisions,” with the “Airbus Canada Limited Partnership AMP DM BD500-A-J53-82-55-04AAA-720A-A (Aft fairing strut, Wing To Body Fairing (WTBF)—Install procedure) Issue 006, dated 26 June 2020; or later revisions approved by the Manager, New York ACO Branch, FAA, or TCCA, or Airbus Canada's TCCA Design Approval Organization (DAO). If approved by the DAO, the approval must include the DAO-authorized signature.”
(7) Paragraph D. of TCCA AD CF-2020-32 and Part IV of TCCA AD CF-2020-32R1 specify to report inspection results to Airbus Canada Limited Partnership within a certain compliance time. For this AD, report inspection results at the applicable time specified in paragraph (h)(7)(i) or (ii) of this AD.
(i) If the inspection was done on or after the effective date of this AD: Submit the report within 30 days after the inspection.
(ii) If the inspection was done before the effective date of this AD: Submit the report within 30 days after the effective date of this AD.
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, New York ACO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or responsible Flight Standards Office, as appropriate. If sending information directly to the manager of the certification office, send it to ATTN: Program Manager, Continuing Operational Safety, FAA, New York ACO Branch, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; telephone 516-228-7300; tax 516-794-5531.
