2024-26-09: Time Limits/Maintenance Checks; Flight Controls

1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by: a. Removing Airworthiness Directive (AD) 2021-10-02, Amendment 39-21535 (86 FR 33088, June 24, 2021); and b. Adding the following new AD: 2024-26-09 Bombardier, Inc.: Amendment 39-22924; Docket No. FAA-2024-1483; Project Identifier MCAI-2023-01094-T. (a) Effective Date This airworthiness directive (AD) is effective March 11, 2025. (b) Affected ADs This AD replaces AD 2021-10-02, Amendment 39-21535 (86 FR 33088, June 24, 2021) (AD 2021-10-02). (c) Applicability This AD applies to Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes, certificated in any category, having serial numbers 9002 through 60081 inclusive. (d) Subject Air Transport Association (ATA) of America Code 05, Time Limits/Maintenance Checks; 27, Flight Controls. (e) Reason This AD was prompted by a determination that a new airworthiness limitation is necessary. The FAA is issuing this AD to address sand contamination and corrosion of the elevator torque tube bearings, which could lead to binding or seizure of the bearings, and potentially lead to a reduction in or loss of airplane pitch control. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Retained Inspection and Corrective Actions, With Change This paragraph restates the requirements of paragraph (g) of AD 2021-10-02, with a change to table 1 to paragraph (g), which identifies the airplane marketing designation instead of the serial number range, and a change to add an additional source for identifying the date of airplane manufacture. Within 36 months from July 29, 2021 (the effective date of AD 2021-10-02) or within 63 months from the date of airplane manufacture, as identified on the identification data plate of the airplane or in the airplane technical logbook, whichever occurs later: Do a general visual inspection of the left- and right-hand elevator torque tube bearings for any sand, dust, or corrosion; perform a functional test of the elevator control system; and do all applicable corrective actions; in accordance with the Accomplishment Instructions of paragraphs 2.B., 2.C., and 2.D. of the applicable material specified in table 1 to paragraph (g) of this AD. Applicable corrective actions must be done before further flight. Repeat the general visual inspection and functional test thereafter at intervals not to exceed 63 months. Accomplishing the revision of the existing maintenance or inspection program required by paragraph (i) of this AD terminates the requirements of this paragraph. Table 1 to Paragraph (g)-Service Information ER04FE25.000 (h) No Reporting Requirement Although the material identified in table 1 to paragraph (g) of this AD specifies to submit certain information to the manufacturer, this AD does not include that requirement. (i) New Revision of the Existing Maintenance or Inspection Program Within 30 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in the applicable temporary revision identified in table 2 to paragraph (i) of this AD. The initial compliance time for doing the task is at the time specified in the applicable temporary revision identified in table 2 to paragraph (i) of this AD, or within 90 days after the effective date of this AD, whichever occurs later. Accomplishing the revision of the existing maintenance or inspection program required by this paragraph terminates the actions required by paragraph (g) of this AD. Table 2 to Paragraph (i)-Applicable Temporary Revisions ER04FE25.001 (j) New No Alternative Actions or Intervals After the existing maintenance or inspection program has been revised as required by paragraph (i) of this AD, no alternative actions ( e.g., inspections) or intervals may be used unless the actions and intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (l)(1) of this AD. (k) Credit for Previous Actions (1) This paragraph provides credit for actions required by paragraph (g) of this AD, if those actions were performed before July 29, 2021 (the effective date of AD 2021-10-02) using the applicable material specified in paragraphs (k)(1)(i) through (vi) of this AD, which are not incorporated by reference in this AD.
