Airworthiness Directive · Amendment 39-22209 · Landing gear
MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
This AD applies to all MHI RJ Aviation ULC airplanes identified in paragraphs (c)(1) through (5) of this AD, certificated in any category.
(1) Model CL-600-2C10 (Regional Jet Series 700, 701, & 702).
(2) Model CL-600-2C11 (Regional Jet Series 550).
(3) Model CL-600-2D15 (Regional Jet Series 705).
(4) Model CL-600-2D24 (Regional Jet Series 900).
(5) Model CL-600-2E25 (Regional Jet Series 1000) airplanes.
The FAA is adopting a new airworthiness directive (AD) for all MHI RJ Aviation ULC Model CL-600-2C10 (Regional Jet Series 700, 701 & 702); CL-600-2C11 (Regional Jet Series 550); CL-600-2D15 (Regional Jet Series 705); CL-600-2D24 (Regional Jet Series 900); and CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by reports that the landing gear age of certain airplanes was higher than expected for gear overhaul, which could increase the risk of corrosion. This AD requires verifying the calendar age of the nose landing gear (NLG) and main landing gear (MLG) by way of component maintenance documents, and performing corrective actions if necessary. This AD also prohibits installing certain components. The FAA is issuing this AD to address the unsafe condition on these products.
Within 90 days after the effective date of this AD: Verify the airplane and/or the airplane technical records to determine whether any MLG and NLG components are affected components based on their calendar age, in accordance with Section 2, Part A, of the Accomplishment Instructions of MHI RJ Service Bulletin (SB) 670BA-32-062, Revision A, dated December 2, 2021.
(1) Within the applicable compliance time indicated in figure 1 to paragraph (h) of this AD: Remove the affected NLG components identified in paragraph (g) of this AD in accordance with Section 2, Part B, of the Accomplishment Instructions of MHI RJ SB 670BA-32-062, Revision A, dated December 2, 2021.
(2) Before further flight after removal of the affected components, replace the removed components with serviceable components, in accordance with Section 2, Part D, of the Accomplishment Instructions of MHI RJ SB 670BA-32-062, Revision A, dated December 2, 2021.
(1) Within the applicable compliance time indicated in figure 1 to paragraph (h) of this AD: Remove the affected MLG components identified in paragraph (g) of this AD in accordance with Section 2, Part E or H, as applicable, of the Accomplishment Instructions of MHI RJ SB 670BA-32-062, Revision A, dated December 2, 2021.
(2) Before further flight after removing the affected components, replace the removed components with serviceable components, in accordance with Section 2, Part G or J, as applicable, of the Accomplishment Instructions of MHI RJ SB 670BA-32-062, Revision A, dated December 2, 2021.
(1) As of the effective date of this AD, no person may install, on any airplane, any MLG or NLG component with a calendar age of 12 years or more unless it has been overhauled in accordance with Section 2, Part C, F, or I, as applicable, of the Accomplishment Instructions of MHI RJ SB 670BA-32-062, Revision A, dated December 2, 2021.
(2) As of the effective date of this AD, any MLG or NLG component with a calendar age of less than 12 years may be installed on any airplane, provided it is overhauled in accordance with Section 2 Part C, F, or I, as applicable, of the Accomplishment Instructions of MHI RJ SB 670BA-32-062, Revision A, dated December 2, 2021, prior to reaching 12 years' component calendar age.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
