The FAA is adopting a new airworthiness directive (AD) for certain MHI RJ 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 a report of a passenger seat Y-belt (lap belt) re-installed in the wrong orientation, due to an incorrect maintenance manual. This AD requires inspecting certain Y-belts for correct installation and damage and corrective actions if necessary. This AD also prohibits the use of certain revisions of a maintenance task. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Within 24 months after the effective date of this AD, inspect each Y-belt for correct installation and damage and, if any incorrect installation or damage is found, within 24 months after the effective date of this AD, do all applicable corrective actions, in accordance with paragraph B, “Procedure,” of the Accomplishment Instructions of MHI RJ Service Bulletin 670BA-25-135, Revision B, dated November 25, 2022. For this AD, damage includes dents or misshapen hooks that attach the belt to the seat.
Note 1 to paragraph (g): Y-belts are also known as lap belts.
Where paragraph B, “Procedure,” of the Accomplishment Instructions of MHI RJ Service Bulletin 670BA-25-135, Revision B, dated November 25, 2022, specifies to “refer to AMM” replace those words with “in accordance with AMM.”
As of the effective date of this AD, it is prohibited to use MHI RJ Aviation ULC Aircraft Maintenance Manual (AMM) task 25-21-04-400-801, revision 69 or earlier.
