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, certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
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 AD CF- 2024-35, dated October 16, 2024 (Transport Canada AD CF-2024-35).
Unsafe condition
This AD was prompted by reports that a cockpit voice recorder (CVR) impact switch was installed in the wrong direction. The impact switch disables power to the CVR in the event of an accident to prevent overwriting cockpit recordings. The FAA is issuing this AD to address an incorrectly installed impact switch, which could result in loss of data that could hinder the identification of the unsafe condition in the event of an accident and consequently impede the development of actions to address the unsafe condition that caused the accident.
Affected ADs
None.
