What to do
Operators must amend their Transport Canada approved maintenance schedules to include task number 251700-202, a functional check of the flight compartment door decompression latches as detailed in the Maintenance Requirements Manual Part 1, Revision 18 or later approved revisions. This action must be completed within 30 days from the effective date of 14 June 2019 unless already accomplished.
Summary
Airworthiness Directive CF-2019-20R1 is issued by Transport Canada and applies to Bombardier Inc. model CL-600-2C10, CL-600-2D15, CL-600-2D24, and CL-600-2E25 aircraft. This directive addresses the incorrect installation of cockpit door edge protection plates on the upper decompression panel, which could prevent the panel from opening during rapid decompression. The directive mandates maintenance schedule updates to ensure the decompression panel functions correctly.
What changed
This revision corrects the Maintenance Requirements Manual revision number referenced in the corrective actions section. It supersedes the original AD CF-2019-20 issued on 14 May 2019 and clarifies the maintenance task required to verify the decompression panel's free movement.
Why it matters
Ensuring the decompression panel on the flight compartment door operates correctly is critical for maintaining cockpit pressure integrity during rapid decompression events. Failure to comply could compromise the structural integrity between the cockpit and passenger cabin, posing safety risks. Operators and maintenance teams must verify compliance to avoid operational restrictions and ensure airworthiness.
