What to do

Operators of affected Bombardier CL-600 series aeroplanes must perform initial and repetitive inspections of the window louver panel assemblies and blowout panels according to the specified Bombardier Service Bulletins and Maintenance Requirements Manual tasks. Maintenance schedules must be amended within 30 days of the directive's effective date to incorporate the new inspection tasks. Inspections must be conducted within specified air time intervals, with corrective actions taken as required to maintain compliance.

Summary

Airworthiness Directive CF-2015-28R2 addresses damaged decompression window louver panel assemblies and detached blowout panels on Bombardier Inc. aeroplanes, specifically models CL-600-2B19, CL-600-2C10, CL-600-2D15, CL-600-2D24, and CL-600-2E25 configured with a Class C Cargo Compartment. This directive mandates inspections and corrective actions to ensure the integrity of cargo compartment components that are critical for smoke detection and fire suppression. The directive updates maintenance requirements to prevent uncontrolled cargo compartment fires.

What changed

CF-2015-28R2 revises previous inspection intervals and introduces terminating actions by incorporating new tasks from the revised Bombardier Maintenance Requirements Manual. It supersedes the earlier AD CF-2015-28R1 by replacing repetitive inspections with updated maintenance tasks that extend inspection intervals to 880 hours air time. The directive also adds specific maintenance schedule amendments and allows compliance through approved later revisions.

Why it matters

This directive is crucial for operators and maintenance organizations to prevent safety risks associated with damaged or detached decompression window louver panels and blowout panels, which could compromise cargo compartment fire detection and suppression. Compliance ensures continued airworthiness and regulatory adherence, reducing the risk of uncontrolled fires in the cargo area. It also provides a clear framework for maintenance scheduling and corrective actions, aiding compliance teams in managing inspection programs effectively.
