Number: CF-2007-32R2 Subject: Fuel System Safety - Introduction of Maintenance Tasks Effective: 11 July 2013 Revision: Supersedes Airworthiness Directiv e (AD) CF-2007-32R1, issued 1 March 2013. Applicability: Bombardier Inc. model DHC- 8 102, 103, 106, 201, 202, 301, 311, 314 and 315 aeroplanes, serial numbers 003 through 672. Compliance: As indicated below, unless already accomplished. Background: Bombardier Aerospace has completed a syst em safety review of the aeroplanes fuel system against fuel tank safety standards in troduced in Chapter 525 of the Airworthiness Manual through Notice of Proposed Am endment (NPA) 2002-043. The identified non-compliances were then assessed us ing Transport Canada Policy Letter No. 525- 001, to determine if mandatory corrective action is required. The assessment showed that supplemental maintenance tasks are required to prevent potential ignition sources within the fuel sy stem, which could result in a fuel tank explosion.

Revision 1 of this AD was issued to clarify the phase-in schedule for tasks FSL-02 and FSL-17.
