Airworthiness Directive · Amendment 39-18201 · Fuel
Bombardier, Inc. Airplanes
This AD applies to Bombardier, Inc. Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 airplanes, certificated in any category, serial numbers (S/N) 003 through 624 inclusive, and 626.
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 airplanes. This AD was prompted by fuel system reviews conducted by the manufacturer. This AD requires revising the maintenance or inspection program, as applicable, to incorporate new limitations for fuel tank systems. We are issuing this AD to prevent potential ignition sources within the fuel system, which could result in a fuel tank explosion.
Within 30 days after the effective date of this AD, revise the maintenance or inspection program, as applicable, to include fuel system limitation (FSL) Task Numbers FSL-02, “Detailed Inspection of the Fuel Tank Bonding Jumpers”; and FSL-17, “Functional Check of the Fuel Tank Components and the Plumbing Lines Electrical Bonding”; as specified in the applicable service information identified in paragraphs (g)(1) through (g)(5) of this AD. The initial compliance times for accomplishing the tasks are specified in paragraphs (h)(1), (h)(2), and (h)(3) of this AD. Doing this revision terminates the requirements of paragraph (f) of AD 2008-13-09, Amendment 39-15572 (73 FR 47029, August 13, 2008), for Task Numbers FSL-02 and FSL-17 only.
