## Abstract

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by reports of fluid entry and accumulation in the aft equipment bay. This AD requires modifying the aft equipment bay. We are issuing this AD to prevent excessive quantities of flammable fluid accumulation in the aft equipment bay. Flammable fluid entry and accumulation in the aft equipment bay, in excessive quantities, could exceed safe levels maintained by the drainage and ventilation system.
