This AD was prompted by reports of freezing damage to the Firex discharge pipes and wye assembly of the number 2 engine, and one report of a level 1 ENG FIRE AGENT LO alert during flight. We are issuing this AD to prevent accumulation of water in the discharge pipes and possible consequent freezing damage to the discharge pipes and wye assembly, which could lead to failure of the fire extinguishing system during a fire in the number 2 engine.
