SPECIAL CHECK/REPLACEMENT – FIRE EXTINGUISHING SYSTEM – INSPECTION OF CHECK TEE, PART NO. 446651



### 1. PLANNING INFORMATION
NOTE : Before performing PART B, make sure your schedule allows a minimum of 24 hours downtime, should a replacem ent check tee fitting be required. A. Effectivity BD-700-1A11 aircraft, Serial No. 9127 to 9383, 9389 to 9400, 9404 to 9431 and 9998

. All other subsequent BD-700-1A11 aircraft are scheduled for the modification in production. NOTE : The instructions given in this Alert Service Bulletin are only applicable to the systems and parts installed at t he time of delivery of the aircraft or as changed by Bombardier Aerospace Service Bulletin(s). Before you do this bulletin, examine all STC, STA or equivalent action changes to make sure that this bulletin can be completed.
B. Reason This Alert Service Bulletin introduces an inspection of the three check tee fittings installed in the engine and APU fire exti nguishing system. It was reported that a check tee fitting was found with two balls insta lled. Only one ball is installed in the body of the check tee fitting. If two balls are installed in the body of the check tee fitting, the flow of the fire extinguishing agent is partially re stricted. This restriction can cause insufficient concentration of fire extinguishing agent necessary to suppress an engine or APU fire.MODEL BD-700-1A11 (BD-700)
