Reason The circuit to power the completion cente r-installed drain mast heaters is part of the STC for the completed aircraft. Some completion centers used the logic of the HBMU to control the line voltage of the drain mast heaters. These voltages are 28 V dc when the aircraft is on ground, and 115 V ac when the aircraft is airborne. However, this is the same logic circuit t hat controls the line voltage for the pitot 2 heater. By design, the HBMU provides (i) automatic control of power to the pitot 2 heater, (ii) monitors the power to this heater and (iii) shows failure warning messages related to this heater on the Engine Instrument and Crew Alerting System (EICAS). The pitot 2 heater failure EICAS message PITOT 2 HT FAIL shows when the current draw is less that 0.040 A ac. Si nce the completion center-installed drain mast heaters are connected in parallel wit h the pitot 2 heater circuit, a pitot 2 heater failure may not be detected by the built-in monitoring function of the HBMU (masked EICAS failure message). This Service Bulletin removes the completion center-installed drain mast heater wiring from the HBMU and installs new wiring from the LEGCU. Some operators have had 115 V ac applied to the drain mast heaters of their aircraft on the ground. To solve this problem, this Service Bulletin introduces a new WOW logic. C. Description This Service Bulletin gives instructions to:

–Get access to the avionics compartment,

–Do a wiring modification, and

–Do the necessary tests to make sure that the system operates correctly.MODEL BD-700-1A10 (BD-700)

NOTE : This Service Bulletin will be subject to an Airworthiness Directive (AD) to be issued by Transport Canada. E. Approval The technical content of this Service Bulletin has been approved under the authority of Transport Canada Civil Av iation (TCCA) Design Approval STC SA12-31, Federal Aviation Administration (FAA) Design Approval ST03149NY and European Aviation Safety Agency (EASA) Design Approval STC 10040722. F. Manpower NOTES : 1. The man-hours given are estimates to help you schedule the tasks given in this bulletin. The estimate s are for direct labor performed by an experienced crew and do not include the time for familiarization, planning, aircraft preparation in hangar such as towing and positioning of scaffolds, removal of interior furnishings, repainting, supervision and inspection. For more information related to t he manpower estimates, refer to SB 700-00-002. 2. This Service Bulletin may require consumable materials that have specific curing times (refer to Pa ragraph 3). The accumulated curing time is not included in the labor estimates and should be considered for planning purposes before you schedule this Service Bulletin. 3. Labor hours are based on the fact that the modification will be done at the next scheduled maintenance task or “C” check. Therefore no man-hours are allotted to prepare t he aircraft for maintenance or to prepare for this Service Bulletin. The labor necessary to get access for this Service Bulletin may vary from aircraft to aircraft because of the different completions configurations. 35 man-hours are necessary to do this modification. 10 man-hours are necessary to do the retroactive action, if necessary. The labor required to do this Service Bulletin is at no cost if: (i) the work is done at Bombardier Business Aviation Services (BBAS) or Authorized Service Facilities (ASF), and (ii) this Service Bulletin is scheduled at the next “C” check or in less than 15 months from its release date (Basic Issue).MODEL BD-700-1A10 (BD-700)
