B. Reason 

The circuit to power the completion center-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 that 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. Since the completion center-installed drain 

mast heaters are connected in parallel with 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.

Basic Issue: Aug 28/2012 700-30-021

Revision 01: Nov 21/2012 Page 8 of 17 

D. Compliance 

Recommended at the next “C” check, or within 15 months of release of this 

Service Bulletin (Basic Issue), whichever comes first. 

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 Aviation (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 estimates 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 the manpower estimates, refer to 

SB 700-00-002. 

2. This Service Bulletin may require consumable materials that have 

specific curing times (refer to Paragraph 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 the 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).

G. Material - Cost and Availability 

No kit is necessary to do this modification. For parts and material necessary to do 

this Service Bulletin, refer to Paragraph 3. 

The parts are available at no cost if a no-charge purchase order is sent to 

Bombardier Aerospace at the next “C” check or in less than 15 months from this 

Service Bulletin release date (Basic Issue). 

During or after the above free period, Smart Parts Plus does not pay for the parts.
