. NOTE : The instructions given in this Service Bulletin are only applicable to the systems and parts installed at the 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 Operators have reported pr emature failure of the passenger door tensator springs. After investigation, it was det ermined that the spring manufacturer did not adequately heat treat the steel. As a result of this, micro-fracturing and micro-pore formation was noticed on the tensator springs. This can cause failure under cyclic loading prior to the TLMC life limit. There are four tensator springs used to assist and counter balance the weight of the passenger door. These work together with the passenger door actuator to close and control the rate of descent of the door when opening. This Service Bulletin replaces all four t ensator springs thus preventing unexpected downtime and maintenance costs.MODEL BD-700-1A10 (BD-700)
