DOORS 

REWORK – PASSENGER DOOR – 

REPLACEMENT OF PAX DOOR TENSATOR SPRINGS 

1. PLANNING INFORMATION 

A. Effectivity 

BD-700-1A11 aircraft, Serial No. 9166, 9249 and 9279 to 9359. 

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 premature failure of the passenger door tensator 

springs. After investigation, it was determined 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 tensator springs thus preventing unexpected 

downtime and maintenance costs.
