2. This Service Bulletin is also applicable for the auxiliary hydraulic system accumulators in the operator’s stock room with Part No. 900095-1 which do not have the letter “E” as part of the suffix stamped on the serial number plate.
A. Effectivity BD-100-1A10 aircraft, Serial No. 20003 to 20335.
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.
MODEL BD-100-1A10 (CL-300) Basic Issue: Dec 16/2010 100-29-14 Page 2 of 9 B. Reason Field evidence has shown from the Regional Jet family that the screw caps of the accumulator are susceptible to cracking after 3500 flight cycles. This could possibly lead to a screw cap release, which in turn may cause damage to the aircraft structure and/or systems.
This Service Bulletin gives instructions to inspect and if required, replace the accumulator in accordance with the compliance given in Paragraph 1.D. with a new or repaired unit with the same part number that has the letter “E” as part of the suffix stamped on the serial number plate.
C. Description This Service Bulletin gives instructions to:
– Get access to the auxiliary hydraulic system, – Inspect the accumulator to determine:
– If the accumulator must be replaced, or – If the accumulator requires identification.
– If the unit must be replaced, remove the accumulator, – Return the removed accumulator for a new or repaired unit, – Install the new or repaired accumulator, and – Do the necessary tests to make sure the system operates correctly.
D. Compliance For accumulators that have less than 3150 flight cycles at the release date of this Service Bulletin, replace the accumulator before 3500 flight cycles.
For accumulators that have more than 3150 flight cycles at the release date of this Service Bulletin, replace the accumulator within the next 350 flight cycles.
For accumulators where the flight cycles are unknown and accumulators that have been replaced and history of replaced hydraulic accumulators is unknown at the release date of this Service Bulletin, replace the accumulator within the next 350 flight cycles.
NOTE: Due to a limited quantity of spare accumulators, we strongly suggest that the Service Bulletin be accomplished only at the due cycle.
E. Approval The technical content of this Service Bulletin has been approved under the authority of Transport Canada Civil Aviation (TCCA) Design Approval Organization (DAO) No. DAO #93-Q-02.
NOTES: 1. The technical content of this Service Bulletin is accepted by the FAA under the Canada/USA bilateral Aviation Safety Agreement.
