Reproduction or disclosure to third parties of this document or any part thereof, or the use of any information contained therein for purposes other than explicitly allowed by the aforesaid agreement, is not permitted 

except with the prior written permission of Fokker Services B.V.

C. Reason 

(1) A number of Fokker 100 aircraft have been delivered from the production line with a 

Fuel-Balance Transfer-System (FBTS). Other Fokker 100 aircraft were delivered with 

only provisions for the FBTS system. On some of these aircraft the FBTS may have 

been retrospectively activated through Service Bulletin SBF100-28-021. The FBTS 

could be used during maintenance activities to move the Centre of Gravity (CG) 

forward by transferring fuel from the main tanks to the centre tank through the crossfeed system and a Fuel-Balance Transfer-Valve (FBTV). 

(2) In 1994, following a Failure Mode and Effect Analysis (FMEA) a dormant unsafe 

failure mode was discovered , which could lead to fuel starvation and consequently to 

a double engine flame-out. Although the risk of occurrence is remote, it was 

considered a prudent measure to have the FBTS de-activated. Therefore 

recommended Service Bulletins SBF100-28-029 and SBF100-28-030 were issued. 

The CAA-NL issued airworthiness directives to mandate this de-activation. 

(3) Recently, feedback received from the field raised a concern that on some aircraft the 

FBTS may have been re-activated, which is causing non-compliance with Service 

Bulletin SBF100-28-030 and the applicable CAA-NL airworthiness directive. 

(4) This Service Bulletin has been issued to disable the system to a greater extent in 

order to prevent re-occurrence of non-compliance to the deactivation requirements. 

D. Description 

(1) This Service Bulletin tells you how to: 

- Disable the FBTV Control circuit breaker (if applicable) 

- Remove the connector from the FBTS wiring harness (if applicable) 

- Remove the FBTV actuator and install locking device (if applicable) 

- Placard the guarded FBTS switch on the Maintenance and Test Panel (MTP-B). 

E. Compliance 

(1) Recommended. 

Fokker Services recommends the accomplishment of this Service Bulletin within one 

(1) year from the issue date of this Services Butteltin. 

NOTE: It is expected that EASA will issue an Airworthiness Directive (AD) with 

respect to this subject with the same compliance terms. Refer to the EASA 

website for the publication of a Proposed Airworthiness Directive for 

comments. 

F. Approval 

(1) The technical content of this document is approved under the authority of DOA nr. 

EASA.21J.059.
