ELECTRICAL POWER

General - A one-time Inspection and Adjustment of the Torque Values on the Circuit 

Breakers, Contactors and Terminal Blocks in the EPC and Battery Relay Panel. 

1. Planning Information

A. Effectivity 

(1) F28 Mark 0070/0100 aircraft serial numbers: 

11244 thru 11585 

(2) Production version of this modification: Not applicable. 

B. Concurrent Requirements 

(1) Before you do this SB, you must do, if applicable: 

- SBF100-24-032 - ELECTRICAL POWER – DC Bus Transfer – The Modification to 

the DC Bus Transfer System. 

(2) Before you do this SB, you must do, if applicable: 

- SBF100-24-041 - ELECTRICAL POWER – AC Bus Transfer – Introduction of SelfLocking Nuts on the Terminal Posts of Electrical Power Contactor pn SG02206. 

NOTE: Disregard the associated Manual Change Notification MCNM F100-120. 

C. Reason 

(1) Fokker Services received reports about loose nuts of contactors in the Electrical 

Power Center (EPC). In some cases this led to damaged (burned) contactors. 

(2) In the past SBF100-24-011 (Alert SB) was issued to inspect and adjust several 

torque values of bus bars and contactors in the EPC and Battery Relay Panel.

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

(3) In the POST SBF100-24-A011 configuration, still loose nuts are found on contactors 

in the EPC, which cause damaged and/or burned contactors. For that reason, a onetime inspection on torque values on nuts for electrical connections in the EPC and 

Battery Relay Panel must be done. Furthermore, new lock washers and certain new 

self locking nuts must be installed. 

Reason for Revision: 

This revision is made to: 

- Incorporate SBCN /01 and SBCN /02 

- Add Terminal Block TB4906A to table 6 on page 16. 

D. Description 

(1) This Service Bulletin is divided into two parts as follows: 

Part 1: Inspection and Adjustment of the Torque Values for the Fokker 100 Aircraft. 

This Part tells you how to: 

- Inspect and adjust the torque values of: 

 - Circuit breakers 

- Fuse holder 

- Relays and contactors 

- Terminal blocks 

- Replace installed lock washers and certain self locking nuts. 

- Use the torque inspection lacquer to seal the nuts. 

Part 2: Inspection and Adjustment of the Torque Values for the Fokker 70 Aircraft. 

This Part tells you how to: 

- Inspect and adjust the torque values of: 

 - Circuit breakers 

- Fuse holder 

- Relays and contactors. 

- Terminal blocks 

- Replace installed lock washers and certain self locking nuts. 

- Use the torque inspection lacquer to seal the nuts. 

Part 3: Completion and Testing for the Fokker 100 and Fokker 70 Aircraft. 

This Part tells you how to: 

- Complete the job. 

- Perform the applicable testing.

3. Accomplishment Instructions

General 

- Obey the warnings, cautions and safety instructions in the procedures we refer you to. 

- In case of conflict between the torque values mentioned in AMM task 20-12-00-910-822-A 

 and D and/or 20-13-00-400-812-A and this service bulletin the latter shall govern. 

- When for an equipment number two different part numbers are given, apply the torque 

 value for the installed part number. 

- Inspect and adjust one contact at a time. 

- Use a suitable calibrated torque wrench to apply the correct torque. 

- When the required material column shows none, inspect and torque the nut or screw as 

follows: 

• Inspect the contact for corrosion, erosion, decontamination, etc. 

• If torque inspection lacquer is present, clean the thread of the stud. 

• Loosen the screw or nut two turns. 

• Torque the nut to the value given in the Table. 

• Apply the torque inspection lacquer. 

NOTE: For the heatsinks only a visual inspection is required as indicated in the Table. 

- When the required material column shows required materials, inspect and torque the nut as 

follows: 

• Inspect the contact for corrosion, erosion, decontamination, etc. 

• Remove and discard the lock washer or self-locking nut. 

• If torque inspection lacquer is present, clean the thread of the stud and the normal nut 

if the nut is re-used. 

• Use a new lock washer or new self-locking nut as given in the Table. 

• Torque the nut to the value given in the Table.
