Formerly Smiths Aerospace 

TO: ALL HOLDERS OF SERVICE BULLETIN 6200ELM-24-616, 

DATED 9th May 2003. 

FROM: GE AVIATION SYSTEMS LTD

On May 4th 2007 the Aerospace business of Smiths Group, formally known as 

Smiths Aerospace Ltd, was sold to General Electric Corporation and became GE 

Aviation Systems Ltd, doing business as GE Aviation.

This page transmits Revision No. 1 to Service Bulletin 6200ELM-24-616. Revision No. 1 replaces Service 

Bulletin 6200ELM-24-616, dated 9th May 2003 in its entirety. 

This revision corrects the omission of circuit diagrams for those operators whose panels have had service 

bulletin 6202ELM6-24-359 incorporated. As a result of this work the layout of the 115V AC Right Section 1 Bus 

differs from that presented at Figure 2 (Before Conversion) and 3 (After Conversion). To accommodate these 

panels Figures 2A and 3A have been introduced and text added as applicable. 

NOTE: Operators whose panels have had service bulletin 6202ELM6-24-359 incorporated who carried out the 

work affected by the errors referred to above will need to carry out the procedure again to ensure their 

panels are to the correct standard. 

Changed material is indicated with revision bars.

B. Concurrent Requirements

This bulletin is one of a number that detail the work required to be embodied on the P210 

panel to accommodate Flight Deck Switch circuitry. This Service Bulletin should be carried 

out after Service Bulletins 6000ELM-24-555, 6000ELM-24-456, 6000ELM-24-545 and 

6000ELM-24-624. 

C. Reason 

(1) Condition Conversion corrects

The P210 ELMS panel is unable to accommodate the Cabin Telecommunication Unit 

(CTU), and the P210 Passenger Telecommunication System as required by the Flight 

Switch Circuitry. 

(2) Extent condition encountered

Panels 6215ELM2 and 6218ELM3. 

(3) Expected benefits of conversion

The P210 ELMS panel complies with the requirement to accommodate the CTU and 

P210 Passenger Telecommunication System as required by the Flight Deck Switch 

circuitry. 

D. Description

This work requires the removal of three busbars and busbar connections at Circuit Breakers 

C6 (C23430 – CTU) and D3/E5 (C23432/C23434 P210 Passenger Telecommunication 

System). These three Circuit Breakers are then connected to another supply via the contacts 

of an existing relay K24302. Four new busbars are fitted and the busbar connections removed 

earlier are then reconnected. One new wire and four new Flexible Cable Assemblies are 

introduced as a result of this work. Figures 2 to 4 refer. 

E. Compliance

ELMS P210 Right Power Management Panels as defined in BCAG Service Bulletin Number 

777-24-0077. 

F. Approval

The repairs and modifications herein comply with the applicable regulations and are on record 

with the supplier as FAA approved, as well as EASA/JAA approved. 

G. Manpower

The incorporation of this work will take approximately 4 man hours excluding testing.

(a) Work Carried Out Label marked S.B. 6200ELM-24-616, part number 

ELM139-13. 

(38) Locate the Flight Deck Switch Work Carried Out Record Card which should be fixed 

prominently to the Cabinet frame. Fit the new Work Carried Out Label in the next

of previous work. 

NOTE: Operators should note that if, after the completion of this work, they plan to 

incorporate another Flight Deck Switch (FDS) Service Bulletin. They may ignore the 

following paragraphs requiring them to secure those parts of the panel, which have 

been disturbed. This is intended to avoid having to secure, for example, a cableform 

that may subsequently be used in another FDS Service Bulletin. However, this must 

be done at the tradesman’s discretion with full consideration given to the security of 

certain connectors/nuts/screws and the possibility that they may be missed when the 

final FDS Service Bulletin is incorporated. 

(39) Ensure that: 

(a) All disturbed cable clamp pillar screws are torque loaded to between 35.1 and 

42.9 lbf inches (4.0 and 4.8 Nm). 

(b) All disturbed circuit breakers are closed. 

(c) All disturbed nuts and screws are tightened to relevant torque settings. 

(d) All disturbed connectors are reassembled as necessary and reconnected. 

(e) All cables and splices are securely tied-in to suitable positions. 

(f) A full internal cabinet visual inspection is carried out and all debris is 

removed. 

(40) Return the LH Relay Tray to the upright position and secure the 2-off fasteners. 

(41) Return the RH Relay Tray to the upright position and secure the 2-off fasteners. 

(42) Disengage the RH Door Stay and close the RH Door. Secure the 2-off fasteners on 

the RH Door. 

(43) Disengage the LH Door Stay and close the LH Door. Secure the 4-off fasteners on 

the LH Door. 

(44) Apply 'tamperproof' inspection seals to the LH and RH Doors as required from 

customers own resources.
