Background/Reason:

On the newly inducted B777-300ER aircraft it was found that on the chiller/refrigerator/freezer an error message was displayed continuously and the respective unit had to be replaced. This issue was raised to vendor. B/E Aerospace confirmed that other operators also observed this problem.

B/E Aerospace has issued SB600-1-25-009, Rev 0 to update the software in all chiller/refrigerator/freezer units on affected aircraft by uploading the software via USB tool, provided by B/E Aerospace.

Material Requirement (Vendor B/E Aerospace)

1)     P/N: NYCOTE7-11; Sealant, Coating; Qty A/R

2)     P/N 4012268-001 Revision “H”; USB with Software; Qty 01

3)     Software Loader; Qty 01

4)     P/N 4012629-001; USB Progr. Pod; Qty 01

Accomplishment Instructions

1) Observe all Warnings and Cautions as stated in CMM 25-36-40, Rev 2.

Note:

This instruction is applicable for all seven (7) chiller/refrigerator/freezer installed on affected aircraft on which the software update shall be performed as follows:

• Galley F1 - Compartment 103
• Galley M1 - Compartment 105 and 106
• Galley M5 - Compartment 505 and 506
• Galley A3 - Compartment 308 and 309

Refer to B777 AMM 25-31-00 to pull the applicable C/B from the galley control panel in the respective galley.

2) Remove air filter assy (-10, IPL Fig 1), rear cover (40, IPL Fig 4) and main cover (80) as detailed in DISASSEMBLY section of CMM, as stated in the B/E Aerospace SB600-1-25-009, Rev 0, section 2.B.

NOTE: Although not recommended, rear cover (40) and main cover (80) may remain installed and only air filter assy (-10, IPL Fig 1) be removed to allow access through bezel (230, IPL Fig 4) to perform this Service Bulletin.

3) Disconnect two (2) screws securing receptacle P5 (320, IPL Fig 2) to J5 on PCB (PC3) (450, IPL Fig 5). Remove receptacle P5 (320, IPL Fig 2) from receptacle J5 of PCB (PC3) (450, IPL Fig 5), as stated in the B/E Aerospace SB600-1-25-009, Rev 0, section 2.C.

NOTE: The two (2) screws securing receptacle P5 (320, IPL Fig 2) to J5 will remain attached, as a part of receptacle P5 (320), with one (1) being ground screw lock (E5) (315).

4) Connect USB Programming Pod, PN 4012629-001 to receptacle J5 and USB receptacle to USB port of  Laptop and apply power to Laptop.

Note:

The blue LED of Modified USB Programming Pod will illuminate, indicating power and correct initialization with Laptop.

5) Close C/B which was pulled in accomplishment step #1.

Note:

The yellow LED of Modified USB Programming Pod will illuminate.

6) Install new Software, PN 4012268-001 Revision “H”, as stated in the B/E Aerospace SB600-1-25-009, Rev 0, section 2.G.

7) Remove power to Chiller/Refrigerator/Freezer (-1, IPL Fig 1) and PC (No. 103), as stated in the B/E Aerospace SB600-1-25-009, Rev 0, section 2.H.

8) Disconnect 62 pin receptacle of Modified USB Programming Pod, PN 4012629-001, from J5 and USB receptacle from USB port of PC (No.103), as stated in the B/E Aerospace SB600-1-25-009, Rev 0, section 2.J.

9) Reconnect receptacle P5 (320, IPL Fig 2) to J5 of PCB (PC3) (450, IPL Fig 5). Secure P5 (320, IPL Fig 2) to J5 using the two (2) screws attached to receptacle P5 (320), as stated in the B/E Aerospace SB600-1-25-009, Rev 0, section 2.K.

NOTE: The two (2) screws securing receptacle P5 (320) to receptacle J5 should have remained attached, as a part of receptacle P5 (320), with one (1) being ground screw lock (E5) (315).

10) Verify software installation, as stated in the B/E Aerospace SB600-1-25-009, Rev 0, section 2.L.
