    Problem: With reference to latest update on Honeywell brake Delines issue, it is mentioned that SB will be released in Feb-2018, therefore due to the fact that operator will be affected with the SB as we operate 9 B737NG fleet fitted with Honeywell brakes. We would like to clarify following: 
    1. The compliance of the SB (optional/recommended or mandatory) 
    2. Honeywell strategic support to the operators for the modified heat sinks. 
    3. Cost impact. 
    4. PN’s change on for the below materials.? Can we return the current stock of rotors and pad’s to be embodied. 
    5. After SB embodiment can our workshops revert back to the initial wear pin indicator setting. 

    Knowing that we normally order the following materials of current heat sink: 
    1. Rotors 2612555-700/-660/-620 
    2. Rivit’s 2608438-1/-3 
    3. Brake pads (lining): 357692, 357621, 357690, 357656, 357625, 357691
