| C. | Compliance |
| Category 4 |
| GE recommends that you do this Service Bulletin when the W30 and/or W31 harness is/are exposed. |
| NOTE: |
|
| This Service Bulletin is offered to improve the reliability or performance of your GE product, or to help prevent the occurrence of the event or condition described in this Service Bulletin. If the operator elects not to participate in the bulletin, that decision will be taken into consideration by GE in evaluating future product performance issues that may arise in the operators fleet. |
| D. | Concurrent Requirements |
| None. |
| E. | Reason |
| (1) | Objective: |
| To introduce redesigned brackets and harnesses for the fire detector sensing elements of the GEnx-1B engine and to improve product reliability. |
| (2) | Condition: |
| The current design of the W30 and W31 harnesses have shown distress during revenue service that was due to vibration, wear, and assembly/shipping damage which then has lead to the replacement of the harnesses. |
| (3) | Cause: |
| The harness distress has been attributed to multiple causes including: detector terminal positioning, harness pigtail positioning, as well as harness pigtail breakout locations, and unsupported length. |
| (4) | Improvement: |
| The new design of the harnesses and brackets addresses the causes of distress and improves the reliability of the W30 and W31 harnesses. |
| (5) | Substantiation: |
| Substantiation is by analysis and comparative analysis. |
| F. | Approval |
| The data contained in this Service Bulletin has been reviewed by the appropriate governmental authority and the repair(s) and modification(s) herein comply with the applicable Aviation Regulations and are APPROVED for installation in the model(s) listed in this Service Bulletin. |
| G. | Manpower |
| After you get access to the W30 and W31 harnesses, you will need approximately 8.0 man-hours for each engine. |
| H. | Weight and Balance |
| The complete compliance with this Service Bulletin increases weight by 1.50 lb (0.68 kg). |
