. Accomplishment 0 1 this Service Bulletin consists in installing the new primary lock on 10 th r ust reverser actuation system doors . 

### Selected doo rs. fo r retrofit only. have been shown through fl ight and simu lator tests with significant repercussion in case 

### 01 untimel y deployment dose to the ground. 

### The 10 doors for which this S8 applies are: Outer engines 11 and 4) : all 4 doors of each engine . Inner engines (2 and 3) : upper inboard door of each engine. 

### The new primary lock lever arm bearings are sealed and greased to make sure that contaminat ion can not affect the locking lever arm restor i ng torque . The locking tever arm torque springs have an increased torque value which will improve locking capability. The new primary lock design includes a more robust cam design with improved fatigue behaviour. There is also a new valve spring wh icll provides addit iona l protection against poten tial hydraulic spikes in the reiurn system. In order to help operators 10 manage tile different conf igurations which will follow th is Service Bulletin embodiment. a specific red placard to be installed on each T/R cowl rorward frame, will detail the parts required depending on the thrust · reverser pivoting · door location on the aircraft. For further information. please refer to TFU 78 .30.00.052. Accomplishment of this Service Bulletin and Service Bulle tin 78 - 4038 will i mprove the reliabil ity of the thrust reverser locking mechanism. GENERAL E VALUATIO N**~**
