Description Group 1:
1. CONCURRENT REQUIREMENTS None.
2. BACKGROUND This service bulletin provides instructions to install new outboard leading edge slat skew detection mechanism assemblies (DMAs). Several failures of the proximity sensor within the slat skew DMA have occurred leading to slats up landing events. It was determined that the failed sensors had broken magnet wires. The wires broke due to stresses induced by thermal expansion and contraction of an epoxy applied around them. The new sensors incorporate a new design that isolates the wires from the epoxy used inside the sensor. If the changes in this service bulletin are not done, the sensors may fail and slats may not extend, which could lead to reduced controllability of the airplane during landing.
Boeing Service Related Problem (SRP) 787 SRP-27-0248 is related to this service bulletin.
