Abstract
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD was prompted by reports of electrical shorts of the motor stator wiring burning a hole through the housing of the motor of the cabin air compressor (CAC). This AD requires installing modified inboard and outboard CAC modules on the left-hand (LH) side and right-hand (RH) side cabin air conditioning and temperature control system (CACTCS) packs. We are issuing this AD to prevent the unsafe condition on these products.
