Abstract
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 787-8 and 787-9 airplanes. This AD was prompted by a report that the parking brake and alternate pitch trim module (PBM) may unintentionally disengage. This AD requires replacing the PBM and doing a PBM installation test. We are issuing this AD to address the unsafe condition on these products.
