Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Gulfstream Aerospace LP Model Galaxy and Model Gulfstream 200 airplanes. This proposal would require a one-time detailed inspection of the wing flap actuators for proper bonding of the flap actuator fairings to the lower skin of the wings, and related corrective or preventative actions. These actions are necessary to prevent possible damage to adjacent structural elements (such as the horizontal stabilizer) caused by separation of the flap actuator fairings from the wing lower skin, which could result in reduced controllability of the airplane. These actions are intended to address the identified unsafe condition.
