## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to all Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes. This action requires determining exposure to runway deicing fluids containing potassium formate, and, for certain airplanes, repetitive inspections of certain electrical connectors in the wheel well of the main landing gear for corrosion, and follow-on actions. This action is necessary to prevent such corrosion, which could result in incorrect functioning of critical airplane systems essential to safe flight and landing of the airplane. This action is intended to address the identified unsafe condition.
