FAA Revises Airworthiness Directive for Boeing 737-600 to 900ER Series Airplanes

Summary

The Federal Aviation Administration (FAA) is revising an earlier notice of proposed rulemaking (NPRM) for an airworthiness directive (AD) that applies to all Boeing Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes, expanding its applicability to include the 737-900ER model, to prevent increased structural loads on the aft engine mount and potential failure of the aft engine.
