Airworthiness Directives; McDonnell Douglas Model DC-8 Series Airplanes

This document corrects and clarifies information in an existing airworthiness directive (AD) that applies to certain McDonnell Douglas Model DC-8 series airplanes. That AD currently requires a revision to the Airplane Flight Manual Supplement to ensure that the main deck cargo door is closed, latched, and locked; repetitive inspections of the wire bundle and door latch rollers to detect damage; and repair or replacement of damaged components. That AD also requires, among other actions, modification of the indication and hydraulic systems of the main deck cargo door, and installation of a means to prevent pressurization to an unsafe level if the main deck cargo door is not closed, latched, and locked. This document corrects two errors that resulted in the incorrect references of two paragraphs. This correction is necessary to prevent opening of the cargo door while the airplane is in flight, and consequent rapid decompression of the airplane including possible loss of the door, flight control, or severe structural damage.
