| 99-33171 | Airworthiness Directives; McDonnell Douglas Model DC-8 Series Airplanes | Proposed Rule | This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-8 series airplanes, that 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. This action would require, 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 proposal is prompted by the FAA's determination that certain main deck cargo door systems do not provide an adequate level of safety; the latching and locking mechanisms are not of adequate design to prevent structural deformation in the event of component jamming; and that there is an absence of a means to prevent pressurization to an unsafe level if the main deck cargo door is not closed, latched, and locked. The actions specified by the proposed AD are intended 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. | 1999-12-22 | 1999 | 12 | https://www.federalregister.gov/documents/1999/12/22/99-33171/airworthiness-directives-mcdonnell-douglas-model-dc-8-series-airplanes | https://www.govinfo.gov/content/pkg/FR-1999-12-22/pdf/99-33171.pdf | Transportation Department; Federal Aviation Administration | 492,159 | This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-8 series airplanes, that currently requires a revision to the Airplane Flight Manual Supplement to ensure that the main... |
