PDOS Provisioned Engines for MDOS Operation Only - 767 CF6-80C
Overview
Introduction
The CF6-80C engines on the 767 have two different versions of door opening systems that open the thrust reverser halves for access to the engine during maintenance.
- Power Door Opening System (PDOS) with thrust reverser power opening pack connected to aircraft power operated with a switch on the thrust reverser.
- Manual Door Opening System (MDOS) with thrust reverser handpump quick release connector.
This change is done to prepare installation of engines with PDOS system on aircraft that is not provisioned for PDOS system, therefore the MDOS procedure can only be used for opening and closing of the thrust reversers halves for maintenance access.
