CONVERSION BETWEEN THE COMBINED PASSENGER/CARGO CONFIGURATIONS
EFFECTIVITY
Passenger/Cargo Convertible Airplanes
1. General
A. The instructions in this section provide general steps, which are necessary to convert the cabin between the various combined passenger/cargo configurations (Fig. 201). These conversions are divided into two types; those, which increase the cargo area of the cabin, and those, which decrease the cargo area of the cabin.
B. Certain operations and conditions must be accomplished when converting the cabin to accommodate cargo. These are summarized as follows:
(1)
Along both sides of any section of the cabin being converted to carry cargo, individual air outlets on passenger service units must be closed, and reading lights switched off.
(2)
When the cabin is in one of the combined passenger/cargo configurations the floor-mounted portable dry-chemical fire extinguisher, and its applicator, must be installed in the forward part of the cabin. Cargo loading in these circumstances must permit an aisle for access between the crew and passenger compartments, and must permit the use of the portable dry-chemical fire extinguisher, with applicator, to effectively reach fires in all areas-of the cargo compartment.
(3)
The main cargo door threshold assembly is installed temporarily, when no other facilities are available, to aid the movement of pallets through the main cargo door opening.
(4)
When the cabin is in one of the cargo carrying configurations a barrier net is installed across the cabin at approximately body station 354.
(5)
The personnel safety net is installed across the main cargo door opening while the door is open to protect personnel working in the cabin. When the main cargo door is closed in a cargo carrying configuration, the safety net is stowed in a bag installed on the sidewall just aft of the cargo door.
(6)
When the seats adjacent to the emergency exits are removed, or installed, the seat armrests attached to the emergency exits should be removed, or installed, with the seats to which they belong.
