This SAE Aerospace Standard (AS) defines interface configurations for the ground air conditioning service connection on commercial transport aircraft. In addition, it defines the clearances required to accommodate the connection of ground air conditioning hose couplings. Two types of service connections are included. The Type A connection (Figure 1) is a slotted ring with integral locking pads and is comparable to the MS33562 connection. The Type B connection (Figure 2) is a flanged tube with external locking lugs (Figure 3). The Type B connection has the same interface dimensional requirements as the Type A connection.

Purpose:

The purpose of this document is to establish uniform interface configurations on commercial transport aircraft for the ground air conditioning (conditioned air) service connection. Consideration is also given to the durability, maintainability, and repairability of the connection.
