This SAE Aerospace Standard (AS) provides design criteria and performance tests for crash axes intended for use by
aircraft crew members to assist in evacuation, extrication, fire fighting, or other emergency activities.
1.1 Purpose
The purpose of this AS is to assure minimum standards of functionality and performance for crash axes carried aboard
aircraft for use by crew members in emergency situations.
1.2 Introduction
In the preparation of this document, consideration has been given to the performance of existing equipment as well as
recommendations from flight crew associations, aircraft operators, aircraft manufacturers, and emergency equipment
manufacturers. The primary goal of this AS is to ensure that crash axes will perform adequately in emergency situations.
1.3 Alternative Designs
The specifications and test methods provided herein anticipate a traditional "crash ax" configuration with the striking head
at one end of a handle and other features including a pike, wedge and pry bar. The striking force is applied perpendicular
to the major axis of the handle. These specifications are not intended to limit the design to this traditional configuration.
Other alternative designs having a different configuration or other features may be evaluated and determined to meet this
Aerospace Standard. In evaluating the alternative designs, it shall be demonstrated that the design offers at least an
equivalent level of utility and effectiveness in satisfying the functional performance of ARP5403 on crash axes, as well as
the functional tests of Section 5 of this Aerospace Standard. This evaluation shall consider the flight deck and cabin
emergencies anticipated by each of the specific design features, and it shall ensure that ease of stowage and emergency
use in a confined flight deck space is not compromised.strRefField
