These changes include additions, deletions, or reconfiguration of hardware and material substitutions, software revisions, and any repair or replacement not authorized in the technical manual. b. Operation of carry-on equipment with a mission requirement for operation in-flight will be assessed for airworthi- ness impact. Airworthiness impact occurs when operation of that equipment can measurably affect the airworthiness of the aircraft system, subsystem or allied equipment.
These include— (1) Operation of carry-on equipment that energizes emission of electromagnetic energy that can affect any aircraft, subsystem or allied equipment controls, indicators, displays, or the navigational system effectiveness. (2) Operation of carry-on equipment that emits light or sound energy that can raise air crew station noise levels, or distract and degrade air crew performance. (3) Operation of carry-on equipment that cannot be secured with existing cargo restraints while in use, thereby increasing the danger to the operator and crew in the event of an accident.
(4) Operation of carry-on equipment energized to emit any form of radiation, gases, liquids, or debris that may be hazardous, such as explosive ordnance, explosive or flammable fluids, laser energy, and so forth. (5) Operation of carry-on equipment, if intended use is, in lieu of a standard aircraft system, subsystem, or component function. c. Commercial off the shelf equipment adopted for Army aviation use will be assessed for airworthiness impact. The assessment will include— (1) Review of any existing airworthiness approval for potential adoption if applicable to the Army system.
(2) Determination of the airworthiness qualification impact of the COTS equipment and its installation on the authorized configuration. Chapter 3 Airworthiness Documents Section I Types of Airworthiness Documents 3–1. Airworthiness release An airworthiness release is a technical document that provides operating instructions and limitations necessary for safe flight of an aircraft system, subsystem, or allied equipment. This Army airworthiness approval is— a. Based on the results of design analysis, engineering ground test, and/or flight test and b.
Required prior to operation of a new aircraft system, subsystem, or allied equipment or a modification (see para 2-7) to the qualified or standard configuration. 3–2. Interim statement of airworthiness qualification An interim statement of airworthiness qualification is a document establishing a preliminary or provisional qualification status and an airworthiness release that is issued when an aircraft and/or its subsystems must be used before completing the full qualification process. This statement and airworthiness release is based on preliminary results of contractor and Government engineering tests.
It lists all known or suspected conditions and limitations; provides precautions necessary for use of the aircraft system, subsystems, and allied equipment; and is updated as additional test data become available. The operator’s technical manual is based on these limitations when applicable. 3–3. Statement of airworthiness qualification A statement of airworthiness qualification is a final document establishing full qualification status and airworthiness release that is issued in conjunction with the Airworthiness Qualification Substantiation Report.
This statement and airworthiness release is based on final results of engineering tests conducted on the aircraft and its subsystem or allied equipment. Issuance of this statement coincides with type classification Standard A, if applicable, and normally completes the airworthiness qualification program. Since all of the prescribed limits are provided to operational units in the technical manuals, the statement of airworthiness qualification is normally not sent to the field nor required to be kept with individual aircraft records. 3–4.
Airworthiness approval An airworthiness approval is any technical document that provides operating instructions and limitations necessary for safe flight of an aircraft system, subsystem, or allied equipment. This document is issued by the airworthiness authority agency (such as the Federal Aviation Administration, National Aeronautics and Space Administration, U.S. Air Force, U.S. Navy, or a foreign authority whose airworthiness approval has been accepted by a U.S. agency) exercising engineering cognizance over the aircraft system for which the airworthiness approval is granted. This approval is— 5 AR 70–62 • 7 July 2000
