ASTM F2426-05a(2008)

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Standard Guide on
Wing Interface Documentation for Powered Parachute
Aircraft
This standard is issued under the fixed designation F 2426; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This guide covers the manufacture of powered parachute aircraft and their qualification for certification.
1.2 This guide applies to powered parachute aircraft seeking civil aviation authority approval, in the form of flight certificates,
flight permits, or other like documentation.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory
limitations prior to use.
2. Referenced Documents

F2240F 2240 Specification for Manufacturer Quality Assurance Program for Powered Parachute Aircraft
F 2241 Specification for Continued Airworthiness System for Powered Parachute Aircraft
F2242F 2242 Specification for Production Acceptance Testing System for Powered Parachute Aircraft

3. Terminology
3.1 Definitions:
3.1.1 powered parachute, n—aircraft comprised of a flexible or semi-rigid wing connected to a fuselage in such a way that the
wing is not in position for flight until the aircraft is in motion, that aircraft has a fuselage with seats, engine, and wheels (or floats),
such that the wing and engine cannot be flown without the wheels (or floats) and seat(s). Unique to the powered parachute is the
large displacement between the center of lift (high) and the center of gravity (low), which is the pendulum effect. The pendulum
effect limits angle of attack changes, provides stall resistance, and maintains flight stability.
4. Interface Documentation
4.1 Interface documentation is the data necessary for the aircraft manufacturer to complete overall certification to ASTM
powered parachute standards. The following data represents a guide to recommended type, detail, and general format for data
transfer from a major subcontractor to the aircraft manufacturer.
4.2 Manufacturer’s Reference Documents—The following are reference documents that should be supplied to the manufacturer
by the subcontractor. These are intended to be maintained at a current status and referenced by documents provided with each
delivered product.
