ASTM F2427-05a(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.
Designation:F2427–05 Designation: F 2427 – 05a (Reapproved 2008)
Standard Specification for
Required Product Information to be Provided with Lighter-
Than-Air Light Sport Aircraft
This standard is issued under the fixed designation F 2427; 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 specification covers the manufacture of lighter-than-air light sport aircraft.
1.1.1 This specification covers the minimum requirements for information that shall be provided by the manufacturer or seller
of new lighter-than-air aircraft as a part of the initial sale or transfer to the first end user.
1.2 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. Terminology
2.1 Definitions:
2.1.1 airship—engine-driven lighter-than-air aircraft that can be steered.
2.1.2 AOI—Aircraft Operating Instructions.
2.1.3 balloon—lighter-than-air aircraft that is not engine-driven, and that sustains flight through the use of either gas buoyancy
or an airborne heater.
2.1.4 lighter-than-air aircraft—aircraft that can rise and remain suspended by using contained gas weighing less than the air
that is displaced by the gas.
2.1.4.1 Discussion—Aircraft may include dynamic lift that derivesderive as much as 20%30 % lift from other than buoyancy.
2.1.5 thermal airship—airship using heated air for a portion of its lift, incorporating design features to prevent nose collapse
due to dynamic pressure and exempt from specific pressurized envelope requirements.
2.1.6 vectored thrust balloon—thermal balloon with thrust capability that does not have design features to prevent forward
envelope collapse due to dynamic pressure and is therefore limited in its lateral speed capability.
3. Information Requirements
3.1 The manufacturer shall provide critical information for each aircraft. This information shall include, but not be limited to,
the information plate attached to the aircraft, the placard notice,Aircraft Operating Instructions, the maintenance manual, and the
manufacturers statement of compliance, as defined in the following paragraphs. Additional aircraft type specific requirements are
provided in the annexes.
3.2 Information Plate—Amanufacturer-issued stainless steel information plate, printed in English, shall be permanently affixed
to the aircraft in a visible location and shall be designed to remain legible for the expected life of the aircraft.The information plate
shall have the required information either stamped or engraved into the plate.
3.2.1 Serial Number—A manufacturer-issued unique identifying number or code.
3.2.2 Name and Manufacturer, shall include the aircraft name, the manufacturer’s name, and the manufacturer’s main location
including, city, state, and country.
3.2.3 Model Number—Amanufacturer-issued unique identifying number or code assigned to each manufactured type of aircraft
having the same structural design or components.
3.2.4 Date of Manufacture—The date (month and year) determined by the manufacturer that the aircraft met his required design
and manufacturing specifications.
4. Placard Notice
4.1 The following placard notice shall be posted in the aircraft passenger area so that it is visible to both the pilot and passenger
This specification is under the jurisdiction ofASTM Committee F37 on Light SportAircraft and is the direct responsibility of Subcommittee F37.60 on Lighter Thanthan
Air.
