(Specification)Standard Specification for Production Acceptance Testing System for Lighter-Than-Air Light Sport Aircraft
Standard Specification for Production Acceptance Testing System for Lighter-Than-Air Light Sport Aircraft
ABSTRACT
This specification covers production acceptance test requirements for the manufacture of lighter-than-air light sport aircraft. This provides the minimum requirements for the establishment of a ground and flight test program for verifying the initial (first run) production aircraft meets certain operational performance requirement that have been set forth by the manufacturer in its Aircraft Operating Instructions. The minimum requirements to verify that each subsequent production aircraft has no obvious defects that would prevent the safe operation of the aircraft are described. Every production aircraft shall be flight tested to the minimums such as lighter-than-air airships, hot-air balloons and gas/hybrid balloons.
SCOPE
1.1 This specification covers production acceptance test requirements for the manufacture of lighter-than-air light sport aircraft.
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 determine the applicability of regulatory limitations prior to use.
