This specification covers continued airworthiness requirements for the manufacture of weight-shift-control aircraft and their qualification for possible certification. A safety directive shall be distributed to all registered owners and appropriate CAAwhen a condition is found to exist that may also exist in other aircraft in the fleet and which would cause a deviation from original design or unsafe condition for flight, rendering the aircraft unairworthy. Service bulletins should be distributed to all registered owners by the manufacturer when no unsafe condition exists that could lead to an unairworthy condition, but a service problem has become repetitive for which the manufacturer has developed a design change, or service procedure change that will contribute to the improvement or convenience of operation or maintenance of the aircraft. The manufacturer should issue service letters on any subject that is considered helpful to the owners.

1.1 The following continued airworthiness requirements apply for the manufacture of weight-shift-control aircraft and their qualification for possible certification.

1.2 This specification applies to 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 determine the applicability of regulatory requirements prior to use.
