A: Since your aircraft was built by AMD, we're assuming that it is the special light-sport aircraft (S-LSA) version. As such, you must comply with the safety alert/safety directive issued by AMD on Nov. 7, 2009. Corrective action steps begin on page 3. In addition to corrective action regarding the upgrade kit, you'll find requirements there for ground and flight testing, modification of the Pilot's Operating Handbook and maintenance manual, and several other tasks — some which need to be done prior to each future flight. Read the document carefully, and become familiar with all of the changes. Once you have done this, we encourage you to talk with the personnel responsible for the upgrade to ensure that the procedures and documentation are in compliance with the safety alert/safety directive.
