General WARNING When this handbook is used for airplane opera- tional purposes it is the pilot's responsibility to maintain it in current status. AIRPLANE FLIGHT MANUAL SUPPLEMENTS REVISION RECORD Section IX contains the FAA Approved Airplane Flight Man- ual Supplements headed by a Log of Supplements page. On the "Log" page is a listing of the FAA Approved Supplemen- tal Equipment available for installation on the airplane. When new supplements are received or existing supplements are revised, a new "Log" page will replace the previous one, since it contains a listing of all previous approvals, plus the new approval. The supplemental material will be added to the grouping in accordance with the descriptive listing. NOTE Upon receipt of a new or revised supplement, compare the "Log" page just received with the existing "Log" page in the manual. Retain the "Log" page with the latest date on the bottom of the page and discard the other log. VENDOR-ISSUED STC SUPPLEMENTS When a new airplane is delivered from the factory, the handbook delivered with it contains either an STC (Supplemental Type Certificate) Supplement or a Beech Flight Manual Supplement for every installed item requiring a supplement. If a new handbook for operation of the airplane is obtained at a later date, it is the responsibility of the owner/operator to ensure that all required STC Supplements (as well as weight and balance and other pertinent data) are transferred into the new handbook.
