NEW SERVICE DOCUMENT FORMAT To advise and explain the use of a new format.
TCM has adopted a new service document format which will provide the user with an explanation of the compliance criticality of the document. This format was developed by the General Aviation Manufacturers Association (GAMA) to standardize service documents used by aviation manufacturers. The documents will be presented in five categories which are defined below. Each revision to the document will be noted in the information block located at the bottom of each page. This information will include the date of original issuance, revision date, page number and revision number. The most recent revisions to the document will be identified by a solid bold vertical line on the left hand side of the page, adjacent to the revised sentence, paragraph, drawing, etc. SERVICE DOCUMENT CATEGORY DEFINITION CATEGORY 1: "MANDATORY SERVICE BULLETIN" (MSB) – Service documents, relating to known or suspected hazards to safety, that have been incorporated in whole or in part in an Airworthiness Directive (AD) issued by the FAA or have been issued, at the direction of FAA, by the manufacturer, in order to allow compliance with an already issued AD (or an equivalent issued by another country's airworthiness authority). CATEGORY 2: "CRITICAL SERVICE BULLETIN" (CSB) - Service documents (not included in Category 1) that have been determined by the product manufacturer to constitute a threat to continued safe operation of an aircraft or to persons or property on the ground unless some specific action (inspection, repair, replacement, etc.) is taken by the product owner or operator. Documents in this category are candidates for incorporation in an Airworthiness Directive issued by the FAA (but may not be). CATEGORY 3: "SERVICE BULLETIN" (SB) - Service documents (not included in Categories 1 and 2) considered by the product manufacturer to constitute a substantial improvement to the inherent safety of an aircraft or component of an aircraft. This "Service Bulletin" category also includes the most recent updates of instructions for continued airworthiness. CATEGORY 4: "SERVICE INFORMATION DIRECTIVE" (SID) – Serviced documents (not included in Categories 1, 2 or 3) that have been determined by the manufacturer to be of value to an owner/operator in the use of a product by enhancing safety, maintenance or economy. CATEGORY 5: "SERVICE INFORMATION LETTER" (SIL) - This category includes all information (not included in Category 1-4) that may be of use to the owner, operator or maintainer of the aircraft.
