The Detailed Instructions section MUST be used to accomplish all Line Maintenance Checks. Remove the yellow Maintenance in Work placard from F/O s seat back pocket and place in front of throttle levers. Remove placard and re-stow after check is complete. Utilize GSE as much as possible to decrease APU operation. Communicate with flight crew on arrival for any servicing or special requirements. Check aircraft Log Book for pilot reports. Ensure aircraft documents are onboard. To include Aircraft Registration (Must be typed original with signature), Standard Airworthiness Certificate (Must be original on card stock, approximately 5.5 x 4 ), ship s radio license, and Insurance Certificate. Complete B757 Daily EICAS Non-Normal Fault Message Retrieval Form (Form ). Enter all discrepancies and corrective actions in Aircraft Log Book (ATI-021). Record all non-airworthy and non-safety items that are found during the check on the Non-Routine Maintenance Form (ATI-018). If any errors are identified with a Line Maintenance Check, submit a Manual/Job Card/Form Corrections Request and forward to Publications or Quality Control. Any material referenced in the text or tables of the Line Maintenance Checks may be substituted in accordance with the Consumable Material Equivalents List located in Chapter 20, B757 Maintenance Manual. This bullet item does not apply to AD related tasks. This check includes ETOPS tasks which require Techninians to adhere to GMM guidlines when performing maintenance on ETOPS aircraft. CERTIFICATION OF AIRWORTHINESS All signoff pages of the check have been received, action taken where necessary, and initialed properly. Aircraft Logbook properly noted.
