General Maintenance Action
Logbook Entry; Aircraft; Human Factors; Procedure
When we arrived at the aircraft; there were three MEL items. Two were in reference to recent maintenance work on the aircraft. One of those required an inflight APU restart; and the second was in reference to work done on both engines that required a flight before the aircraft could be returned to ETOPS status. The specific MEL was 72-XXX; ETOPS In-flight Verification Required. Enroute to the destination; we performed the APU restart; and of course monitored the engines. The Captain was getting a line check; with the Check Airman sitting in the jumpseat. After the successful APU restart; the Check Airman volunteered to do the logbook entries. Although the engine MEL didn't give specific items that we were supposed to check; I did not realize that no logbook entry was made to this MEL. MEL 72-XXX is very generic and; in our case; was unclear [with] what specific checks needed to be accomplished. Also; whether causal or not; there were several distractors on this trip. The Captain was getting a line check; there was an unrelated maintenance problem that caused a two-hour departure delay; and our sequence was being broken up after our arrival at ZZZ.For MEL 72-XXX; in the DP (Departure Procedures) section; the Dispatcher is supposed to 'discuss the ETOPS verification requirements with the Captain.' I'm not aware that this discussion took place; which left us unsure exactly what we were supposed to do to clear this MEL. There should be a line in the 'O' section that says something like; 'The Captain will discuss with the Dispatcher what specific checks need to be accomplished.'
B787 First Officer reported confusion regarding MEL procedures relating to aircraft ETOPS verification and making the required logbook entries.
