While dispatching two aircraft at the same time last night we had an APU door fault on one of the aircraft. While filling out the MEL log item and placard for the APU door message I filled out the log page and started to sign off item and got involved adding a statement to the yellow placard requested by maintenance control. I forgot to come back to that log page and put my signature; I had the date filled out but missed the signature. It was an error on my part trying to get a flight crew out before they timed out. I was trying to comply with too many tasks at one time. Had two departures at the same time and a deadline. Take more time and attention to task at hand.
A Fuel door recycling Airworthiness Directive (AD) was complied with but the misc. 91 was not sent correctly. We were unaware that there was required text that was supposed to be sent along with the misc 91. This was a relatively new AD and the specifics of compliance were confusing. Since neither the First Officer or I had flown since this AD came out; the fact that wording was supposed to accompany the misc 91 was missed. It would be nice if the exact steps required were readily available in the logbook or somewhere handy during the preflight.
Maintenance Technician and a Flight Crew reported the log book was not signed off by maintenance and did not comply with an Airworthiness Directive.
