Narrative:

Aircraft owner/ operator reported damage to the propeller. The aircraft was received in for maintenance. The decision was made to replace the propeller. Airworthiness directive (a.D.) 2004-10-14 was inadvertently missed. The error was discovered over the weekend (following the date of propeller installation). The aircraft owner was advised and the aircraft has been grounded. I am familiar with a.D. 2004-10-14. I see it almost daily. Unfortunately; at the time; the [repair] shop was under a heavy workload and I wasn't thinking of everything encompassed within the a.D. I ran the aircraft up. I signed-off the propeller installation. I have reread a.D. 2004-10-14.
