Dear (recipient's name),
I owe my sincerest apologies to you and the entire department for not doing my part to meet our latest deadline. I know that I was entrusted with a large portion of the project and I let everyone down by not completing my part on time. It was never my intention to put you in a bind.
Thank you for covering for me when I had dropped the ball. I promise to work harder in the future.
Sincerely,
(your name)
