Narrative:

I overflew the duty time limits required under far 135.263D by 30 minutes. The 10 hour crew rest requirements were met both before and after my flight duty period. We received a request for an EMS patient transfer that would normally have been completed in a time frame that would not have violated any crew duty times. Unplanned delay at the patient's originating hospital did not allow me to return in time to avoid working over my crew duty time as outlined under far 135.263.
