Narrative:
Usual flight time for a round trip mlb-myat-fpr-mlb is 2.1 hours aircraft flight time. Severe WX caused me to divert twice during this flight. In doing so I overflew a 100 hour airworthiness directive by .6 hours. When I departed on the last leg I had not exceeded the 100 hour limit but severe WX again made the flight longer than expected. I did not know that this airworthiness directive could not be overflown. Our director of maintenance was supposed to do the airworthiness directive every 50 hours so we would never have this overfly problem, but it was not done. To correct this problem I feel it is my responsibility to ground the aircraft if it is anywhere close to the airworthiness directive time limit. I also feel, as an instructor for the company, that I should teach the other capts to do the same.

Title: PLT OF AN SMT TWIN OVERFLEW AN AIRWORTHINESS DIRECTIVE DURING A SCHEDULED TRIP DUE TO WX AVOIDANCE. PLT DID NOT KNOW THAT THERE WAS NO OVER LIMIT TIME DUE TO UNFORESEEN DELAYS BECAUSE OF WX.
Narrative: USUAL FLT TIME FOR A ROUND TRIP MLB-MYAT-FPR-MLB IS 2.1 HRS ACFT FLT TIME. SEVERE WX CAUSED ME TO DIVERT TWICE DURING THIS FLT. IN DOING SO I OVERFLEW A 100 HR AIRWORTHINESS DIRECTIVE BY .6 HRS. WHEN I DEPARTED ON THE LAST LEG I HAD NOT EXCEEDED THE 100 HR LIMIT BUT SEVERE WX AGAIN MADE THE FLT LONGER THAN EXPECTED. I DID NOT KNOW THAT THIS AIRWORTHINESS DIRECTIVE COULD NOT BE OVERFLOWN. OUR DIRECTOR OF MAINT WAS SUPPOSED TO DO THE AIRWORTHINESS DIRECTIVE EVERY 50 HRS SO WE WOULD NEVER HAVE THIS OVERFLY PROB, BUT IT WAS NOT DONE. TO CORRECT THIS PROB I FEEL IT IS MY RESPONSIBILITY TO GND THE ACFT IF IT IS ANYWHERE CLOSE TO THE AIRWORTHINESS DIRECTIVE TIME LIMIT. I ALSO FEEL, AS AN INSTRUCTOR FOR THE COMPANY, THAT I SHOULD TEACH THE OTHER CAPTS TO DO THE SAME.
