I have 3 aircraft with B-checks scheduled on Saturdays. I suddenly noticed that the condition of these 3 aircraft had dropped to 85% levels. Checking further revealed that the Date of next B-check was showing as 24-Dec which was 4 days earlier! Why didnt the B-check happen automatically since it was scheduled?
Specifically for these 3 aircraft, i had earlier done extra maintenance earlier to bring condition back from 90% levels to 100%. Did this somehow deactivate the automatic maintenance?
These 3 aircraft have utilization of 16hours+ every day so see a fair amount of use. I am baffled as to why the B-check for 24-Dec did not kick in as expected.
