No maintenance was performed for a poor condition aircraft

Yesterday the condition of an aircraft went below 50%.As a result the onward flight was cancelled(SIN-HND).Even the fastest connection can not reach the subsequent flight departing from HND that day(HND-JFK-HND).So I manually canceled 3 flights and transferred the aircraft back to HND.Over 24 hours later,nothing happened,the condition still is under 50%.

What’s the solution?or I have to cancel more flights? lost over 1M already.

Maintenance-ratio will be updated when the aircraft departs next time.
