Looking for someone who might be able to explain this...
1. Maintenance was going at approximately $430K for past several weeks.
2. Last week just ended with maintenance hitting $920K - end of week, as of Mon, Mar 27, 1989 game time.
3. Sort on C Check and last maintenance was completed Mar 8. Next one due Apr 9. So, C Checks are not the cause, as I can tell.
4. All maintenance is set to automatic, so nothing triggered manually by me.
5. No change in aircraft over the period here (i.e. no adds or removes).
What would explain the sudden pop in maintenance?
