Narrative

BUSTED ASSIGNED ALT BY 300-500' ON CLBOUT TO FL230 DURING RAPID CHANGES IN HDG VECTORS (PRESUMABLY FOR TFC) AND ALT RESTRICTIONS (ALSO TFC CALLED AND OBSERVED ABOVE AND SEVERAL MI AWAY); I.E.; CLRED TO FL230 THEN RESTR TO FL200 OR FL210 (UNCERTAIN). ADJACENT CENTER (CHICAGO) APPARENTLY REFUSING ENTRY INTO HIGH ALT SECTOR (ADVISED FL230 TO BE FINAL) WHEN FL310 FILED AND 'CLRED AS FILED;' (LUK-TVC). MUCH CONFUSION IN COCKPIT AND AT CENTER WHEN ALL OF US WAKE UP TO BEING ABOVE FL200 AND CENTER SAYS; 'GET BACK DOWN TO FL200!!!' CENTER THEN ASKED WHAT IS ALT; TO WHICH WE REPLY; 'DSNDING THROUGH 20300' TO FL200.' SHORT PAUSE AND THEN; 'TURN LEFT 50 DEGS FOR TFC;' AND THEN 'CLB TO FL230.' SEVERAL MINS LATER WHILE CREW IS STILL TRYING TO REMEMBER WHAT THE SEQUENCE OF EVENTS WERE; DIFFERENT CTLR VOICE SAYS CALL CENTER ON PHONE (#) UPON RETURN TO BASE; 'THERE MAY HAVE BEEN A VIOLATION OF REQUIRED SEP.' CALLED CENTER ON RETURN TO BASE AND ADVISED THAT PROB OCCURRED BUT DIDN'T HAVE THE 'PACKAGE FROM THE FLOOR YET;' (BAD DAY) BUT 'OUR FSDO WOULD BE INFORMED.' WAITING FOR NEXT FAA MOVE NOW AFTER TALKING TO FSDO WHO HAD NO KNOWLEDGE AS YET. PROBS ON CREW'S PART: POOR CREW COORD ON REVISING ALT (CAPT ACCEPTS RESPONSIBILITY) ALERTER SETTING WITH CHANGES IN ALTS CLBING TO! NO FLT DIRECTOR COMMAND BAR WARNING OF ALT BUST. POSSIBLE PROBS WITH ADI/FD THAT HAD JUST BEEN WORKED ON. PLT HAND FLYING USING FLT DIRECTOR. LATER FOUND AUTOPLT/FD WORKED OK; BUT ADI NOT SLAVING PROPERLY TO NEW VG JUST INSTALLED AND GND CHKED OK; ADI REPLACED AND ALL SYS NOW OK. CENTER PROBS: TOO MUCH CONFUSION AUDIBLE IN BACKGROUND. FIGHTING OVER HDOFS WITH ADJACENT CENTER. CHICAGO CENTER OF CLEVELAND REFUSING TO ALLOW N/S TFC TO CLB INTO ALTS ABOVE FL230 WHILE XING E/W FLOW INTO CHICAGO. TOO MANY CLOSE ALT RESTRICTIONS!!!
