Narrative:

Second leg in a newly purchased (used) and overhauled aircraft. First time aircraft used 'on line' with this airline. Numerous problems and log entries with maintenance trying to get aircraft on line for busy passenger loads. 4 MEL's carried. 1 (leading edge slat indicator) requiring operations limit of 300 KTS, .65 mach. Nearly empty aircraft, climbing through 2000 ft MSL at departure airport. 'Pack trip' annunciator. Duct pressure at normal psi. Mechanical anomaly. One of these indicators was wrong. Followed checklist. First item: 'select warmer temperature.' no control over mixing valve -- won't respond in 'manual' or 'automatic.' second item: 'push reset.' did this and 'pack trip' light extinguished. No change in psi -- still normal!? Back to mix valve problem. Changed from PNF to PF. Had first officer locate 'mix valve' breaker. Hard to find. Not discretely marked. Circuit breaker 'in.' we pulled and reset it anyway. Mix valve now functional. By this time we were level at FL260 at .65 mach. Exchanged controls back to first officer. Center inquired about airspeed. We had neglected to advise controller of mach .65 change as opposed to our 'canned' standard flight plan of .72 mach. Contributing factors: increased workload with 4 MEL's, then additional distrs compounding workload. New captain -- approximately 220 hours PIC in type. Rushed and pressured maintenance to get aircraft on line without adequate system checks for reliability. Solution: fly aircraft first -- including notifying center of airspeed changes. Be late. Take the time to thoroughly go over flight plan and 'file' amended airspeed.

Narrative: SECOND LEG IN A NEWLY PURCHASED (USED) AND OVERHAULED ACFT. FIRST TIME ACFT USED 'ON LINE' WITH THIS AIRLINE. NUMEROUS PROBS AND LOG ENTRIES WITH MAINT TRYING TO GET ACFT ON LINE FOR BUSY PAX LOADS. 4 MEL'S CARRIED. 1 (LEADING EDGE SLAT INDICATOR) REQUIRING OPS LIMIT OF 300 KTS, .65 MACH. NEARLY EMPTY ACFT, CLBING THROUGH 2000 FT MSL AT DEP ARPT. 'PACK TRIP' ANNUNCIATOR. DUCT PRESSURE AT NORMAL PSI. MECHANICAL ANOMALY. ONE OF THESE INDICATORS WAS WRONG. FOLLOWED CHKLIST. FIRST ITEM: 'SELECT WARMER TEMP.' NO CTL OVER MIXING VALVE -- WON'T RESPOND IN 'MANUAL' OR 'AUTO.' SECOND ITEM: 'PUSH RESET.' DID THIS AND 'PACK TRIP' LIGHT EXTINGUISHED. NO CHANGE IN PSI -- STILL NORMAL!? BACK TO MIX VALVE PROB. CHANGED FROM PNF TO PF. HAD FO LOCATE 'MIX VALVE' BREAKER. HARD TO FIND. NOT DISCRETELY MARKED. CIRCUIT BREAKER 'IN.' WE PULLED AND RESET IT ANYWAY. MIX VALVE NOW FUNCTIONAL. BY THIS TIME WE WERE LEVEL AT FL260 AT .65 MACH. EXCHANGED CTLS BACK TO FO. CTR INQUIRED ABOUT AIRSPD. WE HAD NEGLECTED TO ADVISE CTLR OF MACH .65 CHANGE AS OPPOSED TO OUR 'CANNED' STANDARD FLT PLAN OF .72 MACH. CONTRIBUTING FACTORS: INCREASED WORKLOAD WITH 4 MEL'S, THEN ADDITIONAL DISTRS COMPOUNDING WORKLOAD. NEW CAPT -- APPROX 220 HRS PIC IN TYPE. RUSHED AND PRESSURED MAINT TO GET ACFT ON LINE WITHOUT ADEQUATE SYS CHKS FOR RELIABILITY. SOLUTION: FLY ACFT FIRST -- INCLUDING NOTIFYING CTR OF AIRSPD CHANGES. BE LATE. TAKE THE TIME TO THOROUGHLY GO OVER FLT PLAN AND 'FILE' AMENDED AIRSPD.
