Narrative:

Flight was from ZZZ on the morning of may/xx/98. The aircraft had just been released from a heavy C check. It had not flown for more than 2 weeks. It had had the new GPS installed along with power outlets in the back and enhanced GPWS alerts. We had numerous safety of flight issues on this short trip. We encountered a loud wind noise on takeoff from the first officer's clear view window. Then climbing out we had a problem with the pressure controller on the primary side, causing the outflow valve to oscillate. Next we had questions about the display on the captain's HSI when in the navigation mode using GPS. The display did not correspond with what was shown in the flight manual. Then on short final we experienced a stick shaker when approaching the reference speed on final. Associated possibly with this was a cycling of the slat light from land to disagree and back again. We also had a complaint from the flight attendants of a bad air leak from around the aft entry door. All in all a very busy hour. I think in the future we may need to have a fcf (release from maintenance check) flight done on these aircraft which have been torn apart then put back together again and then not flown for several weeks. We were very thankful that all this happened on a week when there was no significant WX to deal with. If a CAT 2 or 3 approach had been required, results might not have been as easy to deal with.

Title: AN MD SUPER 80 WAS RETURNED TO SVC FROM A HVY 'C' CHK WITH NUMEROUS SYS MALFUNCTIONS AND INCOMPLETE MAINT.

Narrative: FLT WAS FROM ZZZ ON THE MORNING OF MAY/XX/98. THE ACFT HAD JUST BEEN RELEASED FROM A HVY C CHK. IT HAD NOT FLOWN FOR MORE THAN 2 WKS. IT HAD HAD THE NEW GPS INSTALLED ALONG WITH PWR OUTLETS IN THE BACK AND ENHANCED GPWS ALERTS. WE HAD NUMEROUS SAFETY OF FLT ISSUES ON THIS SHORT TRIP. WE ENCOUNTERED A LOUD WIND NOISE ON TKOF FROM THE FO'S CLR VIEW WINDOW. THEN CLBING OUT WE HAD A PROB WITH THE PRESSURE CTLR ON THE PRIMARY SIDE, CAUSING THE OUTFLOW VALVE TO OSCILLATE. NEXT WE HAD QUESTIONS ABOUT THE DISPLAY ON THE CAPT'S HSI WHEN IN THE NAV MODE USING GPS. THE DISPLAY DID NOT CORRESPOND WITH WHAT WAS SHOWN IN THE FLT MANUAL. THEN ON SHORT FINAL WE EXPERIENCED A STICK SHAKER WHEN APCHING THE REF SPD ON FINAL. ASSOCIATED POSSIBLY WITH THIS WAS A CYCLING OF THE SLAT LIGHT FROM LAND TO DISAGREE AND BACK AGAIN. WE ALSO HAD A COMPLAINT FROM THE FLT ATTENDANTS OF A BAD AIR LEAK FROM AROUND THE AFT ENTRY DOOR. ALL IN ALL A VERY BUSY HR. I THINK IN THE FUTURE WE MAY NEED TO HAVE A FCF (RELEASE FROM MAINT CHK) FLT DONE ON THESE ACFT WHICH HAVE BEEN TORN APART THEN PUT BACK TOGETHER AGAIN AND THEN NOT FLOWN FOR SEVERAL WKS. WE WERE VERY THANKFUL THAT ALL THIS HAPPENED ON A WK WHEN THERE WAS NO SIGNIFICANT WX TO DEAL WITH. IF A CAT 2 OR 3 APCH HAD BEEN REQUIRED, RESULTS MIGHT NOT HAVE BEEN AS EASY TO DEAL WITH.
