Narrative:
I was watching news today about how they have not solved one of the crashes, this came to mind. Between jan/92 and may/92 I worked for a service company hired to clean aircraft that remain overnight -- 737/200, md-80 and dc-9's, at the msp airport. On one occasion I was working in the cabin cleaning and I heard a strange noise coming from the cockpit, as I was the only person in the plane I was interested to see what was causing it. I went into the cockpit and to my eerie surprise the pilots steering column was flipping out. It was shaking, vibrating, moving violently from a full forward position to a full back position and making a large amount of noise. It was not caused by wind because there was none. The plane was hooked up to a ground power unit, but as far as I know, no other gauges or instruments were on. I informed air carrier by leaving a note on their operations desk. I do not know if anything was ever done about it or if they even found out what caused it, I think this information might be helpful to repeat.

Title: ACFT CLEANING PERSON OBSERVED THE ACFT CTL COLUMN OF AN MLG MOVE BACK AND FORTH INVOLUNTARILY.
Narrative: I WAS WATCHING NEWS TODAY ABOUT HOW THEY HAVE NOT SOLVED ONE OF THE CRASHES, THIS CAME TO MIND. BTWN JAN/92 AND MAY/92 I WORKED FOR A SVC COMPANY HIRED TO CLEAN ACFT THAT REMAIN OVERNIGHT -- 737/200, MD-80 AND DC-9'S, AT THE MSP ARPT. ON ONE OCCASION I WAS WORKING IN THE CABIN CLEANING AND I HEARD A STRANGE NOISE COMING FROM THE COCKPIT, AS I WAS THE ONLY PERSON IN THE PLANE I WAS INTERESTED TO SEE WHAT WAS CAUSING IT. I WENT INTO THE COCKPIT AND TO MY EERIE SURPRISE THE PLTS STEERING COLUMN WAS FLIPPING OUT. IT WAS SHAKING, VIBRATING, MOVING VIOLENTLY FROM A FULL FORWARD POS TO A FULL BACK POS AND MAKING A LARGE AMOUNT OF NOISE. IT WAS NOT CAUSED BY WIND BECAUSE THERE WAS NONE. THE PLANE WAS HOOKED UP TO A GND PWR UNIT, BUT AS FAR AS I KNOW, NO OTHER GAUGES OR INSTS WERE ON. I INFORMED ACR BY LEAVING A NOTE ON THEIR OPS DESK. I DO NOT KNOW IF ANYTHING WAS EVER DONE ABOUT IT OR IF THEY EVEN FOUND OUT WHAT CAUSED IT, I THINK THIS INFO MIGHT BE HELPFUL TO REPEAT.
