During the initial climb, the airspeed and altitude indications were too low. In calm winds, the windshear warning suddenly sounded. The aircraft climbed to FL130, before a return to Lima was initiated. While returning, the captain's airspeed and altitude indications were too high, causing an overspeed warning. At the same time, the co-pilot's airspeed indications were too low, triggering the stick shaker.
The aircraft kept descending and impacted the water with the left wing and no. 1 engine at a 10 degrees angle, at a speed of 260 knots. The aircraft pulled up to about 200 feet and crashed inverted. The captain's airspeed indicated 450 knots and altitude 9500 feet.
The aircraft had flown approx. 2630 cycles.
Preliminary investigation results showed that the aircraft's three static ports on the left side were obstructed by masking tape. The tape had been applied before washing and polishing of the aircraft prior to the accident flight.
