October 2, 1996
Off Pasamayo, Peru
Aeroperu, Flight 603
Boeing B-757-200
N52AW

The aircraft crashed into the ocean 28 minutes after taking off from Lima, Peru. Pieces of adhesive tape were found covering the static ports, placed there by personnel during aircraft maintenance and cleaning, causing the malfunction of the airspeed indicators and altimeters. The crew was not able to correctly determine their altitude and airspeed and with no ground reference over water and at night, crashed into the ocean. An employee did not remove the adhesive tape from the static ports, nor was it detected by any number of people, including the captain, during the preflight inspection.  All 70 aboard were killed.
