A maintenance worker's failure to remove tape covering the aircraft's static ports caused Aeroperú Flight 603 to crash into the ocean near Lima, Peru, killing all 70 people on board.

A pitot–static system is a system of pressure-sensitive instruments that is most often used in aviation to determine an aircraft's airspeed, Mach number, altitude, and altitude trend. A pitot–static system generally consists of a pitot tube, a static port, and the pitot–static instruments. Other instruments that might be connected are air data computers, flight data recorders, altitude encoders, cabin pressurization controllers, and various airspeed switches. Errors in pitot–static system readings can be extremely dangerous as the information obtained from the pitot static system, such as altitude, is potentially safety-critical. Several commercial airline disasters have been traced to a failure of the pitot–static system.

Aeroperú Flight 603 (PL603/PLI603) was a scheduled passenger flight from Miami International Airport in Miami, Florida, United States, to Arturo Merino Benítez International Airport in Santiago, Chile, with stopovers in Quito, Ecuador, and Lima, Peru. On October 2, 1996, the Boeing 757-23A aircraft flying the final leg of the flight crashed into the Pacific Ocean. There were no survivors among 70 people on board.
