Aeroperu 603 : Bricolage Mortel

Aeroperu 603 (Boeing 757 - N52AW) - Tragedy linked to careless maintenance. Here, an employee polishing the aircraft used gray gaffer tape to cover the static ports. The maintenance worker then left without removing the tape. During the pre-flight inspection, conducted at night, the captain failed to notice the tape covering the ports. As a result, upon takeoff (from Jorge Chavez International Airport, Lima), the pilots noticed problems with the airspeed indicator. This reading became increasingly erroneous as the aircraft gained altitude. The altimeters also displayed incorrect values. Other systems on the Boeing 757 require accurate airspeed readings to function. For example, the rudder deflection limiter restricts rudder movement as airspeed increases. Without a speed reading, it began to emit error messages. Subsequently, an error arose related to understanding the origin of the altitude displayed on the air traffic controller's secondary radar. This altitude came from the aircraft's transponder. The transponder takes the altitude from the altimeter chain and transmits it to the air traffic controller. The pilots believed that the altitude communicated to them by the air traffic controller was calculated by the radar and therefore independent of their aircraft. The final point is the failure to respond to the numerous alarms from the GPWS, which detected the approach of water based on the radio altimeter.
