American Airlines Mechanic Admits To Tampering With Plane's Navigation System

An American Airlines mechanic is accused of sabotaging a flight over stalled union contract negotiations.

According to a criminal complaint affidavit filed in federal court, Abdul-Majeed Marouf Ahmed Alani admitted during an interview Thursday that he tampered with a navigation system on the plane so that he could collect overtime work.

The plane, with 150 people on board, was scheduled to fly from Miami to Nassau in the Bahamas on July 17. As the pilots powered up the plane at Miami International Airport, they saw an error message for a system that tracks speed, nose direction and other critical flight information and aborted the takeoff.

When mechanics examined the plane, they found a piece of foam glued inside a navigation system part called an air data module. Video from an American Airlines surveillance camera captured a person who drove up to the plane, got out and spent seven minutes working around the compartment containing the navigation system, according to the affidavit.
