Criminal charges against Majeed Marouf Ahmed Alani, filed before a federal court in Miami indicated that the Miami International Airport worker had admitted to federal investigators that on July 17 he had intentionally interfered with the sensors that monitor the speed of the plane and other data crucial.
Fortunately, the crew of American Airlines flight 2834 managed to detect the anomaly before taking off and canceled the trip.
During routine maintenance, a mechanic discovered a poorly connected tube in a compartment under the cockpit, in the nose of the plane, which appeared to have been deliberately obstructed with some type of solid foam.
Alani then admitted to the officers he was upset with the failed contractual negotiations between the maintenance workers and the airline, which had lasted for more than four years.
The mechanic told investigators that it was affecting him financially, according to court documents consulted by the newspaper cited.
Alani has been accused of "voluntarily damaging, destroying or disabling an aircraft" and is expected to have his first court hearing this Friday.
If the pilots had not noticed the fault, they would have had to fly without the assistance of the ship's computers, manually, according to the Miami Herald.
However, Alani assured the authorities that his intention was not to hurt any of the crew or passengers. And that his intention from the beginning was to get the flight to be canceled or delayed so he could get extra hours of work.
"In American We have an unwavering commitment to the safety of our customers and team members and we are taking this matter very seriously, "said a statement from American Airlines spokesman Ross Feinstein.
"At the time of the incident, the aircraft was taken out of service, maintenance was performed and after an inspection to ensure it was safe, the aircraft was back in service. American immediately notified the federal authorities that they took over research with our full cooperation. "
