The grounding only affects United's fleet of Boeing 757s and was a voluntary decision by the carrier.

Ian Gregor of the Federal Aviation Administration released a statement saying, "United Airline's decision [Tuesday] was a voluntary measure on United's part.  It is related to ensuring compliance with an Airworthiness Directive (AD)."

"The Airworthiness Directive  requires a modification of the air data computer (ADC) system, which involves installing certain new circuit breakers, relays and related components and making various wiring changes in and between the flight deck and main equipment center," Gregor added.

United's decision could result in several flight cancellations as crews work into Wednesday to perform the maintenance checks, which take about 60 to 90 minutes.
