Ground operations employees load luggage on a Southwest Airlines Co. Boeing Co. 737 aircraft on the asphalt at John Wayne Airport (SNA) in Santa Ana, California, USA, Thursday, April 14, 2016.
The US Federal Aviation Administration examines Southwest Airlines for widespread lack of accurate tracking of the overall weight of controlled bags loaded on its jets, according to a Wall Street Journal report on Monday.
The US Civil Aviation Agency's annual civilian probe was found systemic and significant errors with employee calculations and baggage uploads, resulting in potential discrepancies when pilots calculate starting weights, Journal says, citing governments and internal city documents.
The FAA has not decided to impose fines or other penalties, the report reported people who were familiar with the survey as said.
The inaccuracies ranged from a few dozen pounds to more than 1,000 p ounds beyond what the paperwork indicated, kicking disputes between the company and some agency inspectors about potential security implications, the report said.
A spokesman for the company said it is an open Letter of Investigation (LOI) which is a common mechanism for the FAA to document and share security interests or concerns with an airline.
The airline has not been issued fines and is facing no enforcement regarding the weight and balance program, said Southwest spokesman Brandy King.
"In this case, LOI addresses a problem that Southwest voluntarily reported to the FAA last year, and since that time, Southwest has implemented controls to tackle weight and balance program problems, and shared those measures with the FAA," King said. ] FAA could not be reached immediately for comment.
