Weights and Measures: Every luggage scale tested at airport failed

Posted: Updated:

TUCSON - The state's temporarily shut down the scales used by United and Delta airlines to weigh passenger luggage at Tucson International Airport.

The state Department of Weights and Measures took the action yesterday after testing the scales and finding violations with all of them.

The scales will remain out of service pending repair and recertification.

United and Delta were the first airlines chosen as part of regular but rare state testing last done in 2004.

A Weights and Measures spokesman called the results disturbing because every scale tested failed.

A spokesman for Delta said the weight discrepancy was minor and likely did not affect many passengers, but added the company will fix the problems.

United says it certified its Tucson scales in June and will investigate to see what went wrong.
