US audit finds gaps in the FAA's oversight of United Airlines maintenance

A federal government audit says FAA staffing shortages and high employee turnover have hindered the agency's oversight of airplane maintenance at United Airlines

The ability of federal safety regulators to oversee airplane maintenance at United Airlines has been hindered by inadequate staffing, high employee turnover and the improper use of virtual inspections instead of on-site reviews in some cases, according to a government watchdog audit released Friday.

The U.S. Transportation Department's inspector general said the Federal Aviation Administration lacks sufficient staffing and workforce planning to effectively monitor United’s large fleet. Past audits by the government watchdog also highlighted FAA challenges overseeing other airline maintenance programs, including at American Airlines, Southwest Airlines and Allegiant Air.

The FAA declined to comment on the findings but referred The Associated Press to a letter it sent the inspector general's office that was included in the audit report. In it, the FAA said it agreed with most of the recommendations and was taking steps to address them by the end of the year.

“FAA will implement a more systemic approach to strengthen inspector capacity and will take other measures to ensure that staffing levels remain sufficient to meet surveillance requirements,” the letter said.

The recommendations included a reevaluation of staffing rules, an independent workplace survey of inspector workloads and office culture, and improved training on accessing and using United's safety data — a current gap that the report said currently keeps inspectors from fully evaluating maintenance issues and safety risk trends.
