BOSTON (AP) — A federal report is critical of the MBTA for not having a comprehensive maintenance plan and for its subpar service for the disabled.

The Federal Transit Administration report released Wednesday also says that the T has not hired enough staff to properly monitor a program meant to increase the number of contracts given to minority-owned businesses.

The federal agency reviews the Massachusetts Bay Transportation Authority's compliance with federal regulations every three years. The latest report, dated Nov. 24, stemmed from reviews in September and October.

The report found the T out of compliance in five of 17 areas: maintenance, procurement, access for disabled citizens, helping disadvantaged businesses, and drug-free workplace regulations.

A spokesman tells The Boston Globe (http://bit.ly/1kvLBJY ) the T is following the federal agency's recommendations to develop a detailed maintenance plan.
