The chairman of the House Transportation and Infrastructure Committee said Tuesday that the government is not adequately policing pilot medical certificates.

Chairman James L. Oberstar, D-Minn., said he will hold a hearing later this spring on the Federal Aviation Administration’s decision not to follow up on a 2005 report that said pilots were submitting false medical information.

The Transportation Department’s inspector general found “egregious cases” of pilots who did not disclose serious conditions — such as schizophrenia and bipolar disorder — and thus were certified as medically fit.

The committee’s report suggests that the FAA did not follow up those findings because it thought the number of falsifications among pilots was “negligible.”

Oberstar said the FAA has very strict medical requirements for all pilots but that they must be enforced to be worthwhile.

“These exams are limited and rely heavily on self-reporting,” Oberstar said. “Not all medical conditions are going to be obvious to a doctor who is seeing a patient for the first time. And not all medical problems will show up in a blood test. This is especially true for mental illness.”

FAA spokeswoman Alison Duquette said the agency prioritizes its resources based on the highest risks and that “any falsification of any information in the aviation system is of great concern; however, we have not seen this as a rampant problem.”

Duquette said the FAA will evaluate the committee’s report.
