AMARILLO, Texas — A federal judge in Texas found a JetBlue Airways pilot who left the cockpit during a flight and screamed about religion and terrorists not guilty by reason of insanity Tuesday.

US District Judge Mary Lou Robinson in Amarillo issued the ruling during a bench trial for Clayton F. Osbon, noting he suffered from a ‘‘severe mental disease or defect.’’

Osbon, who was found mentally competent to stand trial after a court-ordered psychiatric evaluation, will be sent to a federal mental health facility for further examination until another hearing on or before Aug. 6. The judge will decide then whether he can be released or should be committed to a mental facility.

Osbon was indicted on one charge of interfering with a flight crew after the March 27 incident on a flight from Las Vegas to New York.
