FAA Regulations Require Inspection For Cracks On 767s

The Federal Aviation Administration ordered U.S. airlines to inspect more than 100 Boeing 767 airliners more often than previously required to look for cracks that could cause the engines to fall off, the Associated Press said.

The order comes down in light of the cracks that American Airlines inspectors found in at least two of the 767 planes during routine maintenance. The inspections will affect a whopping 138 of the 314 767 airplanes registered in the U.S.

The FAA issued a safety order back in 2005 requiring inspections every 1,500 flights; the new mandate asks that they get inspected every 400 flights or 90 days.
