Boeing may recommend more frequent checks on 767s

Operators of about 260 Boeing Co. 767 jets may need to inspect engine pylons more frequently. Pylons keep engines attached to aircraft wings.

Boeing could issue revised service procedures in mid-July, following the recent discovery of pylon cracks on two American Airlines 767s, the company said Wednesday.

Boeing and the airline still are trying to determine the cause of the cracks. Boeing could recommend pylon inspections every 400 flight cycles, down from every 1,500.

The recommendation would affect 260 767s out of a worldwide fleet of about 900. A redesign of pylon struts was incorporated beginning with the 664th Boeing 767 made.
