Require all operators of Airbus single-aisle and Bombardier CL-600 airplane models to revise existing aircraft maintenance manual procedures and maintenance inspection documents to require a dual inspection signoff to confirm that engine fan cowls are latched after completing anyengine maintenance that involves the opening of an engine fan cowl. (A-08-79)

Require all operators of Airbus single-aisle and Bombardier CL-600 airplane models to require maintenance personnel to inform flight crews when engine fan cowls have been openedbefore flight. (A-08-80)

Require all operators of Airbus single-aisle and Bombardier CL-600 airplane models to provide guidance to maintenance personnel and flight crews on how to inspect engine fan cowls to verify that they are latched properly. (A-08-81)

Determine the extent of the problem of engine fan cowl separations on all airplanes and, should a widespread problem exist for any airplanes, require operators of those airplanes to include a dual inspection signoff in their maintenance procedures to confirm that engine fan cowls are latched after completing any engine maintenance that involves the opening of an engine fan cowl.
