Boeing has resumed deliveries of aircraft that required replacements of flight deck drip-shields and parts related to environmental control system (ECS) ducts that did not meet US FAA requirements.
The manufacturer says it continues to assess the in-service fleet of affected aircraft to determine the extent and nature of improvements required.
"After extensive testing and analysis with the FAA, Boeing decided to remove and replace flight deck drip shields on about 50 airplanes in production before delivering them," Boeing says in a statement.
"The modification involves the 757, 767, 777 and 747 models.
"Boeing also worked with the FAA on five approved methods to bring the ducts on the 737 Classic, 747, 757-200 and 767 into compliance and conformance with regulatory requirements."
Last week Boeing revealed that insulation used to wrap ECS ducts on some aircraft did not meet US regulatory requirements.
It came soon after the manufacturer said some flight deck drip-shields did not meet requirements.
It has stressed that it does not regard the problems as being of immediate safety concern.
