FAA 2023-13-08

Supersedes but retains requirements of FAA AD 2021–05–03, which mandated inspections of certain left-hand engine fuel supply hoses and, depending on the inspection results, reinstalling or removing the fuel supply hose from service. It also required installing an improved part and prohibited installing an affected fuel supply hose on any helicopter unless it was installed by following certain procedures. Since the FAA issued this AD, there were reports of difficulties using an adjusting tool to install the improved fuel supply hose. The updated AD expands the applicability, expands the parts installation limitations, and requires using an improved adjusting tool and updated procedures. This AD also updates certain compliance times and clarifies certain requirements.
