AD NUMBER: 2008-22-11
MANUFACTURER: Hawker Beechcraft Corporation
SUBJECT: Airworthiness Directive 2008-22-11 SUMMARY: The FAA is
adopting a new airworthiness directive (AD) for certain Hawker
Beechcraft Corporation (HBC) Model 390 airplanes.
This AD requires you to inspect hydraulic pump pressure output
hose assemblies to determine if they are from the affected lots,
inspect for hydraulic fluid leaks if the hose assemblies are from
the affected lots, and replace all affected hose assemblies.
This AD results from reports of hydraulic leaks from the
hydraulic pump pressure output hose assemblies.
We are issuing this AD to prevent leakage of hydraulic fluid
from the pump output hose within the engine compartment, which
could result in an in-flight fire.
