The FAA recently issued an Airworthiness Directive which mandates the horizontal stabilizer inspection previously incorporated in the maintenance manual for your Beechjet/Hawker 400 series aircraft.

This added inspection requirement is due to multiple reports of fatigue cracking in the horizontal stabilizer ribs. Most of the aircraft we have inspected do in fact contain this cracking, which has necessitated replacing all the horizontal stabilizer ribs with a newer improved design.

The FAA has deemed this serious enough to issue an AD (2014-15-15):

“We are issuing this AD to detect and correct such cracking, which could result in the failure of the horizontal stabilizer and loss of pitch control of the airplane.”

You can click on this link to read the Airworthiness Directive.

Cutter Aviation is one of only a handful of BeechJet Authorized Service Centers that has the experience, expertise and equipment to complete the inspection and replacement of rib assemblies if necessary.

Please note that per AD (2014-15-15), a complete inspection of the horizontal stabilizer is required before 7400 flight hours or within 6 months after the effective date of this AD, whichever is later.
