within 10 hours time in service after 2 March 2009, unless already accomplished; and, in addition, before further flight anytime the aircraft experiences a hard landing.  Inspect thereafter if cracking is detected, as specified in the Requirement section of this Directive.
             This Airworthiness Directive becomes effective on 2 March 2009.
Background:  The FAA received several reports of fatigue cracking on Models 402A and 402B aircraft, in the area of the auxiliary wing spar where the main landing gear trunnion is mounted.  This condition, unless corrected, could result in failure of the wing auxiliary spar web and cause landing gear collapse during normal landing.  This could lead to loss of control and passenger injury.
