eyelet fitting of the cockpit windshield center-post to the forward fuselage. We are issuing this 

AD to detect failed bolts and correct the attaching parts of the lower eyelet fitting of the cockpit 

windshield center-post, which could lead to loss of structural integrity of the airplane. Since this 

condition may occur in other airplanes of the same type and affects flight safety, an immediate 

corrective action is required. Thus, sufficient reason exists to request compliance with this AD 

in the indicated time limit without prior notice. 

REQUIRED ACTION:

Inspection and replacement of the attaching parts of the lower eyelet fitting of the 

cockpit windshields center post. 

COMPLIANCE:

You are responsible for having the actions required by this AD performed within 

the compliance times specified, unless the actions have already been done.
