 (2)  Examine the areas of the nose landing gear as follows:
 (a)  
Examine the nose wheel well for buckling, and paint that is flaked.

 (b)  
Look for fasteners that have pulled out, or that are not in the web of the nose wheel well.

 NOTE: Look carefully in the area near the trunnion and the
____ support fittings of the drag strut.
 (c)  
Examine the tires of the nose landing gear for damage.

 (d)  
Examine the wheels of the nose landing gear for cracks.

 (e)  
Examine the upper and lower ends of the shock strut for the nose landing gear for signs of hydraulic fluid leakage.

 NOTE: A small quantity of hydraulic fluid on the inner
____
 cylinder is satisfactory.

 (f)

 (3)  Examine the Fuselage and Wing areas as follows:
 (a)  
Examine the engine strut panels, doors, and structure. Look for buckling, cracks, and for fasteners that are pulled out, or are not there.

 (b)  
Examine the leading edge wing-to-body fairing for movement from its usual position. Look for fastener hole elongation or tear out, and cracks in the skin. Also look for fasteners that are pulled out, or are not there.

 (c)  
Look at the inboard trailing edge flaps for damage.

 (d)  
Examine the top and lower fuselage skin panels forward and aft of the wing for buckles, wrinkles or tears.

 NOTE: Permanent wrinkles often occur on the lower side
____ fuselage skins aft of STA 727. An interior inspection is necessary if you find these wrinkles and they did not exist before the landing. If they did exist, examine the wrinkles carefully for cracks.
 (e)  
Examine the keel beam chords, stiffeners, webs, and splices at STA 663 through 727A for distortion, buckled or damaged panels, and pulled or missing fasteners.

 (f)  
Examine the strut-to-wing fairing panels for the top and lower nacelle for buckling, cracks, and pulled or missing fasteners.

 (g)  
Examine the wing leading edge-fairing for displacement, fastener hole elongation or tear-out, skin cracks, and pulled or missing fasteners.
