NOTE:  If any such conditions are observed, proceed with further examination of nacelle and fairing, as described in 5-51-61, Dragged Engine Nacelle Condition.
L.  Wing, nacelles, fuselage external surfaces, and all landing gear wheel wells, for evidence of fuel or any other fluid leakage.
M.  Whenever the flight load accelerations shown in par. 2.A. are believed to have been exceeded, and the foregoing examinations reveal evidence of extensive damage, the aircraft must be checked for alignment. (Refer to Structural Repair Manual, Chapter 51, Alignment Check Procedure.)
N.  Check landing gear doors for damage and excessive looseness. If gear unsafe warning lights were present at time of turbulence, buffeting or design speed exceedance, check operation of landing gear doors and landing gear uplocks (Ref Chapter 32).
NOTE:  Normal aircraft operation in flight with gear selected 'off' subsequent to turbulence can be taken as proof of satisfactory uplock operation. Similarly, normal gear extension can be taken as proof of satisfactory door operation provided that the door index marks are aligned.
O.  Check all inspection access panels and blowout panels for distortion, displacement, broken latches, skin cracks or delaminations, and pulled or missing fasteners.
P.  Examine wing root and tip fairings for delamination, distortion, flaking paint, cracks, and pulled or missing fasteners.

EXCEEDING FLAP DOWN SPEEDS CONDITION - CONDITIONAL INSPECTION
1. General
A.  The flaps must be examined for damage or unusual conditions if lowered at more than placard speeds.
B.  The conditional inspection should be accomplished as follows:
(1)  
If overspeed was less than 15 knots, do this inspection within 100 flight hours of overspeed indication. 

(2)  
If overspeed was more than 15 knots, do this inspection before next flight.


2.  Flaps Inspection
A.  Flap Area
(1)  Examine for the following:
(a)  
All wing flaps external skin for distortion and pulled or missing fasteners.

(b)  
Flap tracks for cracks or distortion, track attachment points for cracks, distortion, and hole elongation.

(c)  
Flap track support fittings, and wing in-spar surfaces in close proximity to flap support fittings for cracks, distortion, hole elongation, and pulled or missing fasteners.

(d)  
Flap carriages for cracks; bearings and mounting bolts for binding, cracks, distortion, and hole elongation.

HARD LANDING OR HIGH DRAG/SIDE LOAD LANDING CONDITION, OR OFF RUNWAY EXCURSION MAINTENANCE PRACTICES (CONDITIONAL INSPECTION)
1.  General
A.  The Inspection
(1)  
The inspection is divided into two phases (Phase I and Phase II).

(2)  
If the inspection during Phase I does not show that damage has occurred, no moreinspections are necessary.

(3)  
If the Phase I inspection shows that damage has occurred, the Phase II Inspection is necessary. 

(4)  
If you find damage in the Phase II inspection, inform Boeing about the total damage found. Additional inspections may be required.


B.  Hard Landing
(1)  
The hard landing conditional inspection is for hard landings at or below the maximumdesign landing weight limits.

(2)  
The pilot must make a decision if a structural inspection is necessary and enter in aircraftlogbook.


NOTE:  An indication of a hard landing on the main landing gear is a peak recorded vertical acceleration that exceeds 2.1G (incremental 1.1G). This verticalaccelerometer data must be measured by the flight data recorder accelerometerat a data sampling rate of at least eight samples per second. The acceleration threshold for a hard landing inspection may be significantly lower than 2.1 G ifthere is more than two degrees of roll at the time of main gear touchdown, or inthe event the nose gear contacts the runway before the main gear.
(a)  If the landing is also overweight, the Overweight Landing inspection, not the HardLanding Inspection, must be done.
C.  High Drag/Side Load Landing/Off Runway Excursion
(1)  
The Phase I inspection is applicable when a hard landing or high drag/side load landing occurs.

(2)  
A hard landing or high drag/side load landing conditional inspection should be initiated whenever one or more of the following occurs:

(a)  
The airplane skids or overruns from the prepared surface onto an unprepared surface.
