A 737-300/400/500MAINTENANCE MANUAL
EXCEEDING DESIGN SPEED, STALL, SEVERE TURBULENCE OR BUFFETING CONDITION
_______________________________________________________________________
-MAINTENANCE PRACTICES (CONDITIONAL INSPECTION)
________________________________________________
1. General
_______
A. This procedure contains a task that is an examination of the airplane after one of the following occurs:
(1)
Severe turbulence
(2)
Buffeting
(3)
Airspeed greater than its design speed.
B. This procedure also contains a task that is an examination of the airplane after it stalls (more than the initial buffet or after the stick shaker operates).
C. The data that follows applies to a severe or unusual turbulence
condition.
(1) The pilot must make a decision if a structural inspection is necessary.
NOTE: If an inspection is necessary, refer to the "Examine the
____ Airplane Structure" in this section.
NOTE: Severe turbulence is identified as turbulence which cause
____ large, abrupt changes in altitude and/or attitude. The airplane could be out of control for short periods. It usually causes large variations in airspeed. Passengers and crew are moved violently against their seat belts and loose objects are moved around the airplane.
(2) The flight vertical load acceleration limits that follow are specified in the FAA Flight Manual, Section I. If these flight maneuvering vertical load acceleration limits are exceeded, refer to the Examine Airplane Structure procedure in this section.
(a)
Flaps up . . . . . . . . . . . . . . . . . . . . 2.5g to -1.0g
(b)
Flaps down . . . . . . . . . . . . . . . . . 2.0g to -0.0g
NOTE: With flaps 25 and 30, positive limits vary
____ linearly from +2.0g at maximum landing weight to +1.5g at maximum take off weight.
NOTE: These flight maneuvering vertical load
____ acceleration limits are not directly applicable to severe or unusual turbulence. Severe or unusual turbulence inspections may be required for conditions that do not exceed these limits.
D. This information applies after the airplane is in severe or unusual buffeting:
(1) If an unusual maneuver or a severe or unusual buffet condition occurs in flight, do the Examine Airplane Structure in this section. Also do this examination if an unusual vibration occurs in flight.

E. This information applies when the airplane goes faster than the design speeds:
(1)
The maximum design speed of the airplane for usual flight operations is the Maximum Operating Limit Speed. The Maximum Operating Limit Speed is found in Section 1, LIMITATIONS of the airplane Flight Manual. The aural warning horn will operate at this speed condition.
(2)
If the airplane speed is 20 knots more than the Maximum Operating Limit Speed, do the Examine Airplane Structure procedure in this section.
F. If the airplane continues in a stall farther than the initial buffet or stick shaker condition, a different structural examination is necessary. Do the examination in the Stall (After initial buffet or stick shaker) Examination task in this section.
