 A. Hard/Overweight Landing Inspection Requirements (Ref. Fig. 611/TASK 05-51-11-991-015, 612/TASK 05-51-11-991-016)
 (1)
 Definitions There are several categories of hard/overweight landing:

 (a)
 Hard landing A hard landing is a landing with an aircraft weight less than the Maximum landing Weight (MLW) and:

 -
a vertical acceleration (VertG) equal to or more than 2.6 g and less than 2.86 g at aircraft Center of Gravity (CG) or,

 -
a vertical speed (Vs) equal to or more than 10 ft/s and less than 14 ft/s.

 (b)
 Severe hard landing A severe hard landing is a landing with an aircraft weight less than the Maximum landing Weight (MLW) and:

 -
a vertical acceleration (VertG) equal to or more than 2.86 g at aircraft Center of Gravity (CG) or,

 -
a vertical speed (Vs) equal to or more than 14 ft/s.

 (c)
 Overweight landing An overweight landing is a landing with an aircraft weight more than the Maximum landing Weight (MLW) and:

 -
a vertical acceleration (VertG) equal to or more than 1.7 g and less than 2.6 g at aircraft Center of Gravity (CG) or,

 -
a vertical speed (Vs) equal to or more than 6 ft/s and less than 13 ft/s.

 (d)
 Severe overweight landing A severe overweight landing is a landing with an aircraft weight more than the Maximum landing Weight (MLW) and:

 -
a vertical acceleration (VertG) equal to or more than 2.6 g at aircraft Center of Gravity (CG) or,

 -
a vertical speed (Vs) equal to or more than 13 ft/s.

 (e)
 High pitch-rate landing A high pitch-rate landing is a landing during which the pitch rate is more than 10 Deg/sec.

 (2)
 Hard/overweight landing confirmation

 (a)
 It is the responsibility of the flight crew to make a report if they think there was a hard/overweight landing.

 (b)
 After a crew report of a hard/overweight landing, you must confirm the impact parameters to know the category of the landing. To know this, refer to:

 (c) When you know the category of the landing, you must do the inspections for that category.
