(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:
Hard/Overweight landing criteria Figure 611/TASK 05-51-11-991-015
R 1EFF : 1 1 1CES ALL 1 111 05-51-11 Page 645 Nov 01/01

R - the DMU load report 15 (Ref. TASK 31-37-00-200-001) or,
-the FDRS read out.
(c) When you know the category of the landing, you must do the inspections for that category.
NOTE : If you cannot comfirm the impact parameter values with the
____ DMU or the FDRS, you must do the inspection with the steps for a severe hard/overweight landing.
(3) Inspection preparation
(a) Make sure that you know the category of landing (hard/overweight or severe hard/overweight landing).
NOTE : If you do not know the category of landing, do the
____ inspection with the steps for a severe hard/overweight landing.
(b) We recommend that you get information from the flight crew about the landing conditions, e.g.:
-
touch down straight, drifting, wing low, tail or nose heavy,
-
touch down on main gears or on main and nose gears or high pitch rate on nose gear,
NOTE : After a hard/overweight landing, 3 touchdown
____ configurations are possible:
-
hard touchdown on main gears only: The inspection of the nose gear area is not necessary.
-
hard touchdown on nose gear only (high pitch-rate): Only the inspection of the nose gear area is necessary.
-
hard touchdown on nose and main gears: The full inspection is necessary.
-weight of the aircraft,
-quantity of fuel in each tank,
-instrument indications,
- other information such as noise that could be related to a structural failure.
(c)
We recommend that you get the related Post Flight Report (PFR).
(d)
You must also do all additional checks related to the events specified in the flight crew report or the PFR.
(4) Inspection recommendations
(a)
All the inspections are visual unless otherwise differently in the text. Operators can refer to the Non-destructive Testing Manual (NTM) and use the non-destructive procedures.
(b)
If there is damage to the aircraft structure, refer to the Structural Repair Manual (SRM). The SRM has the approved damage limits and repair procedures.
(c)
If you find damage during an inspection and if it is necessary to disconnect or remove components (pipes, ducts, cables, electrical connectors and mechanical linkages) do a functional test of the related system after re-assembly.
(d)
If it is necessary to open (remove) access panels and doors, examine them. Make sure that:
-
they are aligned correctly,
-
they have no distortion or cracks,
-the paint is not damaged,
-all fasteners and safety devices are in the correct position.

Subtask 05-51-11-860-053
E. Aircraft Maintenance Configuration
(1)
Make sure that the electrical circuits are de-energized (Ref. TASK 24-41-00-862-002).
(2)
Make sure that the hydraulic systems are depressurized (Ref. TASK 29-00-00-864-001).
(3)
Put warning notices in the cockpit to tell persons not to operate the systems.
(4)
Put the adjustable access platform in position.
