Inspection after a Flight through a Sand/Dust Storm or after Sand/Dust Contamination on the Ground


TASK 05-51-25-200-002-A
Inspection after a Flight through a Sand/Dust Storm or after Sand/Dust Contamination on the Ground


1. Reason for the Job
This procedure gives information about the inspection of the aircraft:
  • After a flight in sand/dust storm condition, or
  • After sand/dust storm contamination when the aircraft was on the ground.
NOTE: Definition of a sand/dust storm:
A sand/dust storm is an unusual condition in which strong winds blow large quantities of sand/dust into the air. A sand/dust storm goes on large areas and decreases visibility very much.
It is the responsibility of the operator to make the decision to do the inspection after a sand/dust storm conditions.
NOTE: The necessary inspections are related to the preservation level of the aircraft before the sand or dust storm events.
The inspections are necessary for the components/systems for which there was no preservation or unsatisfactory preservation (sand or dust found behind the protection covers/devices).
The inspection of the probes/sensors is always necessary.
NOTE: An adjustable access platform (2.5m to 17m (8.2ft to 55.9ft)) is necessary to get access to the different parts of the aircraft during the inspection.

Subtask 05-51-25-941-051-A
A. General
   (1) Inspection requirements
     (a) The sand/dust particles can be of different dimensions, they can go into all orifices and cause erosion, etching or shot peening on the surface.
The sand/dust can stay:
  • On all exposed lubricated surfaces
  • In all corners
  • In bottom areas.
The sand/dust can cause contamination on all filter elements.
     (b) All the necessary inspections are visual unless the text gives other instructions. Operators can refer to the Non-destructive Testing Manual (NTM) and use non-destructive procedures.
     (c) If you find damage to the aircraft structure, refer to the Structural Repair Manual (SRM). The SRM has the approved damage limits and repair procedures.
     (d) If you find damage to paint/protection, refer to the Structural Repair Manual (SRM). The SRM has the approved paint/protection repair procedures.
     (e) Examine the aircraft surfaces, structures, systems for contamination, erosion/abrasion, dents, etching, delamination or other damage.

     (a) Before you start, we recommend that you get information from the crew about the flight conditions.
     (b) Make sure that you have the related aircraft Post Flight Report (PFR).
     (c) Do a check of all the events reported by the crew or by the PFR in addition/conjunction with this inspection.
   (2) If contamination occurred when the aircraft was on the ground with preservation from a sand/dust storm (Ref. AMM TASK 10-11-00-553-801):
  • Do not do a check of the systems which have the applicable protective covers/devices if you do not find sand/dust behind them.
Subtask 05-51-25-481-051-A
C. Safety Precautions
   (1) Make sure that the safety devices are installed on the landing gears (Ref. AMM TASK 32-00-00-481-001).

   (1) Make sure that the hydraulic systems are depressurized
(Ref. AMM TASK 29-00-00-864-001)
   (2) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
   (3) Put warning notices in the cockpit to tell persons not to operate the systems.
   (4) Put an adjustable access platform in position near the area you must examine.
4. Procedure
Subtask 05-51-25-160-051-A
CAUTION: DO NOT RUB THE SURFACE WHEN YOU REMOVE THE SAND/DUST FROM THE AIRCRAFT. IF YOU RUB THE SURFACE, YOU CAN CAUSE EROSION/ ABRASION.
A. Removal of Sand/Dust Contamination from the External Surfaces
NOTE: If the aircraft was on the ground with preservation from a sand/dust storm:
   (1) Dry sand/dust:
CAUTION: IF THERE IS DRY SAND/DUST, DO NOT USE FLUIDS TO REMOVE THE SAND/DUST. IF THERE IS LAYER OF SAND/DUST ON THE AIRCRAFT SURFACES, REMOVE THE SAND/DUST WITH A VACUUM CLEANER (OR, IF YOU CANNOT USE A VACUUM CLEANER, USE AN AIR BLOWER, A SOFT CLOTH OR A HAND BRUSH). FLUIDS CAN MIX WITH THE SAND/DUST AND MAKE A PASTE THAT CAN CAUSE EROSION/ABRASION. THIS PASTE CAN GO INTO AREAS THAT ARE NOT EASY TO CLEAN.
CAUTION: WHEN YOU BLOW DRY SAND/DUST WITH AN AIR BLOWER, MAKE SURE THAT THE SAND/DUST DOES NOT CAUSE CONTAMINATION OF THE OTHER COMPONENTS (PROBES, ETC.).
     (a) If there is a layer of dry sand/dust on the aircraft surfaces, remove the sand/dust with the VACUUM CLEANER, the BLOWING EQUIPMENT - DRY AIR, Textile-Lint free Cotton - (Material No.14SBA1) or the BRUSH - BRISTLED, SOFT.
   (2) Wet sand/dust:
CAUTION: USE A LOW-PRESSURE WATER SUPPLY EQUIPMENT WITH A MAXIMUM FLOW TO REMOVE WET CONTAMINATION. DO NOT USE A HIGH-PRESSURE SPRAYING EQUIPMENT. DO NOT POINT THE WATER JET IN THE DIRECTION OF THE PROBES AND SENSORS. YOU MUST CLEAN THESE AREAS BY HAND. IF YOU DO NOT OBEY THESE INSTRUCTIONS, DAMAGE TO THE PROBES, WINDSHIELD, DOORS AND OTHER EQUIPMENT CAN OCCUR.
     (a) If there is a layer of wet sand/dust on the aircraft surfaces:
       1 On the static probes, pitot probes, ice detectors (if installed), Angle of Attack (AOA) sensors and Total Air Temperature (TAT) sensors, remove the TAPE - ADHESIVE from the bottom side of the FILM - POLYETHYLENE (if installed before the sand or dust contamination occurred) to let the water drain.
       2 If no FILM - POLYETHYLENE was installed on the probes/sensors before the sand or dust contamination occurred:
         a Remove the contamination from the protection covers/devices (if installed before the sand or dust contamination occurred) and their adjacent structure with Textile-Lint free Cotton - (Material No.14SBA1) .
         b If no protection covers/devices were installed on the probes/sensors before the sand or dust contamination occurred:
  • Remove the contamination from the probes/sensors and their adjacent structure with Textile-Lint free Cotton - (Material No.14SBA1) .
  • Install the protection covers/devices (Ref. AMM TASK 10-11-00-555-013).
         c After the installation of the protection covers/devices on the AOA sensors:
  • Apply the FILM - POLYETHYLENE (diamond shape (length 600 mm (23.62 in.) and width 600 mm (23.62 in.))) on the protection covers/devices on the AOA sensors.
  • Seal the FILM - POLYETHYLENE at the top and on the sides with the TAPE - ADHESIVE. Do not seal the bottom corner of the FILM - POLYETHYLENE on a length of 50 mm (1.97 in.) to let the water drain.
  • Make sure that the FILM - POLYETHYLENE is not too tight on the protection covers/devices on the AOA sensors.
  • Record the locations where you apply the FILM - POLYETHYLENE and the TAPE - ADHESIVE.
         d After the installation of the protection covers/devices on the other probes/sensors (static probes, ice detectors (if installed), pitot probes and TAT sensors):
NOTE: You can apply the FILM - POLYETHYLENE in rectangular shape for the probes/sensors that are near from each other.
  • Seal the FILM - POLYETHYLENE at the top and on the sides with the TAPE - ADHESIVE. Do not seal the bottom side of the FILM - POLYETHYLENE to let the water drain.
  • Make sure that the FILM - POLYETHYLENE is not too tight on the protection covers/devices on the probes/sensors.
  • Record the locations where you apply the FILM - POLYETHYLENE and the TAPE - ADHESIVE.
       3 Remove the sand or dust or from the aircraft surface with a low-pressure water-supply equipment:
         a Clean the top of the aircraft first and then the bottom.
NOTE: Cleaning from the top to the bottom is recommended to make sure that the contamination is fully removed from the aircraft.
         b Carefully clean the recesses and empty spaces (cavities) on the aircraft (e.g. slats, flaps, brakes, landing gears and landing gear bays) where particles can stay.
         c After cleaning, do an inspection of the recesses, empty spaces and outlets on the top of the aircraft (e.g. precooler exhausts). Make sure that there is no contamination on the inner surfaces of these parts.
       4 Refer to the recorded positions and remove all the TAPE - ADHESIVE and the FILM - POLYETHYLENE installed during the preservation procedure.
Subtask 05-51-25-210-064-A
B. Internal Inspection
This inspection is not necessary if:
  • You do not find contamination behind the doors immediately after you open them, and
  • All the doors (passenger and cargo) and windows were closed and the aircraft was in ditching mode during the dust/sand storm.
