(2) Wet sand/dust:
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:
a Clean the top of the aircraft first and then the bottom.
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.

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.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.
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.
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.

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: - Aircraft cleaning is not necessary if you cleaned it before the removal of the protective covers (Ref. AMM TASK 10-11-00-555-014).
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).
- 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.
- Apply the FILM - POLYETHYLENE (square shape (length 600 mm (23.62 in.) and width 600 mm (23.62 in.))) on the protection covers/devices on the probes/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.
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.
B. Internal Inspection
This inspection is not necessary if:
Subtask 05-51-25-210-065-A 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.
