General
-
Review and verify previous audits findings
-
What fluid type, make & mix is used on Thomson aircraft (75/25 minimum)? <br>What temperature is the de-icing fluid applied at from the nozzle? <br>How is fluid stored?<br>
-
How many rigs do you have and what are there capacity?
-
Are there any other companies which may be called upon to provide ad-hoc de-ing/anti-icing operations? If so have audit servers been carried out either by visit or questionnaire? (If they are providing services) <br>AEA 6.1.4a3
-
De-icing should be carried out in accordance with approved procedures.<br>6.1.3.3
-
Hand held temp gauges (if applicable) - are they available & calibrated?<br>6.1.3.2
-
Does the contractor possess sufficient de-ice rig safety harness equipment & is it subject to regular recorded safety inspections?<br>6.1.3.2
-
UK only: Harnesses (were used) are inspected periodically and are within 5 year working life from date of first use and 10 year shelf life from date of manufacture. (Raise Obs this is a recommendation if findings).<br>Review records manufacturers life span
-
QUALITY CONTROL
-
Are all manuals current and up to date?<br>Review manuals CAT.op.mpa 250
-
An operator shall establish & maintain a quality assurance programme; identify & action deficiencies.
-
Prior to start of each winter period, a de/anti-icing QA checklist & report to be completed & distributed to relevant personnel.
-
Laboratory checks shall be performed for the fluids at the start and in the middle of the de-icing season, & upon request by the airline. Fluid samples shall be taken from the storage tank & from the de-icing/anti-icing vehicle spray nozzles.
-
Fluid acceptance checks: documentation on arrival; before first use of delivered fluid for tank or vehicle, a sample should be taken & checked for:-<br>Ensure records exist for batches delivered 6.3.2 thru 6.3.6.5
-
Visual (free from contaminants), refractive index, PH value checkfor Type I fluid, plus a field viscosity check for Type II, III & IV fluids.<br>6.3.6.2
-
Field Viscosity checks for type III & type IV fluids are carried out useing falling ball method or Laboratory Viscosity Check<br><br>Verify falling ball method 6.3.6.4
-
Refractometer - verify calibrated & clean, Check the scale across before reading. Ask for distilled water check - index should be 1.333. Instruments to be tested at room temperature of 20 degrees<br><br>Verity 6.3.6.2
-
Storage tanks shall be inspected for corrosion and/or contamination internally on an annual basis. Note If the quality of fluids is checked in accordance with 6.3.4 (start & middle season) the inspection interval may be longer than one year.
-
Stored fluid shall be checked routinely to ensure no degradation or contamination has occurred (storage tank only)
-
The following information shall be recorded & communicated to the flight crew as listed below:-.<br>3.14.2 AEA ISO 11076 12.2
-
Fluid type, mix, local time at beginning of final de-icing, date, and statement "Post de-icing/anti-icing check completed".<br>Verify 3.14.2 ISO 11076 12.2
-
Communication between the Commander and the de-icing crew will usually be achieved using a<br>combination of printed forms and verbal communication. For treatments carried out after aeroplane doors<br>are closed, use of flight interphone (headset) or VHF radio will usually be required.<br>Electronic message boards may also be used in ‘off stand’ situations<br>Observe if poss AEA 3.14 ISO 11076 12.2
-
The flight crew will be notified of the extent of the de/anti-ice operation performed; shall not commence a flight unless the a/c is certificated. <br>Where de-icing takes place after doors are closed, the agent will pass the relevant information by either VHF ground to air, or via the headset (OMA).<br>Observe or question procedure 3.11 (a-d) 8.1 ISO 111076 12.1 oma 8.8.5.8
-
Early de-ice - is the local engineering line station informed when an a/c has the need to be or been early de-iced? Thomson requirement - UK ONLY (if no contact available has the process been documented on the de-icing certificate)<br>Question local procedure GHM section 4 04. B14 1&2 oma 8.8.5.8
-
Application equipment (eg. hoses) shall be cleaned thoroughly before being initially filled with fluid to avoid contamination.<br><br>View cleaning records if available AEA 3.7.5 ISO 11076 7.7.1
-
VEHICLE FLUID & VEHICLE MAINTENANCE
-
Concentration check: fluid or fluid/water mixtures sampes should be taken from the vehicle nozzle & refractive index taken on a daily basis when vehicles are in use. The sample shall be protected against precipitation.<br><br>View rig register 6.3.3.1
-
Fluids shall be heated according to manufacturer's guidelines & not exceeded; the integrity of the fluid following heating shall be checked periodically - the interval should not exceed 2 weeks but maybe adjusted in accordance with local exp.<br>Verify 3.7.4, 6.3 6.3.3.2 ISO 11076 7.6
-
The integrity of the fluid at the spray nozzle shall be checked periodically.<br>Verify 3.7.5 ISO 11076 7.7.3
-
Vehicle maintenance- the company responsible for de-icing shall maintain vehicles/equipment, fluids, training & procedures in accordance with the AEA recommendations or ISO 11076 <br>View vehicle maintenance schedule 6.1.3.2
General observation
-
Dedicated storage tanks to be used and conspicuously labelled & the storage temperature limits shall comply with the manufacturers guidelines. AEA 3.7.1.1 3.7.1.3 & 3.7.1.5 ISO 11076 7.3.1 & 7.3.2
-
De-icing fluid in trucks shall not be heated in confined or poorly ventilated areas. 3.7.5 ISO 11076 7.7.2
-
Post de-icing/anti-icing check an aeroplane shall not be dispatched after a de-icing/anti-icing operation until the aeroplane has received a visual check by a trained and qualified person. 3.11 ISO 11076 10
-
Are any risk assessment carried out as a result of any changes to the business, personnel, trend analysis
-
How are all personnel made aware of any changes to AEA? How are any changes to procedures within the AEA reflected against current working procedures & how are those incorporated into the training plan.<br>Verify any changes to AEA various 2.1.1 AEA training
