Reminder of Annex 6 Part 1:

Operators shall ensure that:

each aeroplane they operate is maintained in an airworthycondition

a flight shall not be commenced until flight preparation formshave been completed certifying that the pilot-in-command issatisfied that:

a) the aeroplane is airworthyThat means that all references for C items are based on this

sentence, so references are airworthiness documents

Inspecting Instructions Check general condition of the airframe:

CorrosionCleanliness (related to the ability to inspect the aircraft)Legibility of markings

Note: markings may be in languages other than English Note: ICAO does not require that break-in points need to be marked (however:

if such markings are being used, they should be according to a certain format) Note: When inspecting markings and placards, inspectors should differentiate

between those required by ICAO and those required by the manufacturerPresence of ice, snow, frostWindshield delamination,Loose or missing fasteners and rivetsPresence and condition of the antennas, of the static dischargersCondition and functionality of the exterior lights etc

Note: Before raising a finding, the inspector should make sure that the affectedlight(s) are required for the type of flight (according to the MEL). Unserviceablelights, not required for the type of flight should be reported as a general remark

A6-I-6.2.4.1 - If areas of the fuselage suitable for break-in by rescue crews inemergency are marked on an aeroplane such areas shall be marked as shownbelow (see figure following). The colour of the markings shall be red oryellow, and if necessary they shall be outlined in white to contrast with thebackground.

A7-3.3.1 - On heavier-than-air aircraft, the marks shall appear once on thelower surface of the wing structure. They shall be located on the left half of

the lower surface of the wing structure unless they extend across the whole ofthe lower surface of the wing structure. So far as is possible, the marks shallbe located equidistant from the leading and trailing edges of the wings. Thetops of the letters and numbers shall be toward the leading edge of the wing

A 310: ICE ACCRETION ON UPPER WING SURFACELIMITED AT OUTER TANKS SURFACEIf noticed during the turn around, and if it is NOT POSSIBLE TODE-ICE the surface before the next take off, the following procedureshould be followed :

Do not exceed a maximum thickness of 3 mm.Apply a penalty of 1 ton to take-off weight.Consider an increase of 1 percent in fuel consumption.


Example


References

A6-I-4.3.5.4 - A flight to be planned or expected to operate in suspectedor known ground icing conditions shall not take off unless the aeroplanehas been inspected for icing and, if necessary, has been given appropriatede-icing/anti-icing treatment.

Accumulation of ice or other naturally occurring contaminants shall be removed so that the aeroplane is kept in an airworthy condition prior to take-off.

Checklist 2 Pages 10-12Inspec tion of the landing gear t ires Laboriousness, person/hour

Operation content and technical requirements (TR) Operations done in case of technicalrequirements discrepancy

Control

Examine landing gear tires and make sure that thereis:- the absence of tires slipping in relation to the drum.Red control stripes on the drum and tire should beconnected (pic. 1);- the correct position of the red mark light point.

Light point mark with diameter (18-20) mm on thetire and chamber valve should be placed on the wheelradius line;

- the absence of mechanic damage: exfoliation,puncture, cut with the length more than 40 mm withthe damage of more than 2 cord layers, and alsoabrasion of coating rubber with the damage of the firstcord layer.Note. For the tire reconstruction selection use thetolerances, stated in Instruction : 5.1-21 from17.03.73.

In the case of tire removal in relationto wheel drum (red control stripes donot coincide) check the air pressurein the tire chamber; it should be:-for the main wheels (7,5 -0,1 +0,2 )kgs/sm 2

(0,736 -0,0098 +0,196 ) MPa;- for the nose gear (-5 5,5) kgs/sm 2

(0,49-0,54 MPa).

Examine the chamber valve, replacethe wheel if necessary.If the light point and the valve areplaced on different radii, take off thewheel give it for the tirereassembling.Change the tire.
