SAFETY PRECAUTIONS WHILE HANDLING AIRCRAFT SYSTEMS AND ITS COMPONENTS
AIM
To prevent accident and damage to man and material.
OCCASIONS
Whenever required to handle the A/C and its system components and ground equipments.
AIRCRAFT
o Before caring out any work on the A/C, the respective maintenance manual is to be referred for further instructions. The necessary safety precautions are to be strictly followed.
Before entering the cock pit of a fighter A/C, ensure that the ejection seat is in safe and all armament operating switches are in safe position and all the safely pins are in position.
Before switching on the master battery switch ensure that the under carriage selector lever is in down position and latched and all the armament store door switches are in safe condition.
Ensure that the wheel chocks are engaged.
Before operating the control surface, ensure that the control locks are removed.
Before starting the engine.
Chocks are to be kept in front of the wheel.
A/C brake system in serviceable.
A serviceable fire extinguisher is available.
Never tow an aircraft without a person inside the cockpit before towing the A/C, check the brake pressure.
While towing the A/C never exceed the walking speed.
Never drop any tool while working.
While working inside the A/C, collect all the tools and space on completion of the job and ensure no items are left behind.
HYDRAULIC SYSTEM
Always release the system pressure before removing a component from the A/C
Never does any maintenance work on airplane with any other specified oil other than the recommended one.
Carry out the patch test on the system to prevent the contamination of oil. This can be carried out using Millipore patch test kit.
Never mix different grade of hydraulic oil to service the A/C.
Blank all the ports of the removed components and the A/C pipe ends to avoid the entry of dust, dirt and foreign particles.
Follow the necessary precautions to dismantle the hydraulic components.
Avoid spilling of hydraulic fluid on the A/C and in and around from the A/C. If spilled it should be cleaned immediately to avoid slipping.
Before fitting a new hydraulic component, it should be unblanked, degreased, washed and flushed.
While fitting the non return valve and restrictors, ensure that the marked arrows are in the desired direction.
STRUCTURE
Aluminum alloy sub frame with composites nose module, rear fuselage, wing and tail surfaces fabric covered. Tail plane strut placed on x-axis wing traced on x-AIR/humon
LANDING GEAR:
Tricycle type filled two side(vs) hinged to lower longeron plus half axes shock absorbers on all three units, main wheel drum trackers.All tyres 350x80. Optional main wheel speed trailing(standard on human) and nose wheel ground small holes kid at base of fin can be equipped with puddle jumper floats
CONCLUSION
Thus the various safety precautions while handling aircraft system are studied.
