Pre-flight Inspection

Pre-Flight Inespection

The visual inspection or walk around is done by the pilot as the final airworthiness check.

In this section we describe were and what to look for when inspecting your aircraft. Any pilot who has build an aircraft will look much deeper and further than normally is required.

There are number of items that need to be checked on the exterior of the aircraft during the walk around:

 ·Cabin

 ·Nose and engine

 ·Right wing trailing edge, wingtip and leading edge

 ·Plane Tail

 ·Left wing leading edge, wingtip and trailing edge

Cabin and Cockpit

In the cabin we need to check for a number of items, most importantly are papers like: the pilot operating handbook or aircraft flight manual, Wight and balance and insurance. Check the movement of the stick/yoke and listen for any odd sounds and check if elevator/ailerons move in the correct direction without problems.

Nose & Engine

Remove the cowlings if you can and check for something loose or event missing, inspect de fan and the oil engine level.

Right wing trailing edge, wingtip and leading edge

The flaps are now in the full down position, this gives us the change to inspect the tracks they move in. Visually look over the wing for dents or wrinkled skins or fuel stains. Proceed towards the wingtip inspecting the aileron.

Tail Plane
Check the trim tab and rudder hinges for any flutter, take a good look at rudder stops and rudder cables. Verify that farings are attached properly with all screws in place.
Verify the marker beacon and the VOR antenna and take a look at the underside.

Left wing leading edge, wingtip and trailing edge
Visually look over the wing for dents or wrinkled skin. Proceed from the root towars the wingtip inspecting  the leading edge.
Make sure the wingtip is firmly attached to the wing.

Air Florida Flight 90 Boeing 737 Ice River Plane Crash

Air Florida Flight 90 On January 13, 1982, the Boeing 737-222 registered as N62AF, crashed into the 14th Street Bridge over the Potomac River just two miles from the White House.

Reasons

The flight crew's failure to use engine anti-ice during ground operation and takeoff, their decision to take off with snow/ice on the airfoil surfaces of the aircraft, and the captain’s failure to reject the takeoff during the early stage when his attention was called to anomalous engine instrument readings. Contributing to the accident were the prolonged ground delay between de-icing and the receipt of ATC takeoff clearance during which the airplane was exposed to continual precipitation, the known inherent pitch up characteristics of the B-737 aircraft when the leading edge is contaminated with even small amounts of snow or ice, and the limited experience of the flight crew in jet transport winter operations.

The hero

Lenny Skutnik saved a priscilla from drowning because she could not hold on to the rescue rope because she was in shock, he jumped into the water and helped her hold onto the rope.

Other accidents for maintenance errors

·1949 Strato-Freight Curtiss C-46A (Maintenance error using sparkplugs not approved for the engine type)

·Aeroperú Flight 603 (Maintenance error; instrument failure due to tape on the static ports)

·Air Midwest Flight 5481 (stall after takeoff due to maintenance error and overloading)

·American Airlines Flight 191 (Loss of control caused by engine detachment due to improper maintenance)

·Atlantic Southeast Airlines Flight 529 (Propeller blade failure due to corrosion, metal fatigue and improper maintenance)

·BEA Flight 706(Explosive decompression, leading to structural failure and loss of contro)

·MacRobertson Miller Airlines Flight 1750 ( metal fatigue caused by maintenace error)

The icredible A380

The incredible A380

The Airbus 380 is 3 times longer than a whale and 10 times more heavier

The Airbus 380 have 555 seats , with 2 class , economy class and first class. But with only 1 class mode the Airbus 380 have 853 Seats , 193 more seats than the biggest B747 configuration.

In 2005, the company needed to sell 260 A380 to make the project profitable, currently they have sold 219 , airbus needs to sell at least 41 A380 more.

also the A380 have 500(8000km) miles of wire ,this is very incredible , because mallorca has a perimeter of 555km ,we could surround mallorca with the A380 cable.

Extra curiosities

The A380 can take off with 590 tons , like 118 elephants, a normal aircraft like 737 can take off with only 85 Tons. Also It has a range of 18,000 kilometers , so we can go around half the planet earth with it.

This plane was the first comercial aircraft to incorporate showers.

All over the world only one person owns an A380 and uses it as a JET-private, the prince Al-waaleed

This amazing aicraft  costs 650 millions dollars and it took 7 years to modify it.

Cold Air Unit

The cold air unit consists of an inward flow turbine driving a centrifugal compressor on a common rotor shaft. The assembly is contained in two main casings, the turbine volute casing and the compressor volute casing. The casings are clamped together by a two-piece clamping ring and enclose a bearing housing. The turbine wheel and the compressor wheel are similar, each consisting of an aluminium alloy wheel cast with aluminium allow blades. The turbine wheel rotates within a nozzle ring and the compressor wheel within a diffuser ring.
