Daily Inspection (DI)

General Inspection:

Ventilating Ram air inlet duct for cabin air.
Pitot Heads and static Vents
Drain holes and inspection of derbies on the fuselage
Antennas (underside)
Wheel nose tire
Nose oleo and Piston
Cover Pitot

Before going in depth about the further steps in the inspection, we need to know the areas of the planes that are used as a nomenclature to represent certain parts of the aircraft.
They are:
A1, A2, A3, A4, A5

A1 Internal
Ensure Gust lock- flaps 0 and brakes set

A2 External
Main wheel assembly brake

A2 Internal
Battery and flashlght
firstaid kit- seal check

A3 External
Inspect stabilizers, rudder, elevators, trim and geared tabs

A4 External
Inspect fire extinguishing indicator discs for evidence of extinguisher discharge.
Inspect wing strut
Inspect wing fuel vent outlet
Engine:
Inspect engine intake deflector and screen
Check for oil level
inspect propeller blade

A5 External
Inspect fire extinguishing indicator discs for evidence of extinguisher discharge.
Inspect wing strut
Inspect wing fuel vent outlet
Engine:
Inspect engine intake deflector and screen
Check for oil level
inspect propeller blade

Operational Checks:

Funtional test of position lights, anticollision lights and landing lights.
CVR (Cockpit Voice Recorder)
Beacon test
Portable oxygen test
Emergency exit door and window

ATA numbering system

An aircarft has a lot of parts, manufacturing them is one thing maintaining them is some other level challange. Thus to describe what needs to be done for what part requires a lot of documentation. The easy way engineers have come up is to name each section of the aircraft as different title numbers. ATA- Air Traffic association. It was created by people in ATA so called ATA chapters. with 100 chapters ATA So when some one says ATA chapter 72 it will always mean engine. ATA 27 flight controls ATA 32 landing gear ATA 72 is engine and so on If we go even deeper. ATA 72-00-01 is fan module ATA 72-00-02 is core module ATA 72-00-03 is HPT Module ATA 72-00-04 is LPT module ATA 72-00-05 is AGB module and so on

ACARS (Aircraft Communications Addressing and Reporting System)

ACARS This is a neat way used to bypass the intentional or unintentional human error on reporting flight information during or after flight . Before 1978 AD, this information was given via, voice logs, where captain verbally records the phase of flight and time. This brought human error in the data reporting and was extra work to the pilots. What ACARS does is acts as a reporting machine which reports flight information in different phases of flight to the Ground team. Initially ARINC developed this method for just 4 messages per flight, but now it has turned into a robust means of data link between not just aircraft and ground station but also between aircraft. ACARS (Aircraft Communications Addressing and Reporting System) is a data communications system used for air-ground communication between an aircraft and their own operations centers, air traffic control, and national aviation authorities. ACARS can be used anywhere in the world by connecting to a global ne...

Thrust Reversal

Thrust Reversal consist of 2 words. Thrust and reversal. This is a process adopted to reduce the aircraft velocity during landing. It is a type of braking system. The braking system in an aircraft consist of: 1. Landing Gear brakes. 2. Ground Spoilers 3. Thrust reversal. So while talking about the thrust reversal, the type of aircraft has an important role to play. For the propeller driven aircraft the reverse thrust is achieved with the appropriate change in the blade angle. However for a jet engine the reversal of the thrust come in basically 2 major types: 1. Reversal by the use of hot exhaust. 2. Reversal by the use of cold bypass air. Classification in terms of mechanism used are: 1. Target (bucket) type Operated With hydraulics in turbojet engine 2. Clamshell (Cascade) type Operated with Pneumatics in Low bypass turbofan engine 3. Coldstream type The cold stream reverser system is activated by an air motor in High bypass turbofan engine ...
