Refers to any preventative maintenance that either the cabin crew or technicians perform at regular intervals.

Inspecting the engine for wear, tear, gapping, cleaning and examining

Fuel Switches, battery, flight controls, yoke, and avionics are tested during this inspection

Has to perform before the plane flies

Also known as phase inspection

Occurs anytime a component has malfunctioned or is suspected of malfunctioning.

If the tire thread has been worn to the base of any groove anywhere on the tire, it should be replaced

The process of systematically examining, checking and testing aircraft structural members, components and systems, to detect actual or potential unserviceable condition

Includes wheels equipped with solid shock absorbers on light planes, and air/oil oleo struts on larger aircraft

Is a pneumatic air–oil hydraulic shock absorber used on the landing gear of most large aircraft and many smaller ones.

Involves functional checks, servicing, repairing or replacing of necessary devices or components in an aircraft

Also known as (PM), Noticing small problems and fixing it before major one develops

Is any variety of scheduled maintenance to an component or equipment

Are design to help determine the condition of in service equipment in order to estimate when maintenance should be perform.

Performs when one or more indicators shows that component/equipment going to fail or the performance is deteriorating.

Performed to identify isolate and rectify so that fault parts/component can be restored to an operational condition within the tolerances or limits established in operation

Removal, Installation, Repair of landing gear tires

Servicing landing gear wheel bearings, such as cleaning and greasing.

Lubrication not requiring disassembly other tha removal of non structural items such as cover plates, cowlings, and fairings.

Making small simple repairs to fairings, non structural cover plates, cowlings and small patches and reinforcements not changing the contour so as to interfere with proper airflow

Replacing seats or seat parts with replacement parts approved for the aircraft, not involving disassembly af any primary structure or operating system

Replacing bulbs, reflectors, and lenses of position and landing lights

Define the following procedure if it is predictive, planned or preventive maintenance

Servicing landing gear wheel bearings, such as cleaning and greasing.

Lubrication not requiring disassembly other tha removal of non structural items such as cover plates, cowlings, and fairings.

Making small simple repairs to fairings, non structural cover plates, cowlings and small patches and reinforcements not changing the contour so as to interfere with proper airflow

Replacing seats or seat parts with replacement parts approved for the aircraft, not involving disassembly af any primary structure or operating system

Replacing bulbs, reflectors, and lenses of position and landing lights

Eliminates the damage or restoration of damaged airframe, powerplant, propeller or components

That is not done according to accepted practice or cannot be done by elementary operations

Means other than major repair

Repairs made to aircraft that have sustained damage to the structure

Replacements of simple part to an entire overhaul

Consist of replacing part or component.

are normally done in a shop that is qualified to completely disassemble, clean, inspect, repair, reassemble and test the engine

Treated a bit different than than other component because of thier delicate circuit boards and small fragile electrical or electrical parts

Refer to the periodic inspections every commercial and civil aircraft must go through after completing specific number of flying hours or length of time use.

This type of check is performed every 400-600 hours or 200-300 cycles (takeoff and landing = 1 aircraft cycle).

Conducted every 6-8 months, requires approxiamtely 160-180 man hours

Normally accomplished at the maintenance base of the airline where specialized manpower, materials, tooling, and hangar facilities are available

Performed every 20-24 months or a specific number of manufacturer-defined flight hours,

Also known as Intermediate Layover (IL)

Also known “as heavy maintenance visit” conducted every 6-10 years.

General external visual inspection of aircraft structure evidence of damage, deformation, corrosion, missing part

Operationally check emergency lights

Lubricate nose gera retract actuator

Visually check flight compartment escape ropes for condition and security

Visually check the condition of entry door seals

Pressure decay check APU fuel line shroud

The process of systematically examining, checking and testing aircraft structural members components and systems

Provide complete and comprehensive inspection of an aircraft

standardized , basic inspection programs, have no Federal Aviation Administration approval requirements and are identical in scope and detail

A thorough check of an aircraft prior to flying it to ensure that it is airworthy and safe.

review and test for static system and automatic altitude reporting system

Every 24 calendar months or annual inspection. It is needed to test and confirm function of your transponder and look for data errors

must undergo several tests to verify its signal strength. Testing requirements include battery corrosion, the function of contorls, the crash sensor and signal strength.

Is the most economical way of performing inspection and this is the only way of discovering defects

Is one of the oldest of modern nondestructive testing methods and widely used in aircraft maintenance

Penetrants testing are performed on installed parts on aircrafts structure or in power plants

frequently used in fixed installations, consist of a series of modular workstation

designed for processing aircraft small part.

This penetrant testing process penetrant application, washing, and drying are automatic, but developer application, the utraviolet light inspection and interpretation are manually perform

Is a sensitive method of non destructive testing for surface breaking and some subsurface discontinuation in ferro-magnetic materials
