Quick Answer: What Are Rii’s And Why Are They Critical Aviation Maintenance?

What is critical maintenance task in aviation?

Critical Maintenance Tasks Overhaul, calibration, or rigging of engines, propellers, transmissions, and gearboxes.

What is reliability in aircraft maintenance?

The purpose of a reliability program is to ensure that the aircraft maintenance program tasks are effective and their periodicity is adequate, in addition, the reliability program may result in the escalation or deletion of a maintenance task, as well as the de-escalation or addition of a maintenance task.

What is aircraft maintenance and inspection?

Aircraft maintenance is the performance of tasks required to ensure the continuing airworthiness of an aircraft or aircraft part, including overhaul, inspection, replacement, defect rectification, and the embodiment of modifications, compliance with airworthiness directives and repair.

What is the purpose of AC 120 16F?

Responsible for the development and use of the maintenance Responsible for the selection of an existing inspection program and the Par 2-1 Page 5 Page 10 AC 120 – 16F 11/15/12 program and manual, determining the method of performing maintenance, a required inspection list, a Continuous Analysis and Surveillance System (

What is critical maintenance task?

(n) “ critical maintenance task ” means a maintenance task that involves the assembly or any disturbance of a system or any part on an aircraft, engine or propeller that, if an error occurred during its performance, could directly endanger the flight safety.

What is Cdccl?

Definition: Critical Design Configuration Control Limitations ( CDCCL ): As applied to Fuel Tank safety policy, this term refers to a feature of the fuel system design the integrity of which must be maintained to ensure that unsafe conditions do not develop.

How does MTBF help in aircraft maintenance?

MTBF is used to anticipate how likely an asset is to fail within a certain time period or how often a certain type of failure may occur. When paired with other maintenance strategies, like failure codes and root cause analysis, and additional maintenance metrics, like MTTR, it will help you avoid costly breakdowns.

How is aircraft reliability measured?

Dispatch reliability is expressed as the percentage of flights that depart within a specified time of the scheduled departure time. The airlines define at least three categories:

1. Mechanical (including any maintenance problems)
2. ATC/Weather.
3. Other (including lack of catering or crew, ramp exit blocked, etc)

What is aircraft maintenance program?

ANSWER: The FAA defines a maintenance program as “the performance of tasks required to ensure the continuing airworthiness of an aircraft, including any one or combination of overhaul, inspection, replacement, defect rectification, and the embodiment of an alteration or repair.”

What are the two categories of repairs in an aircraft?

Aircraft Repair

• Making any type of aircraft repair requires an adherence to certain standards and procedures.
• Major repair means a repair:
• Minor repair means a repair other than a major repair.
• Aircraft Structural Repairs.
• Component repairs.
• Systems Repairs.
• Engine Repairs.
• Avionics Repairs.

Why is so important to repair aircraft damage immediately?

The satisfactory performance of an aircraft requires continuous maintenance of aircraft structural integrity. It is important that metal structural repairs be made according to the best available techniques because improper repair techniques can pose an immediate or potential danger.

What is the difference between an annual inspection and a 100 hour inspection?

What is the difference between an annual inspection and a 100 – hour inspection? The inspections themselves are identical. An annual inspection can be performed only by an A&P mechanic who holds an Inspection Authorization, while a 100 – hour inspection can be performed by an A&P mechanic without an IA.

Who is responsible for airworthiness?

That responsibility clearly belongs to the aircraft owner: 14 CFR 91.403(a): The owner or operator of an aircraft is primarily responsible for maintaining that aircraft in an airworthy condition, including compliance with part 39 of this chapter [ Airworthiness Directives].

Why do we need to inspect our aircraft?

The aircraft inspection process is key to the proper performance and airworthiness of any aircraft. Without proper inspections, aircraft are like to run with less effectiveness and to have components and parts that wear down easily and break down in a jam.

Can you overfly an annual inspection?

The annual inspection of the airplane must be completed no later than every 12 calendar months. You can overfly this 100-hour limit by up to 10 hours, but only to reposition the aircraft for its required 100-hour inspection. An annual inspection can be completed instead of a 100-hour inspection.
