Aircraft Reliability Systems – Understanding the Maths Workshop – 2 Days

Introduction –

Reliability can be about far more than simply maintaining Maintenance Programme (MP) effectiveness and reliability. Data collected through the reliability analysis process can be used to support the optimisation of the maintenance process.

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.

A reliability program may either be a part of the aircraft maintenance program (AMP) or an independent program on its own, with suitable reference in the AMP. Continuing Airworthiness regulations per EASA member states or third country requirements generally define these responsibilities and we know that operators are ultimately responsible and therefore accountable for the airworthiness of their aircraft. EASA & third country regulators always require the inclusion of a reliability programme for an operator of large aircraft and/or when the Maintenance program is based on Maintenance Steering Group (MSG) Logic or on condition monitoring.

This intensive 2 day workshop will explain in detail and raise awareness regarding the management, oversight and methodologies involved in Aircraft Reliability Systems, together with a detailed range of demonstrations and mathematical exercises that are designed to provide the delegate with:

A basic knowledge of statistical analysis, and how these principles are applied to reliability data.

Using worked examples and raw reliability data, understand & apply the mathematical calculations associated with aviation reliability.

Provide guidance and interpretation with regard to data and findings drawn from calculated results.

Guidelines on how to use Standard & Alert Level Deviation principles to set Upper Control Limits.

A demonstration of various forms of data display & reporting that is employed by the typical large aircraft operator with a view to AMP enhancement & optimization.

Detailed Content / Topics – The following Subjects will be addressed –

Day 1 – The Mathematics behind Aircraft Reliability

- Probability Basics
- Descriptive Statistics
- Charts & Graphs
- Tabular Displays
- Probability Laws
- Introduction to Sample Theory
- The basics of distribution
- Discrete (Poisson Distribution Overview)
- Continuous Distribution
- Normal Distribution
- Standard Normal
- Estimation Theory
- Proportions
- Mean Scores

Day 2 – The Mathematics behind Aircraft Reliability

- Calculating Arithmetic Mean
- Calculating Standard Deviation – Population & Sample
- Setting Standard Deviation (68% 95% and 99%)
- Use of Mean & Standard Deviation to set the UCL (Mean + 1SD, Mean + 2SD, etc..)
- Identifying & Managing False Alerts
- Determining Confidence levels, intervals, etc.
- Rate of Failure;
- Mean Time to Failure (MTTF);

- Mean Time Between Unscheduled Removals (MTBUR)
- Mean Time To Removal (MTTR)
- Chance of Failure
- Usefulness

Each of the above topics will be accompanied by worked examples and demonstrations, together with practical exercises that will augment the delegates understanding of the mathematics.

Target Groups –

Quality Assurance staff required to audit the Reliability process, CAMO staff involved in managing the Maintenance or Reliability programs. Other staff with specific general interest.

Pre-requisites –

A background in an aviation airworthiness environment.  

Learning Objectives –

A reliability program provides an appropriate means of monitoring the effectiveness of the maintenance program. This training covers all elements required to ensure you achieve the maximum benefit from your Reliability Program, whilst augment the delegates understanding of the mathematics employed by a wide range of aircraft reliability software systems.

Duration –

2 Days – Each training day will start at 09.00 and finish at 17.00 with appropriate refreshment breaks.

In-house Training –

This training course may be offered to aviation organisations seeking training internally. To this effect, Sofema offers in-house services whereby this course may be adapted to include procedures regarding your internal aviation reliability programme, together with practical sessions utilising reliability data sourced internally from your business.
