 Electrical Standard Practices Manual (ESPM)

Introduction to ESPM:

The Electrical Standard Practices Manual (ESPM) gives descriptive data and procedures for the electrical installations on all aircraft of the AIRBUS family. The standard practices information in this manual tells you how to do maintenance for the continued airworthiness of the aircraft. The ESPM is part of the Instructions for Continued Airworthiness (ICA). The ESPM always gives the best practices to do the installations or the repairs. There are several chapter 20, depending on the vendor responsible for the system (ECE, Honeywell, etc.) but whatever the vendor, their chapter 20 follows the same layout. The data contained in the ESPM includes: 

- Description of electrical items.
- Removal/Installation of electrical items.
- Electrical checks. - Repair procedures.
- Damage assessment procedures.
- Other procedures as necessary (Cleaning, Inspection/Check, etc.). 

The Electrical Standard Practices data related to Power Plant is shown in the AMM 70-71-XX.

 Difference between Warning, Caution and Note in the ESPM:

- WARNING: Calls attention to use of materials, processes, methods, procedures or limits that you must obey precisely to prevent injury or death to persons.

 - CAUTION: Calls attention to methods and procedures that you must obey to prevent damage to equipment.

 - NOTE: Calls attention to methods which make the job easier or give supplementary or explanatory information.

Part Number (P/N) Construction 

You can get access to the ESP information with a P/N. The P/Ns listed in the ESP are made up of two parts: - A basic element which is the standard number/family. - A suffix which defines the item. For example

BASIC ELEMENT (STANDARD) + SUFFIX (ITEM) = FULL P/N

NSA936504 + TC0607  =  NSA936504TC0607

ASNE0261 + CF24        = E0261CF24  

For ASNE standards, the 3 letters "A, S, N" are omitted in the P/N. - For clarity, only the suffix (item) (for example E0617 for ASNE0617) is shown.

ESPM Structure  

The ESPM breakdown is based on a 6-digit numbering system.

- Each chapter (XX) is broken down into sections (XX-Y).
- Each section (XX-Y) is broken down into subsections (XX-YY).
- Each subsection (XX-YY) is broken down into subjects and sub-subjects (XX-YY-ZZ).

Sub Module 7.18: Aircraft Non Destructive Testing (NDT) Techniques

EASA PART 66 / SARI MODULE 7 NON-DESTRUCTIVE TESTING (NDT): Nearly all inspection operations on aircraft structures are carried out visually at intervals specified in the Approved Maintenance Schedule. Sometimes visual examination is not practicable, or there may be some uncertainty about the serviceability of a part and one of the methods of nondestructive examination may be used to determine its condition. Non-destructive tests seek to detect defects such as cracks or corrosion either at the surface of below it and a number of methods are presently in use. In each case the part being tested is not harmed in any way.  The selection of the method to be used will depend on the design of the structure, its accessibility and the nature of the suspected defect. 1. VISUAL INSPECTION Visual inspection is the oldest of the non-destructive methods of testing. It is a quick and economical method of detecting various types of cracks before they progress sufficiently to cause failure. Its reliabi

EWIS BACKGROUND AND TARGET GROUPS

EWIS TRAINING BACKGROUND Over the years there have been a number of in-flight smoke and fire events where contamination sustained and caused the fire to spread. Regulators and Accident Investigators have conducted aircraft inspections and found wiring contaminated with items such as dust, dirt, metal shavings, lavatory waste water, coffee, soft drinks, and napkins. In some cases, dust has been found completely covering wire bundles and the surrounding area. Research has also demonstrated that wiring can be harmed by collateral damage when maintenance is being performed on other aircraft systems. For example, a person performing an inspection of an electrical power centre or avionics compartment may inadvertently cause damage to wiring in an adjacent area. Aviation Accident Investigators have specifically cited the need for improved training of personnel to ensure adequate recognition and repair of potentially unsafe wiring conditions. To fully realise the objectives EWIS, operators, ho

Approved Maintenance Organization | ANO145

 Essays: Question 1: You are the Quality Manager of an ANO-145 organization that carries out Line Maintenance of Boeing B777 Aircrafts. What requirements will you check before issuing the Certification Authorization to the Aircraft Licensed Mechanic in Category B1.1.  Question 2: An ANO-145 organization has a maintenance facility located outside Pakistan. What are the conditions under which the organization can use a certifying staff qualified in accordance with the national aviation regulations of the State in which the organisation facility is registered. Question 3: An aircraft is grounded at a location other than the main base where no appropriate certifying staff is available, how will the aircraft be released for service in this case.  Also write additional requirements for the maintenance organization if any. Question 4:  As per ANO-145 , what are different categories under which the aircrafts components must be segregated? Also explain how the unsalvageable items can be permitt
