INTRODUCTION

• Engineering services formally known as central engineering. Basically works as to provide Engineering support, usually known as Development Engineering for aircraft system and component per ATA chapter wise ,in order to carry out maintenance works. It is also known as Responsible System Engineering (RSE) functions. System Engineers of Central Engineering has the prime responsibilities for accomplishment of Engineering services function

ATA 100 Chapters

Disciplines

There are six departments in Engineering services.

1. Structure Groups.2. Airframe systems Group.3. Propulsion systems Group.4. Electrical/Instrument Group.5. Radio & Radar Group.6. Reliability and Publication Group.

Function of Engineering Services

The main function is to provide necessary document order to do any kind of maintenance job

• Development, review, optimization, amendment, implementation and Control of aircraft maintenance Program for each type of aircraft through Aircraft Maintenance Schedule (AMS) and Component Operating and Storage Limits (COSL).

• Assessment and Technical Evaluation of Technical Literature like Airworthiness Directive (A.D) (mandatory), Service Bulletins, Modification and manufacture’s other Technical problem.

• Incorporation of above mentioned tasks through appropriate Maintenance Directive such as Modification Orders, Repair Orders, Inspection Orders, and Technical Notices etc

Other jobs

• Provide analytical service of different aircraft system performance and product improvement.

• Management and Operation of Reliability Program.• Management and Deferred and Repetitive Defects Analysis .• Provide Engine management service.• Provide landing gear overhaul management.• Provide Repair scheme for aircraft etc.

Objectives

In order to carry out proper maintenance works. The objectives of Engineering services Group is Technical Administration of Aircraft Maintenance Program both schedule and unscheduled and are realized as under:

• To ensure inherent safety and reliability of equipment.• To restore safety and reliability to inherent levels when deterioration has

occurred• To obtain information necessary for design improvement when inherent

reliability is inadequate.• To maintaine the structural requirements.• Cost effective engine management

Activities

• The Structures groupthe Structures group works with the structures maninly . With the supervised by one principal system engineer this department do following works

Analysis of structural defects like damage, corrosion and fatigue monitoring defects and damage and shop reports of related system

components for product improvement. Find out the Damage nature

Damage nature

Conducting various type of reparing works

Damage

Allowable Non allowable

Repair

Onetime Temporary parmenent

The Propulsion systems Group:

On the consideration of safety , Reliability and Economy this department chooses the right step regarding propulsion side. Such as

Engine purchase ( on the basis of safety , reliability and economy) Engine Health monitoring (EHM) Shop visit after a certain period Inflight maintenance support Material management support Reliability support

The Reliability and Publication Group

The Reliability and Publication Group develop is very important department that plays a vital role to make the airplane journey more reliable. Some activities are

Developing review, optimize and control Airframe Maintenance Program for each and every type of aircraft in the fleet;

preparation and control of Maintenance Control Manual (MCM); provide analytical service of different aircraft system performance, product

improvement responsible for amendments, update & revisions of all publications.

Airframe systems Group

Airframe group is concern about the outer shape of the aircraft and if any outer shape is damaged then find out the cause and their solution. They should also aware about the weather condition of their country so that the aircraft can be suitable for them.

Electrical/Instrument Group

Deals with the maintenance and replacement of electrical and electronic components used in the aircraft.

It takes feedback from the maintenance dept. Provides required suggestion.

Radio & Radar Group

Radio and Radar Group follow up the work of maintenance of radio systems and radar of the aircraft. The folloeing part are under this department.

Communication with manufacture company.

• Receive the updates of maintenance procedure from the manufacturer.• Decides whether to implement the updates considering the condition and the

capabilities of the airlines company.• Produce a maintenance procedure following the instruction of the manufacturer.• Suggest the planning engineering dept. to accomplish the job within prescribed

time .• Also monitor updated maintenance work is done on time or not , which is also

monitored by CAAB.• The updated order comes in a form of – 1.Airworthiness Directives (AD) 2. Service Bulletins (SB)

Summary

In Summary Engineering services plays a very vital role in airlines maintenance. Engineering Services provides necessary documentation and analysis with proper working method and also time period to do any kind of maintenance ,repairing or modification works. Without proper documentation no department cant do any sort of job regarding maintenance ,repair and modification. And Engineering Services Supplies that .
