Summary Aviation Maintenance Management 1
,Aircraft Maintenance
Definition of ‘maintenance’
No aircraft is so tolerant of neglect that it is safe in the absence of an effective inspection and
maintenance programme. The processes that affect an aircraft are Deterioration with age (e.g.
fatigue, wear and corrosion) as well as chance failures (e.g. tyre burst, excess structural loads).
“Maintenance is the process of ensuring that a system continually performs its intended
function at its designed-in level of reliability and safety.” [Kinnison and Siddiqui, 2013]
Airworthiness
The term Airworthy “is when an aircraft or one of its component parts meets its type design and
is in a condition for safe operation.”
Certificate of Airworthiness
- The Certificate of Airworthiness (C of A) or Airworthiness Certificate is the formal
document issued by the National Aviation Authority (NAA) to certify that an aircraft is
airworthy.
To remain in airworthy state, all requirements for maintenance, repair and alterations are
performed according to the regulations.
Airworthiness Directive
A notification to owners and operators of a certified aircraft that has a known safety deficiency
with a particular model of aircraft, engine, avionics, or other systems and must be corrected
within a certain time-frame or number of flight-hours/cycles.
They address recommendations for improvements or corrective actions to be implemented by
the holder of the Certificate of Airworthiness
Service Bulletin
A Service Bulletin (SB) is issued by the Original Equipment Manufacturer (OEM) eg. Boeing,
Airbus, Bombardier, Embraer etc. and is issued to:
- Address technical issues
- Product improvements
- Replacements for obsolete (outdated) part numbers
- New procedures, equipment etc.
Categorized in required levels with respect to timing of introduction. Implementation subject
to operator/owner approval and acceptance. SB’s related to AD’s are always mandatory and
categorized priority 1.
Continuing Airworthiness
“All of the processes ensuring that, at any time in its operating life, the aircraft complies with
the airworthiness requirements in force and is in a condition for safe operation.”
The owner/operator of the aircraft is responsible to maintain the a/c, and ensure permanent
airworthiness.
Continuing Airworthiness Management Organization (CAMO)
This is an (approved) organization responsible for implementation of continuing airworthiness
management tasks.
Summary Aviation Maintenance Management 2
, Minimum task list of a CAMO:
1. Tracking of aircraft data.
a. Technical log
2. Management of Maintenance Program (MMP)
3. Control and accomplishment of Airworthiness Directives (AD’s) and
embodiment of policy of non-mandatory modification = Service Bulletins
(SB’s).
4. Analysis of Maintenance Program effectiveness.
5. Major modification standards.
6. Defect reports and fault management.
7. Engineering activities.
8. Reliability program.
9. Pre-flight check/weighing/check flight procedures.
MOE = Maintenance Organization Exposition; document that includes the tasks and
responsibilities of a Maintenance Organization.
EASA Part-145 European Maintenance Facility
An approved maintenance repair facility maintains, repairs, modifies and replaces components
on an aircraft according to approved regulatory specifications as stated under the MOE for
Continued Airworthiness. Part-145 organizations have a “definite” workscope. The workscope
indicates the ‘type’ of work that is allowed to perform.
1. Line (Ramp) Maintenance
2. Base (Hangar) Maintenance
3. Engine Shop
4. Component Shop
Characteristics
- Maintain an aircraft at an approved location.
- Certificate of Release to Service (CRS) line service, and ‘Certificate of Maintenance Review’
(CMR) heavy maintenance is certified by a B1/B2/C certifying engineer only after
completion of all maintenance activities.
- The Certificate of Airworthiness (CoA) renewal is accomplished annually by means of an
audit at the CAMO’s facility. This is collaborated effort between the IL&T regulatory
authority and the CAMO Quality Assurance department.
