Adding an Aircraft Discrepancy
1.
Introduction
The
purpose of tThis
procedure is to provideprovides instructions and guidelines regarding the recording
of aircraft discrepancies within DigiMAINT™.instructions and guidelines
regarding the addition of a new part number to the Generic Parts Index (GPI)
within „DigiMAINT™“.
2.
Execution
Within
DigiMAINT™ a discrepancy can be defined as a deviation from normal or
specified conditions of the aircraft and/or its systems, commonly known as
"snag" or "complaint", requiring a maintenance action. Each
discrepancy is allocated an individual number and given a status indicating its
stage of completion.
DigiMAINT™
distinguishes three types of discrepancies:
1. Discrepancies
which do not affect the airworthiness of the aircraft,
2. Discrepancies
which reduce the airworthiness of the aircraft within MEL limits and
3. Discrepancies
causing the aircraft to be un-airworthairworthinessy, a so calledso-called Aircraft On Ground (AOG)
situation.
Examples of
discrepancies that do not affect the airworthiness of the aircraft may be a
malfunctioning of: external power system, logo lights and passengerand passenger convenience items such as:
galley equipment, reading lamps, etc.
Examples of
discrepancies that reduce the airworthiness of the aircraft may be a
malfunctioning of systems within the limits of the Minimum Equipment List (MEL)
in which the allowable deficiencies are mentioned such as: air conditioning
systems, fire extinguisher systems, horizontal situation indicators, etc.
Examples of
discrepancies that cause an AOG situation may be a malfunctioning of systems
beyond the limits mentioned in the MEL such as: altimeters, AC generators,
engines, etc.
When a
discrepancy is found or reported it shall be recorded in DigiMAINT™. Open
discrepancies will appear on a maintenancemaintenance due list and can be
transferred to a JCN. A history of all
discrepancies will be maintained by DigiMAINT™DigiMAINT™ will maintain a
history of all discrepancies.
The
condition that may lead to add a new part number to the GPI is that the actual
part number needed does not exist in the GPI.
When
it is found necessary to add a new part number to the GPI, one shall make sure
that the new part number is approved by the aircraft manufacturer for
installation on the type of aircraft or equipment it is intended to be used
for. It is for this reason that legitimate reference for each part number is
required. This reference may be: the applicable I.P.C., an Airworthiness
Directive issued by Aviation Authorities, or a Service Bulletin issued by
either the applicable aircraft manufacturer or the part manufacturer.
Within
DigiMAINT™ there are two types of parts: rotable parts and consumable parts.
The main differences between rotable parts and consumable parts are that
rotable parts have a Service Life Limit or are generally repairable (commonly
economical to repair and possible to rehabilitate to a fully serviceable
condition) and consumables are disposable (used only once). Within DigiMAINT™
for rotables the full history w.r.t.
installation, repair, overhaul, etc is maintained. Rotable parts shall always
have a serial number.
NOTE:The same procedure is used to
change the Part Number information, select ‘Change’ instead of ‘Add’ in step 5.
The addition of a new part number to the GPI
consists of four (4) screen
pages. The first page contains
general part information, the second page contains Stores information, the third
contains A/C type and TBO/SLL information, and the fourth page
contains price information.
