responsible for running the quality system about the

person.

3.- Qualification assessment: collecting copies of all

documents that attest to qualification (licence and/or

any authorisation held) followed by a confirmation

check with the organisation(s) that issued such

particular person can electronically issue the

CRS. Magnetic or optical personal card in

conjunction with a personal identity number

(PIN) known only to the individual which is

keyed into the computer.

PART 145.50(c)


1. Does the Maintenance Organisation have a

procedure to ensure that all components whichhave to be installed on the aircraft have been

subject to the alteration required at the date ofinstallation and that all AD`s are complied

with?

Used components prior to PART-145 --> 1 Jan

2000

2. Procedure: issue JAA Form One forcomponents last maintained prior to PART-145.

PART 145.50(d)


1. Procedure when unable(1) to complete all

maintenance required by the customer (being

the aircraft operator) within the aircraftoperators limitations --> entered in the aircraft

CRS before issue of such certificate.

Check for real examples.

(1) Unable means that the maintenance required by the operator could not be completed due either to running out of available maintenance downtime forthe scheduled check or by virtue of the condition of the aircraft requiring additional maintenance downtime.

2. Operator informed in case where full

compliance with 145.50(a) cannot be achieved

within the operators limitations. If the operator

agrees to the deferment of full compliance, then

the CRS may be issued subject to details of thedeferment, including the operator's authority(2),


22/34

Pgina 22 de 34

being endorsed on the certificate.

Check for real examples. (2) Whether or not the operator does have authority to defer maintenance is an issue between the ops and its authority. In case of doubt --> PART145should inform its DGAC, of such doubt, before issue of the CRS. This will allow DGAC to investigate the matter with the ops NAA.

3. Procedure: draw attention to the fact that

145.50(a) does not normally permit the issue of

a CRS in the case of non-compliance.

It should state what action the mechanic,

supervisor and certifying staff should take to

bring the matter to the attention of the relevant

department or person responsible for co-

ordination with the ops (discuss and solve with

the ops).

In addition, the appropriate 145.30(a) person(s)

should be kept informed in writing of suchpossible non-compliance situations.

PART 145.50(e)


1. Aircraft grounded at a location other than themain line station or main base due to non-

availability of a component with the appropriate

release certificate --> temporary fit a componentwithout the appropriate CRS for 30 flight hours

max. or until the aircraft first returns to the main

line station or main base, whichever is sooner,subject to the ops agreement and said

component having a suituable serviceable tag(1)

but otherwise in compliance with all other

PART-OPS 1 or 3 Subpart M and PART-145

req's.(2)

Check real examples.

(1) a tag which clearly states that the aircraft component is serviceable; that clearly specifies the organisation releasing the component together with details

of the JAA-NAA or non-JAA NAA under whose approval the organisation works including the approval or authorisation reference.

(2) making an appropriate entry in the aircraft technical log, checking for compliance with type design standards, modifications, repairs, ADs, life

limitations and condition of the component plus information on where, when and why the aircraft was grounded.

PART 145.50(f)


1. NO CRS when: Non-compliance know to the

PART145 organisation which could hazard

flight safety.

Check Real Examples. Examples: significant cracking, deformation, corrosion or failure of primary structure, any evidence of burning, electricalarcing,, significant hydraulic fluid or fuel leakage and any emergency system or total system failure. An AD overdue.

PART 145.65 (c) 1


1. Maintenance Organisation quality system,

including independent audits. Audits: routine sample checks of all aspects of PART-145 organisation's ability to carry out all maintenance to the required standards and includes someproduct sampling (end result of process). It should include a percentage of random audits carried out on a sample basis when maintenance is being carried

out (during night-> organisations working at night )

2. .Audit Plan : time schedule, content of the

audits to be carried out, random audits on a

sample basis when maintenance is being carried

out (at night, etc.), line stations,

Not each procedure against each product line

when it is common, except if findings have

been identified in that procedure of one productline --> other product lines until the findings

have been rectified.

3. Maintenance procedures subject to annual

inspection in relation to each product model

(Class rating of Appendix 1).

Example: an organisation with a capability to maintain aircraft, engines, brakes and autopilots would need 4 complete audit sample checks each year.

Appendix 5 --> Examples of audit subjects and plans.

4. Product audits (it could be combined with

procedure audits).Combined product audits with procedure audits by selecting a specific product example (aircraft or engine or instrument) and sample checking all the

procedures and requirements associated with the specific product example.

Sample check: to witness any relevant testing and visually inspect the product and associated documentation. Not disassembly unless big findings.
