21.A.163 Privileges

EASA Form 1 Block 8 ‘Part Number’ The part number as it appears on the item, is usually defined in the design data; however in the case of a kit of parts, media containing software or any other specific condition of supply may be defined in production data developed from design data. Information about the contents of the kit or media may be given in block 12 or in a separate document cross-referenced from block 12. EASA Form 1 Block 12 ‘Remarks’ Examples of conditions which would necessitate statements in Block 12 are: When the certificate is used for prototype purposes the following statement must be entered at the beginning of block 12: ‘NOT ELIGIBLE FOR INSTALLATION ON IN-SERVICE TYPE-CERTIFICATED AIRCRAFT’. Re-certification of items from ‘prototype’ (conformity only to non-approved data) to ‘new’ (conformity to approved data and in a condition for safe operation) once the applicable design data is approved. The following statement must be entered in block 12: RE-CERTIFICATION OF ITEMS FROM ‘PROTOTYPE’ TO ‘NEW’: THIS DOCUMENT CERTIFIES THE APPROVAL OF THE DESIGN DATA [insert TC/STC number, revision level], DATED [insert date if necessary for identification of revision status], TO WHICH THIS ITEM (THESE ITEMS) WAS (WERE) MANUFACTURED. When a new certificate is issued to correct error(s) the following statement must be entered in block 12: ‘THIS CERTIFICATE CORRECTS THE ERROR(S) IN BLOCK(S) [enter block(s) corrected] OF THE CERTIFICATE [enter original tracking number] DATED [enter original issuance date] AND DOES NOT COVER CONFORMITY/ CONDITION/RELEASE TO SERVICE’. Examples of data to be entered in this block as appropriate: For complete engines, a statement of compliance with the applicable emissions requirements current on the date of manufacture of the engine. For ETSO articles, state the applicable ETSO number. Modification standard. Compliance or non-compliance with airworthiness directives or service bulletins. Details of repair work carried out, or reference to a document where this is stated. Shelf-life data, manufacture date, cure date, etc. Information needed to support shipment with shortages or reassembly after delivery. References to aid traceability, such as batch numbers. In the case of an engine, if the competent authority has granted an exemption from the applicable engine environmental protection requirements, the record: ‘Engine exempted from [reference to the type of emission] emissions environmental protection requirement’.

MAINTENANCE The applicant may apply for terms of approval, which cover maintenance of a new aircraft that it has manufactured, as necessary to keep it in an airworthy condition, but not beyond the point at which the applicable operational rules require maintenance to be performed by an approved maintenance organisation. If the production organisation intends to maintain the aircraft beyond that point, it would have to apply for and obtain an appropriate maintenance approval. When the competent authority is satisfied that the procedures required by 21.A.139 are satisfactory to control maintenance activities so as to ensure that the aircraft is airworthy, this capability will be stated in the terms of approval.

MAINTENANCE OF AIRCRAFT Examples of such maintenance activities are: Preservation, periodic inspection visits, etc. Embodiment of a Service Bulletin. Application of airworthiness directives. Repairs. Maintenance tasks resulting from special flights. Maintenance tasks to maintain airworthiness during flight training, demo flights and other non-revenue flights. Any maintenance activities must be recorded in the Aircraft Log Book. It must be signed by certifying staff for attesting the conformity of the work to the applicable airworthiness data. In some cases the Aircraft Log Book is not available, or the production organisation prefers to use a separate form (for instance for a large work package or for delivery of the aircraft to the customer). In these cases, production organisations must use EASA Form 53 which must subsequently become part of the aircraft maintenance records.

MAINTENANCE OF COMPONENTS OUTSIDE THE POA CAPABILITY Such a maintenance activity outside the capability of the aircraft POA holder may still be accomplished under the production approval of the original release organisation. In such circumstances, the engine(s), propeller(s), parts and appliances will require re-release in accordance with point 21.A.163(c) (EASA Form 1). Records relevant to continued airworthiness or retirement lives, such as engine runs, flight hours, landings, etc., which affect part retirement of maintenance schedules must be specified on any re-release. As an alternative the engine, propeller, part or appliance may be maintained by the holder of an approval in accordance with Part 145, classified and released as ‘used’.

1.INTENT This acceptable means of compliance provides means to develop a procedure for the issue of a permit to fly including approval of the flight conditions. Each POA applicant or holder must develop its own internal procedure following this AMC, in order to obtain the privilege of 21.A.163(e) to issue permits to fly for an aircraft under procedures agreed with its competent authority for production, when the production organisation itself is controlling under its POA the configuration of the aircraft and is attesting conformity with the design conditions approved for the flight.

2.PROCEDURE FOR THE ISSUE OF A PERMIT TO FLY

2.1 Content The procedure must address the following points: as relevant, in accordance with 21.A.710(b), the approval of flight conditions; conformity with approved conditions; issue of the permit to fly under the POA privilege; authorised signatories; interface with the local authority for the flight.

2.2 Approval of the flight conditions (when relevant) The procedure must include the process to establish and justify the flight conditions, in accordance with 21.A.708 and how compliance with 21.A.710(c) is established, and include the EASA Form 18B as defined in AMC 21.A.709(b) for the approval under the POA privilege.

2.3 Conformity with approved conditions The procedure must indicate how conformity with approved conditions is made, documented and attested by an authorised person.

2.4 Issue of the permit to fly under the POA privilege The procedure must describe the process to prepare the EASA Form 20b and how compliance with 21.A.711(c) and (e) is established before signature of the permit to fly.

2.5 Authorised signatories The person(s) authorised to sign the permit to fly under the privilege of 21.A.163(e) must be identified (name, signature and scope of authority) in the procedure, or in an appropriate document linked to the Production Organisation Exposition.

2.6 Interface with the local authority for the flight The procedure must include provisions describing the communication with the local authority for compliance with the local requirements which are outside the scope of the conditions of 21.A.708(b) (see 21.A.711(e)).
