AMC1 ML.A.801(e) Aircraft certificate of release to service    

CAA ORS9 Decision No. 1

(a) The aircraft CRS should contain one of the following statements:

(1) ‘certifies that the work specified, except as otherwise specified, was carried out in accordance with Part-ML, and in respect to that work, the aircraft is considered ready for release to service.’; or

(2) for a pilot-owner:

‘certifies that the limited pilot-owner maintenance specified, except as otherwise specified, was carried out in accordance with Part-ML, and in respect to that work, the aircraft is considered ready for release to service.’.

(b) The CRS should relate to the task specified in the DAH’s or operator’s instruction or the AMP which itself may cross-refer to a DAH’s/operator’s instruction in a maintenance manual, service bulletin, etc. This should indicate the revision status of the maintenance instruction used.

(c) The CRS should include the date when the maintenance took place relative to any life or overhaul limitation in terms of date/flying hours/cycles/ landings etc. as appropriate.

(d) When extensive maintenance has been carried out, it is acceptable for the CRS to summarise the maintenance as long as there is a unique cross reference to the work pack containing full details of the maintenance carried out. Dimensional information should be retained in the work pack record.

(e) The person issuing the CRS should use his or her normal signature except in the case where a computer release-to-service system is used. In this latter case, the CAA needs to be satisfied that only this particular person may electronically issue the CRS. One such method of compliance is the use of a magnetic or optical personal card in conjunction with a personal identification number (PIN) known only to the individual, which is keyed into the computer. A certification stamp is optional.

(f) At the completion of all maintenance, owners, certifying staff, operators and maintenance

organisations should ensure they have a clear, concise and legible record of the work performed.

(g) In the case of an ML.A.801(b)(2) CRS, the independent certifying staff should retain all records necessary to prove that all requirements have been met for the issuance of a CRS.
