Civil Aviation Regulations 1988

Where a maintenance release in respect of an aircraft ceases to be in force by virtue of an endorsement made under subregulation 47(1), the maintenance release shall again commence to be in force if:

where the endorsement refers to a requirement or condition in respect of the maintenance of the aircraft not having been complied with—there is entered on the maintenance release or other document on which the endorsement was made a certification, in accordance with regulation 42ZE or 42ZN, that the maintenance to which the requirement or condition relates has been completed;

where the endorsement refers to the aircraft having suffered major damage or having developed a major defect—there is entered on the maintenance release or other document on which the endorsement was made a certification, in accordance with regulation 42ZE or 42ZN, that the maintenance required to remedy the damage or the defect, as the case may be, has been completed;

where the endorsement refers to the aircraft having had imposed on it abnormal flight or ground loads—there is entered on the maintenance release or other document on which the endorsement was made a certification, in accordance with regulation 42ZE or 42ZN, that the maintenance required to be carried out to check whether that imposition has caused any damage to the aircraft, and to remedy any damage so caused, has been completed; or

where the endorsement relates to the flight characteristics of the aircraft or the operating characteristics of an aircraft component, or system of aircraft components, installed in the aircraft—there is entered on the maintenance release or other document on which the endorsement was made a certification, in accordance with regulation 42ZE or 42ZN, that the maintenance required to correct the flight characteristics or operating characteristics, as the case may be, has been completed.

Where a maintenance release in respect of an aircraft ceases to be in force by virtue of an endorsement made under regulation 47, the maintenance release shall again commence to be in force if there is entered on the maintenance release or other document on which the endorsement was made a further endorsement signed by an authorised person cancelling the first‑mentioned endorsement.

An authorised person must not make an endorsement under subregulation (2) if there is a reason why the endorsement to be cancelled should remain in force.

A maintenance release that has ceased to be in force by virtue of an endorsement made under regulation 47 shall not again commence to be in force except by virtue of an endorsement made under this regulation.

This regulation does not have effect in relation to a maintenance release issued in respect of an aircraft if:

the period during which the maintenance release is expressed to remain in force has expired; or

a subsequent maintenance release has been issued in respect of the aircraft by virtue of subregulation 43(7).
