ADR.OR.B.040 Changes

CHANGES REQUIRING PRIOR APPROVAL The aerodrome operator should ensure that prior to initiating any change to the aerodrome or its operation, which requires prior approval, an application is submitted to the Competent Authority. The applicant should provide documentation containing a description of the proposed change, in which the following are identified:

(a)the terms of the certificate, and/or the elements of the certification basis, and/or the safety-critical aerodrome equipment and/or aerodrome operator’s management system (as required by ADR.OR.D.005(b)), and the parts of aerodrome manual, which are affected by the change, including relevant appropriate detailed design drawings;

(b)the certification specifications with which the proposed change has been designed to comply with, including the certification specifications for which the applicant proposes to show compliance in a different manner in order to demonstrate an equivalent level of safety (for such cases see AMC1 ADR.OR.B.015(b)(1);(2);(3);(4), paragraph (c)(1));

(c)the requirements of Part-ADR.OR and Part-ADR.OPS, and any other applicable requirements that have to be complied with as a result of the proposed change, including the way in which compliance is intended to be demonstrated; and

(d)the safety assessment required under ADR.OR.B.040(f).

CHANGES REQUIRING PRIOR APPROVAL The following is a list of items which are granted prior approval by the Competent Authority, as specified in the applicable Implementing Rules.

(a)Use of alternative means of compliance as required by ADR.OR.A.015 Means of Compliance.

(b)Changes to the management and notification procedure for changes not requiring a prior approval, as required by ADR.OR.B.015(b)(4) Application for a certificate.

(c)Changes to the certification basis, or the terms of the certificate, as required by ADR.OR.B.040(a)(1) Changes.

(d)Changes to safety-critical aerodrome equipment as required by ADR.OR.B.040(a)(1) Changes.

(e)Changes significantly affecting elements of the aerodrome operator’s management system as required by ADR.OR.B.040(a)(2) Changes.

(f)Changes to the level of protection of rescue and firefighting services as required by ADR.OPS.B.010(a)(1)(2) Rescue and firefighting services.

(g)Implementation of aeroplane operations on specially prepared winter runways as required by ADR.OPS.B.036 Operations on specially prepared winter runways.

(h)Changes to low-visibility procedures as required by ADR.OPS.B.045(b) Low Visibility Operations.

(i)Operation of aircraft that exceed the certified design characteristics of the aerodrome as required by point ADR.OPS.B.090(a).

(j)Changes to the flight procedures. Moreover the Competent Authority may require prior approval for changes to any obstacles, developments and other activities within the areas monitored by the aerodrome operator in accordance with ADR.OPS.B.075, which may endanger safety and adversely affect the operation of an aerodrome, as required by ADR.AR.C.005(e).

ASSESSMENT OF CHANGES

(a)Safety assessment for a change A safety assessment for a change should include:

(1)identification of the scope of the change;

(2)identification of hazards;

(3)determination of the safety criteria applicable to the change;

(4)risk analysis in relation to the harmful effects or improvements in safety related to the change;

(5)risk evaluation and, if required, risk mitigation for the change to meet the applicable safety criteria;

(6)verification that the change conforms to the scope that was subject to safety assessment, and meets the safety criteria, before the change is put into operation; and

(7)the specification of the monitoring requirements necessary to ensure that the aerodrome and its operation will continue to meet the safety criteria after the change has taken place.

(b)Scope of the safety assessment The scope of the safety assessment should include the following elements and their interaction:

(1)the aerodrome, its operation, management, and human elements being changed;

(2)interfaces and interactions between the elements being changed and the remainder of the system;

(3)interfaces and interactions between the elements being changed and the environment in which it is intended to operate; and

(4)the full lifecycle of the change from definition to operations.

(c)Safety criteria The safety criteria used should be defined in accordance with the procedures for the management of change contained in the aerodrome manual. The safety criteria used should, depending on the availability of data, be specified with reference to explicit quantitative acceptable safety risk levels, recognised standards, and/or codes of practice, the safety performance of the existing system, or a similar system.

ASSESSMENT OF CHANGES — LOCAL RUNWAY SAFETY TEAM For the role of the Local Runway Safety Team prior to implementing changes, see also

GM2 ADR.OR.D.027.

ASSESSMENT OF CHANGES – RUNWAY SAFETY Particular attention should be given to changes which may have an effect on runway safety. This includes the introduction of, or changes to noise mitigation or noise abatement procedures.
