6.1.2 Validation
6.1.2.1 All designs, other than a design mentioned in paragraph 6.1.1.1 (g), must be validated in accordance with the Standards mentioned in Chapter 7.
6.1.2.2 On completion of a design, a certified designer must apply to CASA for flight validation.
Note The address for applications is anaa.corro@casa.gov.au or Air Navigation, Airspace and Aerodromes Manager, Civil Aviation Safety Authority, GPO Box 2005, Canberra, ACT 2601.
6.1.2.3 The application is to include a completed draft copy of the design procedure prepared for publication in accordance with a data product specification given to the designer under regulation 175.160 of CASR 1998.
6.1.2.4 CASA shall arrange for a CASA officer who is a qualified validation pilot to conduct the flight validation.
6.1.2.5 The certified designer shall provide an aircraft of a type approved by the CASA officer conducting the flight validation.
6.1.2.6 The certified designer shall provide a qualified designer to be part of the validation crew.
6.1.3 Publication
6.1.3.1 Public Procedures. For a procedure which is to be published in the AIP, the certified designer shall forward to the AIS:
(a) A Certificate of Design signed by the Chief Designer stating that the design has been completed in accordance with CASR Part 173, and,
(b) A copy of the design in the format specified in a data product specification given to the certified designer under regulation 175.160 of CASR 1998.
6.1.3.2 Other procedures. If a procedure is:
(a) not to be published in the AIP; or
(b) not an amended version of a published foreign State procedure where the amendments have been made by an authorised designer;
then, the certified designer, or authorised designer, must provide the following to CASA:
(c) a copy of the design in the format specified in this MOS;
(d) except for an Off-shore Specialised Helicopter Design — a Certificate of Design signed by the Chief Designer stating that the design has been completed in accordance with Part 173 of CASR 1998.
Note The address for applications is anaa.corro@casa.gov.au or Air Navigation, Airspace and Aerodromes Manager, Civil Aviation Safety Authority, GPO Box 2005, Canberra, ACT 2601.
6.1.3.3 Notice of withdrawal. A certified designer or an authorised designer:
(a) who, for paragraph 6.1.3.1 or 6.1.3.2, forwards to the AIS or CASA (as the case requires) a certificate of design, or a copy of a design, for a type of terminal instrument flight procedure (TIFP design); and
(b) who subsequently withdraws the TIFP design in compliance with maintenance requirements under paragraph 6.1.4.1A;
must, as soon as possible after the withdrawal, give written notice to the AIS or CASA (as the case requires) that the TIFP design is withdrawn.
6.1.3.4 NOTAM of withdrawal. As soon as possible after receiving a notice mentioned in paragraph 6.1.3.3, the AIS or CASA (as the case requires) must ensure that a notice of the withdrawal of the TIFP design is published in the AIP or a NOTAM.
6.1.4 Maintenance
6.1.4.1 Maintenance of a Terminal Instrument Flight Procedure includes:
(a) general text and data amendments;
(b) redesign to conform with changes to design standards;
(c) provision of advice regarding obstructions in the vicinity of the aerodrome or procedure;
(d) redesign or amendment required as a result of changes to critical obstacles;
(e) changes as directed by CASA;
but excludes the periodic flight revalidation of procedures.
6.1.4.1A Maintenance of a type of TIFP requires that, if written notification about an aerodrome is received from CASA under paragraph 2.1.9A of the Manual of Standards (MOS) — Part 139 Aerodromes, the following safety procedures must be followed:
(a) withdrawal of the TIFP design for the aerodrome; and
(b) written notification to the aerodrome operator that, in accordance with the maintenance requirements of this paragraph, the TIFP design has been withdrawn because the aerodrome was not a certified aerodrome or a registered aerodrome.
Note This procedure is to complement the obligation on CASA under paragraph 2.1.9A of the Manual of Standards (MOS) — Part 139 Aerodromes that where an aerodrome with a TIFP ceases (for whatever reason) to be certified and does not become registered, or ceases to be registered and does not become certified, CASA will take every reasonable step necessary to give written notification to the certified or authorised designer of the TIFP.
6.1.4.2 At intervals not exceeding five years, CASA shall conduct a flight re-validation of a procedure. On completion of a flight re-validation, CASA will advise the certified designer of any changes required.
6.1.5 Obstacle Clearance Advice to Aerodrome Operators
6.1.5.1 Prior to the effective publication date of a procedure, the certified designer must forward to the aerodrome operator for which a procedure has been designed, diagrams and obstacle data sufficient to enable the aerodrome operator to fulfil obligations to report and monitor obstacles in the vicinity of an aerodrome as required under CASR Part 139.
