Proposed amendment to Part 173 Manual of Standards Terminal Instrument Flight Procedure (TIFP) flight revalidation interval - (CD 2205AS)

Closed 22 Jul 2022

Opened 8 Jul 2022

Overview

Part 173 of the Civil Aviation Safety Regulations 1998 (CASR) provides the regulations that apply to the design of TIFPs by a certified procedure design organisation (PDO). CASA’s regulatory framework, in particular Part 173 of CASR, is designed to achieve and maintain the strategic objectives of the International Civil Aviation Organization (ICAO) in relation to the safe, regular instrument flight operations at all aerodromes where instrument flight procedures are carried out.

For quality assurance purposes, the Part 173 Manual of Standards (MOS) stipulates the processes to be followed and completed in designing a TIFP, including the revalidation interval of a TIFP. These processes are supported by ICAO Annex 11, ICAO Doc 8618 - PANS-Aircraft Operations Vol. II and ICAO Doc 9906 - Quality Assurance Manual for Flight Procedure Design.  

Part 173 MOS requires that all TIFPs are revalidated by CASA at intervals not exceeding 3 years. ICAO recommends that all TIFPs are revalidated at intervals not exceeding five years:

  • Annex 11 Appendix 7 paragraph 6. state responsibilities concerning the maintenance and periodic review of a TIFP:

A State shall ensure that maintenance and periodic review of instrument flight procedures for aerodromes and airspace under the authority of the State are conducted. Each State shall establish an interval for periodic review of instrument flight procedures not exceeding five years.

Note — Guidance on maintenance and periodic review is contained in the Quality Assurance Manual for Flight Procedure Design (Doc 9906).

  • ICAO Doc 8168 Vol. II PANS-Aircraft Operations (PANS-OPS) Part I — Section 2, Chapter 4, Paragraph 4.4.3 state the maximum interval with regards to the revalidation interval of a TIFP:

Published procedures shall be subjected to a periodic review, including validation, to ensure that they continue to comply with changing criteria, to confirm continued adequate obstacle clearance and that they meet user requirements. The individual States shall establish the interval for periodic review of instrument flight procedures according to the needs of the State. The maximum interval for this review is five years.

Proposed amendment

In line with ICAO Annex 11 and ICAO Doc 8618 – PANS-Aircraft Operations Vol. II, CASA proposes to amend Chapter 6 of the Part 173 MOS for TIFPs to be revalidated at intervals not exceeding 5 years instead of the current 3 year interval requirement.
