events or incidents related to navigation errors for the operator (eg as reported in a CASA Navigation Error Investigation Form) that have been covered by training, procedures, maintenance or the aircraft navigation system modifications that are to be used;

(f) a revised MEL or flight manual that addresses the standards listed in this MOS and approved by CASA;

(g) a description of the maintenance program that includes a reliability program for monitoring equipment.

      Note   The holder of the design approval, including the type certificate or supplementary type certificate for each individual navigation system installed, must submit a complete set of instructions for continuing airworthiness.

4.2.4 Evaluation, investigation and cancellation

       4.2.4.1Under CASR 91.5155 (3) and 91.5160, if an application is submitted, CASA may begin the following evaluation, investigation and cancellation process:

(a) an examination of each element mentioned in clause 4.2.3; and

(b) a decision on whether or not the material presented can be approved (eg revisions to the MEL, operating history).

       4.2.4.2Under CASR 91.5160 (b), the RNP 4 operational authorisation may be issued subject to conditions or limitations on operations.

       4.2.4.3For CASR 91.5010, navigation accuracy must be determined by:

(a) radar observations of an aircraft's proximity to track and altitude before the aircraft comes into range of short range navaids; and

(b) pilot or operator reports that provide the basis for determining the lateral route spacing and separation minima; and

(c) Automatic Dependant Surveillance — Contract (ADS-C) observations.

       4.2.4.4For CASR 91.5010 (e), the pilot in command must report navigation errors to CASA if there is:

(a) a lateral navigational error of at least 15 NM; or

(b) a longitudinal navigational error of at least 10 NM; or

(c) a longitudinal navigational error of at least 3 minutes variation between the aircraft's estimated time of arrival at a reporting point and its actual time of arrival; or

(d) a navigation system failure.

       4.2.4.5For CASR 91.5010 (e), the Navigation Error Investigation Form is the approved form for reporting navigation errors and equipment failures.

       4.2.4.6For CASR 91.5010 (e), if a navigation error has occurred, CASA and the operator may determine the reasons for the apparent deviation from track or altitude and the steps to be taken to prevent a recurrence.

       4.2.4.7Under CASR 91.5015 (1), and for CASR 91.5010, CASA may cancel an RNP 4 operational authorisation if a repeated navigation error may be attributed to a specific piece of navigation equipment.

       4.2.4.8Under CASR 91.5015 (1), and for CASR 91.5010, CASA may cancel a flight crew member's license if continued errors are being made after remedial action has been completed.
