(a) The organisation shall report to the competent authority, and to any other organisation required by the State of the operator to be informed, any accident, serious incident and occurrence as defined in Regulation (EU) No 996/2010 of the European Parliament and of the Council1 and Directive 2003/42/EC of the European Parliament and of the Council2. (b) Without prejudice to paragraph (a) the organisation shall report to the competent authority and to the organisation responsible for the design of the aircraft any incident, malfunction, technical defect, exceeding of technical limitations and any occurrence that would highlight inaccurate, incomplete or ambiguous information contained in the operational suitability data established in accordance with Commission Regulation (EU) No 748/2012 [3] or other irregular circumstance that has or may have endangered the safe operation of the aircraft and that has not resulted in an accident or serious incident. (c) Without prejudice to Regulation (EU) No 996/2010, Directive 2003/42/EC, Commission Regulation (EC) No 1321/20074 and Commission Regulation (EC) No 1330/20075, the reports referred in paragraphs (a) and (b) shall be made in a form and manner established by the competent authority and contain all pertinent information about the condition known to the organisation. (d) Reports shall be made as soon as practicable, but in any case within 72 hours of the organisation identifying the condition to which the report relates, unless exceptional circumstances prevent this.

FSTD PERFORMANCE METRICS

(a)

The organisation operating the FSTD should systematically collect data to develop performance

metrics and perform data analysis in order to do all the following:

(1)

demonstrate the performance and use of each FSTD it operates, considering the number

of the FSTDs and how an FSTD performs within the fleet, as applicable;

(2)

assess how well an FSTD supports its intended use;

(3)

identify recurring, systemic technical or operational issues, based on the results from the

performance metrics for the preceding year(s); and

(4)

take timely corrective or preventive actions as necessary.

(b)

At least once per calendar year and in combination with the dossier as referred to in point (d)

of GM3 ORA.FSTD.100, the organisation operating the FSTD should, for each FSTD it operates,

provide the following performance metrics for the preceding year to the competent authority:

(1)

‘Planned available time’ defined as time, in hours, during which an FSTD is available to be

used for training, testing and checking;

(2)

‘Scheduled training time’ defined as time, in hours, during which an FSTD is scheduled to

deliver training, testing and checking;

(3)

‘FSTD support time’ defined as time, in hours, during which an FSTD is intentionally not

available for training, testing and checking;

(4)

‘FSTD downtime’ defined as time, in hours, during which an FSTD is unavailable,

regardless of the cause and contains:

(i)

FSTD failure time, defined as time lost, in hours, during planned available time due

to FSTD-specific failures;

(ii)

external failure time, defined as time lost, in hours, during planned available time

due to external factors;

(5)

‘Lost training time’ defined as the amount of scheduled training time, in hours, not

delivered due to FSTD downtime;

(6)

‘Number of FSTD discrepancies’ determined as deviations from the expected behaviour

or performance of the FSTD;

(7)

‘Number of interruptions during scheduled training time’ which is defined as unplanned

events that temporarily suspend or disrupt an FSTD session, regardless of the completion

of the session;

(8)

‘FSTD availability’ calculated as follows:

(Planned available time - FSTD downtime)/(Planned available time) * 100; and

(9)

‘FSTD reliability’ calculated as follows:

(Planned available time - FSTD failure Time)/(Planned available time) * 100

(c)

The information related to the metrics should be available month by month and overall, for the

preceding 12-month period.

(d)

The organisation operating the FSTD should carry out an analysis of trends, based on the results

from the performance metrics for at least the preceding 12-month period. Such information

should be provided to the competent authority as part of the performance metrics to support

the oversight process.

(e)

The organisation operating the FSTD may develop and provide additional information or metrics

to the competent authority, as appropriate, to demonstrate the performance and utilisation of

the FSTD.

ARINC 433 provides good guidance on FSTD compliance measurement. Metrics should monitor

not only individual FSTD performance but, for larger organisations, how each FSTD is performing

within the fleet. It is also recommended that metrics data be shared, regularly, with the FSTD

manufacturers to allow monitoring for generic problems such as design issues, which may be

best addressed with a fleet-wide solution.

GENERAL

(a)

Preventive action is the action to eliminate the cause of a potential non-compliance or other

undesirable potential situation and prevent recurrence of an existing detected non-compliance

or other undesirable condition or situation.

(b)

Corrective action is the action to eliminate or mitigate the root cause(s) of a detected non-

compliance.

(c)

Correction is the action to eliminate a detected non-compliance.

ROOT CAUSE ANALYSIS

(d)

The organisation operating the FSTD may perform a root cause analysis or use another

appropriate tool to identify the root cause of the non-compliance. Proper determination of the

root cause is crucial for defining effective corrective actions to prevent reoccurrence of the non-

compliance on the FSTD.

(e)

It is important that the analysis does not primarily focus on establishing who or what caused

the non-compliance, but on why it was caused. Establishing the root cause(s) of a non-

compliance often requires an overarching view of the circumstances that led to it, to identify all

possible systematic and contributing factors (human factors, regulatory, organisational,

technical factors, etc.) in addition to the direct factors.

(f)

A narrow focus on single events or failures, or the use of a simple, linear model, such as a fault

tree, to identify the chain of events that led to the non-compliance, may not properly reflect

the complexity of the non-compliance, and therefore, there is a risk that important factors that

must be considered to prevent reoccurrence will be ignored. Such an insufficient or partial root

cause analysis often leads to applying ‘quick fixes’ that only address the symptoms of the non-

compliance. A peer review of the results of the root cause analysis may increase its reliability

and objectivity.

(g)

The analysis should consider whether the non-compliance equally affects other FSTDs operated

by the organisation.

ED Decision 2026/006/RPDF page 16

FSTD PERFORMANCE METRICS

(a)

Organisations should develop and maintain a consistent methodology to calculate and report

performance metrics. These values are not only a means to demonstrate compliance with point

ORA.FSTD.100(d) but also form part of the organisation’s management system for ensuring

continued FSTD performance. This data can also inform proactive maintenance decisions and

support dialogue with FSTD users, FSTD providers and competent authorities.

(b)

The performance metrics may be used by the organisation operating the FSTD to demonstrate

to the competent authority:

(1)

the performance of an FSTD to facilitate the competent authority’s assessment on

extension of the recurrent evaluation period of the FSTD;

(2)

the effectiveness of its management system with regard to the FSTD operation and

maintenance.

(c)

For calculation of the metrics as referred to in point (b) of AMC1 ORA.FSTD.100(d), the following

may serve as guidance:

(1)

‘FSTD support time’ may include the following times:

(i)

out of service: closure of the training centre, scheduled out of service because of

major update;

(ii)

maintenance: preventative and corrective;

(iii)

engineering: development, improvement of the FSTD;

(iv)

regulatory: authority evaluation, QTG rerun, activities under point ORA.FSTD.225,

fly-out;

(v)

configuration: change of configuration, time between two FSTD sessions, etc.

(2)

‘FSTD downtime’ can be during scheduled training or even when the training is not

impacted. This metric takes into account all events that could affect the availability of the

FSTD.

(3)

‘External failure time’ is time lost during planned available time due to external factors

such as facility related causes; operator/user causes; scheduling/logistical causes;

environmental or external disruptions.
