145.A.60 requires the organisation to report to the competent authority and the type certificate holder any condition of an aircraft or component identified during maintenance that could seriously hazard the aircraft, and to do so within 72 hours of identification.
What it means in practice
Whenever maintenance personnel identify a condition that has or may have a serious impact on flight safety, the organisation must report it. This includes structural defects, system malfunctions, manufacturing defects, and any other condition that could endanger the aircraft if not corrected. The regulation places a mandatory obligation on the organisation to report, not a discretionary one.
Reports must be submitted to the competent authority, and where the condition relates to a design deficiency, also to the type certificate holder. The reporting must occur within 72 hours of the organisation identifying the condition. Since Regulation (EU) 2021/1963, occurrence reporting is no longer a standalone obligation: it operates as part of the organisation's management system and must be integrated with the internal safety reporting scheme required by 145.A.202, and conducted in accordance with Regulation (EU) No 376/2014 on the reporting, analysis, and follow-up of occurrences in civil aviation.
Key requirements
The organisation must establish an internal occurrence reporting system to identify, collect, and assess reportable conditions. Reports to the competent authority must be submitted within 72 hours. The regulation also requires reporting to the type certificate holder or supplemental type certificate holder where the occurrence relates to a possible design deficiency. The organisation must maintain records of all occurrences reported and actions taken.
The internal safety reporting scheme under 145.A.202 is the in-house counterpart of this requirement: it must enable the collection and evaluation of occurrences and errors reported by staff, identify any adverse trend or address deficiencies, and protect reporters in line with just culture principles. Occurrences captured through the internal scheme feed the organisation's hazard identification and safety risk management processes under 145.A.200(a)(3).
Common compliance gaps
Under-reporting is the most significant compliance gap in occurrence reporting. Organisations sometimes fail to recognise that a condition is reportable, or maintenance personnel are reluctant to report due to a culture that associates reporting with blame. Late reporting beyond the 72-hour window is also common, particularly when there is uncertainty about whether a condition meets the reporting threshold.
