What this relates to:
Faulty or incomplete maintenance work; foreign objects such as tools or material left in the aircraft after maintenance; problems in planning and monitoring of maintenance activities, use of documentation and compliance with procedures; or production and known design problems. These are reportable incidents that can occur during aircraft or component maintenance, production or design.
Example:
During maintenance, the aircraft technician finds loose terminals. The manufacturer did not tighten them to the prescribed torque.
Remarks on the 2024 figures:
There was a slight decrease in the number of reported maintenance incidents compared to the previous year. The average severity level dropped and about 2% of the cases were classified as higher severity. The reports mainly referred to incorrectly or incompletely installed components and systems, followed by problems in planning and monitoring the required maintenance intervals, which in some cases led to the maintenance intervals being exceeded. Other reports related to faulty inspections and servicing and to regulatory issues.
