Classifying Damage to Composite Parts
See section 51-01 for information about non-destructive inspection of composite structures for invisible
damage.
Damage class 1:
•
Large scale destruction, requiring a partial reconstruction or large-scale repair of the component
•
Any destruction over 300 mm in any direction
•
Any damage to a spar is automatically large-scale destruction and hence class 1
WARNING: The airplane must not be operated!
Damage class 2:
•
Damage to structures where the holes or fractures extend through a sandwich component, less than
300 mm in any direction.
Subject to review by a suitably qualified person, the airplane may be ferried to a repair station.
WARNING: Aerobatics are not permitted!
Damage class 3:
•
Damage to structures with small holes or cuts in the outer skin, (less than 15 mm diameter or length)
not extending into either the sandwich or the inner skin
•
Indentation damage, where a tap test (see 51-01) does not reveal any disbonds
Subject to result of the assessment, the airplane may be flown as normal until the next service when the
damage must be reassessed in accordance with this manual.
Damage class 4:
•
Erosion or small depressions or scratches or nicks not accompanied by fractures
•
Any damage to non-structural fairings is automatically class 4
The airplane may be operated as normal.
