1.5Definitions

Note: All definitions used in these regulations have been moved to this subsection for ease of reference. Definitions that are predominantly used in specific Parts remain in those Parts for ease of reference when using a particular Part. In some instances, definitions in the Curaçao Civil Aviation Act may be different than the definition used in these Parts. This is because the laws tend to be written more broadly and may apply to different government agencies within Curaçao. The different government agencies within Curaçao will need to make definitions according to their specific need. Definitions in this Part use the ICAO definition, where available. Where ICAO uses a same term but with different definitions among the Annexes, all ICAO definitions are noted.

1. For the purpose of these regulations, the following definitions shall apply:
   1. Accelerate-stop distance available (ASDA). The length of the take-off run available plus the length of stopway, if provided.
   2. Acceptable. A rule of construction in Part 1.1.1.1 (a)(7) that means the Authority has reviewed the method, procedure, or policy and has neither objected to nor approved its proposed use or implementation.
   3. Acceptance checklist. A document used to assist in carrying out a check on the external appearance of packages of dangerous goods and their associated documents to determine that all appropriate requirements have been met.
   4. Accident. Definition used in a safety management context. An occurrence associated with the operations of an aircraft which, in the case of a manned aircraft, takes place between the time any person boards the aircraft with the intention of flight until such time as all such persons have disembarked, or in the case of an unmanned aircraft, takes place between the time the aircraft is ready to move with the purpose of flight until such time as it comes to rest at the end of the flight and the primary propulsion system is shut down, in which: (i) a person is fatally or seriously injured as a result of: being in the aircraft, or direct contact with any part of the aircraft, including parts which have become detached from the aircraft, or direct exposure to jet blast, except when the injuries are from natural causes, self-inflicted or inflicted by other persons, or when the injuries are to stowaways hiding outside the areas normally available to the passengers and crew; or (ii) the aircraft sustains damage or structural failure which: adversely affects the structural strength, performance or flight characteristics of the aircraft, and would normally require major repair or replacement of the affected component, except for engine failure or damage, when the damage is limited to a single engine, (including its cowlings or accessories), to propellers, wing tips, antennas, probes, vanes, tires, brakes, wheels, fairings, panels, landing gear doors, windscreens, the aircraft skin (such as small dents or puncture holes), or for minor damages to main rotor blades, tail rotor blades, landing gear, and those resulting from hail or bird strike (including holes in the radome); or (iii) the aircraft is missing or is completely inaccessible. Note 1: For statistical uniformity only, an injury resulting in death within thirty days of the date of the accident is classified, by ICAO, as a fatal injury.
