67.Section 81 provides a power for the Secretary of State to make regulations in order to facilitate the assessment and collection of charges payable under section 73. The regulations may require records of aircraft movements to be kept by operators or owners of aircraft and aerodromes and to be produced on request. These requirements may be imposed regardless of whether or not an aircraft is registered in the UK, is in the UK when the service is provided, or whether or not the relevant services are provided from a place in the UK.
68.Section 82 provides that a person commits an offence if he fails to comply with regulations made under section 82, including where he gives false information. A person also commits an offence if he is in possession of information obtained under the regulations and he discloses it other than in the ways described in subsection (2). Penalties for these offences are set out in subsections (4), (5) and (6) and range from a fine not exceeding the statutory maximum to both a fine and imprisonment of up to two years.
69.Section 83 provides that the Secretary of State may make regulations containing provisions which authorise the detention of, or the sale of detained, aircraft. Where there is default in paying a charge payable under section 73, regulations can provide for the detention and sale of any aircraft in respect of which the charge was incurred or any aircraft operated by the defaulter. Where there is default in complying with a requirement imposed by regulations under section 81, regulations can provide for the detention and sale of any aircraft by the defaulter. Section 84 contains definitions for the purpose of this Chapter.
