How to stay legal
Your EASA PPL(H) is a lifetime licence which means it doesn't need any administrative action to keep it. It is only valid with an unexpired EASA or JAA class one or two medical certificate. You cannot use a LAPL medical certificate or an NPPL medical declaration with this licence.
All helicopters are type rated. Each type rating lasts for 12 months and must be revalidated by completing an annual type rating licence proficiency check (LPC) at an authorised Registered Training Facility (until 8 April 2015) or Approved Training Organisations (ATO).
