Every year around 100 newly-constructed aircraft are added to the LAA fleet, with members generally taking around 1 to 4 years to complete their kit projects. A whole range of aircraft is available to build, from single-seaters to four-seaters, aerobatic to amphibian, and WWI replica triplanes to gyroplanes. LAA is tasked with ensuring that the designs members build meet minimum airworthiness requirements, appropriate to the type. A link to the list of LAA accepted types can be found below, along with a list of plans-built types and new types that are being worked on.
Proposals for accepting other designs of aircraft can be put to the LAA, and a number of such types are accepted each year following a review of their airworthiness, amongst other things. This requires a member to champion the type through the process, arranging for the necessary technical information to be passed to the Engineering department and to build and test the first example.
Similarly, it is possible for a member to build an aircraft of their own design. LAA provides support for this (see the Designing aircraft section), but due to limited resources only the most promising/developed designs can be advanced through the system.
