By Pilar Wolfsteller2021-07-09T00:38:00+01:00 In what one general aviation (GA) lobby group calls “a stunning turnabout”, the Federal Aviation Administration has ruled that owners of certain types of aircraft and flight instructors who teach in those aircraft must obtain additional documentation for flight lessons. The policy, to be published in the federal register on 12 July, is being criticised by flight-training industry as throwing more regulatory burden onto a sector that already faces a raft of rules. The FAA will now require instructors who teach in “experimental-”, “primary-” and “limited-” category aircraft to obtain an exemption called a “letter of deviation authority” – or “LODA” – to conduct those instructional flights, according to an FAA “Notification of Policy”.
