Letters to Owners and Operators (LTOs) were issued by the CAA to owners and operators of

They generally contain information relating to a variety of technical issues, for example, reminders of forthcoming
requirements or clarification of the interpretation of Airworthiness Directives.

from a foreign Aviation Authority or refer to a rule or regulation that is mandatory. The following are still
current, however we no longer issue LTOs, we now issue Safety Notices.
