Nimbl Releases Updated Part 91 LOA Guide to Help Corporate Flight Departments Navigate FAA Authorization Requirements
Why It MattersCompliance guidance tools reflect how corporate flight departments increasingly rely on third-party expertise to translate complex FAA authorization rules into usable operational checklists.
What happened
Nimbl, a business aviation software and safety management platform, has released an updated Part 91 Letter of Authorization (LOA) Guide intended to help corporate flight departments determine which FAA authorizations apply to their operations and what documentation is required before beginning an application.
The guide covers the types of LOAs operators may need, the associated requirements and documentation, key elements of an application, expected turnaround times, and additional resources that may be required during the process. Nimbl describes the guide as free and says its purpose is to help flight departments identify potential authorization requirements before they become an obstacle to a planned operation.
"Our team loves to stay on top of regulations so our clients don't have to," said Mark Baier, CEO of Nimbl. "Our aviation experts spend their time understanding complex FAA requirements and turning them into information operators can actually use." Nimbl says it has supported more than 4,700 operators worldwide over 30 years through its safety management systems, procedures manuals, and compliance support services.
Industry impact & what to watch
Corporate flight departments operating under Part 91 regularly encounter authorization requirements tied to specific operations or capabilities, and assembling the documentation for each LOA adds complexity to keeping an aircraft ready for business use. A guide that lays out which authorizations apply, what paperwork each one needs, and how long approval typically takes addresses a recurring administrative friction point rather than a one-off problem.
This is the kind of support role third-party compliance and safety management providers occupy in business aviation: flight departments outsource the work of tracking regulatory detail so operational readiness doesn't stall on paperwork. Whether this particular guide changes how quickly departments secure authorizations, or simply makes existing requirements easier to find, isn't something the material settles.
