Owner-Assisted Annual Inspections: A Collaborative Approach
The term "owner-assisted annual" is a popular one, but it's crucial to understand the FAA's specific guidelines to ensure compliance. While aircraft owners are encouraged be involved in the maintenance of their aircraft, the annual inspection itself carries a specific regulatory weight.
Key Considerations:
• The Inspection Belongs to the IA: The core of the annual inspection, the determination
of airworthiness, must be performed by a certified mechanic holding an Inspection
Authorization (IA). The owner, unless they are also an IA., cannot perform any part of the inspection that involves making a judgment about the condition of a component or
system.
• Permissible Owner Assistance: Owners can, under the supervision of the IA, perform a
variety of tasks that fall under the umbrella of maintenance, This can include opening
inspection panels, cleaning the aircraft and engine, changing the oil and spark plugs, and other preventive maintenance tasks as outlined in FAR Part 43, Appendix A.
• Clear Logbook Entries: It is vital that all maintenance performed by the owner is
properly documented in the aircraft's logbooks. The IA will then sign off on the annual
inspection, certifying that they have personally performed the inspection and found the
aircraft to be in an airworthy condition. The owner's maintenance entries should be
separate from the IA's sign-off inspection.

Light-Sport Aircraft (LSA): A Growing Sector
The Light-Sport Aircraft category has its own set of rules for maintenance and certification, blending aspects of both standard category and experimental aircraft.

Maintenance and Inspections:
• Special Light-Sport Aircraft (S-LSA): These are factory-built aircraft that meet an
industry consensus standard (ASTM). Maintenance on S-LSA must be performed in
accordance with the manufacturer's maintenance and inspection procedures.
º The annual condition inspection can be performed by an A&P mechanic or a
Light Sport Repairman with a Maintenance rating (LSRM).
º The 100-hour inspection (if required for rental or instruction) can also be
conducted by an A&P or an LSRM.

About Aircraft Maintenance and Inspections
Aircraft maintenance is a multifaceted discipline crucial for ensuring the continuous airworthiness and safety of every flight. It encompasses a broad range of activities, from routine servicing and preventative measures to complex repairs and overhauls. This includes everything from checking fluid levels and replacing worn parts during line maintenance, to extensive dismantling and inspection during heavy maintenance, often involving significant downtime in specialized facilities. The overarching goal of aircraft maintenance is not only to prevent mechanical failures and ensure peak performance but also to maximize the operational lifespan and resale value of the aircraft, all while adhering to the stringent regulatory standards set by aviation authorities like the FAA.
Integral to effective maintenance are thorough aircraft inspections. These systematic examinations are mandated at various intervals, such as pre-flight checks, 100-hour inspections for aircraft used for hire, and annual inspections. Each inspection type follows a detailed checklist, covering the airframe, engines, electrical systems, avionics, landing gear, and control surfaces. The purpose of these inspections is to identify any signs of wear, damage, corrosion, or potential malfunctions before they can compromise safety or lead to more significant issues. By meticulously inspecting every component and system, our technicians ensure that each aircraft consistently meets the rigorous safety requirements and is ready for safe and reliable operation.
