Cessna 404 Titan — Type Certificate

This document outlines the maintenance standards for Auxiliary Aircraft Facilities under the USCG Auxiliary Aviation Program (AUXAIR). It discusses the regulatory framework, including the Federal Aviation Regulations (FARs) that govern the operation and maintenance of Auxiliary aircraft. The document emphasizes the importance of compliance with manufacturer’s recommended Time Between Overhauls (TBO) and the implications of the TBO rule on Auxiliary operations. It proposes a fresh approach to maintenance that focuses on risk management and reliability-centered maintenance principles, aiming to enhance safety and operational effectiveness while reducing costs associated with unnecessary overhauls.

• Auxiliary aircraft must comply with FAA regulations and undergo annual inspections by certified mechanics.
• The TBO rule mandates adherence to manufacturers' recommended overhaul times, which has led to operational challenges for the Auxiliary program.
• Inspections are documented on the ANSC 7005 form, which must be submitted for approval to ensure compliance with regulations.
• The document argues that TBO is not a mandatory requirement for General Aviation and that many aircraft operate safely beyond TBO limits.
• A proposed fresh approach emphasizes condition-based maintenance and ongoing monitoring rather than strict adherence to TBO.
