## Manufacturer’s Inspection Program 

This is a program developed by the manufacturer for their product. It is contained in the “Instructions for Continued Airworthiness” required under 14 CFR part 23, section 23.1529 and part 25, section 25.1529. It is in the form of a manual, or manuals as appropriate, for the quantity of data to be provided and including, but not limited to, the following content: 

• A description of the airplane and its systems and installations, including its engines, propellers, and appliances. 

• Basic information describing how the airplane components and systems are controlled and operated, including any special procedures and limitations that apply. 

• Servicing information that covers servicing points, capacities of tanks, reservoirs, types of fluids to be used, pressures applicable to the various systems, lubrication points, lubricants to be used, equipment required for servicing, tow instructions, mooring, jacking, and leveling information. 

• Maintenance instructions with scheduling information for the airplane and each component that provides the recommended periods at which they should be cleaned, inspected, adjusted, tested, and lubricated, and the degree of inspection and work recommended at these periods. 

• The recommended overhaul periods and necessary cross references to the airworthiness limitations section of the manual. 

• The inspection program that details the frequency and extent of the inspections necessary to provide for the continued airworthiness of the airplane. 

• Diagrams of structural access plates and information needed to gain access for inspections when access plates are not provided. 

• Details for the application of special inspection techniques, including radiographic and ultrasonic testing where such processes are specified. 

• A list of special tools needed. 

• An Airworthiness Limitations section that is segregated and clearly distinguishable from the rest of the document. This section must set forth— 

This FAA approved owner/operator program can be revised at a future date by the FAA, if they find that revisions are necessary for the continued adequacy of the program. The owner/operator can petition the FAA within 30 days of notification to reconsider the notice to make changes. 

1. Each mandatory replacement time, structural inspection interval, and related structural inspection procedures required for type certification or approved under 14 CFR part 23 or part 25. 

2. Each mandatory replacement time, inspection interval, related inspection procedure, and all critical design configuration control limitations approved under 14 CFR part 23 or part 25, for the fuel tank system. 

The Airworthiness Limitations section must contain a legible statement in a prominent location that reads: “The Airworthiness Limitations section is FAA-approved and specifies maintenance required under 14 CFR part 43, sections 43.16 and part 91, section 91.403, unless an alternative program has been FAA-approved.” 

Any operator who wishes to adopt a manufacturers’ inspection program should first contact their local FAA Flight Standards District Office, for further guidance. 

## Altimeter and Static System Inspections in Accordance with 4 CFR Part 91, Section 91.411 

Any person operating an airplane or helicopter in controlled airspace under instrument flight rules (IFR) must have had, within the preceding 24 calendar months, each static pressure system, each altimeter instrument, and each automatic pressure altitude reporting system tested and inspected and found to comply with 14 CFR part 43, Appendix E. Those test and inspections must be conducted by appropriately rated persons under 14 CFR. 

## Air Traffic Control (ATC) Transponder Inspections 

Any person using an air traffic control (ATC) transponder must have had, within the preceding 24 calendar months, that transponder tested and inspected and found to comply with 14 CFR part 43, Appendix F, and part 91, section 91.411. Additionally, following any installation or maintenance on an ATC transponder where data correspondence error could be introduced, the integrated system must be tested and inspected and found to comply with 14 CFR part part 43, Appendix E, and part 91, section 91.411 by an appropriately person under 14 CFR. 

## Emergency Locator Transmitter (ELT) Operational and Maintenance Practices in Accordance With Advisory Circular (AC) 91-44 

This AC combined and updated several ACs on the subject of ELTs and receivers for airborne service. 

Under the operating rules of 14 CFR part 91, most small U.S. registered civil airplanes equipped to carry more than one
