### AIRWORTHINESS LIMITATIONS

A. The airworthiness limitations section is FAA approved. It specifies maintenance required under§§ 43.16 and 91.403 ofthe Federal Aviation Regulations unless an alternative program has been FAA approved. 

### 2. Interchangeability of Parts A. Propeller components used with the 14SF-11 and 14SF-11 E share numerous parts with the same part number. These parts are interchangeable between the two propellers. B. Airworthiness Limitations and Airworthiness Directives listed in manual P5196 also apply to the 14SF-11 E propeller. Please view the Airworthiness Limitations Section (ALS) of Maintenance Manual P5196 for life-limited parts replacement intervals. 

### 3. Major Inspection A. Referto the CHECK section ofthe applicable Component Maintenance Manual for instructions on how to do a major inspection. B. The major inspection intervals in operating hours are listed in Table AL- 1

. It is the responsibility ofthe operatorto monitor flight hours for each component listed in Table Table AL- 1 and to make sure that no component remains in service beyond its listed inspection interval time. C. In addition to the published operating time limitsfor blades and hubs, the requirementfor repetitive Major Inspection (MI) ofthese components will be no laterthan seven (7) years (or 84 months) from the Date Since Installation (DSI). The DSI will begin upon the initial installation afterthe most recent Ml or initial installation after production. D. Propeller blades and hubs must now be subjected to Ml based on published operating time limits forthe component or 7 years from the DSI whichever comes first. Table AL-1.
