MAINTENANCE MANUAL 

14SF-11E 

AIRWORTHINESS LIMITATIONS 

A. The airworthiness limitations section is FAA approved. It specifies maintenance required 

under§§ 43.16 and 91.403 of the 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. Refer to the CHECK section of the 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 of the operator to 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 limits for blades and hubs, the requirement for 

repetitive Major Inspection (MI) of these components will be no later than seven (7) 

years (or 84 months) from the Date Since Installation (DSI). The DSI will begin upon the 

initial installation after the 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 for the component or 7 years from the DSI whichever comes first.

5. Critical Parts Inspection 

A The components listed in Table AL- 3 require inspection to assure continued 

airworthiness. When they reach the number of flight hours listed in the table, the 

components must be removed from service and the inspections must be done. The flight 

hours listed represent time new or time since last inspection. 

B. It is the operator's responsibility to monitor flight hours for each component listed in

** Do the inspections for this component in accordance with 

CMM 61-13-06 or the CHECK section of chapter 61-10-00 of this 

manual. 

6. Special Instructions 

A If there is evidence of overspeed, foreign object damage, lightning strike, or overtorque, 

then do the inspections in the CHECK section of chapter 61-10-00 of this manual. 

Complete the appropriate report (Figure 502, Figure 504, or Figure 505) and send a 

copy to the Hamilton Sundstrand address specified on it.
