Cessna released SEL-05-03, titled “TIME LIMITS/MAINTENANCE CHECKS - CHAPTER 4 AIRWORTHINESS LIMITATIONS ADDED TO THE MAINTENANCE MANUAL”.
While the title of this Service Letter may cause some confusion since Time Limits and Maintenance Check is the title of Chapter 5 and remains the location of the manufacturer recommended time limits and maintenance checks; this Service Letter applies to all Cessna 1996 and on Single Engine Aircraft (172R/S, 182S/T, T182T & 206H/T206H) and serves as notification that an airworthiness limitations chapter has been added to the maintenance manual.
To further explain; Chapter 4 gives the FAA approved replacement times and inspection intervals for components of the airplane. The information provided in this chapter is a limitation on the airworthiness of the airplane. Failure to comply with the requirements defined in Chapter 4 will cause the airplane to be un-airworthy.
The only component currently listed in Chapter 4 on the above airplanes is the Oil Pressure Switch, Part Number: 83278 which must be replaced every 3000 hours. This switch is also the subject of Airworthiness Directive AD 2000-04-01.
