CESSNA AIRCRAFT COMPANY MODEL 100 SERIES (1963 - 1968) SERVICE MANUAL
INSPECTION TIME LIMITS - STRUCTURE
1. Scope A. This provides the mandatory times and inspection time intervals for components and airplane structures. This section also gives the required details to monitor them using scheduled inspections. This section applies to items such as fatigue components and structures, which are part of the certificationprocedures. Refertothedescriptionparagraphbelowfordetailedinformationcon cerning each of these sections. NOTE: The time limits and maintenance checks listed in this section are the minimum requirements for airplanes operated under normal conditions. For airplanes operated in areas where adverse operating conditions may be encountered, such as high salt coastal environments, areas of high heat and humidity, areas where industrial or other airborne pollutants are present, extreme cold, unimproved surfaces, etc., the time limits should be modified accordingly. NOTE: The inspection guidelines contained in this section are not intended to be all-inclusive, for no such charts can replace the good judgment of certified airframe and power plant mechanics in performance of their duties. As the one primarily responsible for the airworthiness of the airplane, the owner or operator should select only qualified personnel to maintain the airplane. 2. Inspection Requirements A. Twotypesofinspectionrequirementsareavailablebasedonoperating usageandtwoadditionaltypes of inspections are available based on operating environment. (1) Operating Usage (a) Severe Usage Environment 1 If the average flight length is less than 30 minutes, then you must use the SEVERE inspection time limits. 2 If the airplane has been engaged in operations at low altitudes such as pipeline patrol, fish or game spotting, aerial applications, police patrol, sightseeing, livestock management, etc. more than 30% of its life you must use the SEVERE inspection time limits. 3 Airplanes which are equipped with floats or skis must use the SEVERE inspection time limits. (b) Typical Usage Environment 1 If neither 2(A)(1)(a)(1) or 2(A)(1)(a)(2) or 2(A)(1)(a)(3) above applies, the TYPICAL usage environment applies. (2) Operating Environment (a) Severe Corrosion Environment 1 If the airplane is operating more than 30% of the time in a zone shown as severe on the corrosion severity maps in Section 2A-30-01, then the SEVERE CORROSION environment time limits apply. (b) Mild or Moderate Corrosion Environment 1 If 2(A)(2)(a)(1) does not apply, then the MILD/MODERATE CORROSION environment time limits apply. B. After the operating usage and the operating environment are determined, make a logbook entry that stateswhichinspectionschedules(TYPICALorSEVEREoperatingusage andMILD/MODERATEor SEVERE operating environment) are being used.
