TIME LIMITS AND MAINTENANCE CHECKS
1. GENERAL
This chapter outlines the recommended intervals for overhaul and replacement of components, scheduled
and unscheduled maintenance, and annual inspections. The following Scheduled Maintenance Check
table shows the recommended intervals at which items are to be inspected based on normal usage under
average environmental conditions.
2. ANNUAL INSPECTIONS
As required by Federal Aviation Regulation Part 91.409, all civil airplanes must undergo a complete
inspection each 12 calendar months. This inspection must be performed by an authorized maintenance
person as described in FAR Part 43.3. A signed and dated record must be maintained as each inspection
task is completed. When the last task of the inspection has been completed, the Inspection Report is to be
signed off in the Log Book/Maintenance Record. The inspection items to be covered in the annual inspec-
tion are identical to the 100-hour inspection items.
The inspection interval to the next annual inspection may not exceed twelve calendar months. For Exam-
ple: If an inspection were signed off on 15 September 2005, the next annual inspection would be due and
must be accomplished no later than 30 September 2006. All subsequent annual inspection will be due in
September unless the schedule is reset by performing an annual inspection early.
3. 100-HOUR INSPECTIONS
In addition to the annual inspection, if the airplane is operated commercially (for hire) the airplane must
also have an inspection every 100 flight hours. The 100-hour interval between inspections should never be
exceeded by more than 10 hours, and then only if additional time is required to reach a place where the
inspection can be satisfactorily accomplished.
Additionally, the time the interval was exceeded must be included as flight hours in the next 100-hour inter-
val. For example: If a 100-hour inspection was due at 650 flight hours and was actually signed-off at 658
flight hours, the next 100-hour inspection is due at 750 flight hours, not 758 flight hours. Inspection toler-
ances cannot be accumulated.
4. UNSCHEDULED MAINTENANCE CHECKS
Abnormal airplane operations require special maintenance checks. Definitions and inspection procedures
for hard/overweight landings, overspeed, severe air turbulence, lightning strike, foreign object damage,
and high drag/side loads due to ground handling are listed in Chapter 5-50.
5. SPECIAL CONDITIONS - CAUTIONARY NOTICE
Airplanes operated for Air Taxi operation or other than normal operation and airplanes operated in humid
tropics or cold and damp climates, etc., may need more frequent inspections for wear, corrosion, delamina-
tion, and/or lack of lubrication. In these areas, periodic inspections should be performed until the operator
can set his own inspection periods based on experience.
Note: The recommended periods do not constitute a guarantee that the item will reach the period
without malfunction as in-service factors cannot be controlled by the manufacturer.
“On Condition” items are to be repaired, overhauled or replaced when inspection or perfor-
mance of these items reveal a potentially unserviceable or unsafe condition.
The date on the “ORIGINAL STANDARD AIRWORTHINESS CERTIFICATE,” FAA Form No.
8100-2, which is issued with a new airplane, is to be used as the basis for all inspected com-
ponents listed in the following schedules.
