ZENAIR CH2000 SERVICE MANUAL
________________________________________________________________________
Calendar Inspection Requirements
a Perform a visual inspection of the pitot-static system connection Tygon splice at the
wing root, for security and condition, every 12 months.
b. Perform a visual inspection of the wing fuel tank compartments (if wing fuel tanks are
installed) for corrosion, cracking, etc every 5 years.
UNSCHEDULED INSPECTIONS
Unscheduled inspections must be performed anytime that unusual operating conditions are
encountered which may affect the integrity or airworthiness of the aircraft. Actions to be taken following the
reporting of such events are as follows:
INSPECTION AFTER SPECIFIED MAINTENANCE ACTIONS
Inspections are to be performed one time only, following the performance of the following tasks:
Installation of new alternator -
drive belt.
Check belt for condition and tension at 25 hours of belt
operation. (Ref. Lycoming Service Instruction #114)
Installation of new, -
re-manufactured or overhauled engine.
Perform a 50-hour engine inspection (Ref. Section 4 of
Lycoming Operator’s Manual).
CORROSION CONTROL
To avoid the deterioration of the CH2000 aircraft due to the effects of corrosion, monitor the
condition of protective coatings on exterior and interior surfaces. If damage to coatings is found, restore
surfaces prior to the occurrence of damage caused by environmental effects.
INSPECTION SCHEDULE
The required inspection tasks and their intervals are listed in Table 1. The tasks are placed in seven
groups: Propeller, Engine, Cabin, Landing Gear, Wing, Fuselage and Empennage.
The first column of Table 1 states the task to be performed, the second column states the applicable
references(s). The third column is divided into four sub-columns, each of which corresponds to an
inspection interval. The last column may be used to verify that a task has been completed. Perform the
stated tasks at the intervals shown when a plus (+) symbol is shown in an interval column. A minus (-)
symbol indicates no maintenance action is required. Tasks may be performed sooner but not later than the
stated intervals. If done sooner, tasks must next be performed at the stated interval (e.g. at 790 flight hours
airframe time, a 100 hour task is performed 10 flight hours before it is due. It must next be performed 100
hours later, at 890 flight hours (or sooner).
Operational checks are tasks that determine that an item is fulfilling its intended purpose. No
verification of meeting tolerances is required.
Functional checks are tasks which determine if one or more functions of an item are performing
within specified limits. Quantitative checks must be performed.
Useful Note: The 50 hour inspection has a tolerance of + 16% (ie between 42 and 58 hours)
