8.5. Mandatory aircraft inspections
The following inspections are a minimum requirement for the maintenance of the
aircraft:
25 h inspection (engine only)
It is carried out only once on new aircraft after they have clocked the first 25 hours of
operation. It must also be carried out 25 hours after a major overhaul.
100 h inspection (or annual)
This inspection must be carried out at least once a year even if the aircraft is not
operated for 100 hours during the calendar year. The interval to the next inspection
starts with this advanced inspection.
200 h inspection
The same as the 100 h inspection, this inspection can be brought forward when
fewer hours have been flown. It is performed at every other 100 h inspection.
The TBO times for the engine and propeller must also be observed. Provision is
made for these items in the 100 h and 200 h inspection lists.
The current maintenance list as required by the engine manufacturer is mandatory
for engine maintenance. The inspection items listed here only give a general
indication of the condition of the installation as a whole, not of the engine itself.
These inspections do not supersede any mandatory airworthiness inspections
required by the national aviation authority of the country in which the aircraft is
registered.
The record of the inspections must be documented. A copy of following list in which
the points are ticked off or appropriate notes should be kept as a record.
The detailed maintenance procedures for the CTLS LSA version are described in a
separate maintenance manual. The CTLS is a modern and somewhat complex
machine which requires specific training for proper maintenance. We, therefore
recommend that the 100 h inspections be carried out at Flight Design approved
repair station if possible. Besides that for all maintenance steps the minimum
qualification requirements for the repairman are defined.
