Minimum Inspection Programme for ELA1 sailplanes and ELA1 powered sailplanes not involved in commercial operations
To be performed:
—	every annual/100 h interval (for Touring Motor Gliders (TMG)), whichever comes first; or
—	every annual interval (for other than TMGs).
A tolerance of one month or 10 h, as applicable, may be applied. However, the next interval shall be calculated from the date/hours originally scheduled (without the tolerance).
Note 1: 	Use the manufacturer’s maintenance manual to accomplish each task/inspection.
Note 2:	In the case of TMGs, it is acceptable to control the hours of use of the aircraft, engine and propeller as separate entities. Any maintenance check to be done between two consecutive annual/100 h inspections may be performed separately on the aircraft, engine and propeller depending on when each element reaches the corresponding hours. However, at the time of the annual/100 h inspection, all the elements must be covered.
Note 3: 	Proper operation of backup or secondary systems and components should be included for every instance where a check is performed for improper installation/operation.
