Each 1000 Hours
Replace engine compartment flexible hoses (fuel, oil, etc.) as required; but not to exceed 1000 hours
time-in-service, eight (8) years, or engine overhaul, whichever comes first.
Overhaul or replace magnetos.
Muffler replacement is recommended at or near 1000 hours time-in-service. (See 78-00-00.)
Clean and lubricate all exterior needle bearings.
Each 1600 Hours
For airplanes in Usage Class “B” (see 57-10-00), which have accumulated 3700 hours total time-in-service
or 3700 hours factored time-in-service; conduct Wing Spar Inspection, 57-10-00.
For airplanes in Usage Class “C” (see 57-10-00); conduct Wing Spar Inspection, 57-10-00.
Each 1700 Hours
If installed, each 1700 hours time-in-service or at engine overhaul, whichever comes first, replace the
Standby Alternator with a new or overhauled unit.
Each 2000 Hours
Each 2000 hours or seven (7) years, whichever occurs first, remove interior cabinets, panels, and
headliner and conduct detailed inspection of aircraft structure (skin, bulkheads, stringers, etc.) for
condition and security. Inspection of structure concealed by headliner may be accomplished by alternate
means (i.e. - through the use of a borescope) without removing the headliner, providing access is
obtained to all concealed areas and borescope provides sufficient detail to adequately accomplish the
inspection.
Each 2000 hours, or as specified in the latest revision of Lycoming Service Instruction No. 1009,
overhaul or replace engine.
At engine overhaul or each 2000 hours, whichever comes first, overhaul or replace alternators.
Recommended Time-Between-Overhaul (TBO) / Reconditioning of Sensenich fixed-pitch metal
propellers is 2000 hours, if propeller does not receive damage requiring immediate attention. Airplanes
in flight school operations or operating from unpaved or poorly maintained runways may expose the
propeller to increased foreign object damage which will require a shorter interval between overhauls.
Reconditioning is removal of fatigued surface metal and accumulated small nicks too numerous to repair
individually. Contact a Sensenich factory approved repair station. (Refer to latest revision of Sensenich
Service Bulletin No. R17.)
Each 6000 Hours
For airplanes in Usage Class “A” (see 57-10-00), which have accumulated 62,900 hours total time-in-service;
conduct Wing Spar Inspection, 57-10-00.
2. Per Calendar Year
Each Thirty (30) Days
If installed, check portable fire extinguisher for condition and charge. Verify nozzle is unobstructed and
safety seal is intact. Determine charge by “hefting”extinguisher.
