Sec.  89.104  Useful life, recall, and warranty periods.



    (a) The useful life is based on the rated power and rated speed of 

the engine.

    (1) For all engines rated under 19 kW, and for constant speed 

engines rated under 37 kW with rated speeds greater than or equal to 

3,000 rpm, the useful life is a period of 3,000 hours or five years of 

use, whichever first occurs.

    (2) For all other engines rated at or above 19 kW and under 37 kW, 

the useful life is a period of 5,000 hours or seven years of use, 

whichever first occurs.

    (3) For all engines rated at or above 37 kW, the useful life is a 

period of 8,000 hours of operation or ten years of use, whichever first 

occurs.

    (b) Engines are subject to recall testing for a period based on the 

rated power and rated speed of the engines. However, in a recall, 

engines in the subject class or category would be subject to recall 

regardless of actual years or hours of operation.

    (1) For all engines rated under 19 kW, and for constant speed 

engines rated under 37 kW with rated speeds greater than or equal to 

3,000 rpm, the engines are subject to recall testing for a period of 

2,250 hours or four years of use, whichever first occurs.

    (2) For all other engines rated at or above 19 kW and under 37 kW, 

the engines are subject to recall for a period of 3,750 hours or five 

years of use, whichever first occurs.

    (3) For all engines rated at or above 37 kW, the engines are subject 

to recall for a period of 6,000 hours of operation or seven years of 

use, whichever first occurs.

    (c) The warranty periods for warranties imposed by the Clean Air Act 

and Sec.  89.1007 for all engines rated under 19 kW, and for constant 

speed engines rated under 37 kW with rated speeds greater than or equal 

to 3,000 rpm, are 1,500 hours of operation or two years of use, 

whichever first occurs. For all other engines, the warranty periods for 

warranties imposed by the Clean Air Act and Sec.  89.1007 are 3,000 

hours of operation or five years of use, whichever first occurs.

    (d) Manufacturers may apply to the Administrator for approval for a 

shorter useful life period for engines that are subject to severe 

service in seasonal equipment, or are designed specifically for lower 

useful life hours to match equipment life. Such an application must be 

made prior to certification.
