Warranty Requirement

AS ONE OF THE CONDITIONS FOR THE ENGINE WARRANTY, YOU

MUST OPERATE THIS ENGINE IN ACCORDANCE WITH

SPECIFICATIONS IN THIS MANUAL. YOU ALSO MUST COMPLETE

THE RECOMMENDED SERVICE PROCEDURES IN ACCORDANCE WITH

THE IO-360-N1A ENGINE SERVICE MANUAL FOR THIS ENGINE.

Before Engine Start

Before a newly installed/rebuilt/repaired/overhauled or stored engine can be used for flight, all of the

steps shown in Table 1 must be done in the sequence shown. Otherwise, just do steps 2, 3, 4, and 5 in

Table 1. Refer to sections in this chapter.

THE SEQUENCE OF STEPS IN TABLE 1 MUST BE COMPLETED IN THE

ORDER SHOWN ON AN ENGINE THAT HAS BEEN NEWLY INSTALLED

AND/OR ROUTINELY INSPECTED, REBUILT, REPAIRED, OR

OVERHAULED BEFORE THE AIRCRAFT IS PUT BACK INTO SERVICE.

Step

Engine Run-In / Engine Break-In

Engine run-in is the initial operational check usually done on a new, rebuilt, or overhauled

engine in a test cell at the factory or authorized repair facility (where operating conditions can be

closely monitored). The purpose of this procedure is to ensure that the engine is operating correctly

according to engine specifications. A run-in is already done on all new, rebuilt, or overhauled

engines shipped from the factory. Therefore an additional run-in procedure in the field is not

necessary for these engines. Only the engine break-in procedure will need to be done on engines that

have been shipped from the factory.

Engine break-in (which must be done after engine run-in) is done in the field with the two

progressive flight runs.

 A flight test, refer to the "Flight Test" chapter in this manual

 50 hours of continued flight at power settings alternating between 65% to 75% per the

applicable Pilot Operating Handbook (POH)

NOTICE: Engine break-in must be done on all engines regardless of whether they are new, rebuilt,

and overhauled and shipped from the factory or whether they were overhauled in the

field or had one or more cylinders replaced or piston rings replaced.
